Works at the Farysa plant in Warsaw have been completed as part of a renovation and modernisation project planned and carried out by Wodociągi Warszawskie (Warsaw Waterworks) in response to a failure in 2020, which resulted in a leak in the pipelines running under the Vistula River and transporting sewage to Czajka.
The Farysa plant is a technical infrastructure responsible for the flow of sewage from the entire left bank of Warsaw to the Świderska plant located on the right bank and further to Czajka. The plant consists in particular of a screen building and an expansion chamber. Our task was to carry out restoration works on the technological installations for screenings collection at Farysa, as well as to renovate the connection chamber (gate valves) at the Świderska plant.
Therefore, a comprehensive modernisation of the technological system for the transmission of Warsaw sewage was carried out on the section entrusted to us in order to strengthen its resistance to failures that could result in significant environmental pollution.
Work was carried out during operation of the plant, coordinating with another contractor working in parallel in the tunnel under the riverbed.
