Reconstruction and expansion of Kiev sewage works (Ukraine)
The Kiev-Bortnyz’ka works treats about 1.0 million m³ of wastewater a day. The current connected load is around 3.7 million inhabitants. The Kiev city council forecasts an increase of waste water quantities to >1.5 million m³/d and inhabitants to 5.34 m by 2021.
Because of the poor state of repair of the existing plant elements and the inadequate cleaning capacity, extensive reconstruction of the sewage works is required. In addition, 2 main pumping stations need to be reconstructed and a new pumping station with a capacity of 600,000 m³/d erected. The strict cleaning requirements require the construction of downstream biofilter systems for residual denitrification. Furthermore, the purified wastewater needs to be disinfected before being discharged into the Dnieper. Two treatment trains, each with approximately 270,000 m³ aeration volume and 16 secondary sedimentation basins with a diameter of 48 m are being constructed from scratch. One existing treatment train can be structurally upgraded.
Our planning office is commissioned with the implementation of a feasibility study and with all work phases of the planning and on-site construction management.
