Regional Sewerage Service Contract With Inland Empire Utilities Agency (IEUA)
Inland Empire Utilities Agency (IEUA, formerly known as the Chino Basin Municipal Water District, CBMWD) is a municipal water district that distributes imported water from the Metropolitan Water District of Southern California and provides municipal / industrial wastewater collection and sewerage treatment services to more than 700,000 people within a 242-square-mile area in the western portion of San Bernardino County. The Agency provides service to the cities of Chino, Chino Hills, Fontana, Montclair, Ontario and Upland, as well as the Cucamonga Valley and Monte Vista Water Districts and the Water Facilities Authority.
The City of Upland and the six (6) other cities in the west end of San Bernardino County entered into a Regional Sewerage Service Contract in 1972 with CBMWD for the treatment and disposal of their sewage. The cities own and operate their own sewage collection systems that deliver their sewage flows into regional sewer trunk lines to the regional wastewater treatment at reclamation facilities.
Under this contract, the cities including Upland are obligated to adhere to certain quality standards for the wastewater conveyed and delivered to the regional systems. The cities pay IEUA for treatment and disposal of their sewage.
