INTEROFFICE MEMORANDUM
Date: May 14, 2018
To: The Honorable Mayor and City Council
Through: Harvey Robinson, Interim City Manager
From: Dr. Hani Tohme, P.E., Director of Utilities
RE: PR 20259—Degreaser for Wastewater Treatment
Introduction:
The intent of this Agenda Item is to seek City Council's approval for the purchase of degreaser
and other biological aids of the control of grease, odor, and other unacceptable wastewater
conditions, in various lift stations throughout the city. The estimated annual total for all of
these chemicals is $60,000, and is budgeted from Account No. 410-1255-532.29-02, Treatment
Chemicals.
It is recommended that City Council approve P. R. No. 20259, authorizing the purchase of
various sole-source biological aids for the reduction of odor, fats, oils, grease, and other
undesirable conditions in lift stations throughout the City of Port Arthur, by the Water Utilities
Department.
Background:
Our Wastewater Conveyance crew will use these biological aids to keep sewer lines clear of
fats, oils, and grease. We have tested several chemicals in different lift station environments
and have found certain sole vendor-source products which work best in each unique lift station
environment. We currently have found four (4) different chemicals that help us reduce odors
and neutralize fats, oils, and grease in the collection system lift stations, depending on the
unique challenges at each site. All wastewater treatment chemicals are administered by trained
employees who are properly certified by the Texas Commission on Environmental Quality.
