Fueling System Construction

WPI has been involved with fueling system construction services since the company’s inception in 1968.  In 1970, when the US Government mandated that leaded gasoline be phased out of use, WPI was selected by Shell Oil Company and ARCO Petroleum Products as a sole-source vendor to install USTs for unleaded gasoline throughout southern California.  This work required the installation of an additional underground storage tank (UST) at virtually every service station.  This unprecedented undertaking catapulted WPI to the position of UST and fueling system installation service leader. WPI is proud to state that not a single one of the more than 3,000-UST installations completed during this effort have failed due to improper installation or contractor error.


During the intervening years, we have continued to grow and refine our fueling system construction capabilities.  As a result, we haves been continuously selected to develop and implement innovative installation techniques and fueling system technologies. For example, regulatory agencies periodically require that fueling systems be upgraded to ensure proper operation and to maintain compliance with evolving regulatory requirements pertaining to USTs.  Today, most fueling facilities in California have an upgraded secondary containment or Stage I vapor control product designed by WPI Vice President and Principal, Thompson Wyper.
