The municipality of Mainhardt currently operates four sewage treatment plants in Gailsbach, Bubenorbis, Schönhardt (reed treatment plant) and Mainhardt. As part of a structural report, a merger at the sewage treatment plant in Mainhardt was recommended. The reconnection of the Schönhardt sewage treatment plant has been decoupled and is already in progress. For the connection of the other two sewage treatment plants, the sewage treatment plant in Mainhardt is to be expanded to around 13,000 p.e. A planning office is being sought for this purpose.
In a parallel tender, the planner for the routes and pumping stations to connect the sewage treatment plants to the sewage treatment plant in Mainhardt is being sought (www.subreport.de/E14286381).
The contract includes the planning services and the execution of the conversion of the Mainhardt wastewater treatment plant, taking into account the plant technology currently available on the market, which combines high operational availability and reliable operability with technical innovation.
