Abstract:The Unesa Ketintang Campus in Surabaya City is in lowland with an altitude between 3-4 m above sea level. Every rainy season arrives in this area frequent flooding. Puddles that occurred in 2013 with a long pool of ± 4 hours. Efforts have been made in 2014 to tackle flooding by raising paving pairs in open fields and roads and making reservoirs of ± 0.6 ha in the Unesa Ketintang Campus environment, normalizing the channel and installing pump houses to support the process of accelerating the reduction of standi… Show more
“…The test data results and measuring instrument reading instrument readings are presented in table 2 of the results of the total head calculation using equation (5). To protect against overpressure, install a pressure relief valve at the bottom of the pump head.…”

Even the pump house guards or workers must be on standby in dealing with this hydrometeorological disaster. One of them is the existence of flood prevention infrastructure such as pump houses. Pumps have to accelerate water transfer from puddles to the sea or river. A reliable standard pump can suck 1,5 m3/second. Very different from the current condition of the pump house, after being surveyed and inspected, its suction capacity is only 0,5 m3/second. The research method used to restore pump performance uses the ISMO (inspection, minor repair, medium repair overhaul) maintenance method. It is necessary to identify the damage to the pump and carry out maintenance of all components that have less than-optimal functions. The results of the maintenance implementation stage and the inspection results require periodic cleaning, repairs to the nearest drainage filter and a setting on the pump. At the same time, the overhaul activity is carried out by dismantling the installation's shaft, bearing, and impaler components. In contrast, the discharge nozzle requires setting the fluid pressure to increase to 1,3 m3/second.
