GSW Gemeinschaftsstadtwerke GmbH intends to build a new combined pool on the site of the current outdoor pool.
For this purpose, the civil engineering work with soil and drainage work will be put out to tender. Services are to be carried out for earthworks including soil disposal, the construction of rainwater and waste water pipes including shafts, delivery and installation of packing trenches with special shafts, the installation of sedimentation systems for rainwater purification, delivery and manufacture of a pump system with pressure line and the production of ballast base courses.
Newly laid SW cables are connected to existing shafts.
For the RW drainage, a retention trench with pressure drainage into the Seseke stream will be built in the area of the sunbathing lawn.
