The North Prosser Zone 2 Improvement project included construction of a new 1.2 million-gallon welded steel reservoir (120 feet tall, 42 feet in diameter), 4,000 GPM Booster Pump Station, and 5,000 linear feet of 12-inch and 16-inch transmission main. The extreme hard rock conditions made the project unique. Language on the plans and in the contract specifications were written specifically to protect the owner from change orders related to hard rock excavation. The project provides additional flow capacity and increased service pressures to meet current and future system demands and fire flow requirements of the North Prosser area.
HLA provided design, construction inspection, and startup coordination services for this important water improvement project.
