Abstract

Home residence around Bantan Tua Village, Batan Subdistrict, Bengkalis District, Riau Province, have a tub for Rain Water Harvesting (PPAH), to collect and store water when rain come for cooking and drinking purposes. PPAH tub at home residence has a variety of sizes. There is a tub that size is too large and too small. PPAH tub volume size must be adapted to the rainfall data to be able need supply for community. The fundamental problem is that most people do not know the effective size PPAH tub to accommodate the abundance of rainfall harvesting because limited rainfall data information and the using of formulas hydrology calculation. Based on rainfall data in Bengkalis 2014, the average runoff of rain water per month is 141.5 mm. Houses the size of 8 x 10 m, which is the dominant type of house in Bengkalis, the ideal amount of rainwater collected in each house is 1920 m2 / month. While water demand required by equating averaged, the house is a consisting of four members is 3600m3 / month. End of month, volume of tub has deficiency is 1600m3. Recommendation of effective PPAH tube is 1500 liters, based on data rainwater runoff per month.

Abstract

Disproportion between supply and demand of clean water is a complex problem in water management, especially in the coastal of Bengkalis city. Water scarcity occurs in different parts of the region accompanied by bad quality of ground water. Therefore, it is necessary to study the potential of groundwater as clean water and drinking water using geochemistry approach. Groundwater samples obtained from wells and wells drilled in Bantan Tua village, Bengkalis district, Riau. Most groundwater samples did not meet the requirements of clean water and drinking water based on Permenkes 492/Menkes/Per/IV/2010 in terms of physical and chemical parameters with temperatures ranging from 26-29oC, turbidity 5- >100 NTU, TDS 0-30,5 mg/L, pH 4,05–7,40, Cd 0,001-0,011 mg/L, Mn 0,020–1,775 mg/L, Fe 0,291–17,100 mg/L, Cu 0,000–0,095 mg/L, Cr < 0,05 mg/L, hardness 19,669–560,184 mg/L, SO42- < 25 mg/L, NO3- 17,96–220,6 mg/L, NH4+ 0,00–3,21 mg/L, F- < 0,10– 0,13 mg/L dan Cl- 0,2–71,8 mg/ L. The  groundwater in this study was dominated by non carbonate in form of  Na+K indicates that the facies of groundwater aquifers was influenced by seawater with clay lithology and illite mineralogy. The genesis of origin rocks derived from weathering igneous rock which rich in plagioclase and feldspar minerals.
