City Council Memorandum Public Works & Utilities Memo No.
UA21-053
Date:
June 24, 2021
To:
Mayor and Council
Thru:
Joshua H. Wright, Acting City Manager
Debra Stapleton, Assistant City Manager
John Knudson, Public Works and Utilities Director
From:
John Pinkston, Wastewater Facilities Manager
Subject:
Sole Source Purchase of Wastewater Membrane Modules
Proposed Motion:
Move City Council approve the sole source purchase of wastewater membrane modules, from SUEZ Water Technologies & Solutions, Inc., in an amount not to exceed $300,000.
Background/Discussion:
The Ocotillo Water Reclamation Facility (OWRF), located at 3333 S. Old Price Road, treats 18 million gallons of the City’s wastewater every day. This plant uses two different methods of treatment to produce A+ quality effluent for delivery to the City’s reclaimed water system. To meet the increasing demand for wastewater treatment and the growing demand for reclaimed water, OWRF was expanded in 2015 to the current 18 million gallons a day treatment capacity. This plant expansion was designed and built to utilize microfiltration technology. Microfiltration uses an advanced membrane technology that filters water through very fine laser-cut membranes which remove impurities down to the microscopic level. Staff has determined that there is room for additional membrane filters that would improve system capacity and reliability. This purchase will include additional filters to increase the current capacity and reliability of the microfiltration system as well as installation and commissioning assistance of the additional filters.
Evaluation:
The Public Works & Utilities Department utilizes SUEZ wastewater membrane modules at the Ocotillo Water Reclamation Facility. SUEZ Water Technologies & Solutions, Inc., is the sole provider of these membrane modules. Staff recommends the purchase of SUEZ membranes as a sole source.
