Abstract
This study aimed to investigate the quality of the rooftop rainwater harvesting (RRWH) and to treat it for clean water supply alternative of Graha Rektorat building at State University of Malang, Indonesia. Different combinations of zeolite and activated carbon were used as filter media to treat the RRWH. Several parameters have tested to investigate the quality of RRWH based on Permenkes RI No. 416 / MENKES / PER / IX / 1990. Most of the quality of the RRWH met clean water and drinking water standard. However, there were three parameters have to be reduced and required further treatment. The results showed T4 reduced TDS and coliform bacteria by 37% and 36%, while T5 eliminated organic substances (KMnO4) for 35%.
Highlights
Increasing urban population has influenced the high demand for clean water consumption
Implementation of rooftop rainwater harvesting (RRWH) can reduce the use of water consumption that supplied by PDAM
The physical, chemical, and biological characteristics results of untreated RRWH were compared to the Indonesian standard for clean water quality control (Permenkes RI No 416 / MENKES / IX / 1990) (Table 3)
Summary
Increasing urban population has influenced the high demand for clean water consumption. It affects the increase in water demand and the quality and quantity of water sources in urban areas [1]. Due to a limited quantity of clean water that can be supplied by PDAM Malang and an escalation of the urban population, the optimum clean water distribution become a crucial problem. Implementation of RRWH can reduce the use of water consumption that supplied by PDAM. The use of RWH for homes, shops, apartments and buildings in Malang city decreased the water consumption by 30-40% [3]
