Feasibility Study for the Project: Rehabilitation of Communal Infrastructure Facilities in Batumi
Country: Georgia
Batumi, the fourth largest city in Georgia, is the capital of the autonomous Republic of Adjara. The water supply situation was unsatisfactory with per capita production rates of 900l/c,d, necessary to cover the demand including losses. The existing sewer system was also in poor condition and a source of serious contamination during regular flooding events.
The aim of the feasibility study was to ensure that the envisaged investments were directed towards the most urgent issues and used most efficiently. The study included first an assessment phase regarding water supply services, wastewater disposal, economic and institutional performance of the water utility, and economic capacity, as well as the needs on the side of consumers. To assess the socio-economic base parameters of the consumers, a household survey was conducted. The water supply system was assessed by hydraulic modelling, with leak detection and flow and pressure measurement campaigns carried out. The sewer system was assessed by manhole inspection and CCTV.
