was established following an order No. 11/13 of the Ministry of Economic Development of Georgia
under Georgian Commercial Law on 14 January 2010, by merging the two regional water companies West
Water LLC and East Water LLC. With the merger, the UWSCG took over the assets of its predecessors.
UWSCG is 100% state-owned, where the share is held by the Ministry of Infrastructure and Regional
Development of Georgia. Amongst the water-related competencies of the Ministry are: coordination
and support for the development of water systems in Georgia; coordination of regional programs
funded by national and international sources and oversight of their implementation; support and
coordination of international/trans-boundary cooperation of Georgian regions and local self-
governance units.
2. It is intended that part of the proceeds of the ADB loan mentioned above will be applied
towards the cost of Consulting services for Construction/Rehabilitation Supervision of the
following contracts:
