DWMP explained

Our DWMP aims to keep your toilets flushing, reduce the risk of homes flooding and protect rivers and wetlands, while keeping your water bill affordable for the next 25 years and beyond.

It’s the first time a long-term plan has been co-created to deliver a resilient and sustainable wastewater service. We've engaged and worked with around 2,000 customers and stakeholders to develop our plan.

The DWMP sets out the risks and pressures for our drainage and wastewater service that include:

  • A growing population 
  • Climate change – extreme weather affects everything from the size of our pipes to the water levels of our local rivers
  • Protecting and enhancing our environment
  • Loss of green spaces – leaving rainwater without anywhere to drain
  • Keeping customer bills affordable

Our DWMP details the actions needed to tackle these challenges and the risks they create, such as property flooding and storm overflow discharges. This is a shared plan that has partnership-working at its core. Find out more about how we created our DWMP together.

Five stage development process

The DWMP framework includes a five-stage development process. We extended this process to include the public consultation feedback on our draft plan last year, as well as regulatory updates. 

We’ll update our DWMP every five years to make sure the scope of our work keeps up with the most current challenges we're facing.
