3. Moselle Brook SuDS Projects

Themes: Water quality; Biodiversity; Getting people and communities engaged


  • Reduce the frequency and severity of pollution
  • Increase surface water management at source
  • Improve knowledge and understanding of the catchment
  • Improve awareness of the impact of behaviour on the water environment

Project description

Greenstreets is a partnership project that aims to demonstrate how measures to address road pollution and flooding in a local area can be identified, designed and installed and maintained with community participation.

As part of the Love the Lea campaign Thames21 is working with the London Borough of Haringey and the Environment Agency to deliver an exciting new project.  Greenstreets is a partnership project that aims to show how river pollution can be cut and surface water flooding risk reduced with community participation.
The River Moselle flows through Haringey from Queens Wood in Muswell Hill to Markfield Park in South Tottenham where it joins the Lea. From Queens Wood the Moselle is hidden as it passes through Hornsey, Wood Green and Crouch End in a pipe underground. We don’t see the river, so we don’t see it being polluted by misconnected plumbing from properties on it’s route underground and surface water runoff.  We know there are misconnected pipes feeding the Moselle, it’s evidenced by the absence of life where the river is visible and by the volume of sewage fungus growing on the plants.

The London Borough of Haringey has identified 9 Critical Drainage Areas (CDA) and we’ll be focusing on Drainage Area 55; this covers most of Hornsey, Muswell Hill and Crouch End wards and the projected flow of the Moselle on it’s underground journey. These drainage areas have been specially mapped to project the risk of flooding from surface water in a very severe rain storm; they show where water is likely to form ponds and the flow pathways.

Greenstreets seeks to raise awareness to residents in Drainage Area 55 about:

  • The River Moselle
  • Pollution from misconnected plumbing and road run off
  • Flood risk and alleviation measures
  • Sustainable Drainage Systems (SuDS) and hopes to implement two retrofit SuDS
