Camley Street SuDS - St Pancras

This past Friday I spent the morning visiting bio-retention SuDS in London. The attached images are of the Camley Street retrofitted cascading rain gardens completed in March 2020. Located along an existing section of highway which runs in between the train line into Kings Cross St Pancras and the Camley Street Natural Park. 

The system has a catchment area of 1,575m² and is designed to attenuate up to 49 m³ of runoff. The rain gardens have been planted with a mixture of herbaceous grasses and perennials with some evergreen ground cover planting. However, currently, some sections are looking quite sparse.

At the lowest end section of the system, there is an overflow connection to the main sewage system.

Overall, the project created 142m² of additional green infrastructure. Disconnecting 1,537m² of ground surface area from the River Thames / Beckton sewage catchment and overall the project cost £223,000.
