PENGEMBANGAN DAN PEMANFAATAN MATA AIR YEH HA UNTUK SISTEM PENYEDIAAN AIR MINUM (SPAM) DI DESA SERAYA KABUPATEN KARANGASEM
Abstract: Seraya Village
consist of West Seraya, Central Seraya and East Seraya. Central Seraya, East
Seraya and Bunutan Village. They are well known as the village with lack of
water supply. Therefore, a planning of water supply system is required to
fulfill the optimum level of service. The planning of water distribution
network is derived from Yeh Ha spring water, which is located in Abang
District. Yeh Ha spring water is located in a high altitude (369 meter above
sea level) so that gravity system is required in the planning of water
distribution network. Based on data in RISPAM (Master Plan of Potable Water
System) of Karangasem regency, Yeh Ha spring water capacity is about 330
liter/sec while the existing demand are used to irrigation system for 50 Ha
irrigation area. Meanwhile, 20 liters/sec of amounted is used as drinking
water. The analysis of drinking water demand to calculate reservoir capacity is
between 15 – 20 % from maximum demand while the hydraulic analysis of
transmission pipes is computed by Waternet software. Furthermore, water demand
projection can be projected for 20 years ahead to determinethe capacity of
water needs for three villages such as Seraya Tengah village, Seraya Timur
Village and Bunutan village. Based on Waternet simulation program, the pipes
system generated a huge relative energy which is reached 18 bar. Based on the
result of relative energy, quality of the pipes can be defined. Water pipes
system on the site plan is using galvanized iron, which has a diameter between
0.4 meters and 0.7 meters long and it is only used for the transmission pipe to
reservoir. This pipeline network used gravity system only.
