The City of Lviv is the 7th largest city in Ukraine with a population of roughly 800,000 inhabitants, situated in the north-western part of Ukraine. The Company operates 1100 km of water networks, 17 water intakes located at the distances of 10 to 105 km from the City, and two WWTPs, which are located at each bank of the Poltva River (Baltic Sea basin) in the north-eastern part of the City. Both WWTPs provide the complete biological wastewater treatment with a total capacity of 490 thousand m3 per day (140 and 350 thousand m3 respectively) and working capacity of 460 thousand m3 per day servicing 760 thousand connected residential users and all the industrial companies located in the City. The WWTPs occupy the territory of 111 hectares. The total length of sewerage networks and collectors is 639.4 km, 185.5 km of which are dilapidated and fully amortised. The WWTPs were constructed in the 1960-70s, and the equipment is old and worn out apart from the equipment that was installed through the World Bank project and SIDA grant funding.
The overall objectives of the project are (i) to achieve significant energy savings through use of biogas received as a result of sludge digestion process for combined production of electricity and heat; (ii) improve sustainability of the Company operations; (iii) achieve reductions in greenhouse gas emissions; (iv) reduce volume of sludge with corresponding positive effect on the environment; and (v) improve quality of wastewater going through Poland to the Baltic Sea basin (ensuring that the load to the Baltic Sea is not increased due to the internal load to WWTP resulting from digesters).
The Project will have a significant demonstration effect in the region serving as an example of the introduction of innovative energy efficiency solutions with high environmental benefits.
