The subject-matter of the contract is the performance of an investment task – the execution of works entitled: ‘Construction of the Municipal Sewage Treatment Plant in Świecie’. Currently, municipal wastewater from the City and Commune of Świecie and the Commune of Bukowiec through the sanitary and combined sewage system and the pumping station network are directed through the speed extinguishing chamber to the Mechanical Municipal Wastewater Treatment Plant, where they are pre-treated with floating parts and sand. They are then sent to an industrial waste water treatment plant, the MONDI Sp. z o.o. cellulose plant, where they are subject to further treatment. The purpose of this project is to build a waste water treatment plant exclusively for urban waste water. For this purpose, it is planned to carry out renovation / modernization of existing facilities and construction of a biological, sedimentary, biogas part with accompanying infrastructure and a sewage duct cleaned from the outlet to the Wda River. After the implementation of this investment, the sewage treatment plant will include the following technological facilities: 1) Sewage part (mechanical and biological treatment): (a) Speed extinguishing chamber locked with separation chamber — ob. 01 – upgraded, b) Mechanical waste water treatment building – ref. 02 – upgraded, c) Sewage pumping station – ref. 03 – upgraded, (d) Feeder station – 04 – designed, (e) Pre-settlers – ob. 05.1, 05.2 – designed, f) Initial/retention settling facility – ob. 06 – designed, g) PIX tank – ob. 07 – Designed, h) Biological reactor – ob. 08 and 09 – Designed, i) Secondary sedimentation plants – ref. 10.1, 10.2, 10.3, 10.4 – projected, j) Pumping and blower building – ob. 11 – Designed, k) Process water tank – ob. 12 – Designed, (l) Sheep and pre-sludge tank – ob. 13 – Designed, m) Reservoir of treated waste water – ob. 14 – proposed. 2) Sedimentary part: a) Excess sludge gravitational thickeners – ob. 15.1, 15.2 – designed, (b) Fermented sludge tank/pre-sludge thickener – ob. 16 – Designed, (c) Odorous air biofilter – ob. 17 – planned, d) Drainage building – ob. 19 – Designed, (e) Dehydrated sludge shed – ref. 20 – projected, f) Lime silo – ob. 21 – planned, g) Operational building – ob.26 – planned. 3) Biogas part: a) Separate Fermentation Chamber (WKFz) – ob.22 – projected, b) Biogas torch – ob.23 – projected, c) Distribution and measurement node – ob.24 – projected, d) Desulphurisation station – ob.25 – projected, e) Biogas tank – ob.30 – projected, f) Inter-object networks with: dehumidification module – ob.B.01, siloxane reduction filters – ob.B.02. the necessary armament and wells 4) Accompanying facilities: a) Trafostation – ob.18 – projected, b) Energy and heat building – ob.27 – projected, c) Administration and social building – ob.29 – projected, d) Place and manoeuvring paths, e) Interfacility networks with the necessary equipment, valve chambers and wells, f) Pipeline discharging wastewater into the Wda river. 4.5 Order names and codes according to the Common Procurement Vocabulary: 45252127-4 Waste water treatment plant construction work; 45100000-8 Site preparation; 45111300-1 Demolition works; 45200000-0 Construction work for complete construction works; 45300000-0 Construction installation work; 45311000-0 Wiring and electrical wiring works; 45331210-1 Ventilation installations; 45400000-0 Finishing works for construction works; 45310000-3 Electrical installation works; 45233140-3 Road works; 45252200-0 Sewage treatment plant equipment; 45262310-7 Rebar work; 45262311-4 Concrete and reinforced concrete works; 45223100-7 Installation of metal structures; 45262500-6 Masonry and masonry work; 45332000-3 Plumbing works; 45231300-8 Construction of waterworks and sewage pipelines.
