Quick Summary

East London's Redbridge Council is enhancing its flood defences with new Hydrorock installations along High Road in Seven Kings, Claybury Broadway in Clayhall, and Tomswood Hill in Barkingside at a cost of £11 million. The council aims to mitigate flood risks identified from past incidents by deploying this underground system that absorbs rainwater during heavy storms. Councillor Jo Blackman highlighted the need for these measures due to increasing extreme weather events. The borough’s network can now hold up to 2.2 million litres of storm water, with recent additions capable of temporarily storing around 426,000 litres each.

Story summary

An east London council has expanded its flood defences across the borough in response to growing threats from extreme weather. The £11 million plan includes installing Hydrorock, an underground system that acts like a sponge, at three sites: High Road in Seven Kings, Claybury Broadway in Clayhall, and Tomswood Hill in Barkingside. Councillor Jo Blackman highlighted the need to "strengthen our flood defences" as extreme weather becomes more common due to climate change. Hydrorock, developed in the Netherlands, absorbs rainwater during heavy downpours and releases it slowly into the sewer network, preventing sewers from being overwhelmed and reducing the risk of flooding. In addition to underground works, sections of road were resurfaced with permeable paving to help absorb rainwater further.
