Colton Utility Authority Resin Pre -Purchase for Well Nos. 15/17 and 24 July 28, 2003 Page 2 of 2 associated with the regenerable brine type of system. The single pass resin also eliminates concerns regarding the future availability and potential increased costs of brine disposal. Although the Basin Water Technology proposal has a lower per -acre-foot cost, it would take 22.9 years of operation at 1000 AF annually to break even with the proposal provided by U.S. Filter due to the significantly higher initial capital cost. Thus, US Filter was selected at the vendor to provide the equipment and resin service for the treatment plants. The City is eligible to purchase spare resin as a part of the Proposition 50 grant for the project. As such, staff recommends that the CUA authorize the purchase of resin to treat approximately 1,500 acre-feet of water. The cost for resin and service at Well 15/17 is $237.62 per acre-foot of water treated. The cost for Well 24 is $197.47 per acre-foot of water treated. The total cost for the pre -purchased resin and service is $564,000. The pre -purchase of resin allows the City to maximize the utilization of the Proposition 50 Grant funding. This will be accomplished at no cost to the City of Colton water customer. If the resin is not purchased under the Proposition 50 project, the funds to treat the water will need to come from another source, e.g. RWQCB, City Water Operations Account, etc. FINANCIAL IMPACT Funds are available in the Water Capital Equipment Account Number 521-8100-8101-3890. These funds would be initially used to purchase the resin. Application to reimburse the City for the purchase of the resin as a part of the Water Supply Reclamation Project funded by Proposition 50 would reimburse the City for the $564,000. ENVIRONMENTAL IMPACT The initial study is complete and Notice of Exemption has been filed with the County Clerk.
