Engineering services for centralizing wastewater treatment in cores; Expansion and modernization of the sewage treatment plant in Krattenbach; Construction of a pumping station and a pressure line.

The municipality of Kernen currently operates the Haldenbach, Krattenbach and Beibach wastewater treatment plants with a total size of a nominal 26,000 PE. Wastewater treatment is to be centralized. The incoming wastewater from the Haldenbach and Beibach sewage treatment plants is to be transferred to Krattenbach. At the Haldenbach sewage treatment plant, a new pumping station for a volume flow of up to 75 l / s is required for the planned transfer of the wastewater. The Haldenbach sewage treatment plant is largely dismantled. The existing aeration tanks will be converted into emergency tanks and will remain intact. From the new pumping station, a new pressure line with a length of approx. 4 km is required past the Beibach sewage treatment plant, where an additional 27 l / s is added, to the inlet channel of the Krattenbach sewage treatment plant. A total of up to 102 l / s then arrive there. The planning services for work phases 5 to 9 required for the centralization of wastewater treatment in cores as well as the local construction supervision are part of this contract award procedure. Lot 1 includes the conversion and dismantling of KA Haldenbach and KA Beibach, the construction of the pumping stations and the pressure line. The construction costs are estimated at EUR 2.3 million net.
