ABSTRACT The groundwater and water works development at Phaluay Island, Surat Thani Province, is part of the Community Development with Clean Energy, a project which the Department of Groundwater Resources has participated with a goal to identify potentiality of groundwater development to supply the infrastructure development of the Island. Exploration, potentiality assessment and development of groundwater are handled by the Department of Groundwater Resources including the Groundwater Exploration and Assessment Bureau, Groundwater Development Bureau, Groundwater Resources Regional Center 1 (Lampang) and Groundwater Resources Regional Center 6 (Trang). The fieldwork includes 170 geophysical shotpoints producing 4 crosssections of 2D subsurface geophysical interpretation, 12 exploratory wells of which 3 are dry, wireline data from 10 wells, well test data from 9 wells, water sample collection from 9 wells for water quality analysis, geographical leveling, investigation and design of the groundwater works. From the preliminary investigation, there are 9 wells capable of producing good quality groundwater at a rate ranging from 1 to 5.5 cubic meters per hour, sufficient to develop a groundwater works. The ultimate system yield is up to 80,000 liters a day, sufficient to respond the need of 500 population of 4 bay areas of Phaluay Island. The project not only helps resolve inadequacy issue of water supply for consumption on Phaluay Island, but it also proves the concept of total approach and effectiveness of the methodology and budget management.
