Work Experience – More Detail Analytical Chemist/Section Head/Local Quality Manager Eurofins Scientific, 445 New Cross Road, SE14 6TA 1997 – 2001 At Eurofins Scientific which was the United Kingdom’s largest public analysts laboratory. Throughout my period of employment at Eurofins I worked within the water analysis section analysing a wide variety of different types of potable waters, wastewaters and industrial waters as well as water associated materials. During my time at Eurofins my duties within the water analysis section varied to include:

• The management of sampling programmes and sampling for some of Eurofins largest clients. • Method development to successfully obtain UKAS accreditation for all of the methods that

the water analysis section utilised.

My success at obtaining UKAS accreditation for the water analysis section meant that i became the head of the section and also took on additional duties as Local Quality Manager, supporting the Group Quality Manager and take on the responsibilities for all analysis sections within the New Cross laboratory. Further successes in my roles saw me given control over the metal analysis section conducting chemical analysis of food based samples as well as the water based samples that I had been limited to. Site Chemist/Service Operations Manager for British Forces South Atlantic Islands ULG Northumbrian/SATEC, Mount Pleasant Airfield, Falkland Islands, FIQQ 1ZZ 2001 – 2006 During my tenure in the Falkland Islands I worked for ULG Northumbrian (2001- 2004) and for SATEC (2004-2006) managing the water and wastewater facilities for the Ministry of Defence and British Forces South Atlantic Islands. The scope of the posting stretched to provide a consultant chemists service similar to that of Public Analyst in the UK. The responsibilities in the post covered:

• The management of a team of 15 operators who ran the Falkland Island water treatment assets.

• The complete contractual management of all water and wastewater treatment facilities at Mount Pleasant Airfield and Mare Harbour. This included the water treatment works, wastewater treatment works, swimming pool, water distribution network, wastewater collection network and a total of nine pumping stations.

• Management of the MOD water resources • Water and wastewater treatment works on four different remote outstations • Duty of care for the potable water supply at two Falkland Island settlements at which military

personnel were located. This included liaising with the Falkland Island Government and helping them to bring the water supply to standard.

Page 4

• Authorising engineer for military assets authorising them to supply water fit for human consumption. This included resolving issues with the military assets when there were any and making sure that the assets were fit to supply water.

• Any issues that were raised in terms of the water, wastewater or the general environmental impact that the MOD had on the Falkland Islands assisting the Defence Estates branch and the Theatre Environmental Protection Officer in any chemical or biological issues.

• Incident management - There were several incidents during my tenure in the Falkland Islands that expanded my knowledge and experience. These included:

o Conducting a trial into the use of Ferric Sulphate as an alternative coagulant to aluminium sulphate.

o The management of the potable water network to reduce leakage from approximately 75% at the beginning of my tenure to approximately 15% leakage at the lowest point but also identify the root cause of the problem so far as the mains were over-pressurised and leakage could be reduced utilising pressure reducing valves.

o The management of an incident that saw 10,000 litres of diesel to the wastewater treatment works and the subsequent remediation of the treatment works.

o The investigation and management of an outbreak of E.Coli at one of the Falkland Island Settlements tracing the source of the E.Coli and liaising with the Falkland Island Government to resolve the issue.

• Devising, in conjunction with the MOD Theatre Environmental Protection Officer, a series of discharge permits for MOD activities in the islands.

• Resolving issues with the MOD assets when they arrived in theatre with contamination of their water supplies and acting as authorising engineer to certify that their water supplies were fit for human consumption.

