Smart Rainwater Buffer XXL : concept for the UT campus

To tackle unfortunate events such as heavy rainfall and droughts, a solution is presented which offers a large water storage capacity and makes it possible to harvest and store rainfall. The solution comes in the form of a large volume Smart Rainwater Buffer (a.k.a. SRB XXL); a large silo tank which collects rainwater from nearby rooftops and is able to self-regulate the stored water content in order to be most efficient depending on the current or near-future weather conditions and is located on the campus-terrain of the University of Twente at the “Sport-Centre” building. In this bachelor thesis, research, stakeholder interview-sessions and the Creative Technology Design Process are performed to create a concept for the SRB-XXL which satisfies the condition of being both a rainwater buffer as well as a harvester. Furthermore, a user interface dashboard design is created with the purpose of providing the user of the SRB-XXL with information regarding the water level, status conditions and future precipitation events, as well as allow the user to perform system-control commands. Also, the rainwater router is realized to direct the overflow water in case the tank reaches full water capacity and to minimize altering the storage tank’s base composition.
