Climate actions
Use of rainwater
Objective
Collect rainwater.Description
A catchment for rainwater is advised per house/block of apartments (individual rainwater tanks). Usually, rainwater can be used where drinking water is not required, like for toilets, washing machines and for external uses like for car washing and watering.
Expected results
Buffering of rainwater on the level of individual plots to prevent flooding during more severe rainwater events (impact on city quarter level, city level and regional level); buffering of rainwater as reserve for periods of drought and sustainable water use; reduction of drinking water consumption.Result indicators
Volume of collected water [m³]Volume of saved drinking water [m³]
