Waterworks Western Ore Mountains
The Westerzgebirge waterworks association (ZWW) was created on January 1, 1996 as the legal successor to the former Westerzgebirge municipal water supply and wastewater treatment association, which was founded on April 1, 1993 by 39 towns and municipalities in the Aue and Schwarzenberg districts.
As a purely municipal association, it has the task of supplying the population and the commercial sector with drinking water in its area of the association and of disposing of the wastewater and sewage sludge that occurs. All resolutions and decisions in the association are public and serve the goal of ensuring stable supply and disposal for the citizen at affordable prices and fees.
Wasserwerke Westerzgebirge GmbH
To increase efficiency and utilize synergies, the ZWW founded an operating management company on October 16, 1997, the Wasserwerke Westerzgebirge GmbH. She has taken over the management of the association for the drinking water sector and provides services in the wastewater sector.
From 1999 the area of the Westerzgebirge waterworks was gradually enlarged and the wastewater area re-established.
The following associations / areas were included:
- July 1, 1999 Wastewater associations Schwarzenberg, Bernsbach-Lauter, "Upper Schwarzwassertal", "At the drinking water dam Eibenstock"
- January 1, 2001 “Abtwald” and “Oberes Zwönitztal” wastewater associations and takeover of the drinking water supply for the districts of Günsdorf, Dorf-Chemnitz and Brünlos von Zwönitz
- January 1, 2005 Wastewater Association "Würschnitztal"
- January 1st, 2007 Takeover of the wastewater disposal of the district Adorf von Neukirchen
- January 1, 2009 Takeover of the drinking water supply for the town of Elterlein with the districts of Hermannsdorf and Schwarzbach
- January 1st, 2012 Takeover of the wastewater disposal of the city of Elterlein with the districts Hermannsdorf and Schwarzbach
To use the resources of the water supply and wastewater disposal in the environmental cycle, Wasserwerke Westerzgebirge GmbH founded Vererdungsanlagen Westerzgebirge GmbH with a private partner on December 4, 2004. The aim of this GmbH is to compost the sewage sludge, which mainly arises in the sewage treatment plants of the waterworks, in the context of open windrow composting and to soil it later. The company now sells up to 5,000 m³ of certified potting soil per year.
Expansion of the sewage network
The Saxon Water Act stipulates that all wastewater discharges comply with the "state of the art". Only the central wastewater connection of the ZWW and the decentralized fully biological small sewage treatment plant / drainless pit meet this requirement. In order to connect as many property owners as possible to the central sewage network between 2015 and 2020, the ZWW concluded a public law contract with the Erzgebirgskreis for the development of the sewage side. This contract grants property owners, who are still being developed centrally by the ZWW, from 2016 until the time of the central wastewater connection for their existing small sewage treatment plants / pits without drainage. At the same time, the ZWW undertook to connect a total of 3,250 sewage house connections for a total of 10,634 residents to its central sewage network between 2015 and 2020. The cost of this project is over € 45 million. Many property owners participate financially in this wastewater development.
Investments
In the first 20 years, the ZWW invested over € 260 million in its drinking and wastewater systems. In the area of drinking water, drinking water treatment plants, elevated tanks and pumping stations were built or expanded. Thanks to the gradual renewal of the 1,670 km long drinking water pipelines, it was possible to reduce network losses from over 55% (1990) to 8% (2016).
New central and group sewage treatment plants with cleaning technology were built in the wastewater area. Rain overflow basins and rain storage channels were built for the targeted drainage of rainwater. In 2016, 88% of all residents in the area of the ZWW disposed of their wastewater centrally via the 790 km long sewer network of the ZWW, which is new in many places. In 1990 this proportion was only 30%.
From the middle of 2013, the ZWW began to gradually generate its own energy and heat for its own use using micro gas turbines and photovoltaic systems. Thanks to the self-produced amount of energy, intelligent control of the quantities required, but also through the use of energy-saving technologies in pump technology, the association's external energy consumption has been reduced by 24% since 2012.
In 2017, the Westerzgebirge waterworks intend to invest € 17.190 million in their systems.
Association area
The Westerzgebirge waterworks are currently responsible for supplying and / or disposing of drinking water and wastewater for 161,500 residents. The supply and disposal area of the Westerzgebirge waterworks association and the Westerzgebirge GmbH waterworks differ in their communal boundaries (areas of the wastewater disposal company Saxony and the water supply company Saxony).
The cities and municipalities listed belong to the respective area of drinking or wastewater and are therefore the responsibility of the ZWW.
