RPS Contract with Dwr Cymru Welsh Water (DCWW) Extended For Five Years

Posted: Monday 11th October 2010

The RPS Contract as Dwr Cymru’s Strategic Leakage Control Partner has been extended for a further five years. The contract started in 2005 for an initial five year period and has now been extended to 2015 with an option for a further five year extension.

The contract covers the whole of DCWW’s area and involves assisting and advising DCWW on:

· Audit monitoring and reporting of leakage levels and all associated data for leakage control activities.

· Improving base data quality and information

· The strategic direction of Dwr Cymru’s leakage control initiatives.

The contract involves some 85 staff, the main activities being:

· Regional Strategy - Advise and assist Water Demand Manager, Leakage Performance Indicators, PCC Monitoring , Top Down–Bottom Up Balancing/Reporting , Economic Levels of Leakage,

· Reporting - Annual Ofwat Returns , Water Balance Gap, Validation and Reporting, Daily Distribution Input and Demand figures,

· Area Work - DMA Targeting and Auditing, Leak Detection Field Work, Service Reservoir Monitoring, Zone and Company Hour to Day Factor,

· Projects - Marginal Cost of Water, Household and Non-Household Night Use Monitoring , Trunk Main Surveys , Meter Verification and Key Meter Replacement , Water Treatment Works Balancing.

The contract also requires a capability to innovate, develop and successfully implement new systems. As part of activities to meet this requirement RPS has, in conjunction with Technolog and Dwr Cymru, developed a new innovation in flow monitoring called the Accuflow™ acoustic flow meter. This device enables conventional sluice gated valves on the distribution network to act as metering points. The device was awarded the “Most Innovative New Technology of the Year” at the Water Industry Achievement Awards held in May 2010. Other RPS system developments which are used on the DCWW contract are:

· LMARS (Leakage Monitoring and Reporting System) which is used to determine optimum leakage levels and to compile leakage reports;

· MAVIS (Metering Audit Verification Integrated System) used in the meter verification process and also to rank meter replacement schemes ;

· SALT++ (Strategic Analysis of Leakage Targets + Supply-Demand Least Cost Planning) used to calculate the short run economic level of leakage and supply/demand balancing.

During the initial five year period of the contract RPS helped Dwr Cymru reduce leakage by 31 Ml/d (16%) and meet its annual Ofwat leakage target each year.

RPS Regional Director for Wales, Arthur Arscott said “We have acknowledged all the good work our staff have done over the initial contract period as, without it, we would not have been in a position to have the contract extended. The extension demonstrates DCWW’s confidence that RPS can continue to deliver a market-leading service in difficult economic times. We are positive about achieving some very challenging efficiency targets over the next five years.”

Water Demand Manager for DCWW, Gordon Hall said “We are pleased to have extended our contract with RPS and are looking forward to another successful five years of working together. The recent severe winter, followed by very dry spring and early summer, have again highlighted the importance of having a robust leakage strategy. The current economic climate does present a very challenging future but I am sure that our continuing partnership will be up to the challenge.”
