The Function of a Residential Drainage System
A septic system safely treats household wastewater, preventing contamination of soil, groundwater, and local water bodies. Systems typically consist of:
- Septic tank: Collects and separates solids from liquids.
- Drainfield or leach field: Allows filtered water to seep into the soil.
- Soil absorption: Natural process that treats the effluent.
Proper installation ensures longevity, reduces repair costs, and maintains local environmental standards.
Determine Your Property’s Suitability
Before installation, consider:
- Soil Testing: A percolation test determines how quickly soil absorbs water. Sandy soil drains quickly, while clay-heavy soil may require a specialized system.
- Site Selection: Keep your septic system at least 30 meters from wells, streams, or lakes to prevent contamination.
- Local Regulations: Douro-Dummer and Ontario municipalities have specific guidelines, including permits, tank size requirements, and setbacks.
Pro Tip: On-site soil testing is essential to confirm that the system will operate efficiently and meet all municipal requirements. Taking this step early helps ensure long-term reliability.
Choosing the Right System
There isn’t a one-size-fits-all septic system, which means homeowners can choose the option that best matches their property and lifestyle.
- Conventional Gravity Systems – Ideal for many standard residential lots, these systems are straightforward, reliable, and easy to maintain.
- Mound Systems – A smart solution for properties with challenging soil conditions, offering flexibility in placement while maintaining strong performance.
- Aerobic Treatment Units – Perfect for households with higher water usage, these systems deliver faster treatment in a compact design and provide consistent, dependable results.
Selecting the right system influences both cost and longevity. A qualified installer can recommend the best solution by considering soil conditions, property layout, and household needs.
