Project Overview

The original well had deteriorated beyond repair and the site was demolished.  A new well was drilled on site as a replacement well and the purpose of this project was to repurpose the well site for operation with the replacement well. Valentine designed improvements to equip a new 3,500 GPM 450 HP well pump with a variable frequency dr ive and sound enclosure. The well head discharge flow line consisted of a check valve, pump control valve, and well discharge flow meter (after waste), and other appurtenances for monitoring and control (gauges, switches, sample tap, etc). The well to waste flow line (after check valve) teed off from the well head discharge flow line and consisted of a well to waste control valve and flow meter. The well to waste flow line discharged to an on site 18-inch SRP irrigation line as required during SRP irrigation restrictions.  Electrical upgrades included design of a new service entrance system (4160VAC), a new Motor Control Center with a variable frequency drive motor starter and a low voltage transformer to power low voltage equipment, design of a new Remote Terminal Unit panel with radio communications, chlorination system electrical and controls, site light, security, and heat trace. The site civil design included a front wall, an entrance road, a site gate, and site grading and yard piping.