• The design of a new potable water treatment works for Mount Pleasant Airfield. Further details of three of these projects are provided below Remediation of the wastewater treatment works This project was initiated very quickly due to the accidental discharge of at least 10,000 litre of diesel fuel to the MPA wastewater treatment works. The discharge was accidental and initially to a fuel interceptor. However, poor initial design of the fuel interceptor system meant that the interceptor, when full, discharged to the foul drain. This meant that around 10,000 litres of diesel fuel was discharged over night to the wastewater treatment plant (as the plant was not manned 24 hours a day). The main aims of this project became:

1. Remove the diesel fuel from the wastewater treatment plant. 2. Dispose of the diesel fuel in an effective and environmentally responsible manner. 3. Remediate the wastewater treatment plant so as to bring it within discharge consent limits. 4. Evaluate any and all environmental damage caused by the accidental discharge and remediate

where possible. 5. Maintain Health & Safety of at all times

The constraints of this project were:

1. There was nowhere to dispose of the diesel fuel.

Page 5

2. There were no other sewage treatment plants locally that could be used to reseed the MPA wastewater treatment plant.

My responsibility in this project was in managing the project and devising a financially feasible solution to remediate the plant by creating a costed remediation package and managing the project The first aim was simply completed by manually removing as much of the diesel contaminated sludge from the plant as possible by using gully-suckers and the bases sewage sludge bowser. These were then cleaned themselves so they could be used for their normal duties. Risk assessments and method statements had to prepared for the personnel involved in this task. The diesel contaminated sludge was put in barrels and shipped to the United Kingdom for hazardous waste treatment. This was the only option available due to the nature of the contaminant. As delivery ships regularly returned to the United Kingdom there was no major environmental impact due to the transport of all of the contaminated sludge. The remediation of the wastewater treatment plant was a much larger challenge. As there was no local wastewater treatment plant to re-seed the MPA activated sludge wastewater treatment plant. The remediation of the plant was achieved in two fold manner. Media was sought from the United Kingdom in order to achieve two things. The first being the degradation of the diesel that had not been mechanically removed and secondly to provide a growth medium for the bacteria that was still entering the plant on a day today basis (the normal plant influent). However this was not sufficient on it own to remediate the plant, so other sources of influent were sought. In this I contacted local farmers to source faecal matter from the islands sheep and cattle population. Although not ideal this provided a good substrate to remediate the plant. In addition to this any military ships entering port were asked not to discharge there sewage sludge at sea in international waters but to bring it into port where it would be collected for use in the MPA wastewater treatment plant The use of the media to degrade the diesel was applied directly to the plant and the contaminated pumping stations. Once it had been confirmed that there was no more diesel within the system, I had to come up with a strategy for adding the growth media to the wastewater system. This involved using the pumping stations as mini bio-reactors and pre-reacting the sewage prior to it reaching the main plant. This very successfully re-mediated the wastewater treatment plant at MPA. During the entire incident the environment also had to be protected. I was also charged in coming up with an environmental monitoring programme in order to assess the initial damage from the discharge to the plant and any continuing damage whilst to discharged to the environment (as the normal influent still had to be treated). The worst of the initial environmental damage was limited by a plan to use local ponds and the ditch system of the base. A distribution system was set up in conjunction with the Royal Engineers to discharge unpolluted water and mix it with the polluted water in order to “dilute and disperse” as much of the pollution as possible. This was done for the first week after the incident and managed to reduce the pollution effects by approximately 80% (measured by Biochemical and chemical oxygen demand measurements in addition to dissolved oxygen measurements). I also had to develop a financial cost plan for the remediation project. This had to be submitted for approval by the military, before and actions were taken. The plan also had to be submitted to my client (who the water and wastewater contract was subcontracted from). After the incident had finished and any attention by the local press had been mitigated key learning points from the incident were taken

Page 6

• Future plans to ensure a similar incident could never happen again were undertaken by purchasing a storing remediation kits on-site to protect the biology in case of further contamination incidents.

