Installation costs (new construction) for a gravity grease interceptor averages $3,000 to $7,500, depending on the type, size, and location required for installation. Generally, hydromechanical units (installed under sinks) cost about $300 to 500, but require more maintenance and frequent (daily or weekly) cleaning. Some hydromechanical unit maintenance and cleaning activities can be performed by trained kitchen staff. Collected grease and debris can be lawfully disposed of in "brown-grease" receptacles available through licensed grease haulers. For large interceptors, most food preparation managers find it necessary and cost-effective to contract with a professional service provider to clean and dispose of collected grease and debris on a regular/scheduled basis.
