Walnut Valley Unified School District upgraded their existing compressed natural gas fueling station that was originally installed in 1990. The original station consisted of two compressors, which were out of service for over five years. Seven of the dual time fueling posts restricted the school district’s ability to accommodate daily fueling of their fleet of 21 natural gas busses. The new station installed now consists of a dual skid-mounted compressor system complete with time-fill system controls, a communication panel, and eight additional dual-time fill posts. The school district has replaced three diesel school buses, which now brings the fleet to a total of 24 natural gas busses. Walnut Valley Unified School District plans to continue to replace their remaining fleet of seven diesel busses with natural gas busses.
