The Water Authority’s Operations and Maintenance Department manages a fleet of approximately 90 vehicles, as well as heavy construction equipment. The fleet travels nearly 1 million miles per year, averaging more then 4,000 miles per workday. Recognizing the potential to reduce greenhouse gas emissions and operating costs, the Water Authority began implementing sustainable measures throughout the fleet several years ago.
The Operations and Maintenance Department evaluates all vehicles scheduled for replacement based on their use, driving patterns, past and projected maintenance costs, and potential for replacement with more fuel-efficient vehicles. Using this review process, the Water Authority has both eliminated vehicles and replaced vehicles with hybrids.
Additionally, GPS units have been installed in the Water Authority fleet. These units improve fleet efficiency through more effective vehicle dispatch and real-time analysis of vehicle engine performance (including vehicle speed). The Operations and Maintenance Department is also cutting emissions by retrofitting its on-road diesel vehicles with particulate matter filters, in compliance with California Air Resources Board requirements.
