Driving capital efficiency through PAS 55

In 2008, Dwr Cymra Welsh Water (DCWW) recognised that PAS 55 certification would not only bring key benefits to AMP5"s "business as usual" activities and beyond, but would also support the PR09 process. Achievmg PAS 55 certification in March 2009, DCWW has been operatmg under the new accredited framework for almost 3 years. As part of the "Plan, Do, Check and Act" cycle, in January 2011 DCWW decided to undertake an assessment of how lessons learnt from the implementation of PAS 55 could drive further efficiencies. EC Harris was appointed to undertake a pilot study for the water treatment works programme and they identified around 10% of additional savings to be realised. This joint paper provides a detailed case study demonstrating how PAS 55 principles can deliver tangible improvements for an asset intensive utility company.