• All of the fuel interceptors were disconnected from the foul main, • A military spill plan was written to educate the military that a discharges to drain would affect

the wastewater treatment plant and actions that they should take in the event of a spill. This ensure the correct communication in the event of a spill

Management of an E-Coli outbreak at Fox Bay. Fox Bay is one of the major settlements on West Falkland at which the military hold a presence. The water systems are owned and operated under the Falkland Island government. I tested the water at Fox Bay monthly on behalf of the military under the auspices of the military’s duty of care to their staff. On testing the water one month it was found that the entire water treatment system was contaminated with E.Coli. This became a very public issue and was reported in the local press (see the article below)

Figure 1: Report from the Penguin News on the Fox Bay E-Coli outbreak. On discovery of the outbreak the military hierarchy were informed and a shipment of bottled water was immediately sent to military personnel at the village in order to protect the militaries duty of care towards their employee’s. At the same time the military informed the Falkland Island chief medical officer and the Falkland Island government. I was then requested by both the Ministry of Defence and the Falkland Island Government to trace the source of the problem. This required quick reactions as a sample programme in order to trace the problem had to be devised. This tracked the problem to the Falkland Island government water storage tanks and found the problem to be due to improper protection of the water supply tanks. As can be seen in the photographs below there were numerous possible points of contamination in the tanks:

Page 7

Figure 2 Falkland Island Government water storage tanks. In addition to finding the source of the outbreak both the military and the Falkland Island government requested that I submitted a report of recommendations to make sure that this incident did not happen again. The report recommended that repairs be made to the storage tanks to ensure that there were no valves that risk the security of the tanks and also that the tanks be fenced off so that local wildlife and farm animals could not gain access to the tanks. By quickly reacting to this situation the military and Falkland Island government duty of care was protected and any fallout from adverse publicity was minimised. The learning points from this incident where for the correct protection of the water supply especially where the supply is un-chlorinated and the need for the correct maintenance of raw water supply pipelines. Preliminary design for a new water treatment facility for MPA. Whilst working for SATEC at MPA I was approached by military personnel for an initial design for a new water treatment facility for the base and asked to assess if the military’s budget of £3 million was sufficient for the task. I was given a number of constraints for the project which included adding to the new design a security of supply which wasn’t present in the initial plant design. This issue particularly referred to the deliberate addition of a biological agent to the water treatment system. The new design also had to address problems which weren’t designed into the plant when initially built just after the Falkland Island conflict. The new design also had to take into account the resources available on site and that limited power generation was an issue on the base as a result the design was not to include any processes that have a particularly high energy consumption (i.e. the use of ozone was impractical due to electrical consumption issues as well as health and safety issues). As the nature of the project was so technically complicated the contract was secured directly by my company at the time through negotiations with military personnel. The military were particularly keen

Page 8

to engage my company in the contract as they were the initial designers and builders when the first plant was built. Several options and their advantages and disadvantages as well as a rough expected life were put to the military. These are detailed below:

1. The first option was to revamp the current plant to bring it back to its initial specifications. This was the cheapest option and also had the shortest expected lifespan. It involved repairing all of the problems with the current plant and did not allow for any future expansion of the base. After proposals were submitted it was found out that expansion was planned and thus this option became infeasible.

2. The second option was to design and build a new plant but still under the current operation and maintenance system (i.e. a manually controlled plant).This allowed a plant to be built and operated under manual control. This also meant that current staffing levels could be kept and the plant be manned 24 hours a day and maintained fully. The benefits of this option were that it could take into account any future expansion of the base and take into account security constraints put on the project by military security teams

3. The third option was to install a state of the art water treatment plant with fully automatic systems. This meant that the number of personnel operating the plant could be minimised and operational costs kept to a minimum. A SCADA system would be used to control the plant and record all of the operational data. The disadvantage of this option was the reliability of an automated system and the availability of spare parts. If operational staff were decreased in number and a problem developed with the plant, it may not be able to be repaired, especially due to the availability of replacement parts. All of these options were evaluated and the second option was chosen. The preliminary designed was developed by myself and SATEC’s operations director. Wesolved numerous problems that the current plant had in terms of the environment, health and safety, and quality management systems. The initial flow diagram for the new water treatment plant for MPA is shown in figure 3.

