Collective RWH from roofs and paved surfaces. Rainwater is treated to drinking water quality. Overflow to water square and infiltration ponds. | Most of the DW is produced locally from RWH. The rest (ca. 10%) is supplied by the centralised DW system. This source is surface water in Germany. | GW is locally treated in a vertical aerated helophytefilter. Research will be done to test if it is of good quality to use it as HW for a shared laundry. |

BW is separatly collected and digested in a neighbourhood UASB-reactor, nutrient recovery as struvite are currently being developed. | FW is added to the BW vacuum sewage after which it is digested in the UASB-reactor. | Biogas from the digestor is reused for heating the digestor. Energy is produced using a turbine at a nearby location where pressure reduction is necessary in the centralised system. |
