The need to irrigate farms/gardens by a method that will replace the natural rainfall when not available led to the design and construction of the sprinkler irrigation system. In this study, a sprinkler irrigation system was designed, constructed and installed. The design was based on using a rotating sprinkler system to irrigate a small size plot which provides an acceptable scientific basis for proper water scheduling, evaluation of the system and minimizing water wastage and runoff. It was designed for four crops, but tomato (Lycopersicum esculentum spp) was considered with irrigation interval of five days. The result shows that the discharge of individual sprinkler was found to be 2.144 lit/sec and the rate of application of the sprinkler was 8.85 mm/hr, the pump required for the operation of the system is approximately 2 hp and a pressure at the inlet of the main pipe is 13.44 bar.
