Heavy precipitation results in high pressure on the urban water system. This leads to pluvial flooding and overflowing of the sewer system into the surface water. In order the mitigate the impact of these events, separate sewer systems and water storage facilities are implemented in cities. Surplus water overflowing from surface water or sewer system can be stored in a reservoir for a period of time and later slowly discharged back into the water system via pumping or infiltration. In most cases, the water is not harvested for reuse. However, rainwater has a high potential for reuse. Evaporation and aquathermia are two types of the use of water in systems to cool and heat buildings. Both offer a potential application for the reuse of harvested rainwater. This research paper aims to illustrate the position of rainwater storage and harvesting in the urban water system and investigates the possibility of reusing the harvested rainwater in systems cooling or heating buildings.

In the final project, the findings are implemented in a design for a new theatre in Gouda. The design aims to create a more open, attractive and efficient theatre that will attract a wide variety of audiences. All while dealing with the challenges of the location: subsidence, water nuisance and urban heating. The new building gives space to the theatre and the neighboring community centre. A large underground storage, roof ponds and rain-curtain facades all add to a resilient and characteristic new theatre building and a comfortable indoor and outdoor climate.
