Water reuse plays significant role in water saving and water environmental protection, and it helps alleviate the shortage of water resources. China's water reuse was put into practice since 1980s by means of pilot and promotion in National Fifth-year Plan and other strategies. The effects of water reuse is beneficial in both economic, social and environmental aspects. But some shortcomings still undermine future development of water reuse in China. To overcome and boost water reuse, Ministry of Water Resources conducted a successive survey across China. The aim of this study is to demonstrate the current condition of water reuse in China in construction, funds, legislation, planning, policy aspects, to summarize problems and its reasons underneath, to make suggestions for further development. Basically, in 2010, China's water reuse is 2.83 billion cubic meters and the utilization rate is 10.35%. Water reuse in China has four major characteristics: the first one is water reuse differences in amount occur national-widely and North of China has the main percentage as 47.3%; the second one is water reuse is mainly in environment maintenance (42.1%) and industry cooling (29.8%); the third one is funds for water reuse station and pipe construction is main in non-fiscal budget which take percentage as 56.8%; the fourth one is progresses of administrative system, political system, price management, standard system and technologies go rapidly recently. The problems of water reuse such as lack in water reuse station, delay in pipe constriction and limits on water reuse amount still exist due to some reasons. As a think tank of Ministry of Water Resources, we give some suggestions: firstly, water reuse needs to be integrated with traditional water resources allocation; secondly, public budgets need to be strengthened and income mechanism should also be constructed; thirdly, water resources integrated administrative of city and county should be boosted and roles as water reuse need to be clear and precise; fourthly, national, provincial and regional water reuse planning should be made in time; fifthly, regulations on water reuse should be programmed as soon as possible.

본 연구는 물 재이용 연구개발 지원 및 물 재이용 활성화 정책 인식에 관한 영향관계를 검증하였다. 연구결과 물 재이용의 중요성 및 효과성을 높게 인식할수록 물 재이용 활성화 정책 필요성, 물 재이용 절수제품 사업체 지원 필요성 및 물 재이용 정부 투자 필요성을 높게 인식하는 유의한 영향관계가 나타났다(p<.001). 또한 남성일수록, 학력이 높을수록, 사무 단순노무 종사자보다 관리자 전문가 판매 및 기능 종사자일수록, 빌라보다 주택 거주자일수록, 월평균 수도요금이 4만원대 이상일수록 물 재이용 정책의 필요성을 높게 인식하는 경향을 보였다. 본 연구는 물 재이용 연구지원의 중요성 및 효과성 인식이 물 재이용 정책 필요성 인식에 미치는 영향을 분석함으로써 물 재이용 활성화를 위한 적극적인 투자 및 지원정책 마련에 근거를 제시한 데 그 의의가 있다.

An water-reuse network design has drawn attention as a systematic method of reducing fresh water usage and increasing water-using efficiency. The final goal of an eco-industrial park(EIP) is accomplishing industrial sustainability and constructing water-reuse network can be a solution. When designing water-reuse network connecting various processes which consume water, the water pinch technology can be used frequently, since it simultaneously minimize freshwater usage and wastewater discharge. In this research water pinch technology is applied to develop an effective water-reuse network in an EIP. Three scenarios based on different reusing strategies were developed. The results show that the final water-reuse network can reduce the total fresh water usage more than 30%, while the water expenses decrease by 20%. It can be concluded that water pinch technology is an effective tool to optimize water-reuse network among different industrial facilities.

Water cycle analysis was performed for Gunja basin located in metropolitan Seoul using Aquacycle model in order to assess the problems of urban water cycle. From the water cycle analysis of Gunja basin, it was found that 75% of total rainfall occurred in the form of surface runoff, and groundwater recharge only accounted for about 7%. This suggests serious distortion of water cycle which can be attributed to urbanization. Feasibility analysis of reuse scenarios such as rainwater use and wastewater reuse was then performed to examine their influences on improving the water cycle. From the analysis of water reuse options, it was shown that imported water supply savings of 13% can be achieved through rainwater use, and water supply savings of 31% through wastewater reuse.

Reuse of wastewater will intensify in the coming decades due to water shortage, the change of climatic conditions, the need for industrial and agricultural use and the necessity of improving health and environmental conditions for the growing population. This paper considers (a) the status and trends of wastewater reuse and reclamation in the world, (b) case studies of wastewater reuse projects, (c) analysis of technology level, (d) forecast of global market, and (e) the future views and directions in development of wastewater reuse technologies. Based on the available documented literature, this paper provides a review assessment of the current status of the wastewater treatment processes including potential applications for reuse. Key challenges for both wastewater treatment and reuse are also discussed in the paper and include recommendations, e.g. cost, effluent water quality, energy use and technical solutions, for future developments.

As an alternative water resources development, wastewater reuse for agricultural and instream uses are expected to be fond of the limelight. In order to find the feasible reuse system scheme for reclaimed water in real field, existing reuse sites were investigated for water quantity, quality, and irrigation scheme. From the results, most of sites supplied reclaimed water with a request of the users(farmers) and reuse techniques for agricultural use were to be needed in the sites which supplied over yearly $1.0{\times}10^6$ ton as agricultural water.

최근 물 사용량의 증가와 잦은 가뭄 발생으로 인해 물 부족 현상이 심화되고 있다. 따라서 기존 취수원에 대한 의존도를 줄이고 버려졌던 물의 재이용을 활성화하여 친환경적이며 지속가능한 대체수원을 확보할 필요성이 부각되고 있다. 국내에서 활용가능한 물 재이용 방법은 빗물재이용, 중수 재이용 및 하수재이용 등 크게 세 가지로 구분할 수 있으나, 아직 국내에는 물 재이용이 활발하게 추진되고 있지 않다. 본 연구에서는 세 가지 물 재이용 방안 중 연중 발생량이 일정하고 이용가능 수량이 많으며, 수질이 비교적 양호한 하수재이용수의 활용방안을 모색하였다. 적용대상 지역으로 선정한 용인시는 총 26곳의 골프장이 운영 중에 있으며 이는 전국에서 운영 중인 골프장의 약 10%에 해당한다. 골프장은 시설 운영을 위해 많은 양의 용수를 소비하는 대규모 수요처이므로 재이용수를 활용한다면 큰 경제적, 사회 환경적 편익을 얻을 수 있을 것이다. 본 연구에서는 용인시를 대상으로 하수처리장 인근에 위치한 골프장 내 조경용수로 하수재이용수를 활용하였을 경우의 경제적 효과를 비용 및 편익 추정을 통해 분석하였다.

In this study, It classified type of irrigation water development in islands district. As result, the types which were type of reservior, fleshwater lake, pumped storage, ets. Most of islands district has developed reuse irrigation system as a pumped storage system. But, Irrigation water-reuse ratio doesn't define a basis clearly and the value of measurement for water-reuse ratio doesn't exist so far. so, we measured Irrigation water-reuse to clarify for water-reuse ratio in a pumped storage system.

In this study, Types of irrigation water development in islands district were classified. The types were reservior, fleshwater lake, pumped storage, etc. Most of islands district has delveloped reuse irrigation system as a pumped storage system. But. Irrigation water-reuse ratio doesn't define a basis clearly and the value of measurement for water-reuse ratio doesn't exist so far. so, we measured Irrigation water-reuse to clarify for water-reuse ratio in a pumped storage system. Also, we need to develop hydrologic analysis and water balance method with characteristic factor of islands district. that make use of plan about security of agriculture water efficiently in islands district.
