Wasserversorgung Sulinger Land

What Wasserversorgung Sulinger Land does

Wasserversorgung Sulinger Land is a public-law Zweckverband (municipal utility association) headquartered in Sulingen, Lower Saxony, providing drinking water supply and wastewater disposal services to approximately 32,000 residents across four Samtgemeinden — Kirchdorf, Schwaförden, Siedenburg, and the city of Sulingen. Founded in 1963 as a municipal enterprise and reorganized under the Zweckverbandsgesetz in 1964, the entity has operated as a non-profit association governed by the Verbandsversammlung and managed by Verbandsgeschäftsführer Andreas Geyer. It holds a legally mandated monopoly over water and wastewater services in its designated area, with no competing providers permitted.

The company owns and operates the full infrastructure chain: three waterworks (Kirchdorf, Schwaförden, Sulingen) with 14 groundwater wells up to 60 m depth, 3,500 m³ combined storage capacity, and treatment covering iron/manganese removal and deacidification; an 820 km water distribution pipe network serving ~11,000 installed meters; and four wastewater treatment plants (Ehrenburg, Sulingen, Varrel, Kirchdorf) with a combined capacity of 31,500 population equivalent, supported by 157 km of sewer, 74 km of pressure pipeline, and 149 pump stations. Treatment achieves up to 98% pollutant removal, including mechanical screening, biological phosphorus removal with iron III dosing, and full biological carbon/nitrogen treatment. Groundwater protection is supported by a long-running partnership with farmers in water extraction zones (since 1994). Quality is monitored through accredited laboratories, with hardness ranging from 6.8°dH (Kirchdorf) to 9.5°dH (Sulingen), all complying with the German Trinkwasserverordnung. The organization has held DIN EN ISO 9001 certification since February 2000, reportedly among the first in the German water utility industry.

Revenue is generated entirely through usage-based fees regulated under the Lower Saxony Municipal Levy Law (Nds. Kommunalabgabengesetz) and set by independent auditors: water supply at €6.42/month basic fee plus €2.48/m³ consumption; wastewater at €5.15/m³; plus connection fees (€1.07/m² and €2.00/m²), standpipe rental (€3.00/day, €40.00 minimum), and decentralized tank emptying fees. New tariffs took effect January 1, 2026. As a non-profit, the entity reinvests all revenue into infrastructure maintenance and is explicitly barred from generating profit. Customer interaction is supported by a BundID-authenticated online Kundenservice-Portal for meter readings, billing, connection applications, ownership changes, document downloads, and disruption notifications.
