Supplementation of the water management infrastructure of the city of Pilsen

This project addresses the issue of the sewage deficit and the elimination of deficiencies in the drinking water supply.

The project includes a set of six structures - the Lobzy and Vinice waterworks, the Gera and Bolevec retention tanks, the Valcha sewerage system and the Křimice, Radčice and Lochotín sewerage system.

  • The first type is the retention tanks. Their function will be to retain water during heavy rains so that the water does not overwhelm the sewage system and is treated within the MP sewerage network.
  • The second type of structures are the main water supply networks that will lead to the urban areas of Lobza and Vinice. This means an improvement in water quality and an alternative source of drinking water for the Northern Suburbs.

The third type is the sewage systems in Křimice, Radčice and Valše.
The construction of a sewerage system with a total length of about 14 km in the outskirts of the city of Plzeň will ensure the treatment of wastewater before it is discharged into the Berounka River. The aim of the project is to build structures that will solve the sewage deficit, clean wastewater and eliminate the shortcomings in the drinking water supply of the city of Pilsen, especially in its peripheral parts.

Sewerage systems in Křimice, Radčice and Lochotín

The sewage sewerage system will have a total length of approximately 14 kilometres, of which almost 6 kilometres will be pressure sewers. The sewerage system will enable full-fledged housing in the outskirts of Pilsen and, as it will be connected to the existing sewerage system of the city, will guarantee quality treatment of wastewater at the city's WWTP before it is discharged into the Berounka River.

Valcha sewerage system

The sewage sewerage system will have a total length of about 9 kilometres, of which about 2 kilometres will be a pressure sewer made of ductile iron. The sewerage system will be connected to the existing Lititz interceptor. Pumping of sewage will be provided by 5 pumping stations.

Gera retention tank

The construction will be located behind Bolevecka Street near the university dormitories. The Gera retention basin is designed as an underground reinforced concrete monolithic structure with a usable retention volume of 2350 m3. The retention basin will be built to reduce the flow rate of wastewater in the sewerage collector, particularly during heavy rainfall, thereby reducing the risk of damage to the sewerage system and ensuring future treatment in the retention basin of temporarily collected wastewater before it is discharged into the river. The construction includes a water supply connection for cleaning the tank, an electrical connection, a dedicated road connecting the construction to the urban communication network.

Lobzy waterworks complex

The Lobzy water supply system will consist of a drinking water discharge line from the Homolka water reservoir through the Slovany and Lobzy districts to the site of the newly proposed Lobzy water reservoir. The Lobzy water reservoir is designed to draw drinking water with a total volume of up to 2 x 10,000 m3. The construction of this water reservoir will eliminate problems with the drinking water supply in the urban area of Lobzy and Doubravka, especially along Rokycanská Avenue, where insufficient pressure in the network causes problems in the drinking water supply. The water supply system will also include the construction of interconnecting lines. The total length of the pipelines will be approximately 7 kilometres.

Bolevec retention tank

The construction will be located on the U Velkého rybníka road near the railway line to Žatec. The Bolevec retention basin is designed as an underground reinforced concrete monolithic structure with a usable retention volume of 3100 m3. The retention basin is being built to reduce the flow rate of wastewater in the sewerage collection system, particularly during heavy rainfall, thereby reducing the risk of damage to the sewerage system and at the same time ensuring future treatment in the retention basin of temporarily collected wastewater before it is discharged into the river. The construction includes a water supply connection for cleaning the tank, an electrical connection, a dedicated road connecting the construction to the urban communication network.

Vinice waterworks complex

The main object of the Vinice waterworks complex will be a water tank with a total storage capacity of 2 x 6000 m3 of drinking water. The waterworks complex will also include connecting lines and the connection of the reservoir to two discharge lines to the Sylván reservoir. The Vinice water reservoir will facilitate the supply of drinking water to the Roudná district, parts of Lochotín, Vinice and the city centre. At the same time, it will be possible to decommission the old and faulty discharge line from the Bory water reservoir to the Sylván water reservoir in the near future.

Expected start of work

The project of the Supplementation of the Water Management Infrastructure of the City of Pilsen has been prepared and developed over a number of years, a lot of work and effort has been put into it and the actual implementation is the culmination of this project. The construction will affect more than a third of the population of the city of Plzeň, mainly in the northern suburbs, Radčice, Křimice, Valše and Lobze. It may mean a short-term deterioration of housing on the construction site, but it represents a huge investment in the future, especially for a significant improvement in the quality of life of the citizens of Pilsen. Building permits have been issued for all the buildings and construction can be expected to start in autumn 2006. It is planned to put the buildings into operation by the end of 2008 at the latest.
