USING RESEARCH TO INFORM INTEGRATED CATCHMENT MANAGEMENT
A regional business perspective
What is YW business perspective?Increasing costs treatment opex capex
What are the water quality trends?
• Significant challenges due to increasing colour
• Significant upward trends in nitrate concentrations aquifers
• Rising nitrate levels in rivers
• Number of catchments risk failing pesticide standard
Conventional Response to risk of failure - Blend - Treat - Abandon
Many land uses/other factors influence WQ
• Regulation is standard driven
• Tended to result in engineering solutions
• But times are a changing…. Water safety plans WFD Polluter pays
Protected drinking water statusClimate change

OFWAT sustainability dutySDS – longer term view
Water Framework Directive
The overriding aim of Article 7:-
“ensure the necessary protection for the bodies of water
identified with the aim of avoiding deterioration in their quality in
order to reduce the level of purification treatment required in the
production of drinking water”
• Not unlimited protection• Significant improvement• Only applies to anthropogenic parameters
Water companies may see opportunities to address drinking water issues by encouraging changes to land management in the catchments providing raw water for public water supply.
If,
• the company owns the land;
• the land contributes to the achievement of the aims of the regulated business;
• the investment relates to changes in land management practice to meet a defined legal requirement; and
• the proposal is both cost effective compared with other options and is costbeneficial
OFWAT’s view on Catchment Solutions
Our Customers' Voice Our external challenge & YW 'headline' position Our objective Our priority Our aspirations to 2035 Our direction
Customers want a continuousuninterrupted water supply
Children and young people want water for future generations
Customers want high qualitydrinking water
Stakeholders want protection of Drinking Water quality
Children and young people want a water supply that is safe to drink
Customers want improving river water quality
Stakeholders want environmental considerations to be addressed
Regulatory regime (Economic)• RPI-X methodlogy works well• Increased 'carrot & stick' incentives required
Charging base and metering• Yorkshire is not water stressed• Metering based on customer choice - demand led• Innovation required to drive lower unit cost of metering
Rate of return and financing• Regulatory risk managed through a transparent & consistent approach• Setting returns in line with an appropriate cost of capital
Competition and mergers• Current regulatory regime works well• Retail competition increases risks• Support competition "for the market"
Striking the right balanceStrategic Direction Statement 2010-2035
• Innovate water resource management• Halve leakage• Develop real time Grid management• Expand the Grid in a measured way• Research variable and dynamic abstraction licences
Providing a customer experience
second to none
Delivering the very best drinking water quality
Zero drinking water quality failures
Zero interruptions
Our principle for all assets is ‘invisible operations - visible service’
• Improve service at reduced costs• Increase maintenance for water distribution and sewerage assets• Work towards national service standard for interruptions • Promote a strong, innovative, vibrant supply chain• Drive research and innovation in service delivery.
Financial institutions requirereturns on investment
New environmental obligations• Investment should demonstrate clear benefits & be justified by sound environmental science• A need to resolve conflict between obligations and CO2
• Measured & phased approach required
Delivering attractive returns for investors
and lenders over the long term
Have no water restrictions
Customers want excellent all-round customer service
Ensuring there is never a need for water
supply restrictions
A strong ENVIRONMENTAL
focus
A customerSERVICE
experiencesecond to none
Going beyond environmental
compliance
Customers want to prevent sewer internal flooding to homes
Children and young people want tosee climate change being tackled
AttractiveRETURNS
for investors
Stopping our sewers flooding homes and businesses
Attract investors through our out-performance
Zero pollution incidents
Zero flooding of homes as a result of failure of our assets
Stakeholders want to see reduced leakage
• Understand our sewerage network in real time• Build capability to forecast and manage environmental improvements supported by 'next generation' of hydraulic modelling• Continue to target risk based investment efficiently
• Maintain an efficient financial structure by being flexible and responsive to market conditions• Attract new 'low cost' investment to finance service and environmental improvements• Meet the needs of exisiting and new financial stakeholders• Differentiate ourselves through operational and capital out-performance
Providing tailored services
for customers
Provide tailored services and greater choice
• Listen to our customers and provide a greater say in products and services• Develop innovative communication channels • Explore additional valued added services• Expand real time provision of data for Business customers' use
Provide the lowest possible prices• Continue to be lean, fit and customer focused through our core services• Drive innovation and out-performance to deliver lowest possible prices
• Provide protection against flooding for 1 in 30 year events• Work towards National standards to respond to climate change• Develop 'next generation' hydraulic modelling• Increase sewerage network maintenance investment
• Continuously improve water supply resilience• Use risk based water safety plans• Develop catchment management• Further reduce distribution discolouration• Monitor and operate the network in real time
Reducing leakage significantly
Halve existing levels of leakage .
• Halve exisiting leakage levels and contribute to a healthy water resource balance• Drive our carbon footprint down • Promote emerging technologies in detection and repair
Climate change• Investment only where the benefits exceed the carbon impact• Understand the impacts• Requires new legislative approaches• Mitigation and adaptation
Mitigating our carbon footprint & adapting
to climate change
Meet greenhouse gas emission targets as set by Government.
• Mitigate our carbon footprint by driving new carbon initiatives• Work with Government to reduce the impact of legislation• Undertake strategic research to enable the adaption of our assets to climate change
Affordability for customers• Driving for lowest possible price levels• Challenge environmental pressures toallow water supply and flooding investment• Social tariffs should be addressed by Government
The lowest possible PRICES
for customersCustomers want value for money
Providing the lowest possible prices
Stakeholders want to see improved maintenance of our assets
e.g. pipes and sewers.World class ASSET management and great PEOPLE • Recruit and develop technical and business leaders
• Inspire everyone to achieve our Vision
Strategic Direction Statement
Delivering the very best drinking water quality
Zero drinking water quality failures
• Continuously improve water supply resilience• Use risk based water safety plans• Develop catchment management• Further reduce distribution discolouration• Monitor and operate the network in real time

Agricultural Land Management Strategy R & D
Three integrated projects to assess:
– Agricultural measures to improve WQ
– Targeting need for agricultural measures
– Assessing potential improvement
– Influencing for change
– Impact on agriculture (economic & social)
Catchment Sensitive Farming
• Ingbirchworth Catchment (near Penistone)
• Nitrate Vulnerable Zone compliant
• Nutrient sampling – water & soils
• Nutrient modelling
• Demonstration days and 121 Farm Advice
Comes down to one simple question……
…….does catchment management work!

Activities undertaken to reduce pesticides
• Training & Awareness sessions (Calibration Cards etc.)
• Education visits to adjacent WTW to explain processes
• Amnesty on expired products
• Identifying key players in the catchment
• Helping Agronomists & Contract Sprayers understand the issues – their increased use of wetters/ alternative products
• Closer working with tenants to better understand their pesticide usage and crop needs
• Development of Crop Management Plans
• Encourage alternative crops with lesser pesticide needs
