The Zweckverband Water and Wastewater Treatment Rügen (CHAT) operates the Göhren wastewater treatment plant in Göhren on Rügen, which has an approved expansion size of 30,000 EW. With the steadily rising tourism on the island of Rügen, the inlet load has increased significantly since the last expansion of the wastewater treatment plant. The Göhren wastewater treatment plant has reached its capacity limit and needs to be expanded.

The expansion of the wastewater treatment plant is divided into 3 sections:

a) Renewal of the blower station/ conversion of aeration tanks 1 and 2 (under construction) b) 1st construction phase - new aeration tank 3 (to be realized now) c) 2nd construction phase - renewal of post-clarification/renewal of preliminary mechanical cleaning (to be implemented in the future)

Scope: Equipment aeration tank 3 consisting of aeration system (membranes), agitator, recirculation pumps, fittings and pipeline construction; equipment inlet distributor Revitalization and feed distributor Reclamation consisting of automatic valves; Equipment floating sludge pump station consisting of pumps, fittings and pipeline construction; partial renewal Precipitating agent station consisting of dosing cabinet, pumps, fittings, piping and measurement technology;

Scope: Dismantling of distribution structure revitalization (earthworks, dismantling work),

New distribution structure, revival (earthworks), new aeration tank 3 (water retention, earthworks), new distribution structure, re-clarification (earthworks), earth and surface work (dismantling and new construction)

Scope: New distribution structure livenation (concrete, steel construction,

pipeline work), new aeration tank 3 (concrete construction,

steelworks), new distribution structure (concrete construction,

steelwork)

Scope: Underground pipelines (dismantling and new construction) in the area of revitalization and clarification, pipe trenches, shaft constructions, EMSR containers (with foundation)

As part of an extension project, the Göhren sewage treatment plant will be equipped with a 3 aeration tank. The process plant of the aeration tank is connected to the energy supply and control technology network of the Göhren sewage treatment plant via a new concrete precast station set up at the head of the pool. In this station, the control cabinets for energy supply and measurement and automation technology are in the final stage of installation. The media lines required for energy supply and control technology can be drawn into the company building via an existing empty conduit system. The cables and lines on the aeration tank itself are laid in a cable path fastened to the edge of the pool.
