About the Drainage and wastewater management plan
Why develop a DWMP
We are publishing our drainage and wastewater management plan (DWMP) to show how we are addressing pressures on our drainage and wastewater systems for current and future risks.
Climate change, population growth, increases in awareness of storm overflows, tightening environmental standards and changes in customer behaviours and expectations are putting increased pressures on the water sector.
We have a privileged status as a provider of essential sewerage service to around three million customers and to protect the highly sensitive environment within the Wessex area.
We are proud of our historical industry leading performance for customers, our communities and the environment, and we believe we should be an exemplar to the industry of the future, trusted to leave the environment in a better condition for future generations, while keeping our services affordable and satisfying for customers.
What is a DWMP
The DWMP framework was developed by the water industry and key stakeholders to provide a consistent approach across water companies for long-term sewerage planning.
It identifies how we will extend, improve and maintain a robust and resilient drainage and wastewater system in light of the current pressures on the industry.
Our strategic plan sets out the required level of investment required to achieve our outcomes, such as having an effective sewerage system and high-quality water.
Working with partners
Throughout the development of the DWMP, we have been engaging with numerous stakeholders, including customers, regulators (Environment Agency and Ofwat), catchment partners and flood risk management authorities (RMAs), such as the Lead Local Flood Authorities (LLFA).
Engagement with other RMAs is essential for DWMPs because drainage responsibilities are complex. We need to continue working in partnership with our stakeholders to find opportunities for the co-creation of water solutions to achieve efficiencies in delivering our outcomes.
