The Durdham Down Combined Main (DDCM) is a 10.2-kilometre (6.3-mile) potable water main running from Harry Stoke in the North of Bristol to Victoria Reservoir, Clifton. This project is part of a £22 million investment by Bristol Water to increase resilience and provide for growth in North Bristol.
Bristol is a city in south-west England and home to more than 400,000 people. The 700mm diameter pipeline is routed into the heart of Bristol, and with this came a number of key constraints. A major constraint and theme running through the project has been stakeholder engagement, recognised as one of the most important features in getting this project completed successfully.
