Co-financing Agreement for Wastewater Transit from Bydlino Signed
On December 9 of this year, a co-financing agreement for the project titled “Development of design documentation and construction of a wastewater transit system to the Słupsk agglomeration from remote localities of the Redzikowo Commune” was signed at the headquarters of the Regional Fund for Environmental Protection and Water Management in Gdańsk. The funding has been granted in the form of a subsidy and a preferential loan. The investment is co-financed by the Regional Fund for Environmental Protection and Water Management in Gdańsk under the “Szlamnik – improving the operational efficiency of wastewater treatment plants” program. The beneficiary of the support is “Wodociągi Słupsk” Sp. z o.o. (Słupsk Water Utilities).
The maximum value of the co-financing amounts to PLN 3,000,000.00 in the form of a subsidy and PLN 4,500,000.00 as a preferential loan. Meanwhile, the planned eligible cost of the project is estimated at PLN 8,600,000.00.
The supported project consists of developing design documentation and constructing a wastewater transit system from the locality of Bydlino and other localities within the Redzikowo Commune situated far from the wastewater treatment plant, covering the area of the Słupsk agglomeration. The development and needs of existing entities in the areas adjacent to the original borders of Bydlino are currently limited due to the lack of wastewater disposal capabilities. The currently operating sewerage system is unable to increase transit capacity because of the limited throughput of the existing sanitary sewerage network. In contrast, the wastewater treatment plant in Słupsk has the capacity to receive larger volumes of wastewater from this area. Therefore, the best solution proved to be designing and constructing a sufficiently efficient transit system that accommodates development needs and additionally resolves existing hydraulic and odor issues in the localities along the route to the treatment plant. The planned route of the sewage collector will be located within the following geodesic precincts: Bydlino, Włynkówko, Włynkowo, Swochowo, and Siemianice in the Redzikowo Commune, as well as precinct no. 0002 in Słupsk. The area where the investment will be implemented is partially developed, consisting mainly of residential buildings, with parts designated as agricultural and forest lands. It is planned for the collector to pass beneath the Słupia River.
It is anticipated that within the next 3 years, approximately 150 additional residents from the localities of Bydlino, Włynkowo, and Włynkówko will connect to the constructed network.
As a result of hydraulic overloading, situations occur where the gravity sewerage network operates under pressure, which hinders and complicates maintenance work on both the sewerage network and wastewater pumping stations.
The lack of connection capabilities halts the economic development of existing plants within this catchment area as well, leading to relocation and economic slowdown in this part of the commune.
The planned scope of the investment includes:
- development of design documentation along with obtaining the necessary approvals and permits;
- construction of a PE225 discharge pipeline with a length of approx. 7,900 m from the existing PE200 pipe to the distribution chamber at the wastewater treatment plant, and from the designed wastewater pumping station at Orzechowa Street in the area of Słupska Street in Bydlino using PE110 pipes – approx. 50 m;
- construction of one network wastewater pumping station;
- reconstruction of two existing network pumping stations in the locality of Bydlino (replacement of pumps, control systems, metering, visualization of the status and operating parameters of the facilities).
Executing this scope of investment will eliminate existing hydraulic issues, enable the connection of new customers, and foster the economic development of areas located close to the coastal zone.
The implementation of the investment will contribute to preventing the negative impact of hydrogen sulfide, which, apart from social issues, also causes severe and hazardous phenomena related to network operations and rapid corrosion of concrete surfaces and network equipment (automation, electrical components, metal surfaces, pump bodies, and impellers, etc.).
The current risk of overflows from the overloaded transit network affects Natura 2000 sites directly adjacent to the Słupia River, spanning from the locality of Włynkówko all the way to the wastewater treatment plant in Słupsk.
The investment will also relieve the sewage collector along Portowa Street, increasing its capacity to receive industrial wastewater from fish processing plants currently operating in the economic zone and expanding their processing potential.
The objective of the task is to equalize civilization standards across the entire area of the Company’s sewerage operations and to ensure the accessibility of sewerage services for all residents of the Redzikowo Commune. The priority is to implement the principle of social justice for all residents and to ensure the affordability of the provided sewerage services.
The implementation of the task will contribute to improving environmental quality standards and reducing environmental pollution by:
- creating capabilities to treat wastewater from new development areas of the Redzikowo Commune located outside the agglomeration at the wastewater treatment plant in Słupsk (350,000 PE) with the highest quality standards, along with the safe management of sewage sludge;
- unlocking socio-economic development within the catchment area of the existing collector, which will contribute to reducing illegal discharges from activities operating outside the sewerage system (without complying with the issued technical conditions for connection);
- eliminating uncontrolled overflows from the overloaded Bydlino – Słupsk wastewater treatment plant sewerage system, particularly during atmospheric events in Natura 2000 areas;
- eliminating odor phenomena, i.e., accelerated corrosion and wear of sewerage equipment, as well as threats to the health and life of maintenance personnel;
- improving the energy efficiency of the wastewater transit system.
Planned project completion date: June 2028.
