Phase five of a large investment programme entitled ‘Waste Water Master Plan for Warsaw’ is underway. It is co-financed by the European Union and focuses on water supply and waste-water management. This phase, which is being implemented in the city of Warsaw and the municipalities of Pruszków and Serock, includes development of a central sewage network management system.
- 28 July 2017
The main scope of the work comprises the construction of 1 km of water-supply network and 40 km of new sewers, as well as modernisation of 26 km of the existing sewage network. Five sewage pumping stations will be rebuilt and a new one built from scratch.
A sewage reservoir with a capacity of 78 000 m³ will be created on the site of the Czajka waste-water treatment plant, while the Zakład Północny waterworks are to be modernised. The project also includes the introduction of a geographic information system and implementation of energy-efficiency measures.
The Waste Water Master Plan for Warsaw was launched in 2004. The size and functioning of the fifth phase have been determined by the inadequacies documented in previous phases and the water supply and sewage system modelling initiative launched under the fourth phase. Although fully complementary to the previous four phases, the current project is functionally, technically and financially independent of them.
Meeting environmental standards
The strategic objective is to ensure that Warsaw’s waste-water infrastructure complies with the EU’s environmental standards, as well as with the requirements of Poland’s national programme for urban waste-water treatment. In this respect, the project aims to optimise water and waste-water management by enhancing access to the water supply and waste-water collection and treatment systems. It will connect 13 200 inhabitants to the waste-water network and 4200 to the water-supply network.
Other benefits include less leakage from and infiltration into the networks and an increase in the networks’ retention capacity. Greater sewage retention will help to reduce the amount of storm discharge into the River Vistula and resulting contamination of the Baltic Sea, as well as making it safer to operate the sewage network.
A secure and reliable water supply
The work will improve the security and reliability of Warsaw’s water supply in terms of both quantity and quality. Construction of the reservoir at the Czajka waste-water treatment plant and the central sewerage network management system will help to ensure even distribution of waste water in the system, including during storms.
The central management system will also contribute to reducing the occurrence of flooding resulting from heavy rainfall. Higher levels of energy efficiency brought about by the project will cut carbon dioxide emissions from the networks by around 11 500 tonnes a year.
Total investment and EU funding
Total investment for the project “Water supply and wastewater management in Warsaw – Phase V” is EUR 247 443 908, with the EU’s Cohesion Fund contributing EUR 128 247 613 through the “Infrastructure and Environment” Operational Programme for the 2014-2020 programming period.
