The subject of the contract is the construction of a sanitary sewage system in the Kroczyce commune. The contract includes the continuation of activities in the field of water and sewage management in the Kroczyce agglomeration, including:
- construction of sanitary sewage system covering the following streets: partly Marianka, Kopernika, Topolowa, Jurajska and partly Kościuszki, which will be connected to the first stage carried out in 2017-2018,
- construction of a section of the water supply network connecting the end of the water supply in Jurajska St. with Topolowa St. on the section where it is missing.
The subject of the contract is the execution of the second stage of the construction of the sanitary sewage system covering the streets: partly Marianka, Kopernika, poplar, Jurajska and partly Kościuszki, which will be connected to the completed stage I.
Under the contract, gravity, pressure, pressure sanitary sewage system and sewage connections to the first well on the property are to be implemented. The connections from the first well to the building or drainage tank shown in the documentation are not included in the scope of works and will be made by the efforts of the owner of the property.
In addition, the task includes the construction of a section of the water supply network in Jurajska St. together with connections terminated with water meter wells.
The material scope of the contract includes:
- gravity sanitary sewage system with a diameter of 200 mm and length - 3 367.60 mb,
- discharge sewage system with a diameter of 90 mm and length - 712.20 m,
- pressure sewage system with a diameter of 50 mm and length - 60.00 m,
- pressure sewage system with a diameter of 40 mm and length - 132.40 mb,
- gravity sewer connections with a diameter of 160 mm and length - 839.60 mb,
- network pumping stations - 1 pc,
- backyard pumping stations - 7 pcs.
In total, 135 gravity and pressure house connections are to be made;
- water supply network with a diameter of 125 mm and length - 560.0 mb,
- water connections with a diameter of 40 mm and length - 309.50 mb.
A total of 37 water supply connections are to be made;
On the sanitary sewer route, reinforced concrete inspection chambers with a diameter of 1,200 mm were designed and plastic wells with a diameter of 425 mm on the connections. The water supply network will be equipped with gate valves, underground hydrants, gate valves for house connections and water meter wells.
The scope of works includes restoration of the surface of municipal roads after the works have been completed, in particular:
- restoration of pavement road surface with foundation around 2 350 m
- restoration of the foundation for asphalt roads of approx. 11,950 m
- restoration of asphalt surfaces approx. 11,950 m
Sewer along the national road [ul. Kościuszki] is run outside the road lane.
In communal roads with breakstone pavement, a foundation will be made as for KR2 roads along the width of the excavation and the surface [upper layer] along their entire width. In communal roads with asphalt surface, the foundation will be made as for KR2 roads along the width of the excavation, along with supplementing the foundation on the remaining width and asphalt layers along their entire width. The reconstruction of roads in the upper layer [crushed stone or asphalt] along the entire width is associated with their small width and compact construction, therefore the transverse passages for connections are very dense.
The task in the field of sanitary sewage system has full documentation of the construction of 4 stages. Under this contract, the last - II stage of sewage system will be built.
Stage I was carried out in the years 2017–2018. Currently, the implementation of the third and fourth stage.
