Grease Issues

Here are some tips to help you learn how to avoid grease problems.

Is Grease a problem?

In the sewage collection and treatment business, the answer is an emphatic YES! Grease is singled out for special attention because it collects in sewer lines and can completely plug a pipe. Grease in warm water or liquid may not appear harmful. But as the liquid cools, the Grease hardens and collects on sewer mains and pumps. This may cause sewer backups and/ or problems at the city's wastewater treatment plant.

Residential

To help eliminate this problem, all grease or oils from cooking or automotive repairs should be put into containers for proper disposal. 

It makes no sense to spend precious dollars collected from rates to clean Grease out of sewer pipes.  These expenses can be avoided simply by each one of us properly disposing of Grease rather than washing it down the drain.

Commercial Grease Issues

Large amounts of oil and grease in the wastewater cause trouble in the collection system pipes and the wastewater treatment plant. It decreases pipe capacity and, therefore requires that piping systems be cleaned more often and/ or some piping to be replaced sooner than otherwise expected.

Problems caused by wastes from restaurants, food processing facilities, and other grease producing establishments have served as the basis for ordinance and regulations governing the discharge of grease materials to the sanitary sewer system. This type of waste has forced the requirement of the installation of preliminary treatment facilities, commonly known as grease traps or interceptors.

Do I need a Grease Trap?

If you use oil or grease in your establishment and they are washed into the sanitary sewer system, then you should have a grease trap or interceptor.

Is the Grease Trap I have adequate?

The size is largely determined by your maintenance schedule. If you have to clean it more often than you think you should, chances are the size needs to be increased. Typically, a drive-in restaurant will require between a 70lb. to a 100lb. interceptor depending on the food being prepared.

What if I don't install a Grease Trap?

If you are a restaurant owner and use oil or grease in you food preperation, you will eventually have a maintenance problem with a plugged building sewer line. This blockage can create a sewer back-up situation and ultimately a health problem in your restaurant. Someone will have to pay to remove the blockage. If the problem is in your building sewer line, then you will have direct responsibility for paying for the maintenance. If the blockage or restriction is in the public sewer main and it can be proven that you are the cause of the blockage, then you may also have to pay for the public sewer to be maintained.
