SUBJECT
Consider adoption of an ordinance of the City of Denton, a Texas home-rule municipal corporation,
authorizing the City Manager to execute a contract with Pure Technologies U.S. Inc., to provide a condition
assessment of the City’s 27-inch diameter Lake Lewisville raw water line; providing for the expenditure of
funds therefor; and providing an effective date (RFP 7347 – awarded to Pure Technologies U.S., Inc., in
the not-to-exceed amount of $612,000). The Public Utilities Board recommends approval (4 - 0).
INFORMATION/BACKGROUND
The Lake Lewisville Water Treatment Plant (LLWTP), provides approximately 60% of the City’s treated
water to the water distribution system. The LLWTP is supplied with untreated (raw) water from a pump
station located on the Hickory Creek arm of Lake Lewisville. The raw water transmionssion pipeline system
was built in phases with a 27-inch diameter Bar-Wrapped Concrete Cylindar Pipe (BWP) pipeline
constructed within a 30-feet wide pipeline and electric power line eaement in 1956-57 and a 30-inch
diameter BWP pipeline constructed within a Union Pacific Rail Road righ of way in 1975. The raw water
supply lines runs approximately 8.5 miles from Lake Lewisville to the Lake Lewisville Water Treatment
Plant. After leaving the pump station, the pipes run under I-35E, and then north along the Denton County
Transportation Authority’s (DCTA) railway corridor.
The 27-inch and 30-inch pipelines have experienced some recent failures and the quality of the pipe bedding
material and installation are of continued concern. Due to the failure history and the competing usage of the
Rail/Trail corridor, staff planned to perform pipeline conditions assessments on both raw water lines. The
30-inch waterline was evaluated and reparis made over the past several years.
Staff prepared a Request for Proposals to select a vendor to provide an in-pipe electromagnetic and closed
circuit television assessment of the 27-inch pipeline. Pure Technologies U.S. Inc. provided the highest
ranked proposal to inspect the entire pipeline, identify failures and areas of concern, and produce a report
outlining the condition of the pipe. This report will be used by City staff to identify areas in need of repair
or replacement.
This project is the first phase of the rehabilitation, repair, or replacement of the 27-inch raw water
transmission line for the Lake Lewisville Water Treatment Plant.
Requests for Proposals was sent to 334 prospective suppliers of this item. In addition, specifications were
placed on the Materials Management website for prospective suppliers to download and advertised in the
local newspaper. Two (2) proposals were received and evaluated based upon published criteria including

delivery, compliance with specifications, probable performance, and price. Based upon this evaluation,
