Executive Summary
Castle Rock Water (CRW) seeks Town Council approval of a Resolution (Attachment A) approving an agreement (Exhibit 1) with Aria Filtra Trojan Technologies Corp (Trojan), for the Plum Creek Water Purification Facility (PCWPF) Membrane Filter #3 Module Replacement Project, in the amount of $354,143, plus a 10% contingency of $35,415, for a total authorization amount of $389,558, as well as a sole source justification, (Attachment B).
Trojan will provide the membranes, and CRW staff will install the membranes. These modules will be ordered in February 2025 and installed after the 2025 demand season.
CRW has six water treatment plants within our overall service area. Aria membranes are included as part of the main treatment process at PCWPF which is the Town’s only plant that treats surface water for our community. The other five plants treat groundwater only. PCWPF was opened in 2013 and the Aria membranes have a life span of 10 to 15 years. This agreement is the second of four phases to replace the membranes over the course of four years. CRW has budgeted $450,000 annually through 2027 for this purpose.
Budget Impact
CRW has budgeted $450,000 per year for these replacements through 2027. The Rack #2 was replaced in 2023 for $365,899. The price this year is $354,143, but CRW is requesting a total authorization of $389,558 which includes a 10% contingency. Funding for this purchase will come from the 2025 Water Resources Plant Operations Repair & Maintenance Equipment fund, as shown below:
