What Is a Septic System?

A septic system is an on-site wastewater treatment system that processes household wastewater. It consists of two main components:

Septic tank: A buried underground tank that temporarily holds wastewater.
Drainfield: A system of perforated pipes that disperses treated wastewater into the soil.

In Ontario, septic systems are required for properties not served by municipal sewers. Proper design and installation are crucial for environmental protection and system longevity.

Types of Septic Systems in Ontario

Ontario recognizes several types of septic systems, each with different designs and capacities:

System Type	Description	Typical Capacity
Conventional	Most common type with separate tank and drainfield	Up to 1,000 gallons
Indirect	Uses a leach field with a distribution box	Up to 1,500 gallons
Aerobic	Uses oxygen to treat wastewater	Up to 2,000 gallons
Mound	Elevated tank with a small drainfield	Up to 500 gallons

The appropriate system type depends on your property's size, soil conditions, and local regulations.

Factors Affecting Septic System Costs

Several factors influence the cost of installing a septic system in Ontario:

Property size: Larger properties require larger systems
Soil type: Sandy soils may require additional treatment
System type: Aerobic systems are more expensive than conventional
Permits: Required for all installations
