Montenegro – Wastewater treatment plant construction work – Construction of the wastewater treatment plant, wastewater collection system and implementation of water supply priority measures in the Municipality of Kolašin

The indicative scope of works covers the following elements: 1. Sewerage network: Construction of sewerage network in the approximate length of 9.2 km which will serve to 3000 inhabitants in the following settlements: Kolašin city centre, Braće Vujisić (Dulovina), Breza and partly Smailagića Polje and Gornji Pažanj. 2. Water supply priority measures: Water supply priority measures include services, supplies and construction works to be designed, supplied, installed and constructed by the Contractor. - Preparatory services (operational GIS, HID based hydraulic model, leakage detection for 30 km of network and detailed design of new elements including SCADA) - Supply, installation and commissioning of bulk flowmeters, and water meters (400), establishment of DMAs and SCADA - Works for upgrade of the water distribution system hydraulic configuration. 3. Wastewater Treatment Plant Design and Construction of WWTP in Bakovići settlement - Conventional Activated Sludge Process and aerobic sludge stabilization. Design and construction of the WWTP shall include two phases: Phase I - 4000 PE (to be constructed): Wastewater flowrate (including infiltration) = 765 m³/d (9 l/s); Peak dry weather flow = 57 m³/h (16 l/s); Peak wet weather flow to =109 m³/h. Phase II - additional 2000 PE (to be considered in design): Wastewater flowrate (including infiltration= 1045 m³/d (12 l/s); Peak dry weather flow = 77 m³/h (21 l/s); Peak wet weather flow = 150 m³/h The proposed process for WWTP includes: Influent pipe and by-pass line, inlet chamber, Coarse screens, Fine screens, Aerated grit chamber, Distribution chamber, Primary sedimentation, activated sludge and secondary sedimentation (biological) treatment, Effluent control and measurement chamber, Discharge line to the Tara River, Sludge pumping station, Sludge distribution chamber, Sludge thickener, Sludge reed beds, Drainage pumping station, Building for guard, laboratory, blowers, warehouse, Odour control, Plant infrastructure,...