Process Engineer Grontmij, Grove House, Mansion Gate Drive, Leeds, LS7 4DN 2007 – 2010 At Grontmij I worked as a Process Engineer gathering experience in both potable and wastewater as well as designing projects for the investigation of new process technologies and investigation programmes. In addition to this I provided technical support to clients such as the States of Jersey and defensive research for private companies. I also commissioned treatment works in Huddersfield for Yorkshire Water and in Craven Arms for Severn Trent Water. Key projects whilst working at Grontmij included:

• Investigations into the optimisation of United Utilities treatment works at Wigan resolving issues with the biological filters, the UV system and the sludge treatment.

• Works expansion projects due to growth or quality at Irthington, Aikton & Little • Bampton and Strines • Development of technological research projects at Windermere and the Mersey Estuary. • Process commissioning of an activated sludge plant and sludge thickening facility in

Huddersfield for Yorkshire Water and a biological nutrient removal alternating double oxidation ditch Craven Arms for Severn Trent Water.

• Process support to the States of Jersey including the development of the short, medium and long term solutions for their treatment works at Bellozanne and resolving issues with their odour treatment system.

• Asset assessment and optioneering for industrial clients. • Defensive research for a private client investigating the impact of food waste disposal units

on small and large wastewater treatment works in Ireland in response to an Irish directive to ban the use of the units.

• Potable and wastewater support to Scottish Water identifying treatment • solutions for the Q&S III programme.

Whilst at Grontmij I also provided technical support to the operational side of the business conducting presentations and developing technical bids for a number of different clients including research projects for United Kingdom Water Industry Research looking into the potential of OPRA-PBC and the Dangerous Substance Daughter Directive of the Water Framework Directive. Of these projects that I worked on three of these are expanded upon in further details Wigan Wastewater Treatment Works for United Utilities, Huddersfield for Yorkshire Water and Bellozanne for the States of Jersey Wigan Wastewater Treatment Works Wigan treatment works had a population equivalent of approximately 400,000 person equivalents of which half of the load was from trade customers. Figure 4 shows an overhead photograph and a process flow diagram of Wigan wastewater treatment works.

Page 10

Figure 4: Wigan wastewater treatment works The treatment works process was currently primary sedimentation followed by biological filtration in alternating double filtration with intermediate and final humus settlement followed by blending with the effluent from a nearby treatment works followed by UV filtration as the treatment works had a coastal influence. An initial assessment of the treatment works identified that the secondary treatment process was grossly overloaded causing overgrowth on the biological filter beds. Problems with the pathogenic inactivation by UV despite the correct UV dose being applied. Finally there were problems with the sludge centrifuges due to incorrect sludge consolidation and incorrect polymer dosing causing the inefficiencies in the sludge dewatering. Figure 5 shows photographs of the problems at Wigan wastewater treatment works.

