FROM: BRUNO RUMBELOW, CITY MANAGER
MEETING DATE: MARCH 17, 2026
SUBJECT: SERVICES FOR THE ELIMINATION OF THE BUILD UP OF FATS, OIL,
AND GREASE IN THE WASTEWATER COLLECTION SYSTEM
RECOMMENDATION: City Council to consider approval of an annual contract for biologically
based services for the elimination of the buildup of fats, oils, and grease
(FOG) in the wastewater collection system with IN -PIPE Technology (IPT)
for the Public Works Department.
FUNDING SOURCE: Funds are available in the Utility Enterprise Fund in an estimated amount
of $250,000.
BACKGROUND: Council originally approved a six-month trial on December 17, 2024, with
IPT in five locations within the City to improve the quality of our
wastewater collection system operations by microdosing bacteria to break
down fats, oils, and grease (FOG), This process reduces wear on the
wastewater system and helps to minimize blockages. The six-month trial
was completed and the City saw a benefit to treating FOG in this manner.
On August 19, 2025, Council approved additional funding for more
locations and an additional six months. This method of treatment has
continued to eliminate high levels of FOG and substantially reduced the
number of sewer line blockage and cleanings by City staff.
Based on the success of the two trial periods, we are proposing an annual
contract that will provide for the continued dosing of the microbe dosing
units (MDU) that reduces FOG and will include additional MDU's within
our collection system.
This purchase will be made in accordance with an existing interlocal
agreement with the Region VIII Education Service Center known as The
Interlocal Purchasing System (TIPS) in Texas as allowed by Texas Local
Government Code, Chapter 271 and Texas Government Code, Chapter
791.
Bids were taken by the cooperative and contracts were awarded to IN -
PIPE Technology. The Public Works and Purchasing staff reviewed the
contract for departmental specification compliance and pricing and
determined that the contract would provide the best product and pricing
for meeting the needs of the City.
Staff recommends approval.
