Water Usage Studies for Construction Activities




Project Details

In compliance with California Environmental Quality Act and National Environmental Policy Act, our client was required to complete water use studies to evaluate water consumption demand and establish feasible measures to mitigate impacts. ETIC was retained to conduct water use studies for large energy infrastructure projects to connect renewable generation projects to the transmission grid in Southern California and Nevada.

Our Approach

ETIC employed a numerical model that based the total consumption of water on a number of factors such as the area of disturbance, project duration, seasonal timing of the work, and use of access roads. The model provided an analysis to estimate the quantity of water consumption that would be required during various stages of construction.  The information was used to disclose environmental impacts to the arid regions of the proposed projects.  The water use studies were completed for the following projects:

Coolwater-Lugo Transmission Project

Construction is anticipated to begin in 2016 which will consist of approximately 65-75 miles of new high voltage transmission line, new Desert View Substation, and approximately 35 miles of new telecommunication cable to expand transmission capacity in the Kramer Junction and Lucerne Valley areas.

El Dorado-Ivanpah Transmission Project

Construction is underway on the new El Dorado Substation and 35 mile high voltage transmission line in San Bernardino County, California and Clark County, Nevada.

Jasper Substation Project

This project will connect new renewable generation projects in the San Bernardino County High Desert to the transmission grid.

Santa Barbara Reliability Project

Construction is anticipated to begin in late 2014 to improve the infrastructure of the south coast of Santa Barbara County and increase reliability to meet electrical demands during emergency conditions.

West of Devers

Construction is underway on the 48 mile high voltage transmission line between the existing Devers Substation (near Palm Springs), Vista Substation (in Grand Terrace), and San Bernardino Substation.
