12th Annual Grease Collection and Recycling Event a Huge Success!

Grease Pour

The 12th Annual Grease Collection and Recycling Event took place on January 7, 2017. This event gave you an opportunity to start the New Year off right by dropping off your used cooking oil and grease from all your holiday cooking and baking.

We collected 715 gallons of used cooking oil and grease; that’s 5,363 pounds of FOGs (fats, oils, and grease) that did not flow down Pima County drains! That’s a record!

The Pima County Regional Wastewater Reclamation Department and partners Grecycle, Edge Group, Pima Association of Governments, the Town of Sahuarita and newest partner, CH2MHill, want to thank the community for coming out and supporting this effort! Save your used cooking oils and grease throughout 2017, and bring it to us again during our January 2018 event!

The collected grease will be recycled into biodiesel, a cleaner burning fuel than regular diesel.

If you were unable to visit one of our grease collection sites on January 7, 2017, you can always recycle your grease at the year-round located listed below:

What Can I Put Down My Drains?

Are there other substances I should not put in my drains or toilets? How should I dispose of hazardous waste?

Don't put automotive fluids, pesticides, solvents, and other similar substances down the drain. Select less toxic alternatives whenever possible and dispose of any household hazardous materials through the County/City Household Hazardous Waste Collection Program. Wastes are collected at the Household Hazardous Waste Center at 2440 West Sweetwater Drive and at collection sites throughout the city. For information, call 520-888-6947.

Don't put antifreeze down the drain. This will not protect your home's pipes from freezing in the winter.

What about medicines? How can I dispose of them safely?

Medicines should not be flushed. Many medications are not removed through the wastewater treatment process and can end up in the environment when discarded down drains. RWRD participates in the Dispose-a-Med Program.

If you cannot get to a Dispose-a-Med event, current recommendations are to grind medicines up with something like cat litter or coffee grounds to make them unusable, then throw them in the trash.

Should I flush disposable wipes?

Disposable Wipes Should Not Be Flushed! Disposable moist towelettes allow for the convenient clean up of sticky messes and are very handy during diaper changes. Another common use is to sanitize germy surfaces. Some manufacturers of disposable wipes indicate on the product’s packaging that the wipes are biodegradable and flushable. Because many of us are concerned about the environment, we want to buy products that are biodegradable; when we are told that we can safely flush a biodegradable product, it makes its use even more convenient.

Unfortunately, wipes rarely if ever biodegrade in the sanitary sewer system. However, their presence in the system can cause clogs and equipment failure in lift stations where mechanical pumps facilitate the conveyance of sewage in many areas of community. Additionally, if too many wipes accumulate in the sewer system, they can block pipes which can lead to the overflow of raw sewage into streets, buildings and the environment. When disposable wipes make it through the sewer system to a wastewater treatment facility, they are removed at the front end of the treatment plant and are taken to a landfill.

Pima County Regional Wastewater Reclamation asks that you do not flush disposable wipes down toilets. Instead, discard them in the trash. The proper disposal of these convenient and useful products will help keep our sewer system flowing properly, thereby ensuring the Department can safely contain, convey, and treat the community’s wastewater.

Can I discharge water from my swimming pool into the sewer? How?

Yes. Effective April 1, 2008, the discharge of swimming pool water into the public sewer system is generally authorized. For detailed information, see Swimming Pool Water Discharge Procedure  (revised July 1, 2015).

How can local businesses prevent grease discharges to the sewers?

Food Service Facilities (FSFs) are a significant source of fats, oil, and grease (FOG) because of the amount of grease used in cooking. The Pima County Grease Management Program was developed to assist restaurants and other FSFs with proper handling and disposal of their FOG. Specific guidelines aimed at helping business to keep grease from our sanitary sewer system can be found on the Preventing Grease Discharges into Sewers web page.
