Abstract

Manggar reservoirs located in the Village Karangjoang District of North Balikpapan is a major water sourcewith 900 lt/sec. Water quality status of Maggar Reservoir in 2013 showed in heavy polluted condition (BLHBalikpapan, 2013). Water quality measured remains fluctuate where a water quality decline to 4th. To find themain pollution, required the pollutant sources analysis and water capacity of Manggar Reservoir. Sources ofpollution can be natural or anthropogenic. The study used quantitative methods are corroborated by qualitativeanalysis. Debit calculation using rainfall Peanman conversion approach, the analysis capacity of the reservoirusing a guide Minister Of Environmental No. 28 of 2009. The critical peak flow inlet in August at 2.8 m3/sec.While the peak on dry season occurs in August, September and October. The dominant pollution load caused bynatural sources podzolic soil that is acidic and dissolves the high levels of iron in the rocks. This causes afluctuate decrease of oxygen dissolved. While the burden of pollution from human activities is still very smallcompared to the power of purification reservoirs. Water quality reservoir capacity are remain good and on level1. There is a significant effect of the wet and dry conditions on water quality. In the wet season, reservoir waterquality tends to have low oxygen dissolved and high Fe.

Abstract

One of the MDGs is to increase peoples access to clean water. Population growth and lifestyle needs ofwater cause Semarang rate increased rapidly while the coverage of drinking water Semarang limited (59%).By 2015 the MDG target 75% of the needs of the average supply of water about 3,442 l / s, and in 2030 ittakes 4,727 l / s at the 100% level of service. Condition of existing water sources either from the RiverGarang, ABT, baboons river continuity and quality of the constrained problem. Klambu- Kudu Channel havea channel-leakage problems is high that the discharge was not obtained in accordance with the initial designplanning. Supply conditions groundwater becoming increasingly declining so it needs a replacement sourceof water supply. Scenario SPAM Semarang to meet increasing Water Supply, described in Short-Term policy(75%) according to the MDGs in 2015, 2020 Medium Term (85%) and Long Term Semarang in 2030(100%). Development of water supply are key to SPAM derived from West Semarang Reservoir operatedJatibarang 2015 Phase I (Q = 500 LPS) and phase II in 2020 (Q = 1000Lps). In addition, there is apotential supply of river Blorong supply of 200 l / s and scout the river of 300 l / sec.