Page 11

Figure 5 (Top Left to Bottom Right) Overgrowth of filter beds, the UV system, broken hatches on consolidation tanks, non-functioning consolidation tank valves, sludge centrifuges. The problems with the works were diagnoses as insufficient secondary treatment capacity which potentially were causing problems with particle shielding of the UV process due to carry over of turbid particles and insufficient thickening in the consolidation tanks creating a thin sludge for dewatering coupled with incorrect polymer dosing creating steric repulsion in the dewatered sludge creating foaming effects. The solutions that were proposed was a series of options to increase the secondary treatment capacity by using a number of different options including partially converting the rock media to plastic and increasing the organic capacity to the construction of a sidestream ASP. The design also had to take into account the design envelope of the BAFF plant that was in construction as the ammonia consent was being lowered. Investigation into the UV system found that the problems with the UV were being caused either particle shielding or preferential UV absorption in the wastewater effluent due to a dye manufacturer discharging to the works. The solution was to give United Utilities a methodology of investigation to discover whether it was the shortcomings in the process or the dye manufacturer. The investigation allowed UU to discover that the dye manufacturer was the cause of the insufficient bacteriological inactivation and a pre-treatment plant utilising electro-coagulation resolved the issue. The solution to the sludge treatment process problems was relatively simple, insofar as it was recommended that the consolidation tanks be repaired with new hatches and new consolidation valves and chains fitted to the valves for ease of operation. The stepped approach to the solution also allowed for a potential thickening stage using drum thickeners. This method would allow one of the sludges to be thickened prior to the dewatering stage. This would allow for a consistent sludge thickness to be maintained at approximately 3-4% instead of 0.5-1% that had been previously achieved. This would also allow more efficient polymer dosing as the solids applied would be more controlled, this in turn would eliminate the foaming due to steric repulsion and prevent polymer wastage. From the project at Wigan I increased my wastewater treatment knowledge with better understanding of the operational side of biological filters, UV and sludge systems and my awareness of the complexities of large works was increase. It also allowed me to refine my design capabilities.

Huddersfield Wastewater Treatment Works The Huddersfield Complex is one of Yorkshire Water’s most complicated treatment works comprising of six different treatment works sites with six different treatment works treating a population equivalent of approximately 350,000. Figure 6 shows the six different treatment works

Figure 6: Huddersfield Complex - Deighton Primary Treatment (Top Left), Colne Bridge BAFF plant (Top Right), Upper Brighouse, Lower Brighouse, Heaton Lodge and above Cooper Bridge (Bottom picture L-R and above). Figure 7 shows how those treatment works are arranged in terms of the treatment flow.

Page 13

Figure 7: Treatment works layout for the Huddersfield Complex Whilst working at Grontmij one of the projects that I worked on was the design and commissioning of a new treatment works in line with the freshwater fisheries directive that saw the design and build of a new activated sludge plant for the Huddersfield Complex at Lower Brighouse wastewater treatment works and de-commissioning of the filter works at Cooper Bridge. I was the process engineer on the later stages of detailed design for this project finalising the last design details such as the size of the selector tank in line with the principles of floc loading selector design after Eckenfelder. As part of this project I was in charge of the process commissioning plan devising how to commission the plant. We realised significant savings on the project by backfeeding the seed sludge from the sequencing batch reactor across the road at Upper Brighouse. This was done by artificially raising the mixed liquor in the sequencing batch reactor mixed liquors and when the project was ready to start seeding wasting the sludge to one of two newly constructed sludge tanks (as part of the project) and

Page 14

feeding this back to the selector of the new activated sludge plant. In this way it was possible to biologically commission the activated sludge plant within 28 days with a total of 12,000 kg of dry solids or the equivalent of 40 sludge bowsers of sewage sludge. The remaining sludge was generated by utilising the biological process. The rapid start of the biological process made significant cost savings. The speed of the biological commissioning also allowed for a rapid de-commissioning of the biological process at Cooper Bridge as a nitrifying community rapidly developed on the Heaton Lodge filter bed as load was removed from this biological process. There were setbacks in the commissioning of the treatment works due to instrumental problems caused by incorrect positioning of analytical monitors in areas which were not quiescent enough. This was a major learning point taken from the project. Expectation of the unexpected is very important as one of the industrial customers discharged cyanide to the treatment works during commissioning. The biological process had been established to extent that the damage that was done was minimal. After the biological process was started I worked with the mechanical and electrical teams proving the different elements of the treatment works in the plant tests as to the functionality of the treatment works and proving the operability. This gave me a chance to work with software integrators and with the experience of the biological commissioning of the treatment works make minor changes to the SCADA interface to make the treatment works more operable. This included feeding the cumulative flows through to the SCADA trending and resetting them automatically at midnight each day. The benefit of this is in the current operability where flows can automatically be read each day which allows immediate identification of the different flow conditions each day. Away from the site at Lower Brighouse I assisted in the commissioning of a drum thickening facility over at Upper Brighouse partly managing the reliability process. There were numerous issues centered around the drum thickeners including problems with the washwater quality which were initially resolved by over-pumping from the effluent chamber of the Sequencing Batch Reactor present and subsequently solved by the installation of a Boll type self cleansing filter. The entire commissioning process had to be achieved whilst maintaining the consent of the Huddersfield complex and this was maintained by managing a significant sampling programme that I devised and agreed with Yorkshire Water Project engineers. This resulted in the new modified consent being taken one month early which was of significant benefit to Yorkshire Water. The Huddersfield project received a Certificate of Excellence from the Institute of Civil Engineers for the sustainability considerations that were built into the design of the treatment works. Process Support to the States of Jersey Grontmij acted as technical consultants to the States of Jersey and to their treatment plant at Bellozanne (see figure 8)

