Sewerage and WTP Jamné

The project involves a new sewage system for the entire Jamné municipality concluded with a new water treatment plant with a capacity of 600EO.

Construction period: 2017/03 - 2018/09
Total value of the contract: 54 696 347 CZK excluding VAT

Currently, a unified sewerage network is operating in the municipality, however, it is not connected to a WTP. After completion of the construction of a new sewerage system, the existing sewage system will be used solely for drainpipe.

Sewerage is designed primarily as a gravitational DN 250 mm in the length of 3,835.2 m. In areas where, due to the depth, it is impossible to use the gravity pipelines, the pressure sewer in the length of 836.3 meters is designed. The sewer pumps waste water of the three sewage pumping wells back into the gravity system. The fourth pumping station is located in front of the new mechanical-biological waste water treatment plant and pumps all the municipality´s sewage into the tanks of the water treatment plant. Treated waste water flows back into the nearby watercourse.
