Abstract

The purpose of this study was to survey Suwon citizens over the age of 20 in order to provide basic data on the extent of coverage of the city's water reclamation system and to set guidelines for a policy on water reuse. The survey used a questionnaire with two fields, rainwater use and wastewater recycling, for analyzing factors that influenced water reuse. A factor analysis of 19 questionnaires gave a Cronbach's alpha coefficient greater than 0.4. Factors that influenced rainwater use were environmental protection, water charges, and the risk of climate change. Of the total explanatory power, the share of rainwater use and environmental protection was 39.7% and 28.1% respectively. Environmental protection (explanatory power 24.2%) had an effect on the explanatory power of wastewater reuse. When factors influencing wastewater recycling, like cost of recycling, water management policy, climate change, and suspension of tap water supply were included, the explanatory power of each of these factors went up by 4.3%, 2.8%, 3.3%, and 1.1%, respectively. For more effective wastewater recycling, a water management policy that factors in the above is required, along with a campaign to educate citizens on water management and environment conservation. Additionally, it may be necessary to improve the reliability and the quality of water supply.

본 연구는 물재이용 활성화 방안 및 물재이용 정책시행을 위한 기초적인 자료로 제시하기 위해 20세 이상의 수원시민을 대상으로 설문조사하였다. 설문지는 시민들의 물재이용 결정요인을 분석하기 위해 빗물 재이용과 하수처리수 재이용 2개 분야로 구성하였다. 물재이용 결정요인은 요인분석을 실시하여 요인의 신뢰도 Cronbach's Alpha 값이 0.4 이상으로 나타난 19 문항을 이용하였다. 빗물 이용에 영향을 미치는 요인은 환경보호, 수도요금, 단수위험 및 기후변화로 나타났다. 빗물 이용에 관한 모든 변수들의 총 설명력은 39.7%이며 환경보호는 28.1%의 설명력을 보였다. 하수처리수 재이용에 영향을 미치는 요인으로 가장 먼저 환경보호 요인이 투입되었으며 설명력은 24.2%였다. 하수처리수 재이용 결정요인에 수도요금, 물관리 정책, 기후 변화 및 단수위험이 추가적으로 투입된 결과, 각각의 설명력이 4.3%, 2.8%, 3.3%, 1.1% 증가되었다. 따라서 물 재이용을 활성화하기 위해서는 물재이용 정책 개발뿐만 아니라 환경보호에 관한 교육과 재이용수의 수질에 대한 신뢰도 향상이 중요한 요인이라고 생각된다.
