The City does not endorse the use of bacteria or enzymes. Bacteria and enzymes are ineffective in a grease trap or interceptor where retention time is inadequate, where there are surges in flow volume, where there are changes in grease volumes, or changes in the temperature of the wastewater. Using these can make grease a problem downstream. Excessive use of drain cleaners can damage your sewer line causing major problems and costly repairs. Remember know your sewer system.
Inspect system components periodically.
Clean drain lines regularly. Properly dispose of grease and oil. Clean the trap frequently to reduce grease volume and cleaning time. Don't Obstruct grease trap. Use hot water to flush sewer lines.
