Largest sewerage pumping station in Riga
On July 11, 2024, the largest sewerage pumping station was opened in Riga at 101 Daugavgrīvas Street with the participation of representatives of the Riga City Council, the management of SIA "Rīgas ūdens", as well as the builders and engineers involved in the project. This 8.7 m high monolithic reinforced concrete building with a 10.8 m deep underground part and the cost of the project reached 13.4 million euros. The new station is an important investment in the city's infrastructure, which allows efficient collection and pumping of wastewater from the left bank of the Daugava to the Biological Treatment Station "Daugavgrīva".
The construction of the object started in the spring of 2021, it was carried out by the construction company SIA "Velve”. The station ensures the collection and pumping of wastewater from the neighborhoods of the left bank of the Daugava to the Biological treatment station "Daugavgrīva".
In 2023, the pumping station pumped total of 25 million cubic meters of wastewater, which is about half of all Riga's wastewater. The old and now demolished sewage pumping station at 101 Daugavgrīvas Street operated for more than 30 years, and it had served its time both technically and morally.
From economic point of view, the biggest benefit from the new station is the saving of technological water and electricity consumption. If approximately 300,000 m3 of water were required for cooling the equipment of the old station, then in the new station, water will not be used for cooling at all, but the electricity consumption is planned to be reduced by approximately 2.5 million. kW or 55% per year.
SIA "Aqua-Brambis" is the author of the project of this object and performed the author's supervision during construction.
