Do you have an exterior tank that is not connected to the sewer, and wondering if you still need a grease trap connected to your sink(s)?
Yes, you will still need to have a trap connected to your drains. If you have good maintenance records of you exterior trap, you may be able to size your interior trap a bit smaller to save money. Also, you can save money by performing management practices like scraping and wiping so that all grease does not end up in your external tank. How can I save money on pumping costs? Keep grease out of your sewers by wiping, scraping and disposing of grease. Reducing the load to your grease trap will reduce the frequency and cost of pump-out. I don’t have a grease trap. How long do I have to install one and where do I start? Your grease trap will need to be designed to treat the expected volume of grease from your facility. Your first step should be to hire an engineer, who can give you the best information regarding sizing and location. You should plan to have one installed within six months, or by September 2007.
