The Problem

Bergelectric Corporation, a nationally recognized electrical contractor, recently finished on-site construction of the “mission critical” electric power emergency/backup generation system for the new $700-million California Health Care Facility in Stockton, CA.

Bergelectric, responsible for feeding power to the 144-acre site, supplied the core support facilities that serve as the backbone of operations. One of the most significant aspects of Berg’s role on CHCF-Stockton was the integration of normal and emergency power.

Oldcastle Precast supplied the specialized fuel storage system that feeds the 2 MegaWatt Caterpillar generators for emergency power.

The Design

Oldcastle Precast/ConVault sales team collaborated with customer/partner, Rich Hamilton, Special Projects Manager for Donlee Pump Co. and Berg’s Dan Winkels, project engineer for this project. The team designed and constructed a custom, site specific fuel supply system to feed six - 2 MegaWatt Caterpillar generators.

ConVault Protected Fuel Storage Tank

The Solution

The fuel supply system includes one 2,000-gallon ConVaultday-tank which was supplied by four large 10,000-gallon ConVault auxiliary storage tanks.

The 5-tank array is fully monitored and auto-managed to provide re-circulation of fuel product and refueling of the day-tank “on demand”.

Rounding out the comprehensive system design is a unique fuel filtration system, using a Velcon 60 GPM aircraft style filter module and differential pressure gauging/compensating systems, to ensure fuel quality and purity.
