Zweckverband Zur Wasserversorgung

What Zweckverband Zur Wasserversorgung does

Zweckverband zur Wasserversorgung der Alto-Gruppe is a public-law water utility association (Zweckverband) headquartered in Markt Indersdorf, Bavaria, that supplies drinking water to approximately 31,756 residents across five member municipalities — Altomünster, Markt Indersdorf, Röhrmoos, Vierkirchen and Weichs — in the Dachau district. The organization was constituted on 12 May 1993 to consolidate fragmented local water cooperatives and is supervised by the Landratsamt Dachau; it is governed by a 15-member Verbandsversammlung with day-to-day operations run by a works committee and Geschäftsleiter Hans-Peter Unsinn.

The association's core product is continuous drinking water supply, produced from five deep wells (depths 42–158 m) and four treatment plants (capacities 15–70 l/sec), stored in three elevated tanks with combined 6,700 m³ capacity, and distributed through a ring-interconnected network of 290.39 km of main pipelines and 113.93 km of property connections serving 8,771 installed meters and 1,586 hydrants. The ring architecture guarantees uniform water quality across the territory and provides automatic emergency interconnection with three neighboring water associations (Weichlach-Gruppe, Zweckverband Freising-Süd, Sulzemoos-Arnach-Gruppe). The 2025 extraction volume was 1,800,327 m³, of which 1,591,834 m³ was sold — the gap representing system losses and internal use.

Revenue is generated through a regulated tariff under the Beitrags- und Gebührensatzung, comprising a consumption fee of €1.40 net/m³ (€1.50 gross), a base fee scaled to meter size ranging from €48 to €600 net annually, one-time connection contributions (€1.20/m² property area, €7.38/m² floor area gross), construction water flat rates, portable meter rentals, and reimbursable property connection charges. From 1 July 2026 the new Bavarian Wassercent (10 cents/m³ of extracted groundwater) will add approximately €170,000 of annual cost, to be incorporated into the consumption and base fee schedule from 1 January 2027.

Regional players

• Weichlach-Gruppe: Neighboring Bavarian water supply association with emergency interconnection to Alto-Gruppe. Direct operational peer in service model (Zweckverband, regulated monopoly) serving overlapping geography west/northwest of Alto-Gruppe.
• Sulzemoos-Arnach-Gruppe: Neighboring water supply association south of Alto-Gruppe with emergency interconnection. Same small-municipal Zweckverband operating model in the Dachau/Fürstenfeldbruck area.
• Zweckverband Freising-Süd: Neighboring water Zweckverband east of Alto-Gruppe with an automatic emergency interconnection. Operates the same municipal-association public utility model in adjacent Bavarian districts.

Direct peers

• Zweckverband Landeswasserversorgung Baden-Württemberg: Regional long-distance water supply association under public law, supplying member municipalities across Baden-Württemberg. Shares the Zweckverband governance model, multi-member structure, and ring-distribution approach.
• Zweckverband Bodensee-Wasserversorgung: Large Bavarian/Baden-Württemberg water supply Zweckverband serving municipal members. Operates with a similar public-law utility model, ring/multi-source distribution and Trinkwasserverordnung compliance, but at substantially larger scale.
• Zweckverband Wasserversorgung Isar-Vils: Bavarian Zweckverband supplying drinking water to multiple member municipalities in the Isar-Vils catchment. Direct structural peer with similar legal form, pricing model, and reliance on Bavarian groundwater.

Broad incumbents

• Gelsenwasser AG: Large German water utility active across multiple federal states with municipal shareholders. Comparable business model (municipally anchored water supply) and same regulatory regime (Trinkwasserverordnung), but operates at much larger scale with regional subsidiaries.
• Stadtwerke München (Münchner Stadtentwässerung / Trinkwasser): Munich's municipal multi-utility, including drinking water supply from the Mangfalltal system. Comparable product (drinking water utility) but vastly larger scale, broader service portfolio, and incumbent operator in Bavaria.
• Oldenburgisch-Ostfriesischer Wasserverband (OOWV): Major regional water and wastewater association serving northwest Lower Saxony. Comparable public-law utility model and broad membership base of municipalities, but at significantly larger geographic scale.

Others

• Wasserwirtschaftsamt Dachau: Bavarian state water management authority that supervises water rights and supply in the Dachau district where Alto-Gruppe operates. Regulatory and oversight counterpart rather than a direct competitor; relevant for understanding the supervisory framework.
