Trinity Regional Water District (UTRWD).
Julie Smith with the Town of Flower Mound and Mr. Robert Smith with Kellogg Brown &
Root, Inc., addressed the Council with a presentation concerning an analysis of Alternatives
for future water supply relating to the proposed Lake Ralph Hall.
Ms. Julie Smith, Director of Services for the Town of Flower Mound, addressed the Council
with concerns that the cost analysis of UTRWD for future raw water supply is not the most
cost effective plan in the development of Lake Ralph Hall.
Robert Smith, engineer for Kellogg Brown & Root, Inc., gave a lengthy presentation
concerning the alternative in regards to their analysis for future water supply and needs.
In Summary:
• Dallas has committed to meet UTRWD'3 water supply needs for its existing customers
through 2060.
• On a regional basis the unit cost of water will increase as demand goes up, because new
sources will be more expensive to develop and operate.
• Larger projects tend to be more cost effective because of the economy of scale.
• Lake Ralph Hall was determined not to be cost effective as a future water supply for
UTRWD compared to other sources.
• The building of Lake Ralph Hall will be at least 2.5 times more expensive than
purchasing water from Dallas.
• The construction of Lake Ralph Hall will not Reduce UTRWD dependency on Dallas,
as more than 75% of its future water supply still comes from Dallas.
• Because of upstream channelization, high sedimentation rates could cause Lake Ralph
Hall yield to decline faster than normal reservoirs.
• Lake Ralph Hall is not necessary for UTRWD to be able to meet its customers' future
water demands in any current planning horizon.
The construction of Lake Ralph Hall will require cities and businesses of Denton to pay higher
cost then necessary for future water supply needs.
Randy Stalnaker5 Upper Trinity Regional Water Dist., gave a report on the UTRWD Long
Range water supply strategies.
UTRWD Needs Additional Water Sources, discussion summarized as follows:
• The service area is growing rapidly
• Dallas contract expires in 2022
• Reasonable cost, which will be feasible and realistic.
• Mitigation centered within project area.
• Existing environmental issues discussed.
• lowest cost source of new water.
• Can be built in a timely manner
• They are dedicated to serving all members.
• It will be governed by the members.
• UTRWD to use Multiple Long Range Water Supply Srategies
• Use maximum water from Dallas -per contract
• Use and Reuse maximum water from Chapman Lake
• Increase conservation
• Develop Lake Ralph Hall, and reuse water from this source
• Jointly pursue other Regional Strategies
