Underground water retention basin
An underground water retention basin can manage excess stormwater runoff in an urban setting where there is insufficient space on the site to filter it. The underground water retention basin improves the water management of the Gavoglio Park for green area irrigation. It receives water from an existing spring and from some drainage pipes.
The tank must be positioned on a flat stable surface. Manholes must be properly embedded on the pavement. A pump station in the tank inlet and outlet pipes provide water to the irrigation system.
Potential for replication and upscaling
The increasingly frequent occurrence of intense rainfall events that alternate with periods of drought makes it useful to collect and recycle rainwater systems. This can reduce the run-off phenomenon and the use of drinking water for non-human uses. There are many different types of underground water retention basins available.
