River water, surface water reservoir, raw water.

 

ABSTRACT

The soil in Sampang Regency has low water absorption capacity. This is due to the topsoil is dominated by clay soil, while the subsoil is weathered from limestone. As a result, rainwater tends to be surface runoff and difficult to absorb into the ground, thus the flood discharge is high. This condition makes Sampang Regency experience limited groundwater resources, so that raw water needs are more dependent on the river water (flood water). Samiran river, with its dam, is one of the major sources of raw water for the fulfillment of irrigation water, and for drinking water as well. The topography around the dam location makes the Samiran river potential for flood water reservoir. This study aimed to analyze the water quality in Samiran dam, as well as the volume of flood water that can be used as raw water. In general, the results of this study show that the water quality of Samiran dam was in accordance with the standards for raw water. In addition, the potential for flood water that can be used as raw water was 50 l/sec, to support water needs for 344 days.
