Pollution Prevention
Wastewater treatment plants, like those operated by the RDN, effectively treat sewage to standards set by provincial and federal regulating agencies so used water can safely return to the environment. Regulated standards target parameters like total suspended solids, biological oxygen demand, ammonia, toxicity, and bacteria.Click here to learn more about the wastewater treatment process and terminology.
Other chemicals that enter the wastewater may be removed because they have similar characteristics to targeted parameters. Still, most wastewater treatment facilities are not specifically designed to remove them all. Chemicals not removed by treatment will enter the environment.
Whether we live in an area serviced by sewer or have a septic system on our property, we all can prevent pollution. Preventing pollution before it happens is called Source Control. Source control is one of the most effective and economical ways to protect the environment and our natural resources. It also lessens the cost to maintain wastewater infrastructure. It is easy to follow these simple source control steps:
