About CMSD

Our boundaries encompass the city of Costa Mesa and small portions of Newport Beach and unincorporated Orange County, serving a population of approximately 116,700.

As a sanitary district, we are responsible for residential solid waste (trash) collection and its transmittal to recycling facilities for sorting, recycling and disposal. Additionally, we maintain a wastewater (sewer) collection system that collects and transmits wastewater to Orange County Sanitation District facilities for treatment and disposal. These core responsibilities are accomplished through a combination of public and private services, which include an in-house administrative and wastewater maintenance staff and a privately contracted trash hauler, attorney, treasurer and engineer.
