    About Us

    The Costa Mesa Sanitary District (CMSD) is an independent special district formed in 1944 under the Sanitary District Act of 1923. Our boundaries encompass the city of Costa Mesa and small portions of Newport Beach and unincorporated Orange County, serving a population of approximately 118,000.

    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.
