Septic System Design

(416) 436-5488

Headwaters Construction can complete the design and permitting of both new and replacement septic systems for residential, commercial, industrial, institutional, and recreational (i.e., campgrounds or parks) uses.  We have ability to have both standard and state-of-the art septic systems designed and constructed, including unique systems that will work with challenging property configurations.

Trust the Professionals

Our septic system designs are prepared by licensed Professional Engineers with over 30 years of experience in both design and construction.   Our “hands-on” construction experience ensures that our designs:

• Are cost-effective

• Minimize septic system “footprint”

• Use best available technologies

• Protect the environment

Plan for the Future

Special design considerations include planning for future property changes to allow for:

• Pools

• Cabanas, Sheds, Garages/Workshops

• Building Renovations and Additions

• Addition of Buildings Plumbing Fixtures (i.e., addition of washrooms or kitchens or sinks)

• Addition of a Business or Change in Building Use

Septic System Permitting

Headwaters Construction understands the permitting process for all types of septic systems, and applicable municipal and provincial codes and regulations.  We continually work with:

• Municipalities

• Regions

• Counties

• Conservation Authorities

• Ministry of Environment, Conservation and Parks

• Ministry of Natural Resources and Forestry

• Niagara Escarpment Commission

Headwater Construction also routinely works with engineering and environmental consulting firms and can bring expertise to your project to help you through the design and permitting process.

Frequently Asked Questions: Septic System Design

  • Headwaters Construction offers complete design and permitting for both new and replacement septic systems, serving residential, commercial, industrial, institutional, and recreational properties like campgrounds. Their designs, prepared by licensed Professional Engineers with over 30 years of experience, incorporate hands-on construction knowledge to ensure cost-effective, minimized footprint systems using best available technologies while protecting the environment.

  • Headwaters Construction designs septic systems with long-term scalability in mind, discussing clients' goals like family expansions, workshops, or rental units to create compliant, efficient plans that reserve space for future additions. Their 30+ years of Engineering experience maps optimal locations for current and future components, safeguarding investments for decades.

  • The process starts with site evaluation, including soil testing and percolation analysis to determine daily design flow, tank sizing, and drain field layout based on projected water usage and soil absorption. Engineers then develop detailed plans considering topography, setbacks, and regulations, followed by permitting with municipalities, conservation authorities, and provincial ministries.

  • Soil testing, including percolation tests, assesses absorption rates to ensure safe effluent dispersal, protecting groundwater and wells while informing tank dimensions and leaching field design. Headwaters' professional engineers use this data for precise, environmentally responsible systems suited to challenging sites.

  • They handle standard and state-of-the-art systems, including advanced treatment units (ATUs) that treat wastewater more effectively for smaller footprints and less excavation on difficult properties. Designs adapt to unique configurations, prioritizing low-impact technologies aligned with site conditions.

  • Through meticulous pre-construction planning like terrain mapping and soil profiling, they minimize disruption with precision excavation, layered backfilling, and grading to restore natural contours and drainage. Their integrated design-build oversight by in-house Engineers guarantees compliance, system longevity, and reduced environmental impact during construction.
