PERENCANAAN PEMANFAATAN RAINWATER HARVESTING (RWH) SEBAGAI ALTERNATIF SUMBER AIR Bersih (Studi Kasus Universitas Mercu Buana)
Daftar Isi:
- Due to the increase of the population, demand for clean water keeps on increasing. Up to this time, the source for clean water comes from ground water. Rainwater Harvesting becomes one of the alternatives to deal with problems of water scarcity. This research aims to investigate reliable rainfall, clean water necessities, the tank capacity of RWH, the impact of RWH uses, quality of rainwater, and effective rainwater treatment to improve the quality of rainwater that has not fulfilled the standard of clean water by using modified filter media activated carbon and zeolite. This research uses the quantitative descriptive method by collecting data, analyzing data and concluding the result of the research. The object of the research is Building D and E of Mercu Buana University. The rainwater was tested based on parameters including Temperature, TDS, pH, KMnO4, and Coliform. The filter media used to treat the rainwater is composed of zeolite and activated carbon (AC). The combination of the filter was 100% AC, 50% AC: 50% zeolite, and 100% zeolite. The results from rainwater analysis showed that the reliable rainwater from three water stations that has been reviewed, there is a need of 18,12m3 clean water per day for employee water needs, RWH tank capacity based on existing condition is 180m3. The use of RWH is capable of reducing well water use up to 35.82%. After processing, the quality of rain water in Building D and Building E of Mercu Buana University has already met the water quality standards for the purposes of sanitation hygiene, Permenkes Republic of Indonesia no. 32 2017. Media filter that is effective as rainwater filter is filter media with 100% zeolite. The quality of rainwater after processing was 26 ̊C (Temperature), 168 mg/L (TDS), 7,61 (pH), 5,2 mg/L (KMnO4), and 4,5 MPN/100 ml (Coliform). The system of RWH consisted of rainwater catch, distribution pipe with a diameter of 8”/216 mm, filtration tub measuring 2m in length, 1,6 in width, 0,8 in height, and RWH tub planned with a capacity of 180 m3. The RWH will be located in three locations in the back of Building D, the right side, the middle, and the left side of Building E in which each RWH will have a capacity of 60 m3. The size of RWH is 10m in length, 3m in width, and 2m in height. Filtration tub and RWH are planned to be made of concrete.
