Northumbrian Water is committed to producing Drainage and Wastewater Management Plans (DWMP) which will provide a basis for long-term planning of drainage and wastewater services.

These plans are based upon guidance from Water UK and are being produced industry-wide.

Why do we need DWMP

Drainage and Wastewater Management Plans (DWMP) give us a starting point for long-term planning of drainage and wastewater services.


These plans are based on guidance from Water UK and are being produced across the industry.


The DWMP will show how we will:

  • support economic growth
  • support resilient communities, and
  • protect and enhance the environment.

We'll collaborate with others outside of Northumbrian Water to ensure the DWMP is of benefit to all of our stakeholders and customers.

What it means for you

The DWMP sees us analyse sewer performance across our region and highlight where future work will be needed.


We focus on three key areas:

  • flooding
  • environmental, and
  • sewage treatment. 

We'll look at these issues so we can make sure Northumbrian Water’s next regulatory business plan submission take those issues into account.


To get the best outcomes for everyone in our region, we'll work with customers and any organisations who have an interest, including stakeholders with an interest in planning, development, risk management and the environment. 

How can customers get involved?

Making sure you're able to let us know your thoughts is really important to us.


We've already carried out some customer research to help us understand the issues which are important to our customers.


If you want to have the chance to take part in upcoming feedback sessions, there will be more opportunities coming soon. Make sure you let us know you want to take part by emailing 

1000's of hours of analysis

How do we plan for the future? Well, we don't have a crystal ball, but we do have the next best thing - technology!


We used computer models of the drainage network across our region. We looked at how the network behaves now, and then introduced proposed developments, as well as climate change, into the model, to see what would happen.


This work has involved a team of specialist hydraulic modellers based in the UK and India and over 100,000 hours of analysis.
