What are DWMPs?

DWMPs are long-term plans – spanning 25 years or more – that set out the investments needed to make wastewater and drainage systems fit for today and the future. It’s about planning for future climates and population, whilst reducing storm overflows, flooding and pollution for the benefit of customers, communities and businesses, and to protect and improve the water environment.

DWMPs – the story so far

We are one of 10 water companies across England and Wales that have committed to produce a DWMP for the first time by the end of March 2023. These Plans build upon previous long-term planning by water companies, such as Drainage Area Plans and Drainage Strategies.

Defra, Ofwat, the Environment Agency and others have developed a national DWMP framework to guide the development of DWMP.

Water companies are asked to produce one regional DWMP for their operating area based on the plans for each River Basin Catchment and the drainage and wastewater systems within these. The map below shows the 11 river basin catchments across our operating region.
