Flood management projects
Astley House
Astley House is an estate on Rowcross Street (SE1 5HU) where a Sustainable Drainage Systems (SuDS) scheme will be delivered in Spring/Summer 2024. This will address pressure on the local sewer system, which can cause flooding during storms.
The solution
All roof drainpipes on the southeastern side of the Astley House building will connect to a new underground pipe. This pipe will transport rainwater into an area of lower ground in the open green space next to Astley House which will act as a basin. During heavy rainfall, the basin will store rainwater temporarily and allow it to slowly be released into the sewer system.
The results
Storing rainwater in the basin will mean rainwater enters the sewer more slowly. This will reduce pressure on the local sewer system and lower the risk of flooding during heavy rainfall.
The project will also help the environment by filtering polluting particles.
New planting in this area will also improve the biodiversity of the housing estate and provide better outdoor space for residents.
