Surface Water Management Programme

We’re working in one of the most densely populated and built-up regions in the UK, which places a lot of pressure on drainage. Without action, population growth, urban creep and climate change would increase the likelihood of sewer flooding and pollution.

We’ve historically focussed on engineering solutions, but we’re shifting to sustainable drainage systems (SuDS) which replicate the drainage processes provided by the natural environment.

This approach can help to: 

  • manage the quantity or rate of runoff of surface water (and so improve flooding resilience, as well as reducing the need for overflows),
  • improve the quality of surface water run-off (and so reduce the risk of pollution),
  • improve the amenity of public spaces as well as wider community benefits,
  • help improve biodiversity and the customers’ experience of their local environment.

Call for projects

We're now inviting eligible applicants to apply for funding of surface water management projects. We are planning to allocate £1.5m in this round, with a further project call to follow later this year.

The Surface Water Management Programme (SWMP) funds will cover design and construction costs of projects that disconnect or attenuate surface water flows from Thames Water sewers. Our sewers include surface water, combined and foul sewers. 

How to apply

Please complete the application form, including required supporting information, and email it to us at swmp.applications@thameswater.co.uk.

The funding application will need to be signed by a person of a suitable authority within the organisation.  Your supporting information may be in draft form at application stage, in which case project approval will be subject to confirmation prior to signature of the funding agreement. 

The deadline for submitting funding applications is Tuesday 31 August 2021. 

We’ll provide feedback to applicants by the end of October 2021 at the latest.

If you’re interested in working with us, but your project timescales don’t fit with the specific parameters of this call for projects, please email us.
