To make its facilities more climate-change resilient and ensure efficient water delivery even during disasters, the Cagayan de Oro City Water District has continuously upgraded its production facilities. COWD has replaced most of the vertical turbine pump assemblies of its production wells with a submersible type. In fact, two pump assemblies were replaced this month- Production Well No. 23 located in Tin-ao last March 11 & 12 and Production Well No. 4 located in Macasandig last March 3 & 4. Only five (5) pumps of COWD’s 26 production wells have yet to be replaced.
Submersible type pumps have both its motor and pump under water, and thus, are not easily affected when floods occur. With less movable parts, the new submersible type is also unlikely to be damaged than the old vertical turbine pump. If indeed it has to undergo repair, downtime is short and so is the period of water interruption. By 2018, all COWD existing pumps would have been replaced.
COWD also conducts well logging as part of its preventive maintenance. This process uses well logging camera to inspect the condition of the well. Both well casing and screen are checked for any obstructions and damage which may affect its discharge capacity. The result obtained from well logging will be the basis for remedial measures, if necessary. Thus, COWD always ensures the optimum operational efficiency of its production wells in order to serve the needs of the city’s water consumers.
