Our partner for asset management and leak repair: Hamburg Wasser


Hamburg Wasser is Germany's largest publicly owned water supply and wastewater disposal company. Non Revenue Water (NRW) is at only 3.6%. Consulaqua Hamburg GmbH, a 100% subsidiary of Hamburg Wasser, offers sustainable and affordable services in water loss reduction which are based on the latest technical developments, extensive O&M, hydraulic know-how and are adapted to particular requirements of clients and partners worldwide.

The overall runtime of leaks consists of awareness, location and repair times (ALR – see Figure 3.2 below). Long leakage runtimes will generate large amounts of water losses, even from relatively small leaks. Therefore, water utilities should always aim to reduce ALR times to the economic minimum.
