Aim:

„ Good safe drinking water that has the trust of consumers“

Proposal:

WSP-Conception of WHOSeptember 2004

Activities in Austria

The ÖVGW (Austrian Association for Gas and Water) prepared and published Guideline W88 (Manual for the introduction of a simple water safety plan) – May 2008

Designed for small drinking water facilities Some Austrian Water Suppliers have employed WSP Translation of the Guideline W88 (English version) during the

SHARP-Project (PP8 – Germany, PP7 – UK)

W88 - General Informations Drinking water is our most important necessity –

high demands on water supply services regarding hygiene, security and protection of ressources

The operator is in charge for a correct operation of a water supply installation and for hygienic drinking water.

The high quality of drinking water only can be ensured by preventive quality assurance and permanent quality control. physical / chemical/ microbiological condition, technical eminent parameters have to be detected early and - if necessary - avoided.

W88 - General Informations this guideline offers a manual and support for the

implementation of a product- and process-orientated quality-management-system, with which regularily all processes of a water supply service can be checked and improved.

Hazard-identification and risk evaluation are the first steps necessary for a management system. This guideline uses, the actual WHO recommendations, many principles and concepts of the HACCP – method (Hazardous Analysis and Critical Control Point), which is implemented in the rest of the food industry.

W88 - Areas of Application• This guideline is a master profile for the organisation and

systematisation of drinking water – related management practises. The guideline defines the terms hazard identification and risk evaluation, which mark the starting point for setting up a system management. This guideline particularly applies to small drinking water facilities.

• With clear work instruction in eight steps - illustrated with examples and supplemented with sample forms – this guideline is a reference for setting up a system for self-checking.

Preparing annual assessment on water, facilities, processes and proposals and implementation of the organization and improvement

Organisation, responsibilities and expertise

Step 1:

Description of organization of water supply and tasksand expertise of staff (job description)

Order 1:

Create an organizational description of the water supply company.(Organizational chart with the supervisor of the manager) and job description and qualifications of the manager and their employees

Inventory of water supply

Step 2:

Updating or writing of the inventory of water supply system

Order 2:

Update or create the map of project area and the facility scheme and create a list of main facilities. They also collect the current data base for the entire water supply

Assessment of water supply

Step 3:

Looking for/Search and assessment of potential risks to water supply and listing of critical points

Order 3:Search all potential hazards in the whole water supply by using the checklist “hazards” Evaluate the potential hazards and document the detected critical points in the form and in the general plans by using the form ”risk assessments”

Catchment area and Protected ZoneHazard

1.4 Liquid fertilizer tank: risk of leakage 1.5 Dunghill: danger of seepage 3.1 Fertilizer: into the groundwater 3.2 Pesticides: into the groundwater 4.1 Street: risk from leaking oil, petrol in an accident 5.1 Brook: Risk of polluted surface water 5.2 Brook: Risk of Flooding 6.5 Contaminated sites, landfills risk of leakage

Requirements for a collection tank for spring waterRequirements

7.0 Shaft height at least 30 cm above ground level7.1 Manhole cover: lockable, rainwater proof, ventilation7.2 Entrance below the water table7.3 tight structure7.3 Inflow is located 20 cm above the highest water level 7.3 corrosion-resistant pipes, water pressure-resistant pipe penetration7.4 Drain / overflow frog flap, min. DN 100, siphon7.5 Supply line with water meter and gate valve

Elimination of hazards at critical points

Step 4:

Implementation of temporary measures to eliminate or reduce hazards at critical points

Order 4:Eliminate all eliminable hazards at reasonable cost, using the standard form "Elimination of dangers" to the final success control. Enter in the standard form “action plan” long-term and costly measures with priority and time.

Reduction of hazards at critical points by maintenance

Step 5:

Updating or creation of instructions for maintenance

Order 5:

Update for the critical points of the existing maintenance instructions or create new maintenance instructions

Risk managements at critical points through controls

Step 6:

Preparation of instructions for control of critical points

Order 6:

Create for all remaining critical points, a control point directive "control point".

Practical implementation of the instructionsStep 7:

Follow instructions in everyday life and reporting and evaluation of results

Order 7:Instruct the responsible staff and make sure that all maintenance instructions and all control point instructions are strictly observed and record the relevant activities and findings in everyday life. Initiate if required by error message, the necessary corrective action

Annual evaluation of water supplyStep 8:

Preparation of annual evaluation of water, plants, processes and organization and propose and implement of improvements

Order 8:Create a comprehensive annual assessment of water quality and the influence of the systems, processes and quality management organization. You should also assess the accuracy and completeness of the instructions. Create a short written report and initiate improvements if needed

Conclusions WSP is a general quality management tool for drinking water

suppliers in order to safe drinking water quality. Hazard-identification and risk evaluation on the principles of

the HACCP – conception (Hazard Analysis and Critical Control Point)

This guideline worked out by the Austrian Association for Gas and Water (OVGW) particularly applies to small drinking water facilities in Austria.

The WSP guidance can also be useful for drinking water facilities all over Europe
