Wai'aha Deepwell History and Repair Status Information Sheet - 2017 <br /> <br />Department of Water Supply logo. <br /> <br />DEPARTMENT OF WATER SUPPLY, COUNTY OF HAWAI`I, <br />345 KEKŪANAŌ`A STREET , SUITE 20, HILO, HAWAI`I, 96720, TELEPHONE (808) 961-8050, FAX (808) 961-8657 <br /> <br />September 15, 2017 <br /> <br />WAI'AHA DEEPWELL HISTORY AND REPAIR STATUS INFORMATION SHEET. <br />Information Sheet. <br /> <br />Overview, <br />Wai'aha Deepwell consists of a pump and motor which can produce approximately 1,400 gallons per minute. The pumping unit <br />is housed in a 20” well casing, which is approximately 1,754 feet deep. The pump bowl diameter is 11-1/8” and the pump is <br />approximately 17 feet long. The motor is a 4-Pole, 700 horsepower, 4,160- volt submersible motor. The motor diameter is 11” <br />and it is approximately 17 feet long. <br /> <br />Prior History, <br />Designed and built in June 2006, Wai'aha Deepwell has undergone repair one (1) time prior to this current repair. <br /> <br />Current Repair Status, <br />Wai'aha Deepwell is currently undergoing repair. Contractor for this repair is Derrick’s Drilling and Pump Services, LLC. Repairs <br />include the replacement of the existing deepwell submersible pump and motor, power cable, column pipe, column couplings, and all <br />appurtenant materials, such as cable guards and strapping; appurtenant electrical work; and chlorination and testing of the well and <br />pumping assembly. Pump and motor were installed as of July 26, 2017. Upon startup on July 27, 2017 the motor tripped on over <br />current condition. Trouble-shooting indicated a problem “down-hole” so the contractor proceeded with extracting all of the column <br />pipes, pump and motor. On July 29, 2017, during extraction of the pump and motor, there was a failure in the lifting cable resulting in <br />the pump, motor, most of the column pipe, and the power cable falling into the well. The contractor is working to remove the pump <br />and motor from the well. If removal is successful, the well will need to be inspected for any damages. The pump, motor, column pipe, <br />and power cable will need to be replaced to prevent an unknown weakened component causing a failure in the future. At this time, the <br />schedule for this well repair is unknown. <br /> <br />Water Restriction Information, <br />An Emergency Water Restriction is in effect as of August 13, 2017.
