Phoenix V LLC dba BEI Hawai‘i $454,902.94 Bidder Amount Pural Water Specialty Co., Inc.$387,672.39 Contingency $ 62,327.61 $450,000.00 TOTAL CONTRACT PRICE: The estimated quantity of polymers needed for the 24-month period of the contract, as determined by the County, is 408,076.20 pounds, at $0.95 per pound. The reason for the high contingency is that due to past experiences, the dosage of polymers used at the time of the plant test is lower than at other times of the year. As the quality of water goes down during the year due to unstable weather conditions, more polymers are used to meet the water quality requirements of the State of Hawai‘i, Department of Health. The Manager-Chief Engineer recommended that the Board award the contract for WATER TREATMENT PROPOSAL NO. 2014-04, FURNISHING AND DELIVERING POLYMERS TO , WAIMEA WATER TREATMENT PLANT, to Pural Water Speciality Co., Inc. for the bid price of $387,672.39, plus $62,327.61 in contingency, for a total contract price of $450,000.00, and that either the Chairperson or the Vice-Chairperson be authorized to sign the contract(s), subject to review as to form and legality of the contract(s) by Corporation Counsel. The contract period is from July 1, 2014, to June 30, 2016. MOTION: Mr. Greenwell moved to approve; seconded by Mr. Takamine. Mr. Robinson asked what polymers are used for. The Manager-Chief Engineer said they are part of the water treatment process of raw water stored in Waimea. He confirmed that this was for treating surface water. Mr. Robinson asked if the surface water is filtered and the polymers assist in binding the material in the water. The Manager-Chief Engineer confirmed this; the polymers cause coagulation; the polymers help reduce the turbidity of the surface water. Mr. Ikeda said that the process is to clean up the water before it goes through the treatment plant. There are particles floating around in the raw surface water, so the chemicals (i.e., the polymers) are injected and mixed up to adhere to the particles. The resulting mass turns into sludge, and flows into the sludge basis for disposal. Mr. Uyeda asked if the polymers were in powder form or in solution form. Mr. Ikeda said the polymers are in solution form. Mr. Uyeda asked if they sell it in powder form for drinking water applications, as they do for waste water. Mr. Ikeda said he was not sure, but DWS’s Water Treatment Plant is set up for the liquid form of polymers. ACTION: Motion carried unanimously by voice vote. Page 4 of 27 Water Board Minutes 5-27-14 js
