Abstract

Batam City is the economic center of Riau Province with a predicted population of 1.8 million people in 2025. To support economic development, Batam City needs a reliable supply of raw water. Mukakuning and Duriangkang reservoirs, which are cascade reservoirs, are the largest contributors to raw water supply in Batam City. This study aims to determine the maximum capacity of the two reservoirs to meet current and future raw water demand. Discharge in the watershed is calculated using daily HEC-HMS model calibrated using Duriangkang Reservoir water level data. The storage of Mukakuning and Duriangkang Reservoir are 6.3 and 106.1 million m3 respectively, equivalent to 39% and 77% of the runoff volume of each watershed, classifying the two reservoirs in the multi-year category. Using current operation, the two reservoirs can supply up to 3.24 m3/s at 100% reliability, compared to existing capacity of 3.1 m3/s. The water loss is dominated by evaporation which reaches 32.6 million m3/year while spilled water is only 8.3 million m3/year. At 95% reliability, the reservoirs are almost at maximum capacity and able to supply 4.03 m3/s of raw water with the spilled water is only 0.4 million m3/year. Efforts to increase capacity by increasing normal water levels are not effective and lead to dam overtopping in PMF condition. More effective way to increase water supply can be obtained by changing operating patterns. If the reservoir is in dry condition, determined by predicted SPI, the water supply is limited so that the discharge can be utilized for a longer period.

Abstract

High rate of pollution on the watershed has impacted to deteriorate water quality reservoirs. Officially, Quality Status of Reservoir Ecosystem has not been established yet. So, this study describes the accomplishment of integrated watershed management using Quality Status of Lake Ecosystem criteria (SMED) formulated by ministry of environment. The application of the criteria to Saguling and Sutami reservoirs datas shows that quality status of the reservoir ecosystems are in threat conditions. In order to apply the SMED criteria for assessment of quality ecosystem in reservoir, the advance experiments are still needed mainly for the additional indicators as following: 1) integration blue­algae and biodiversity indicator with biodiversity index; 2) suitability of land erosion indicator connected with reservoir design of erosion rate; 3) shifting of siltation lake indicator siltation reservoir indicator in relation with the percentage of dead storage volume; 4) integration hydroelectric power and water resources exploitation associated with the hidrological reservoir and water balance; 5) suitability of fish cage calculation in reservoir, 6) suitability of water quality indicator related with water quality standard; 7) addition of corrosivity index and quality of bottom sediment in reservoir. To facilitate apply the SMED for the assessment of reservoir ecosystem.
