We put Queen Caroline SuDS to the test

Posted on 04 August 2016

On 29 July we put the SuDS on Queen Caroline Estate to the ultimate test by simulating a 1 in 100 extreme flooding event.

Together with the University of East London's Sustainable Research Institute we pumped 10,000 litres of water into a single swale on the Queen Caroline Estate over the course of an hour.

The swale is among several sustainable drainage (SuDS) measures we have installed around Queen Caroline Estate as part of the Climate Proofing Housing Landscapes project in Hammersmith & Fulham.

This morning's experiment aimed to test the capacity of the swale to hold and drain water in the event of flash flooding. The researchers were pleasantly surprised to find the swale had drained within around two hours, much faster than expected.

The University of East London will carry out a detailed analysis of the swale's performance as part of their wider evaluation of the project. Result's will be published in September 2016

It is hoped that data capture and analysis will help prove the efficacy of SuDS in relieving surface flooding and encourage other councils and housing providers to retrofit them more widely.
