Wastewater Association

What Wastewater Association does

AbwasserVerband Weyhe is a statutory municipal Zweckverband (public-law purpose association) jointly formed by the municipalities of Stuhr, Weyhe, and Samtgemeinde Harpstedt in Lower Saxony, Germany, with headquarters in Weyhe. The association provides integrated wastewater management services to more than 75,000 residents across the three member municipalities, operating a Trennsystem (separate sewer system) with pipe diameters ranging from DN 150 to DN 800, pumping stations, rain retention basins, and canal maintenance equipment including two high-pressure flushing vehicles and CCTV inspection systems. Wastewater is transported under contract to central treatment plants operated by Hansewasser Bremen, Stadt Delmenhorst, and Gemeinde Goldenstedt, while the association also oversees 811 decentralized small treatment plants (Kleinkläranlagen) and 60 sealed collection pits (abflusslose Sammelgruben), predominantly in Samtgemeinde Harpstedt.

The service portfolio spans domestic and commercial wastewater collection (Schmutzwasserbeseitigung), separate stormwater drainage (Niederschlagswasserbeseitigung), industrial/indirect discharge monitoring with pollutant cadastre maintenance, property connection construction and inspection, backflow protection advisory, decentralized sludge disposal, 24/7 emergency response, and—since January 2009—a Rechnungsprüfungsamt (municipal audit office) serving the administrations of Stuhr and Weyhe.

Revenue is generated almost entirely through regulated, usage-based wastewater fees under the Abwasserbeseitigungsabgabensatzung: €3.64 per cubic meter for the standard central system (annual billing), €50.60 per cubic meter for sealed pit contents, and €95.80 per cubic meter for small treatment plant sludge (effective January 1, 2025). Meter reading is performed by water suppliers OOWV and Wasserversorgung Syker Vorgeest, with approximately 90% of customers paying via SEPA direct debit. The entity is non-profit (gemeinnützig), governed by a Verbandsversammlung and Verbandsausschuss, and holds exclusive statutory authority for wastewater disposal within its member municipalities.
