Sanitary sewer stoppages cause overflows which could potentially degrade the quality of local surface waters. They might also back-up into your establishment, or that of another, and cause extensive damage. If the interceptor is not properly maintained, grease can escape and cause a stoppage in your service or in the city main. A complete copy of this policy will be provided on request. The interceptor is usually a concrete tank buried outside the building with two manhole covers about five feet apart.
Some facilities rely on a small metal interceptor installed under a sink.
The interceptor traps grease by allowing it to float above the discharge pipe. If this layer of grease is not periodically removed, it will accumulate and flow out of the tank into your service and into the city main. If defects in the original installation or subsequent damage to the grease interceptor prevent it from functioning properly you will be required to make the necessary repairs. This is a steel tank with no plumbing connections, provided by a company that recycles grease and used cooking oil. By keeping most of your grease out of the drains, you will greatly reduce the stoppages in your plumbing and the loading on the grease interceptor.
