Drain London

The Drain London partnership is focused on mitigating the risk from surface water flooding and increasing the use of sustainable drainage

  • By Jennifer Sibley

We have been involved in the Drain London partnership since its inception, along with London’s 33 councils, the Environment Agency, Thames Water and the Greater London Authority (GLA). Rain garden reducing surface water run off.

Its purpose

The partnership was set up to enable local authorities in the capital to work together to better understand surface water flood risk and build their capacity to manage their flooding risks. Its initial focus was to establish ownership of London’s drainage assets, assess their condition and secure a better understanding of the risk from surface water flooding, so that boroughs and the GLA can manage and improve drainage assets and mitigate the risk from this type of flooding.

Its work so far

The partnership has so far delivered surface water flood risk maps and management plans for each Lead Local Flood Authority (LLFA), as well as detailed studies into flood risk areas and the vulnerability of critical infrastructure. The partnership has also showed how surface water flood risk can be managed or mitigated through a series of demonstration projects. The partnership's future focus is how sustainable drainage techniques can be used to address flood risk in London. 

To address this, Drain London has published its London Sustainable Drainage Action Plan. London Councils contributed to the creation of the Action Plan and are proud to support it.
