General information only — not legal, tax, financial, or real-estate advice. Verify with a licensed BC professional before acting.

A septic system is an onsite sewage disposal system used where municipal sewers are not available. In BC, septic systems are regulated under the Sewerage System Regulation (BC Reg. 326/2004) enforced by regional Health Authorities. Systems are classified as Type 1 (septic tank + gravity field), Type 2 (adds treatment before discharge) or Type 3 (highest treatment level, used on difficult sites). New systems and material alterations must be designed by a Registered Onsite Wastewater Practitioner (ROWP) or professional engineer, and a filing must be made with the Health Authority. Consumers buying a rural property typically order a septic-system inspection during subject-removal.