Page 15

Figure 8: Bellozanne WwTW, Jersey Grontmij were asked to develop a 25 year plan for Jersey wastewater treatment assets and to resolve historical issues with compliance due to the Pegazur process that had been installed allowing for insufficient nitfication and de-nitrification. As such a short to medium term plan was developed by myself utilising the Cleartec process converting the lanes to an IFAS process whilst also operating at a low residual dissolved oxygen concentration which meant that the historical foaming problem was resolved. This had to take into account the long term plans of replacing the treatment works at Bellozanne In the medium term I was the process engineer re-designing the sludge treatment system re-utilising the current assets and re-designing the lime addition system to create an advanced treated sludge that could be used on Jersey’s agricultural land bank. Additionally in the medium term I was the process engineer in the re-design of the digestion system, potentially looking at the Biothelys process as a replacement to sludge conditioning by lime. Bellozanne’s sludge production was too small too economically support advanced digestion and so this option was discounted. In Jersey I was also the process engineer on several other projects including the resolution of an odour treatment scheme.

Senior Project Engineer (Process) Yorkshire Water Services, Western House, Halifax Road, Bradford, BD6 2LZ 2010 – 2012 Whilst at Yorkshire Water I worked on the wastewater treatment asset policy treatment team working in several different areas of the business. This included:

• The development of the Yorkshire Water Asset Standards • Process support to the operational teams at 5 of Yorkshire Waters largest wastewater

treatment works, namely the treatment works at Huddersfield, Bradford-Esholt, Holmfirth -Neilley, Halifax-Copley and Harrogate South

• Process support to the smaller treatment works covering North Yorkshire. • Project support to the asset delivery unit helping to delivery Yorkshire Water’s • AMP 5 Capital delivery program. • Other process based requirements as required by the business.

Asset Standard Development At Yorkshire Water as part of my role on the Treatment Asset Policy Team I acted as the chair of the asset standard committee and was an asset standard author and owner. The asset standards are used by the capital scheme partners to design wastewater treatment works to Yorkshire Water Specifications. The asset standards that I own included • Primary Settlement & Humus Tanks • Process Control & Automation • Liquor Balancing • Control Buildings • Storm Tanks • AMP5 Quality Schemes • Flow Monitoring & Sampling Operational Process Support In my role at Yorkshire Water I provide support to the operational schemes. This was split into to two separate areas. The first area is Shining Star Support, these are 18 of Yorkshire Water’s largest wastewater treatment works. I support the operation of five of the treatment sites, namely, Bradford Esholt, Huddersfield, Holmfirth Neiley, Halifax Copley and Harrogate South. On these sites the treatment process and energy consumption are continually monitored to optimise the efficiency of the treatment at the best potential value to both the company and the customers. The second area of process support is to all of the Non-Shining Star support to all of the treatment works in North Yorkshire. In both of these areas the support ranges from general training of the wastewater treatment operators to the resolution of complex problems that risk the consent position of the treatment works

