Creating resilient wastewater catchments

We’re planning ahead to manage wastewater and drainage issues so your local area is ready for the impact of climate change and population growth in the future.

We've created our Water Resources Management Plan (WRMP)  to protect your future water supply. And we’re now creating our first Drainage and Wastewater Management Plan (DWMP) to make sure we can provide a reliable and affordable service for years to come.

Our Drainage and Wastewater Management Plan

A DWMP is a long-term (25 year or more) costed plan that sets out the future risks and pressures on our drainage and wastewater systems and identifies the actions required to manage them.

Responsibility for drainage in England lies across several different organisations, including the Environment Agency, local authorities the Highways Agency – and us. This means it’s critical our DWMP is founded on partnership-working, with all the different agencies actively involved and contributing to the development of the plan.

Find out more about the wastewater region we cover.

The DWMP will make sure we can continue delivering our services reliably and sustainably, while also having a positive impact on customers, communities, and environment.

Since early 2019, we’ve been working hard to develop our DWMP with our stakeholders and customers to create a shared plan that meets the requirements of the majority.

Our DWMP needs to be ready for consultation in summer 2022. Then the activities identified in the first five years of the plan can be included in the 2025-2030 business plan, which will be consulted on and reviewed by our regulator in 2023-2024.

How we're creating the DWMP

In 2018, Water UK collaborated with water companies across the UK, plus the Department for Environment, Food & Rural Affairs (Defra); the Welsh Government; Ofwat; the Environment Agency; Natural Resources Wales; the Consumer Council for Water; ADEPT; and Blueprint for Water, to create a DWMP framework.

We’re working through the following five stages of the framework:

  1. Scope and context: An overview of our drainage and wastewater region, plus the drivers and objectives that shape the DWMP
  2. Initial catchment screening: An overview of our region’s results from the industry-wide catchment vulnerability screening against 17 different risk indicators
  3. Catchment risk analysis: A more detailed assessment of our catchments, which will help us understand the risks they face and identify opportunities for solutions
  4. Developing interventions: A list of solutions we and/or our partners have considered and their feasibility
  5. Programme update: An up-to-date, high-level view of our plan and where we are

Next steps

Once we have more details on the options from Atkins we’ll share this via our portal.

Everyone will get a chance to have their say in July 2022, when we’ll consult on the DWMP, and then again in 2023, when we consult on our next 5-year Business Plan alongside other water companies.

How to get involved

If you’re a partner

This is a collaborative plan, and we rely on your knowledge and expertise of the local wastewater and drainage system and the future pressures on it. We’ve uploaded all the relevant data about our plan so far to this restricted access practitioner portal so we can work together on it. If you want to collaborate on our shared DWMP or get access to the portal, please email us at

If you’re a customer

We’re using customer input from previous reports, current incident data and new focus groups and online surveys to shape our plans, and in 2022 you’ll have the opportunity to comment on the DWMP through public consultation.

Please use this page and the customer portal to keep up to date with the progress of our plan and for updates on the public consultation in July 2022.
