Regional Treatment Plant Cogeneration & Switchgear Upgrades

Butier Engineering, Inc. provided comprehensive construction management and field quality assurance services throughout pre-construction and project closeout phases. In addition, the original location for the electrical building was changed due to underground utility conflicts. Several modifications were necessary to accommodate the routing and installation of new electrical service from SCE. Butier’s electrical engineer examined the electrical installation and assisted SOCWA staff with submitting a letter to SCE requesting energization.
