0n July 28, 2049, ~M&C C-23696 City Council au#horized an Engineering Agreement in the amount of
$954,283.00 with Malcolm Pirnie, Inc., for the inspection of a sanitary sewer interceptor and odor and
corrosion control services for the interceptor and at Village Creek Was#ewater Treatmen# Plant
~VCWWTP~. This proposed con#ract amendment will provide additional inspection services of a 96 inch
interceptor from Gateway Park #o the VCWWTP, the 96 and l2 inch interceptors in the VCWWTP levee
and inspection services for up to 400,000 linear feet of 8 to 12 inch sanitary sewer mains a# various
locations throughou# the City.
Approximately 80 percent of the sanitary sewer flow into VCWWTP is transported through two 96 inch
concrete interceptors running roughly along the West Fork of the Trinity River from the old Riverside
Wastewater Treatment Plant (Gateway Park). These lines cross several major arterials and cross under
the East Loop of Interstate Highway 820. One interceptor was installed in 1963 and the other in 1977.
Both of these lines must be in service at all times to meet the sanitary sewer demands of the customers in
the service area.
The original contract provided a full scale inspec#ion of M280, the older Wes# Fork interceptor. This
proposed contract amendmen# provides a full scale inspection of M338, the 1971 West Fork in#erceptor, to
se# a benchmark of the pipeline condition and to identify locations of potential critical failures. The
inspection will be performed with the line in service and includes sonar, laser and television data. The
laser scans will reveal the remaining pipe wall thickness, the sonar scans will map debris accumulated in

the pipe and the television data provides visual information on the condition of the system.
The proposed amendment also includes services to investigate the condition of two interceptors, one 96
inch and one l2 inch located in the VCWWTP levee. Two sections of the 96 inch pipeline failed in 2001
and required emergency repair. An attempt to inspect these lines previously failed due to debris in the line
and failure of the pipe.
Proposed services also include robotic equipment use for two eight week periods to remotely inspect 8 to
12 inch sanitary sewer mains at various locations throughout the City. About half of the sanitary sewer
collection system is comprised of mains less than 12 inch. Equipment use and data management services
for up to 400,000 linear feet of pipe are included.
The equipment used to perform the sanitary sewer inspection work in this Contract Amendment is highly
specialized and proprietary.
In addition to contract costs $20,000.00 is included for staff support.
This project is located in COUNCIL DISTRICTS 4 and 5.
A waiver of the goal for M/WBE subcontracting requirements was requested by the Water Department and
approved by the M/WBE Office because negligible M/WBE subcontracting opportunities exist.
FISCAL INF~RMATI~N 1 CERTIFICATION:
