Metro Water District

Capital Improvements and Projects

Capital Improvement Overview - During its first two decades, the District actively constructed and upgraded critical infrastructure to ensure the reliability of its water system. The biggest challenge facing water utilities now and into the future is the need to replace aging infrastructure, which is projected to cost billions throughout the United States. Since the District has been proactive through two Capital Improvement Programs, the District has minimized significantly the risk of aging infrastructure and reduced overall costs in the future by paying now to make the various improvements.

1st Five-Year Capital Improvement Program - In 1997, a 79% voter approval gave the green light to the District's $23 million Capital Improvement Program (CIP) to address deficiencies identified in the 1994 Water System Management Plan. These deficiencies included insufficient storage and transmission main capacity to meet peak usage and fire flow demand. Implementation of the CIP was delayed until 1999 due to the litigation with the City of Tucson over the use of Central Arizona Project water. Since that time, Metro Water has remained on track with the various projects under the CIP, which has increased the overall reliability of the water system. A Bond Oversight Committee, now known as the Finance Oversight Committee, has watched over the CIP to ensure the monies are spent as the voters agreed.

Some key aspects of the 1st Five-Year CIP were:

• 43,800 feet of transmission mains installed throughout the system. Transmission mains are large water lines (12" to 30") that move large volumes of water through the system to then be distributed through smaller mains. Along with enhancing reliability, they also increase fire flow protection and allow for gravity flow.
• Seven key wells have been modified to allow for water to be introduced directly into the system.
• Mainline replacement projects replaced 73,700 feet of aged, undersized water lines to increase reliability, pressure, and allow for installation of hydrants.
• Telemetry system has been installed to allow well and storage sites to be monitored from a central location.
• Auxiliary Power was installed at key well sites to provide natural gas back up to electricity.
• 250,000 gallon storage facility was completed for Metro-Hub service area.
• Design of the Linda Vista Transmission main, the first leg of bringing Central Arizona Project water to be used either for replenishment, blending, or treatment.
• Design of the Northeast (Jim Tripp) Reservoir and Northeast Booster Station were completed.

2nd 10-Year Capital Improvement Program - In August 2004, the Board approved a second 10-year Capital Improvement Program to continue to upgrade Metro's service areas. While the 1st 5-year CIP had greatly improved Metro's overall system, it was recognized that further improvements are necessary to meet present and future water demands. A detail list of the projects identified under the 2004 10-year CIP is found under Appendix A.

In October 2004, the Board called for a bond election to finance the first phase of the 10-year CIP. In March 2005, 83 percent of those who voted approved the $28 million bond. Subsequently, the District obtained a low interest loan agreement from the Water Infrastructure Financing Authority of Arizona for the first phase of the 10-year Capital Improvement Program.

The projects identified in the $28 million bond program include the following:

• Northeast (Jim Tripp) Reservoir - construction of a 5-million gallon northeast reservoir to increase the District's overall storage capacity.
• Northeast Booster Station - construction of a 5 million per day pumping facility to life water to the Northeast Reservoir.
• Transmission Mains - Design and construction of approximately 37,000 feet of transmission mains. These large pipes, between 16" - 24" in diameter, will move more water throughout the District to and from storage facilities.
• Metro-Main and Metro Hub Main Line Replacement/Fire Hydrant Program - Approximately 13.5 miles of undersized and old service pipes in various neighborhoods were replaced.
• Metro-Hub New Well - An exploration well was recently completed at the proposed site. .
In 2008, the construction of the Northeast Reservoir and its respective booster station and transmission main were completed. The Northeast Reservoir was named the James M. Tripp Reservoir at a dedication ceremony held in March 2008.

Future Capital Improvements - The District has identified capital projects that will continue to improve the District's water system. Under its priority driven budget, the District will schedule annually those projects that can be funded. The main future capital project will be the construction of the CAP Recharge, Recovery and Delivery System. Other projects include another reservoir for Metro-Main, expanding the storage capacity for Metro-Hub service area, transmission mains, mainline replacement projects, replacement wells and well rehabilitations.

In October 2008, the Board decided not to pursue a bond election to obtain voter approval to finance a new CIP due to the financial uncertainties of the overall economy.

Project Descriptions

James M Tripp (Northeast) Reservoir
Construction of a 5 million gallon reservoir, located in the area of Magee Road and 1st Avenue, to serve the water storage needs for the northeast ‘B', ‘C' and ‘D' Zone service areas.

Northeast Reservoir Booster Facility
Construction of new booster facility, located at the intersection of Magee Road and Leonardo da Vinci Way, that pumps up to 5 million gallons per day from the ‘A' Zone system to the Northeast Reservoir located in the ‘E' Zone (‘D' Zone gravity feed).

Magee Road Transmission Main, Phase 3
Final leg of the transmission main system connecting to the Northeast Reservoir down Magee Road, from Northern Avenue to 1st Avenue.

Paseo Del Norte ‘C' Zone Transmission Main

Back to top

Village Avenue ‘C'/'D' Zone Transmission Main
Second of three transmission main project to connect the Magee Road Transmission Main to the existing distribution system in Village Avenue.

La Cañada Drive ‘C' Zone Transmission Main
Third of three transmission main projects to connect the Magee Road Transmission Main to the existing distribution system, and also serve as the first leg of a transmission main to connect the upper northwest and upper northeast service areas/zones.

Hub Storage Expansion
A 250,000 gallon storage expansion, and planning for one million gallons total, to provide build-out storage needs for the Metro-Hub service area.

Mainline Replacement Program
The mainline replacement/fire hydrant program exists to replace undersized and old distribution piping in various neighborhoods across the District, as well as provide additional fire protection for Metro Water customers. Several mainline replacement/fire hydrant projects were completed during the second capital improvement program within the Metro-Main and Metro-Hub service areas, though some needed to be postponed due to District obligations for waterline relocations on RTA roadway projects. In addition, several transmission main projects needed to be expedited so construction could occur in advance of the new roadways (that have also been expedited). Additional mainline replacement areas will be completed as funding becomes available.

Lomas De Oro Wash Improvements
Improvement of the Lomas de Oro Wash by the Town of Oro Valley from just south of Lucero Road, north through several private properties, including associated utility relocations.
