FROM: BRUNO RUMBELOW, CITY MANAGER
MEETING DATE: MARCH 17, 2026
SUBJECT: SERVICES FOR THE STUDY OF INFLOW AND INFILTRATION IN THE
WASTEWATER COLLECTION SYSTEM
RECOMMENDATION: City Council to consider approval of a contract for inflow and infiltration
monitoring 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 $40,000.
BACKGROUND: For Phase 1, IPT will provide flow sensors in manholes within the
southern portion of the City to be able to monitor and evaluate the inflow
and infiltration of storm water into the sanitary sewer system. This will help
to identify locations for sewer line and manhole repairs. Staff would like to
have these monitors in place prior to the start of heavy Spring rains.
The southern portion of the City flows to the Trinity River Authority sanitary
sewer interceptor, and the City pays for the treatment of these flows. The
study of this area will help eliminate unneeded flows to TRA and help with
our annual flow estimation and related expenses.
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.
