Title
Resolution Waiving Formal Written Bidding Requirement on the Basis of Sole Source for Services Provided by Pall Corporation [Entire Castle Rock Water Service Area]
Body
________________________________________________________________________________
Executive Summary
Castle Rock Water (CRW) seeks Town Council approval of a Resolution (Attachment A) approving a sole source justification (Exhibit 1) with Pall Corporation, for the Plum Creek Water Purification Facility (PCWPF) Pall Interface Upgrade Project for the amount of $106,866.
Notification and Outreach Efforts
This project is security sensitive and no public outreach is planned. Work will be performed at remote CRW sites and will be done out of the public eye
History of Past Town Council, Boards & Commissions, or Other Discussions
The engineering contract for PCWPF, which included the Pall Membrane system, with Burns and McDonnell was approved by Council on January 20, 2011 and constructed by Moltz Construction. The plant began operations in 2013 with four Pall Membrane filtration system racks. The expansion of the original Pall membrane system at PCWPF was approved by council on September 20, 2016, which increased capacity by 2 million gallons (MG).
Discussion
On a typical summer day, PCWPF receives 6 MG of surface water from Plum Creek. In the fifth step of water treatment at PCWPF, the water is pushed through Pall Aria Microfiltration membranes. Each membrane is less than 0.1 microns and helps remove particles such as bacteria, viruses and other microorganisms such as: E. coli, giardia, cryptosporidium and other microorganisms that may be present in surface water.
The Pall Aria Membrane System’s Numatic Pneumatic Solenoid Bank Interface (PSBI), currently in service on the Pall Membrane racks have been declared obsolete by Emerson, and repair parts are not available. Staff has been utilizing existing spares for replacements, but stock is low. The current PSBIs are unable to communicate with new Numatics G3 PSBIs. The entire system must be upgraded in order to work properly. Any failure of the PSBI equipment is considered detrimental, causing the Pall system to become inoperable, compromising filter production. Considering the lead time for the Numatics G3 PBSI equipment, of 10-14 weeks, it is critical to get the equipment ordered immediately.
