Re: Water System Master Plan
Upper Trinity Regional Water District
Dear Mr. Griffin:
We have initiated contact with the Upper Trinity Regional Water District (UTRWD) regarding the
opportunity to be involved with it's water supply network in the Denton County / North Dallas County area.
We understand that the City of Coppell was given an opportunity to become a member city in or around
1990, however at that time the City made a decision to decline. Mr. Tom Tayler of the UTRWD was kind
enough to provide information regarding their system and the options available to the City of Coppell with
regards to obtaining Upper Trinity water.
There were two options mentioned by Mr. Tayler in our conversation:
Approach the UTRWD to become a current member. If this status is granted, the district would
construc! the infras~acture necessaw to deliver water to the City of Coppe!l Unfortunately, the
UTRWD has closed membership and it would take an act of the Board of Directors to allow Coppell
to join. It is likely that there would also be a significant price tag attached to becoming a member.
Water would then be purchased on a negotiated fee schedule (of which we had no conversation).
Approach the UTRWD to become a customer city. If this status is granted, the City of Coppell
would be responsible for construction of the infrastructure to bring water from the closest delivery
point to the City's existing distribution lines. Water would be purchased on a negotiated fee
schedule (of which we had no conversation). The closest delivery point is the Upper Trinity
Regional Water District Water Treatment Facility located adjacent to the comer of Kealy North and
Sewage Treatment Road in Lewisville. The shortest delivery line would likely travel south on
Kealy, along Hwy. 121 (Bus.), and continue down Denton Tap Rd. to a connection point
approximately 2000 feet north of Hwy. 121/Spur 553. The total length of this line is approximately
4.7 miles.

According to the current Water System Master Plan, the City of Coppell will require an additional 9 MGD
capacity at build-out. The opportunity to provide for that capacity increase through an alternate water
source in the UTRWD could be attractive. At this point further study is recommended to investigate the
feasibility of the Upper Trinity Regional Water District as this provider. The infrastructure costs must be
weighed against the volume and demand charges for each scenario. At the direction of the City, these
options can be studied and a report prepared.
We are available to discuss the information provided in this letter at your convenience.