Page 17

and could involve setting up procedures to process evaluation and recommendations for a capital scheme to resolve shortfalls in the treatment process. Project Support The project support to the asset delivery unit included support to the entire capital delivery programme ranging from pre-feasibility and the development of the Yorkshire Water “preferred” option through the optioneering process into detailed to design and from there to the construction and commissioning phases of the different projects. This included assessments of the hazards of operation, construction and commissioning. Assessment of the commissioning plans as well as checking the works prior to handover. This support has included helping to devise programme procedures, helping to resolve technical issues that contract partners may have, helping to specify the scope of projects as well as the assets that are installed and participating throughout the capital scheme process Other Process Requirements Other process requirements range in complexity. In my time at Yorkshire Water this has included

• Designing and carrying out a quality control programme to check the accuracy of the Yorkshire Water framework supplier for laboratory services. This was to check the procedures and methodology for the analysis of mercury and identified any errors in the sampling and analysis of samples. Additionally carrying out mass balance models to look at the feasibility of achieving mercury concentrations at the outfall by looking at the fate of mercury through the process and identifying the point concentrations throughout the process that would need to be achieved in order for certain discharge concentrations to be realised.

• Technical support to industrial teams to optimise the performance of industrial treatment works and meeting with clients to present the findings of investigations in order to minimise their operational costs and give them the best value.

• Outline design and costing as well as technical support to technical consultants in the preparation of feasibility reports. This particularly referred to a number of industrial clients who required growth with their businesses. Once the growth of the flow and load had been confirmed a rapid design including costing had to be developed to give an indicative cost.

Flow Compliance & Regulatory Efficiency Manager Anglian Water Services, Thorpe Wood House, Peterborough, PE3 6WT 2012- Present

Moving to Anglian Water for personal reasons I took up the challenge of Flow Compliance & Regulatory Efficiency Manger. Very shortly after joining the immediate priority was to get the business as a whole up to date with all of the wastewater flow monitoring that it was required to have in place under MCERTS. On my arrival at the company the position was 187 sites needed certifying within the calendar year with 80 of these sites needing some element of construction work. My immediate action was to put together a business plan to remediate all 8o sites and certify all 187 sites. The plan identified a capital spend of £1.28 million. Figure 9 shows some of the typical installations involved in the project

Page 18

Figure 9: Flow Meter Installations at Frampton, Islip & Marston Moretaine

The programme of works saw Anglian Water successfully complete all expired meters within a year of the start of the programme and become one of the frontier performers in the water industry in the field of MCERTS monitoring of effluent flow. All of this was achieved with the programme being under budget by £2,000. This was achieved by use of sub-contractors from Jacobs LES one of the approved local delivery partners for Anglian Water. The whole programme of works relied by developing relationships with the local delivery partners and the flow meter suppliers to take best advantage of the technologies that they had. By doing this approximately £100k was saved on the overall programme. The overall flow compliance position with Anglian Water also had to managed whilst this programme of works continued and this was done by monitoring the situation and liaising with the Environment Agency identifying treatment works that had problems with flow compliance and putting together action plans for the resolution of the problem. This required business cases to be put forward under the PR14 submissions that Anglian Water are making to OFWAT. The initial work that had been done to discover the situation in the company reaped benefits at this point in time as it was very quickly established where investment was required. In total between the base maintenance of the wastewater flow meters, the installation of new meters for potable water treatment works discharges and FFT compliance the total spend in AMP 6 pre-efficiencies resulted in three business cases totalling £22 million in AMP6 investment. As part of role within Anglian Water I am the company’s representative on the MCERTS Steering Group for Wastewater Flow. I am also a member of the Wastewater Panel at the Foundation for Water Research and I am also taking part in the UKWIR study on wastewater instrumentation, process automation & control. Since gaining a reputation in the water industry I have also been invited to join the board of directors of the Sensors for Water Interest Group and the International Water Association management committee on Instrumentation Control & Automation. Through the reputation I developed I was able to assist the State of Abu Dhabi in conjunction with Bob Cooper (Sira Certification) and Paul Wiggins (Environment Agency) to advise them on the adoption of a similar scheme to MCERTS Self-Monitoring of Flow. I have also since assisted Northern Ireland Water in the technical installation and management systems surrounding MCERTS. As part of my role as Flow Compliance Manager I developed a Flow Meter Asset Management System which has enabled me to take Anglian Water from a position where they were the worst performing companies within the UK Water Industry to one of the best.

