An oil and grease interceptor is a waste treatment tank that uses only gravity and time to filter wastewater from kitchen sinks and drains. It is a large concrete tank with two chambers, installed underground, with manhole covers for access, buried outdoors in the parking lot or landscaping area. Oil and grease floats, the solids sink, and the clarified wastewater in the middle passes through to the public sewer system.
Oil and grease interceptors capture solids, oils and grease, which slowly accumulate in the two tank chambers instead of discharging to the sewer. Without interceptor maintenance, accumulations would eventually cause a block and your kitchen drains would stop working.
Oil and grease interceptors require periodic maintenance by a pumping and disposal company. This can be scheduled on a calendar basis, or as needed. Oil and Grease Interceptors must be pumped before they exceed 25% solids and grease.
