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.
