INTEROFFICE MEMORANDUM
Date: August 21, 2019
To: The Honorable Mayor and City Council
Through: Ron Burton, Interim City Manager
From: Donald G. Stanton, Interim Director of Utilities
RE: PR 21028—Polymers for Water and Wastewater Treatment
Introduction:
The intent of this Agenda Item is to seek City Council's approval for the purchase of polymers
for water purification and wastewater treatment. Our water purification and wastewater
treatment processes use polymer coagulants to remove solids from water. Each process uses a
unique blend of chemicals for maximum effectiveness. These polymer blends are sole-source
and proprietary in their make-up. This Resolution authorizes the purchase of each of these
products as each is needed so that our treatment personnel may make use of the most cost-
effective treatment system at any given time. We anticipate that coagulant polymer and
polymer aid purchases this year for Water Purification Division will total an estimated
$1,510,000.00. They will be used on an as-needed basis and charged to account no. 410-1252-
532.29-02, Water Treatment Chemicals. We anticipate that polymer purchases for Wastewater
Treatment Division will total approximately $135,000.00, also used on an as-needed basis and
charged to Account No. 410-1256-532.29-02, Wastewater Treatment Chemicals.
Background:
Our water purification and wastewater treatment processes use polymer coagulants to remove
solids from water. Each process uses a unique blend of chemicals for maximum effectiveness.
These polymer blends are sole-source and proprietary in their make-up. This Resolution
authorizes the purchase of each of these products as each is needed so that our treatment
personnel may make use of the most cost-effective treatment system at any given time. All
