Owing to the rapid development of industrial activity and urbanization of our country in recent years, and in order to make full use of water resources, and having assessed the major rivers flow， tributaries flow, water bodies, water quality, population number and the water using structure of resident, the Environmental Protection Department delineated and announced the uses of water zone year by year. Due to river change, in order to re-assess water contamination extent and re-plan the water area of the scope, purpose, and draw the future river water zones set up standard operating process, it commissioned "to promote water area delineation plan (Southern District)" (hereinafter referred to as the program). The extent of the plan contains：(1) the completion of draft of the notice of the delineation of the 13 counties (cities) river water body , (2) survey and estimate the water pollution sources and the amount of pollution, (3)develop the improvement strategies of impaired water quality，and (4) review the adjustment the range of the water zones and announcement matters. The work content which have completed , aimed at the 13 not delineated river, through expert consultation meeting ,to establish water area delineated standard operating procedures and the delineation principle, to collect and analysis the basic data of Water Zones, to handle 13 session of the site operations performances to inspect the river, to establish the draft of the notice of the water body for the 13 rivers and to assess the items of impaired water quality for river body ,to establish the pollution dredge strategy of impaired part of river, to collect and suggest the guide to improve the water quality for impaired rivers , to be the publicity material to popularize policy and to be the tool to educate and train the environmental members , and handle one session of lecture and study for “guide to improve the water quality for damaging river “, and invite the industry competent authority ,the using units of water body , the related member of environmental protection for other industry ,the teacher and student of research organization or university ,or the interest for water body improvement. And for 16 rivers which already declined by central authority and counties, analysis its flow rate, water quality, use, present land use situation, and propose proposals to review and adjust. This project also integrate information which the water zone are delineated by, includes: the river classification case, water system distribution, location of water intake station, the water area , the site situation to inspect and pollution sources, and to build management system available for overlay and display, to assist the authorities to analysis and make decision for the river water body classification, to inspect the site operations and to promote public understanding the range of the water zone division.
