Mining water is one of the main problems that has a great importance on mine productivity. In mining implementation, it is necessary to study the Mining Water (Hydrogeology) system to support a good mine design. The Mining Water drainage system is a method for making work sites in the mining area always dry. Prior to mining, hydrogeological analysis and rainwater management methods are carried out. Calculation of rainfall intensity using Gumbel Probability estimation and water capture area analysis obtained CA-1 Q = 915, 35, m3 / day CA-2 Q = 1149, CA-3 Q = 141116, 01CA-4 Q = 1407.89, the form of rainwater trapping channels in the form of trapezium and pump requirements in each catchment area of 1 (one) pump each.
