Dwr Cymru Welsh Water (DCWW) is the sixth largest of ten regulated water and sewerage companies in England and Wales. It provides an essential public service to more than three million customers. Managed by Glas Cymru since 2001, DCWW is a not-for-profit company and has the sole purpose of delivering a high-quality, reliable, drinking water and sewerage service to its customers.
With the escalating cost of energy, the need to comply with the Carbon Reduction Commitment Energy Efficiency Scheme and as part of its sustainability strategy, DCWW invested £70 million in a programme to construct advanced digestion plants at Cardiff and Afan, which will produce biogas that can be used to generate green power for the sites.
Contracts for the construction were awarded in June 2009 and it was necessary to complete the work by March 2011. By the application of innovative partnering and supply chain management, the projects were delivered six months early and, since October 2010, renewable power generation has exceeded expectations. More than 3,600 MWh of renewable electricity was produced in the first 6 months of operation.
DCWW worked closely with its Capital Delivery Partners, Imtech and Morgan Sindall, and supply chain partners to measure its carbon footprint, set improvement targets and identify innovations to maximise energy efficiency and reduce emissions.
These operations will process 50,000 tonnes of dry solids per year using thermal hydrolysis plants and new digesters. High-efficiency combined heat and power units will save about 50 GWh/year of energy and reduce CO2 emissions by over 50,500 tonnes. Overall, this programme will reduce DCWW’s operational carbon footprint by 15%, the most significant contribution to its reduction target of 25% by 2015, and give annual operational cost savings of £7 million.
