Earl Thomas Reservoir

San Diego, CA

Completion Date
2005

Client
City of San Diego

Problem
The Earl Thomas Reservoir was constructed in 1957. However, in the late 1990’s, the reservoir fell under the ever-increasing scrutiny of the State of California Department of Safety of Dams due to its age and severe deterioration. The reservoir was considered a “house of cards”, highly susceptible to failure due to a seismic event. Therefore, the reservoir was removed from service in 1998. The reservoir roof was so unstable it was unsafe to even walk on the reservoir roof. (See Civil Engineering Magazine article “Earl Thomas Pre-Stressed Concreter Reservoir is World’s Largest”, June 2005).

Solution
BRADY staff conducted both internal and external inspections and prepared a structural and operational reliability analysis to determine the feasibility of rehabilitation, repair or replacement of the aging reservoir. BRADY was then retained to design the replacement of the Earl Thomas Reservoir, which included the redesign of Alvarado’s main treatment plant entrance, originally constructed in 1950, to improve security and appearance. BRADY also provided resident engineering services for the project and was responsible for day-to-day construction administration of civil site work, including the appurtenant piping, pumping, and flow control equipment required for operation of the new reservoir. The work also included a 60-inch diameter tunnel that hydraulically connected the Earl Thomas Reservoir to the twin 21.5 MG reservoirs completed in 1998.

Cost
$26,805,651

Delivery Method
BRADY acted as Project Manager, Designer, and Construction Administrator (advisor)

Outcomes
The Earl Thomas Reservoir project was an award winning project for the City of San Diego Water Department. All design work for this project was performed in accordance with the strictest project-specific quality control procedures, and in cooperation with client quality assurance requirements. The design was accomplished within budgetary and schedule parameters. Our stringent cost control procedures resulted in minimized construction change orders. At project completion, Richard Brady, P.E., BCEE was recognized by City of San Diego Mayor Jerry Sanders as the “100 Million Gallon Man”, due to Mr. Brady’s personal responsibility for planning, designing, and managing the construction of more than 100 million gallons of new and rehabilitated reservoir storage for the City of San Diego.

2-21MG Regulating Reservoirs, Alvarado

San Diego, CA

Completion Date
Design: 1992-1994
Construction: 1998

Client
City of San Diego

Problem
The City of San Diego was constrained by a site for a treatment plant designed in 1946, and had to expand due to a growing city and the more stringent drinking water quality regulations mandated by the Safe Drinking Water Act of 1986. The Alvarado Water Treatment Plant was required to ensure the adequate supply of clean drinking water to its 1.2 million residents via a water plant originally sized at 66 million gallons per day (mgd), that now required 200 mgd and new state-of-the-art clearwell reservoir storage, given the entire City of San Diego’s water supply to 500,000 residents was at risk in the event of a serious seismic event that would result in the collapse of the plant’s aging clearwells. The existing 20 MG rectangular reservoir, state of the art for its time in 1946, had already suffered the collapse of a roof panel that resulted in operational chaos. BRADY was tasked with designing new clearwell storage to meet the demands of a much larger city. In the end, BRADY successfully designed two new 21.5 MG reservoirs to fit in the existing 20 MG footprint – more than doubling the size without the additional need for a single yard of new real estate.

Solution
The design of two, 21.5 MG each, circular, prestressed concrete reservoirs, which serve as clearwells to the treatment plant and satisfy the daily water demands for a planned 2060 population of 1 million citizens. At the time of construction, the 21.5 MG size was the largest prestressed concrete reservoir in the state of California. And we built two, in the original 20 MG footprint.

Cost
$27,000,000

Delivery Method
Richard Brady, CEO of BRADY, was the Engineer of Record and served as Project Manager during the extensive design-bid-build process.

Outcomes
Public Awareness: The reservoirs are partially buried and a portion of the roof on one reservoir is dedicated to a Native Plant Demonstration Garden. The reservoirs were primarily designed to provide the City with storage facilities to meet their present and future needs; concurrently, this design enhanced the public’s awareness and understanding of local water issues.

Nationwide Project Award. The Alvarado Regulating Reservoirs project was awarded the American Society of Civil Engineers Outstanding Civil Engineering Project Award in 1998 in the water facilities category, and the American Public Works Associations 1999 National Project of the Year Award. The project also earned the recognition of the Associated General Contractors for Excellence in Underground Utility Construction. In addition, on May 4, 1999, by resolution of the City Council, City of San Diego, the Alvarado Reservoirs and Garden project was officially recognized as an important component of the City’s water distribution system.

5MG HP Reservoir Restoration Project

Vista Irrigation District (VID), CA

Completion Date
Design: 2016
Construction: 2017 - Ongoing

Client
Vista Irrigation District, CA (VID)

Problem
VID experienced a serious structural issue with a critical 5.0 MG, 55 year old prestressed concrete reservoir. In particular, the exterior prestressing wire and the roof integrity showed significant signs of distress.

Solution
At BRADY’s strong recommendation due to the possibility of failure in the event of a seismic event, the tank was immediately drained and removed from service to prevent a potential catastrophic safety hazard. The reservoir was constructed in 1961 in a remote area of Vista’s service area. In 2017, the reservoir is now surrounded by residential communities, extending right up to the site perimeter fencing. Concurrently, VID awarded BRADY a sole sourced contract whereby BRADY, using its r360® Design/Build Method (acting as general contractor and designer of record) developed a fast track restoration plan.

Cost
$3,490,000 (50% savings anticipated compared to new tank, not including the costly and environmentally challenging demolition of the existing 5 MG concrete reservoir)

Delivery Method
r360® Design/Build Method

Anticipated Outcomes
Application of new 7-wire galvanized strand prestressing and automated shotcrete. New wall footing and seismic cables. New low-profile aluminum roof installed. OSHA approved roof ventilation, exterior stairwell, and interior stairwell. A multitude of supporting design and repair upgrades resulting in a fully-code compliant and safe reservoir with many decades of enhanced service life.
