With a water supply pumped from the Feather River, the Garden Highway Mutual Water Company provides irrigation deliveries through a 14-mile network of open channels to serve approximately 3,500 acres of rice and orchard. Several key diversion points did not contain infrastructure that facilitated accurate flow diversions and resulted in unwieldy flow changes and an inability to meet demands reliably without excess spillage.

The system modernization, measurement and real time monitoring and control project incorporated a strategic suite of improvements including a Supervisory Control and Data Acquisition (SCADA) system that enabled remote monitoring and control of the Company;s VFD controlled pump station, monitoring of seven groundwater well, sand level and flow at two primary spill sites. Data logging at all sites provides the client with tools for enhanced water management and accounting. Infrastructure improvements were constructed by replacing two water level control structures at key division sites with long crested weirs that maintain near constant upstream water levels regardless of flow and constructing two improved spill structures that improve control and the safety of canal operations.

Davids Engineering supported the client’s efforts in achieving their goals through grant writing, planning, design and construction management services. Additionally, we provided all SCADA design and implementation services.
