Water and Power Subcommittee Hearing
SD-366 Energy Committee Hearing Room 02:30 PM
Mr. Chris Lippe
Director, City of Austin Water Utility
Chairman Murkowski, Ranking Member Johnson and Members of the Subcommittee, thank you for the opportunity to appear before you today to testify in favor of HR 2341. I would also like to thank Representative Doggett, for introducing this bill and our entire Congressional delegation for all of their hard work on
My name is Chris Lippe, P.E., and I am the Director of the City of
In my testimony, I will provide information on HR 2341, Austin and its water needs, our efforts to meet those needs, and the role that we envision for the Bureau of Reclamation’s Title 16 Program in helping to meet those needs.
HR 2341
HR 2341 amends the Reclamation Wastewater and Groundwater Study and Facilities Act to authorize the Secretary of the Interior to participate in the design, planning, and construction of a project to reclaim and reuse wastewater within the service area of the Austin Water Utility.
About the City of
The City faces two major challenges in meeting the needs of its customers. First, there is a projected water need. The City’s current water rights and water contracts are expected to meet demand until approximately 2042. By 2050, however there will be an anticipated water shortage of 42,096 af/yr. That is enough water to serve 63,000 residences, or an equivalent population of 221,000 in contrast to our served population of 770,000. Water conservation measures are expected to provide half of the shortfall, leaving the other half to be provided by some alternative measure, such as reclaimed water.
The second need is financial in nature and relates to funding constraints under our capital improvement plan. The City, through its current capital improvement plan has identified almost $1 billion in infrastructure needs in the next five years. Much of that is devoted to water treatment plant expansion, wastewater treatment plant expansion, and rehabilitation of the wastewater collection system to meet the needs of a growing community. This of course does include some funding for a growing reclaimed water program.
The expansion of our water reclamation system will provide a number of benefits. It alleviates the potential for water shortages. It defers millions of dollars in annual payments under our raw water contract. Finally, it can help defer the need for the construction of additional water treatment plants.
The Reclaimed Water Program
Based on the quality of the reclaimed water, the major uses for it in
Reclamation and Reuse Project -- Central System
The central reclaimed system provides water from the Walnut Creek Wastewater Treatment Plant (WWTP). In 2005, the most recent full year of data, customers used almost 60 million gallons of reclaimed water. Piping in the central reclaimed system consists of 4 miles of transmission main. Pumping equipment consists of two low-service pumps, a one million gallon ground storage tank, and three high-service pumps at the Walnut Creek WWTP. The central reclaimed system has one project in the preliminary engineering design stage – a two million gallon elevated storage tank and an additional mile of transmission main.
Reclamation and Reuse Project -- South System
The south reclaimed system consists of a pump station, a booster pump station, a 0.5 million gallon elevated storage tank, and 15 miles of piping carrying treated wastewater effluent from the South Austin Regional WWTP. Customers include the award winning Hornsby Bend Biosolids Management Facility, the
Reclamation and Reuse Project -- Satellite System Details
The Austin Water Utility operates three satellite systems that are located on the fringes of its service area. With a satellite system, wastewater flows are geographically matched with potential customers and a water reclamation plant is built in the immediate vicinity. In 2005, the Davenport WWTP provided 81 million gallons of reclaimed water for golf course irrigation. The Onion Creek WWTP produced 58 million gallons of reclaimed water for golf course irrigation. Finally, the Balcones and Pickfair WWTPs provided 79 million gallons of reclaimed water, again for golf course irrigation.
Reclamation and Reuse Project – System Growth
As mentioned above, the City has approximately 19 miles of existing transmission main in the southern and central part of its service area as well as pump stations and storage tanks at the
With Federal assistance, the reclaimed water system can grow dramatically. The miles of transmission mains will expand to from 19 to 137, an increase of more than 700%. Storage tanks in the distribution system will grow from zero to seven with a combined storage capacity of 14.3 million gallons. Pump stations in the distribution system will increase from one to a total of five. The number of pressure zones will increase from two to five. Plant storage tanks will increase from two to three and their capacity will increase from 2.5 million gallons to 3.5 million gallons. The magnitude of system growth requires that improvements be built over a period of years. Construction is projected to ramp up in 2008 and concludes in 2035, with the system reaching full capacity in 2039.

Financial Constraints Facing
A significant constraint to implementing our Reclaimed Water Program is funding. The Environmental Protection Agency, the American Water Works Association and the Association of Metropolitan Sewerage Agencies have all documented the enormous infrastructure needs of water and wastewater utilities.
We acknowledge that under the Title 16 Program, federal funding is capped and that the City will have to cover the bulk of the costs under Title 16. We estimate the City’s portion as being 87% of the total cost and the City is prepared and committed to fully fund its portion. However given the importance of addressing water needs and water quality, federal assistance with this project is appropriate and welcome.

Bureau of Reclamation's Title 16 Program
The Bureau of Reclamation operates a well-respected water reclamation program, referred to as the Title 16 Program. It is designed to improve efficiency in the use of water resources in the western states. Section 1602 of Public Law 102-575 establishes broad goals for Reclamation in administering the Title 16 Program. These goals include:
• Identifying opportunities for reclamation and reuse of municipal wastewater,
• Investigating those opportunities and,
• Providing a cost-share opportunity for an appraisal and feasibility study and for the design and construction of permanent facilities to reclaim and reuse municipal wastewater.

Conclusion
In summary, the expansion of our water reclamation system provides a number of benefits. It alleviates the potential for water shortages in the near- and long-term. It delays and reduces annual payments under our raw water contract by millions of dollars. Finally, it reduces infrastructure costs by reducing and water plant sizing.
