Abstract:
Hulu Teso Village is a village that was awarded the construction of a dam in the past.
In the management of dams in the past as empowering fisheries, but no longer
functioned. Currently the dam is only used as a recreation area. Looking at the current
condition of the Dorian Sei Dam, it can be used more effectively as a source of clean
water or raw water reserves. This is because the village of Hulu Teso had experienced
a long dry season which resulted in water drought in the village community dug wells.
The purpose of this research is to plan the dimensions of water reservoirs from dam
runoff so that they can be a source of clean water supply for the community in Hulu
Teso Village. The research method used is qualitative and descriptive that is by
collecting population data and observing research locations and calculations based on
the 1996 Dirtjen PU Planning Planning Criteria. From the research results obtained
water needs for domestic and non-domestic as much as 251,371.44 liters. To meet the
water needs of the population, the volume of holding water must be greater than the
water requirement (QV> QTair) with dimensions of 7m x 3m x 13m, the amount of 273
m3 or 273,000 liters / day is obtained, the reservoir capacity is able to meet the water
needs of the population. To get clean water sources as raw water reserves, filtration is
carried out on dam runoff by making water filter buildings, so that water that enters
the reservoir can be used as a source of clean water.
