The study was conducted at the PSAU Nursery from November 2019 to March 2020 to design, fabricate and evaluate the discharge and efficiency of the ram pump. A ram pump is a mechanical water pumping device that uses gravity or the downward movement of water from a higher elevation towards a lower elevation. It lifts a lesser amount of water to a higher elevation than the source. The study obtained a highly significant result where in the head of the ram pump was established at 3 meters with a discharge value of 0.688 liters per minute. The water was collected using two 250 liters drum which can be filled for 12.11 hours. The efficiency of the ram pump is 55.25%, The payback period of the pump is 5.65 years or 2062.25 in days and can be operated everyday and breakeven volume is 314.68 m'. The initial cost of the pump is Php8,626 with an annual net income of Php1,374.62. The pump is economically feasible because it obtained a return of investment of 15.94%.
