Pollution Prevention

Pollution Prevention
Wastewater treatment systems are designed to make water cleaner than when it arrived, by removing some solids (primary treatment) and pathogens (secondary treatment and disinfection). They are not designed to remove all chemicals, drugs, and medications.

Whether you live in an area serviced by a sewer system or have an on-site septic system, you can prevent pollution. Preventing pollution before it happens is called source control. Source control will protect our natural resources and reduce maintenance costs to you and the community.

You can also learn about ways to prevent pollution by visiting our other websites: SepticSmart, Inflow & Infiltration, Team WaterSmart, RDN Get Involved.
