Public Utilities Commissions in San Dimas, California

In California, Utilities are regulated by the Los Angeles County Public Services Commissions or Public Utilities Commission. Public Services Commissions are necessary when monopolies exist or in cases where competition is very limited, to ensure that San Dimas consumers receive safe, reliable, and reasonably priced services from competent and financially viable companies. San Dimas Utilities must receive approval for the rates they charge and they are also required to demonstrate to the San Dimas Public Services Commission that they have plans to maintain an infrastructure capable of supporting current and future demand for services.

Electric Utilities

San Dimas Electric Utilities are the most likely to function as a hybrid of monopoly and competitive services. Only one system for transmitting and delivering electricity to customers is feasible in a given service area such as Los Angeles County, CA. Therefore, transmission and distribution of electricity operates as a monopoly and customers do not have a choice when selecting their San Dimas electric power company. However, the electricity in the San Dimas electric grid may come from numerous suppliers.

Water Utilities

Water Utility Services in San Dimas provide potable tap water directly to residential, commercial, industrial, and institutional customers through a distribution system.

Sewer Utilities

San Dimas Sewer Service Companies receive wastewater from customers via sanitary sewers at a wastewater treatment plant. The Sewer Utility treats the wastewater to reduce pollutants before it is released into Los Angeles County waterways.

Natural Gas Utilities

San Dimas Natural Gas Companies are essentially local distribution companies that deliver natural gas, received from large capacity interstate or intrastate pipelines, to individual customers through small diameter distribution pipelines.
