Who is the Coasta Water al Authority (“CWA”)? ( CWA )? ? ► Conservation and Reclamat tion District created by Special Act of the Texas e Legislature in 1967. ► Primarily serve industries an municipalities nd in Chambers, Liberty and Ha y arris Counties. ► Given powers, among other to transport rs, and deliver water inside and outside the 3- d 3 county area.

Who is the Coasta Water al Authority (“CWA”)? ( CWA )? ? ► Governed by 7-member Board of Direc ctors. ► 4 appointed by Mayor, City of Houston: ► Dionel E. Avilés, P. E., President ► Kurt F. Metyko, P. E., 1st Vice-President ► Tony L. Council, P. E., 2nd Vice Preside ent ► Rick Cloutier, P. E., Secretary-Treasure er ► 3 appointed by Governor, State of Texa as: ► Ray Stoesser, Liberty County ► A. R. “Rusty” Senac, Chambers County y ► Zebulun Nash, Harris County

What does CWA d do? ► Provide raw water to approx ximately 100 industrial customers. ► Provide raw water for munic water, cipal purposes purposes, to Houston, Deer Park, and Baytown. ► Operate and maintain Lake H O t d i t i L k Houston D t Dam, Reservoir and Pump Station and the West n, Canal.

What does CWA d do? ► Operate and maintain Trinity River Pump y Station, Main Canal, and the Lynchburg e Reservoir and Pump Station n. ► Operate and maintain assoc ciated pipelines ( (24” to 108”) and facilities. ) ► Own, operate and maintain 6.5 MGD water plant for industrial customer rs.

How did CWA getg involved in the Luce Bayou Project? y j ► In May 2005, COH requested that CWA proceed with the development of the Project. P j t ► CWA issued “Request for Qualifications”. Q lifi ti ” ► TCB INC was selected. ► “Notice to Proceed” issued April 19, 2006

Where is Luce Bayou? Lake Houston Approximately 25 miles northeast of Downtown Houston (H i and H t (Harris d Liberty Counties)

What is the Luce Baayou Interbasin Transfer Project? ► A conveyance project to traansfer existing COH water supply from the Trinity River Basin to the San Jacinto Riv Basin (Lake ver Houston). ► Estimated Project Cost: $ 30 million 00 (includes professional servic ces, construction, land acquisition, environmen mitigation, ntal permitting, and primary elec ctrical service).

What are the Proje ect Elements? ► Infrastructure sized to transf 450,000 acre fer 450 000 feet per year (400 MGD ave erage daily flow) from the Trinity River to Lak Houston. The ke Project consists of: ► New 500 MGD pump s p p station located on 90-acre parcel owned b CWA; by ► Approximately 3.6 mile of pipeline; es and ► Approximately 23 miles of new canal s canal.

Where Will the Wa be ater Treated? ► Water will be treated at the Northeast Water Plant (located on the west sside of Lake Houston), and the East Wat Purification ter Plant (located on the east si of Houston; ide Federal Road south of I-10).

The Luce Bayou PProject has Regional Impo ortance ► Over 3600 square miles ► 2 U. S. Senators ► 6 U. S. Representatives ► 10 State Senators ► 32 State Representatives ► Ultimately, Ultimately 9+ million people by 2060 (2007 State Water Plan)

Project Backgroun nd ► Project originally conceived in 1938 1938. ► Primary purpose was, and s is, to link still COH raw water supplies in t Trinity River the and San Jacinto River. ► Project P j t was designed and re d f d i d d eady for construction in the 1980’s. Project was postponed.

What is driving the development of the Project? ► Houston Galveston Subside ence District regulations have created a nneed for additional surface water to a allow conversion from groundwater to surface water. e ► City of Houston (Area 3) and North, Central d & West Harris County WA’s must convert from 100% groundwater to: ► 30% surface water by 2010 ► 70% surface water by 202 y 20 ► 80% surface water by 20330

What is driving the development of the Project? ► Conversion deadlines have also been developed for Fort Bend County: ► 30% surface water by 20113 ► 60% surface water by 20225 ► Lone Star Groundwater Con nservation District is implementing regulations for Montgomery County (2015) (2015).

