KNOW THE BASICS: WHAT ARE OVERFLOWS? THE BASICS

When it rains or snow melts, excess water can overload the sewer system resulting in discharges of diluted, untreated wastewater that contains sewage and other contaminants to overflow into the area’s rivers, streams and creeks. When that occurs, people are advised to avoid direct contact with river water.

While our region’s waterways are much cleaner than in the past, they still are polluted by discharges of diluted, untreated wastewater that contains sewage during overflows, which violate the Clean Water Act. If our region does not significantly reduce the number of overflows, it faces major fines and deterioration of our water quality.

ALCOSAN, municipalities and homeowners all play a significant role in solving this problem. In addition to planned system improvements and expansion of treatment capacity at the ALCOSAN plant, our customer municipalities are under individual Consent Order to reduce excess stormwater from entering the system.

TAKE ACTION: HOW CAN I HELP FROM MY PROPERTY? Take Action

Keep clipped grass, leaves 
& yard debris away from 
storm drains.

Don’t plant trees near the sewer lines to prevent 
pipe-damaging roots.

Capture water in a rain barrel 
& reuse it to water plants.
(If your community permits it.)

Use water-efficient 
landscaping to 
absorb stormwater.

Avoid landscaping 
near sewer lines to 
prevent blockages.

Wash cars at a 
car wash rather than 
in the driveway.
