Since 1974, the District has contracted with the West County Wastewater District for a variety of services. WCWD provides routine maintenance, repairs and emergency response for the District's two pumping stations and the old plant facilities, and they recommend capital replacements and improvement projects to the Crockett Sanitary Department. WCWD also provides routine maintenance and emergency response for the Department's sewer system.

By providing necessary manpower, equipment and vehicles for collection system maintenance and emergency response, WCWD has relieved the Department of the need to employ its own workforce or purchase vehicles and equipment. This is considered to be a cost-effective arrangement for the Department.
