Conventional fish hatchery has many challenges such as large land use, excessive water use, environmental pollution and a controlled maintenance system, making the fish hatchery process inefficient. The application of the development of the Controlled Water Recirculation System (SRAT) can be a solution to overcome this problem. This study aims to obtain a water balance model, and determine the amount of pressure loss that occurs in the SRAT piping network, in order to improve the performance of SRAT by maintaining the uniformity of water discharge in each water tank in the SRAT. At first, the average discharge was 2,134 L/min with a uniformity value of only 79%. After the intervention of the model, the uniformity value increased to 99% with an average of 1,869 L/min. It can be concluded that the model built can maintain the uniformity of water discharge in each tub contained in the SRAT
