• Yes in most cases. Maricopa County Environmental Health Code (MCEHC) Chapter I, Section 2, Regulation 5 states: “For systems that treat, or which are designed to treat greater than 10,000 gallons/day, a standby power source shall be provided at all sewage treatment systems and/or pump stations where a temporary power failure may allow a discharge of raw or partially treated sewage. Standby power may be via a standby generator, separate feeders from separate substations, a loop feeder on separate transformers from a common substation, or a high-level alarm with portable generators.
