Septic System
On-site sewage systems, commonly known as septic systems, play a crucial role in managing wastewater in various regions of Ontario, Canada. These systems are designed to treat and dispose of domestic sewage from individual properties, ensuring the protection of public health and the environment. This write-up aims to provide a detailed overview of on-site sewage systems in Ontario, including their types, components, regulations, maintenance requirements, and environmental implications.
Types of On-Site Sewage Systems:
​
Conventional Septic Systems: The most common type, consisting of a septic tank and a leaching bed or drain field.
Advanced Treatment Systems: Enhanced systems that incorporate additional treatment components, such as aerobic treatment units or sand filters.
Holding Tank Systems: Temporary solutions that require regular pumping and disposal of the stored wastewater.
Components of On-Site Sewage Systems:
​
Septic Tank: A watertight container that receives raw sewage from households and separates solids, allowing the liquid effluent to flow into the drain field.
Drain Field: A network of perforated pipes buried in trenches, enabling the effluent to be dispersed into the soil for further treatment.
Distribution Box: A junction box that evenly distributes the effluent to different sections of the drain field.
Advanced Treatment Components: Additional equipment such as aerobic treatment units, sand filters, or UV disinfection systems that enhance the treatment process.
Regulations and Permitting:
​
Ontario Building Code: Provides regulations for the installation, design, and maintenance of on-site sewage systems.
Local Health Units: Responsible for issuing permits, conducting inspections, and enforcing compliance with regulations.
Environmental Protection Act: Establishes guidelines to ensure the proper management and protection of the environment during the installation and operation of septic systems.
Maintenance and Operation:
​
Regular Pumping: Septic tanks should be pumped every 3-5 years to remove accumulated solids and prevent system failure.
Inspection: Periodic inspections of the system, including the tank, distribution box, and drain field, are crucial to identify potential issues and ensure proper functioning.
Water Conservation: Conserving water usage helps prevent overloading the septic system, maintaining its efficiency.
Proper Waste Disposal: Avoid flushing non-biodegradable items, chemicals, or excessive amounts of medications, as they can disrupt the system's performance.
Advantages of on-site sewage systems:
​
Cost-effective: On-site sewage systems can be more cost-effective compared to connecting to a centralized sewer system, especially in rural areas where the cost of infrastructure development may be prohibitive.
Independence: On-site systems provide independence from centralized sewer systems, allowing property owners to manage their own wastewater disposal.
Flexibility: On-site systems can be designed to fit the specific needs of individual properties, considering factors such as soil conditions, property size, and water usage.
Less energy consumption: On-site systems generally require less energy for operation compared to centralized systems, as they do not involve extensive pumping and transportation of wastewater.
