Septic systems are an important wastewater treatment option for homeowners in the capital region. Also known as onsite wastewater treatment systems, they provide household disposal of wastewater where sewers are either unavailable or too expensive.

If your system is working properly, it is an environmentally friendly and economically sound treatment option. If it's not working properly it can cause environmental issues and health issues in our community.
