Since the fall, preparations have been underway to connect the burkardroth districts of katzenbach, lauter and waldfenster to the clarification plant in grobenbrach. Now the engineer hugo barthel (proterra, knetzgau-zell), who was commissioned by the wastewater association aschach-saale, presented his plans to the association members from the municipalities of burkardroth and bad bocklet. He was then unanimously entrusted with the continuation of outstanding tasks.
The first considerations as to where the wastewater from the three burkardroth districts should be discharged in the future were made ten years ago. But it was not until the summer of 2012 that burkardroth decided to expand its membership in the aschach-saale wastewater association and to connect katzenbach, lauter and waldfenster to the clarification plant in grobenbrach. This decision had become necessary because the previous plant in katzenbach no longer met the requirements of the authorities and was to be abandoned.
One possibility would have been to feed the wastewater to the hammelburg clarification plant. But rough cost estimates had shown an investment of almost four million euros and annual operating costs of about 70,000 euros. This would have been more expensive than the technically simpler connection to the grobenbracher clarification plant with a one-time investment of only 2.1 million euro and annual operating costs of just under 85,000 euro.
Overhaul to stralsbach
Hugo barthel now explained the technical requirements to the association committee, chaired by deputy district administrator emil muller and in the presence of mayors waldemar bug (burkardroth) and wolfgang back (bad bocklet), calculated from the expected additional wastewater and rainwater volume of the three villages with almost 2,000 inhabitants.
For the connection to the grobenbracher clarification plant, the construction of a two-story pumping station with connected flow basin and retention basin on the outskirts of katzenbach is necessary. Barthel: "there will be no odor nuisance for the residents." From there, the wastewater is to be pumped through a pipeline over a higher level, where an industrial area is planned, to stralsbach, where it will be discharged into the existing wastewater system.
The land negotiations required for the construction of the pumping station and the laying of the pipeline have been largely completed successfully, informed chairman emil muller. Only details of the exact route still need to be clarified, which will require additional negotiations. Talks have also been held with the nature conservation authorities, as the pipeline is to cross two wetlands.
The members of the association commissioned proterra to continue the work. This still includes the preparation of building ground surveys, the clarification of the land issue for the construction of a rainwater retention basin in waldfenster and coordination discussions with the water management office.
Proterra announced the presentation of the final construction design for the coming spring. Construction will not begin until 2015, however, emil muller dampened overly high expectations. "We want to continue with the necessary orderliness and punctuality, but without unnecessary time pressure."