What is driving the development of the Project? ► Population in Harris, Fort Be and Harris end Montgomery Counties is pro ojected to more than double from approxima ately 4 million (current) to 9+ million (2060) ).

Is the Luce Bayou P Project the solution? ►The Luce Bayou Pr roject is the optimal regional prooject identified in the ado opted 2007 State Water Plan to facilitate o the conversion from m groundwater to surf face water by providing additioonal surface water to the region. t t th i

How will the Project be Funded? ► Texas Water Development B Board (TWDB) currently has a loan program through its m “Water Infrastructure Fund” (WIF) which will defer project development ccosts. ► TWDB is anticipated to have a program to p e p g offer attractive construction funding. ► TWDB has the WIF money now. Ability to provide similar financing in t future is not the guaranteed.

How much water is needed from Lake Houston? Who nee the eds water? ►By January 1 2020 1, 0: ► City of Houston (NEWPP) 80.0 80 0 MGD ► City of Houston (West Can nal) 60.0 MGD ► NHCRWA 122.0 MGD ► WHCRWA 56.0 56 0 MGD ► NFBWA 34.0 MGD ► CHCRWA 5.4 MGD ► TOTAL DEMAND 357.4 MGD

How much water is needed from Lake Houston? Who nee the eds water? ►By January 1 2040 1, 0: ► City f H Cit of Houston (NEWPP) t 140.0 140 0 MGD ► City of Houston (West Can nal) 80.0 MGD ► NHCRWA 159.0 MGD ► WHCRWA 82.0 MGD ► NFBWA 56.0 MGD ► CHCRWA 6.3 6 3 MGD ► TOTAL DEMAND 523.3 MGD

Projected Demand v Supply vs for the City of Houst ton Total COH Water Rights

Projected Demand vs Supply in Lake Houston for the C of City Houston Lake Houston Supply (San Jacinto Rive er)

Projected Demand vs Supply in Lake Houston for the R Region Lake Houston Supply Lake Houston Supply

The Luce Bayou Proje solves ect the problem for the Re egion Lake Houston (San Jacinto) + Luce Bayou (Trinity) = 550 MGD + Lake Houston Supply Lake Houston Supply

Are We Developing “New Water? New w” ► No. No The Luce Bayou Projec transfers a ct portion of existing COH wate rights in the er Trinity River to Lake Houston (located on the San Jacinto River). Togethe there is er, sufficient surface water to m meet the projected demands of the City of Houston and the Regional Water Authorities beyond 2040.

Are There Other Op ptions? ► Water conservation measur will not res eliminate the need for Luce Bayou. ► Other surface water supplies (i.e., Brazos (i e River) do not currently have sufficient e availability. y ► Existing COH infrastructure (treatment plant capacities and transmission lines) cannot meet the needs of the Regioonal Water Authorities.

What s What’s the “Bottom Line”? Bottom Line ? ► Combined COH Water Righ in Trinity River hts and San Jacinto River are th only water he supply currently available. ► EWPP does not have the tre eatment capacity and the infrastructure does not exist to move the water to where it is need ded. ► Other options for conveying surface water from the Trinity River to Lak Houston are ke more expensive.

What s What’s the “Bottom Line”? Bottom Line ? ► The Luce Bayou Interbasin Transfer Project is the identified project to ad ddress the conversion needs in the targ areas. get ► The Luce Bayou Interbasin Transfer Project needs to be delivering additional surface g water to Lake Houston by Ju 2019. une ► The NEWPP needs to be ex xpanded to treat the additional surface water to be supplied r by the Luce Bayou Project.

Major Milestones f 2010 for ► Submit USACOE applicatio by March 31. on ► Complete“Preliminary Enggineering Report”. Obtain approval b Houston by PWE. ► Complete p acquisition of rights-of-way q g y and/or easements.
