Ontario septic tools
Two working tools, 100% client-side — nothing you enter leaves your browser. Use the calculator to anchor the money conversation, and the checklist to keep the contractor conversation honest.
Septic system cost calculator
System type, bedrooms, soil and lot constraints in — an indicative CAD planning range out, with a printable summary for quote meetings. Bands trace to published Ontario installer guides (conventional CAD 15,000–35,000; advanced CAD 35,000–65,000).
Installer vetting checklist
Twelve weighted checks — OOWA standing, qualified designer, insurance, itemisation, warranty, payment schedule — with an A–D grade and a copyable report for each quote.
