7157 Digester Gas Storage Replacement – City of San Jose, CA

Year Completed: October 2015
Capacity: 50,000 cu. Ft

This 50,000 cu. Ft. Low pressure gas holder was a replacement to a smaller unit at the facility. The treatment plant needed increased capacity with limited space, and so had to install this new gas holder in the same area originally occupied by the older unit.

This unit provides necessary capacity for increased demand from daily operation of the plant.

The city’s specification required that the gas holder be designed for an initial operating pressure of 6½ inches water column and to be able to accommodate an increased future operating pressure of 14 inches water column. The piston deck was designed to accommodate the future placement of additional ballast for the increased pressure.


Two 7.9 MG Equalization Tanks – Orange County Water District

Project scope included provided engineering, fabrication, erection and coating of two (2) 7.9 million gallon welded steel reservoirs. Foundation design for each tank required 449 concrete piles 60 to 65 feet deep, due to ground soil having extremely high liquefaction potential during a seismic event.

The project takes highly treated wastewater and purifies it through a three-step process that includes micro-filtration, reverse osmosis and ultraviolet light with hydrogen peroxide and then uses it to recharge the groundwater basin. It is the world’s largest advanced water purification facility of its kind prior to this expansion project, producing up to 70 million gallons of new water every day.

Each tank is 216 ft. diameter x 32 ft. shell height with a three bay roof structure. Construction of the two tanks utilized over 1,380 tons of steel. Both tanks were shop blasted and primed prior to field application of high performance 100% solids coating system on the full interior. It is estimated that the life-cycle of the tank coatings is 50 years.
