Extension of the Blaufelden sewage treatment plant
Central wastewater disposal in the municipality of Blaufelden

Due to unsatisfactory conditions in wastewater disposal in the districts of Wiesenbach and Gammesfeld, several renovation options were examined with regard to economic efficiency and environmental friendliness. As a result, the municipality of Blaufelden has decided to shut down the separate sewage treatment plants in Wiesenbach and Gammelsfeld as well as three other districts. In future, the wastewater produced here is to be diverted to Blaufelden and treated in the extended collective sewage treatment plant. With this reorganisation, environmentally friendly and economical wastewater treatment and the protection of regional waters can be improved and secured in the long term. The new wastewater pipes are laid using various methods with different stress potentials (open laying in trenches, milling and horizontal directional drilling techniques). In order to fulfil these sometimes high demands on the pipe material, the decision was made to use stress crack-resistant RCprotect^® pipes from Gerodur. To enable any subsequent camera inspections (TV inspections) to be carried out efficiently, the pipes were manufactured in 3 layers with a light-coloured inner layer at the client's request.
