Hazardous Waste Disposal Info

While we constantly monitor and clean our 200 miles of sewer system, there are 7 "hot spots" where our Field Services team finds the highest concentration of grease backing up in our system. If you live or own a business near these areas, please do your part to ensure FOG (Fat, Oil, and Grease) doesn't go down the drain! Restaurants use Grease Traps, and at home we can use an old tin can to pour off and cool hot grease before putting it in the garbage.

How Grease Traps Work

Every business that disposes of Fats, Oils or Grease (FOG) should have a grease interceptor to prevent these materials from entering and clogging sewer lines.

Grease Interceptors separate the grease and oils from the water that goes down your sink. Greasy wastewater entering the interceptor passes through a vented flow control fitting that regulates the flow of the wastewater. The wastewater then passes over a series of separator baffles, or regulating devices within the interceptor, that separates grease, fat and oil from the water. Grease then floats to the top of the interceptor and accumulates until it is removed by hand. The wastewater continues to flow through the interceptor, into a discharge pipe, and then to the District's sewer system.

Installing and Maintaining Your Grease Interceptor

Every interceptor should be cleaned as frequently as necessary to ensure consistent and proper operation.

To clean it, remove the cover of the interceptor and scoop out any grease and/or oil that has collected on top. Grease and oil can be recycled, and should be collected by a waste disposal company or grease recycling company.

It’s simple, the toilet is only meant to flush the three P’s – pee, poop, and paper. Unfortunately, over the years, people have turned the toilet into a trash can. From medications and sanitary products to deceased pet fish and cigarette butts, if it fits, people flush it. Flushing these types of items down the toilet causes home pipes to clog, waste water (up to 5 gallons of water every time you flush) and most importantly can have a huge impact on our  sewers, not to mention our ocean.

What 2 Flush?

Besides the three P’s the only other thing going down the drain should be what comes out of the faucet. The toilet is not the only drain that people are using to get rid of unwanted waste; people are also know to use the kitchen sink as a trash can. Letting trash flow and go down the kitchen sink (or any other drain in the house) may cause pipes to clog and can eventually lead to sewage spill that harm the environment.
