Restaurants and their grease interceptors

Kitchens that cook for the public send fats, oils and grease down their drains. Most sewer owners require a grease interceptor between the kitchen and the public sewer: a buried tank that lets grease rise and solids settle so that only cleaner water flows on. An interceptor works only if it is emptied regularly and kept in good repair.

Work on an interceptor usually falls into one of these:

Pumping and cleaning

An vacuum truck removes the grease, solids and water so the tank can be inspected, as the sewer owner's rules for the material allow.

Repair

Baffles, tees, lids and risers corrode or break; they are replaced so the tank works as designed.

Replacement or new installation

A tank that is too small, failing or missing is replaced or installed to the size the sewer owner requires, with the inlet and outlet lines rebuilt.

Records

The sewer owner often asks for proof of cleaning and inspection, so dates and findings are recorded.

The same steps apply to sand and oil separators at garages and car washes.

We also handle water service, lateral, storm and conduit work for homeowners and other businesses in Charleston.
