Today’s Presentation

§ Brief History of TRWD

§ Regional Water Supply & Transmission Planning

§ Integrated Pipeline Project

§ Building the Big Idea!

2Tarrant Regional Water District - Integrated Pipeline Project

Tarrant Regional Water District

§ Created in 1924 as a political subdivision of State of Texas

§ Governed by an elected 5 member Board § 213 employees in facilities located in eight North

Central Texas counties• Guidance provided by four primary wholesale

customers: Arlington, Fort Worth, Mansfield and Trinity River Authority.

• Main functions are flood control ($24MM annual budget) and water supply ($79 MM annual budget)



TRWD Water Supply

§ Last year we provided 321,000 acre feet of raw water to our customers.

§ TRWD provides water to 70 cities in eleven counties. (Denton, Ellis, Freestone, Henderson, Jack, Johnson, Kaufman, Navarro, Parker, Tarrant, Wise)

§ Current service population is 1.8 million; projected to increase to 4.3 million by 2060.


TRWD Water Supply

• Permitted - 586,300 acre-feet.

• 2006 demands - 402,000 acre- feet.

• 2060 projected demand - 900,000 acre-feet.

• Region C Regional Water Supply Plan TRWD -430,000 acre-feet of new water supply prior to 2060.

IPL Features

§ A new right-of-way separated from the existing one to reduce risk

§ Different electrical feed high voltage substations for better reliability

§ Hydraulics and configuration to supply both Dallas and TWRD at peak times

§ Plans for growth in Ellis County and additional water supplies from east Texas in the future.




TRWD Planning

§ Apply the triple bottom line approach: People, Planet, Profit


X

Social

Environmental Economics

IPL Project – Opportunities for balance

§ Construction timing based on water demands§ Faster means more expensive – pipe production§ Richland Connection and KBR cutoff-Benbrook leg

will be the last TRWD segments

§ Exploring pipe material/backfill systems§ Five different geologic provinces§ native backfill potential§ Local select backfill – pea gravel§ Fly ash from Big Brown


IPL Design

§ TRWD standard details and specifications will be developed with input from all designers

§ Explore options – project size offers economy of scale for features

§ Reduce risk – geophysics for screening

§ Technology curve – cutting edge not bleeding edge – “pretensioned pipe?”

§ Reliability, redundancy and flexibility


PROGRAM MANAGEMENT


IPL Program Manager

§ TRWD made decision in mid-2009 to engage a Program Manager to assist in implementation of IPL Project

§ Team of RW Beck & AECOM selected in October 2009
