It is proposed to improve the waste water system in Gudauri under the Asian Development Bank (ADB) funded Urban Services Improvement Investment Program, which is under preparation stage. This Investment Program, implemented in secondary towns of Georgia, will develop the water and sanitation services, which will improve quality of life and optimize the social and economic development. Ministry of Regional Development and Infrastructure (MoRDI) is the Executing Agency (EA) and United Water Supply Company of Georgia (UWSCG) is the Implementing Agency (IA) of this Program. This subproject will be implemented from 2018 to 2020. All environmental impacts associated with the works are minor and can be managed through effective implementation of an environmental management plan. Since the subproject is unlikely to have significant adverse impacts, it is classified as environment Category B, and accordingly an Initial Environmental Examination has been conducted. This is a summary of the IEE Report. 2. The Investment Program will improve water supply and sanitation (WSS) services in secondary towns of Georgia. The Investment Program includes (i) infrastructure improvement to rehabilitate, improve, and expand WSS services; (ii) institutional effectiveness to improve the service utility's technical and management capabilities of the key WSS service provider, United Water Supply Company of Georgia LLC (UWSCG) to provide efficient WSS services, and develop the capacity of sector regulators to regulate tariffs, services standards, environmental protection, and drinking water quality in the long-term; and (iii) Investment Program implementation support. 3. The scope of work under the consultancy services is to (i) assess the technical, financial, economic, and environmental feasibility of subprojects; (ii) conduct surveys and investigations; (iii) develop hydraulic models; and (iv) prepare detailed designs, drawings, cost estimates, specifications, and bid documents for implementing water supply and sanitation schemes in the Investment Program financed by the MFF. 4. The present IEE document: “Improvement of Gudauri Waste Water System” describes the expected environmental impacts of the sub-project implementation and gives the developed relevant mitigation measures to avoid, mitigate and/or manage such impacts. The present document covers both, construction and operation stages. 5. 5. Gudauri is a ski resort located on the south-facing plateau of the Greater Caucasus Mountain Range in Georgia. The resort is situated in the Stepantsminda District, along the Georgian Military Highway near the Cross Pass, at an elevation of 2,200 meters (7,200 ft.) above sea level with skiable area enjoying maximum exposure to the sun. Gudauri lies 120 km (75 mi) to the North of the capital Tbilisi.
