Help Stop Illegal Dumping into the Sewer System  

Did you know that dumping oil, fuel and solvents into the sewer harms the environment and can cause severe damage to your neighborhood?

Illegal sewer dumping has become an increasingly large problem in Phoenix. Offenders dump later at night or during low traffic times.

What happens?

The wastewater treatment plant may not be able to treat the water adequately leading to the discharge of solvents, fuels, and oils that can inhibit or kill the micro-organisms. These organisms are vital part of breaking down organic matter in the treatment process. It can also cause permit exceedances that can lead to the City of Phoenix to be fined by ADEQ or the EPA costs that could passed down to residents.

Who does it affect?

It affects everyone including worker safety. The sewer is not just a series of pipes. There are manholes, metering stations and sampling vaults that require employees to work in as confined space entrants. Fumes from fuels or solvents dumped in the sewer can be harmful to employees.

Why does it matter?

Wastewater treatment plants expend a lot more time, energy (electricity), and chemicals to treat wastewater containing fuel, oil, and solvents. The additional time needed to clean and treat illegally dumped substances is costly and can affect future costs for all residents.

What should be done?

All fuels, solvents and oils must be recycled or hauled off and disposed of by a licensed waste hauling company. For more information on hazardous waste management visit: http://www.azdeq.gov/hazwaste
