Information on the Company’s investments completed in 2021 and scheduled for implementation in 2022.
In 2021, despite the challenging period related to the epidemic situation in the country caused by Covid-19, the Company continued its investment and renovation process aimed at eliminating identified system deficiencies and expanding it for new service recipients. The projects undertaken by the Company during this period primarily involve the execution of investments consisting in:
the expansion and reconstruction of the wastewater treatment plant,
the construction and reconstruction of the sanitary sewerage network,
the construction and reconstruction of water supply networks.
In 2021, the following investment tasks, among others, were completed:
within the city of Słupsk:
As part of the final phase of the Project entitled: “Circular economy in the wastewater treatment plant along with the expansion of the water and sewerage network in the Słupsk agglomeration” under OPE 2014-2020:
a/ Modernization of the biological treatment chamber aeration system including blower replacement and control system;
b/ Installation of dry anaerobic digestion of a part of green waste originating from the Słupsk county;
c/ purchase and replacement of a high-efficiency dewatering centrifuge at the wastewater treatment plant in Słupsk.
In addition, investments significant for the development of the city of Słupsk were completed, including among others:
a/ Modernization of the water supply and sanitary sewerage network in Zygmunta Augusta Street;
b/ Construction of the water supply network in the area of Legionów Polskich – included in the Local Spatial Development Plan (MPZP) for Zaborowskiej 1;
c/ replacement of the water supply network in Grzybowej, Kniaziewicza, Chopina, and Małachowskiego Streets;
d/ Modernization of the water supply network in Szarych Szeregów Street;
e/ Implementation of a UV system for the disinfection of treated water at the Water Treatment Station at Bohaterów Westerplatte Street.
2. As part of capital purchases, 2 electric-powered NISSAN vehicles up to 3.5 tonnes were purchased. The SCADA system supervising and controlling wastewater treatment processes at the Wastewater Treatment Plant in Słupsk was modernized.
within the Kobylnica Municipality, the following was completed:
Replacement of the water supply and sewerage network along with property connections in the village of Bzowo – stage II of implementation (by the road towards Ścięgnica).
Furthermore, in 2021, the implementation of an international partnership project entitled: “Protecting the Baltic Sea from untreated wastewater spills during floods in urban areas (NOAH)” was completed, co-financed by the European Regional Development Fund under the INTERREG Baltic Sea Region Programme 2014-2020, Priority 2: Efficient management of natural resources, Action: 2.1. Clean water. As part of this project, the following items, among others, were purchased:
- 6 pieces of precipitation measuring devices (rain gauges) along with a system for automatic data archiving, remote transmission, and visualization in dedicated software.
- 12 pieces of devices for measuring the filling level of main sewerage channels along with a system for automatic data archiving, remote transmission, and visualization.
laboratory equipment for wastewater quality testing, software and visualization, laboratory materials, including reagents.
The NOAH project implemented by “Wodociągi Słupsk” Sp. z o.o. aims to examine the impact of precipitation of various intensities, ranges, and durations on the existing sewerage system operating in the city of Słupsk. The construction of a monitoring system encompassing channel filling level measuring systems and rain gauges will allow for the examination of the correlation between the intensity and range of precipitation in relation to the filling of the sewerage network, the volume of discharged accidental water from rainfall, the frequency of storm overflow activation into the river, and consequently, determining the volume and dilution ratio of sanitary wastewater with rainwater discharged into the Słupia River and further into the Baltic Sea.
In 2022, it is planned to continue and complete the initiated investments, including among others:
- Construction of a heating network with a power cable from the wastewater treatment plant to the Trzy Fale Water Park
2. Expansion of the cogeneration unit system with a new 500kW el. unit;
3. Construction of a cable line from the wastewater treatment plant to the Company’s headquarters at E. Orzeszkowej 1 Street;
4. Implementation of a photovoltaic installation with a capacity of approximately 50kWp for the Legionów water intake;
- Construction of a building for technical and social needs of the treatment plant and composting facility along with garages;
- Replacement of the Dn150 water supply network in Konarskiego Street in Słupsk;
as well as the commencement of new tasks, including among others:
- Construction of the water supply network in Hubalczyków Street in Słupsk;
- Construction of the Dn250 sewerage network in Kaczmarskiego Street in Słupsk;
- Construction of the water supply and wastewater sewerage network for the residential area under the Local Spatial Development Plan (MPZP) “Gdańska V”;
- Construction of the water supply network in Batorego and Rybackiej Streets;
- Implementation of a backwash water recovery system at the Westerplatte Water Treatment Station – ULTRAFILTRATION.
In conclusion, despite the ongoing pandemic and related difficulties in implementing certain investments, the Company carried out its planned investment tasks in 2021, resulting from the need to expand or reconstruct the existing water supply and sewerage infrastructure to ensure continuity of water supply and wastewater discharge, as well as to optimize service delivery costs.
