The cost of a septic system depends on several factors: the type of treatment required, the size of the residence, and the labour involved in the installation. Only a licensed septic installer can provide an accurate quote.
To give you a general idea, the cost of a septic system with advanced secondary treatment for a three-bedroom home typically ranges from $30,000 to $50,000, depending on the region and the technology selected.

The ZENITH septic system consists of one or two tanks: the pretreatment tank and the biological reactor, sometimes combined into one tank. When there are two tanks, the primary reactor includes a pre-filter that helps prevent large pollutants from entering the next stage.
An external control panel, called the Bio-R, is installed near the tanks. It houses the aerator and a high-level alarm system.
The treated water is distributed into a leaching field—similar to a traditional drain field but about 60% smaller—for final soil infiltration.
Proper ventilation is essential for any onsite septic system. Depending on the terrain, a pump station may also be required—regardless of the treatment technology used.