The success in this programme of works has meant that I have taken over the operational and asset management of the entire Anglian Water Instrumentation asset base. At the current time this involves technically leading refreshing the Anglian Water system by acting as a technical mentor to a team of four maintenance technicians to record, capture and maintain the asset base of 14,500 instruments in a consistent way so that the data that the instruments can be relied upon. This is expected to feed the future operation of the Anglian Water operational business. This mirrors and expands the successful approach that was taken with regulated flow monitoring. The success of this approach has also expanded my responsibilities within the Anglian Water operational business and has meant that I have taken the lead technical and programme management of the company’s Event Duration Monitoring Programme which will see 85% coverage of event discharge monitors installed on the company’s combined storm overflows.

Career development Whilst working at Yorkshire Water I was tasked to develop my national influence and through the work that I had done in commissioning wastewater treatment works in Grontmij and knowing how to operate a treatment works manually as had to be done in the Falkland Islands I developed an interest in the instrumentation, automation & control of treatment works.

With the challenge in Yorkshire Water I developed a group on LinkedIn that discuss these subjects on daily basis. The benefits that this has given me is to wider develop my knowledge as well as my standing within the industry and it has also allowed me to write several articles on the subject and look at the wider policy surrounding instrumentation automation & control within the water industry and the direction that it is travelling in.

I have written 5 papers for the group in areas surrounding instrumentation, automation & control including the “resistance to the effective use of instrumentation,” “The Drivers, Opportunities & Barriers to Instrumentation” and “KPI’s” which looks at the information that is needed within the industry to driver the data & information management. I have also talked at a number of conferences & workshops on the subject of instrumentation, automation & control and the drivers for its use within the water industry and written a number of articles for Water Online, Water & Sewerage Journal & International Environmental Technology (more details are provided in the appendix).

Group Design Projects: Potable Water Design Project A group project based on the potable treatment works at Loftsome Bridge in Yorkshire looking at the replacement of the chemical and physical treatment processes including all of the hydraulics, pipes and civil structures and costing of the project Wastewater Design Project Feasibility study into the replacement of the wastewater treatment works at Cranfield University including

• The hydraulic design, • The addition of chemical dosing for phosphorus removal • Conversion of one of the trickling filters into an anaerobic trickling filter • Addition of a balancing tank in order to regulate flows. • Included all of the civil design and costing for the project.

Thesis Project: The Removal of Tributyltin and Permethrin from Wastewater using advanced oxidation and adsorption My thesis project at Cranfield University was sponsored by United Utilities and was on the removal of permethrin and tributyltin from wastewater using advanced oxidation processes and comparing this with adsorption onto activated carbon. The advanced oxidation processes utilised were UV photolysis, UV photolysis with hydrogen peroxide and Fenton’s Reagent. The results of the project concluded that permethrin was easily removable with UV photolysis, it being a highly photo-labile compound. However, the removal of tributyltin was more difficult and the best advanced oxidation mechanism was utilising UV photolysis with ferric iron. This was noticed when the wastewater was rich in iron achieved a higher removal with UV photolysis in deionised water. The thesis project concluded that all of the advanced oxidation methods were not economically feasible especially when compared to adsorption onto activated carbon. A copy of my thesis is available on my Box Net File on LinkedIn at the following link
