Rehabilitation of Well No. 6

The City of Fountain Valley contracted Butier Engineering, Inc. to provide construction management and inspection services for the rehabilitation of Well No. 6.

• Replace the existing natural gas engine with an electric motor
• Furnish a 600 kW, diesel fueled emergency generator for standby power
• Construct a new 450 SF masonry building to house the new on-site sodium hypochlorite generation system
• Install a new 1,000-amp, 480-volt, 3-phase motor control center and switchboard
• Install a new 3-phase, 480/277 volt, 1,000 amp service to supply the well facility as well as the new on-site chlorine generation system
• Install intrusion detection switches on each entry door of the facility to alarm the City's SCADA system of unauthorized entry
• Replace existing 4-inch discharge to waste piping with new 8-inch piping
• Relocate existing 12-inch and 18-inch steel watermains
