Are you the owner of a septic system?


With the ongoing COVID-19 health emergency there has been an increased use of disinfectant and disinfecting wipes. These used products should go in the garbage and not down the toilet where they will negatively impact your onsite treatment, contribute to blockages and cause sewage backups.

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. Currently, septic systems serve about 26, 000 households in our region. If your system is working properly, it is an environmentally friendly and economically sound treatment option.
