Detailed Design and Design Supervision of sewerage pumping
station on Daugavgrīvas Str. 101 (Riga, Latvia)



Contractor: "Rīgas ūdens" Ltd., 2017



Detailed
Design and Design Supervision 



Project
provides the construction of a new sewerage pumping station in Riga, on Daugavgrīvas
street 101. For now, it is the largest sewage pumping station in the Baltic
States. 



Designed
capacity – 2300 l/s or 8280 m3/h



The design provides the safe collection and pumping of wastewater from the areas of the left bank
of the Daugava to the BTP "Daugavgrīva". 



The benefit from the reconstruction of the pumping station will be the reduction of
technological water consumption, as well as the saving of electricity
consumption. The new sewerage pumping station will be significantly more
environmentally friendly and safer.
