22045 Hamburg-JenfeldHAMBURG WATER Cycle®, an urban quarter with 835 residential units, 630 of them in new buildings, and commercial space for around 2000 residents is being built on 35 ha of the former Lettow-Vorbeck barracks. Project costs: approx. 250 million euros. The most far-reaching project of a decentralised water supply and disposal system currently in Europe: vacuum toilets, biogas production and waste water separation (HAMBURG WATER Cycle®). The biogas produced will be used to generate heat and electricity for the new district in a climate-neutral manner in the district's own combined heat and power plant. The project will thus enable climate-neutral living and sustainable drainage.
