Sustainable drainage on a roadside

Rainwater Management

We’re redesigning how rainwater is managed across the North West – using nature and smart engineering to reshape places and strengthen resilience.​ Together with communities and local partners, we’re creating greener streets, richer habitats and inspiring spaces for people to live, work and explore.

What is Rainwater Management?

Our flagship Rainwater Management Programme is delivering large‑scale, nature‑based solutions across towns, cities and catchments - creating healthier, climate‑ready places and reducing pressure on our wastewater network.

We’re working with local authorities, community organisations, developers and regional partners to bring projects to life, aligning Rainwater Management with broader ambitions for growth, net zero, active travel and placemaking.​

By integrating features such as raingardens, permeable surfaces, tree pits and sustainable drainage into streets, schools, business districts and public spaces, we can:

  • reduce pressure on the combined sewer system
  • lower flood and spill risks
  • improve climate resilience
  • enhance biodiversity and green space
  • create more attractive, accessible and future‑ready environments

How we manage rain

Capturing rainwater

Capture 

We capture rain to stop downhill flooding through Natural Flood Management schemes. ​

Rainwater

Attenuate 

We use rainwater management solutions to slow the flow of water entering sewers.​

Disconnecting rainwater

Disconnect

We disconnect surface water​ from our combined sewer system and direct it to​ rivers and canals.​

Garden planter

Reuse 

We help communities use rainwater for everyday tasks like watering plants and cleaning cars.​
