Keep the file and protect the field
Know the layout, keep service records, watch alarms or changes, and keep heavy loads and drainage off the dispersal area.
Canadian onsite wastewater reference
Septic system rules made simple.
Start with the property itself: confirm sewer or onsite service, find the available records, locate the tank and dispersal area, then check the authority before work begins.

Own it, buy it or change the property.
The same system needs a different checklist depending on what you are trying to do.
Go beyond “it was pumped”
Confirm system type, approvals, condition, capacity, water supply and whether the intended use makes sense.
Resolve wastewater early
Bedrooms, additions, pools, driveways and construction access can affect capacity, setbacks and future repair area.
Regulation is provincial
125 local guides across 10 provinces.
City pages do not pretend every property uses septic. They start by asking whether the parcel is on municipal sewer, then route the reader to the current provincial and local authority.
National guides
Property questions explained clearly.
Written around real decisions: records, purchases, maintenance, failures and renovations.
How a Septic System Works
A conventional onsite system is not just a buried tank. Wastewater is settled or treated, then dispersed into soil where the site and system are designed to complete treatment.
Read guide →Septic Warning Signs: What They Mean—and What They Do Not
Slow drains, odours, wet ground and backups can point to an onsite system problem, but they can also come from a blocked building drain, pump failure or unusual water loading.
Read guide →Septic Maintenance Basics for Canadian Homeowners
There is no responsible universal pumping calendar for every property. Tank size, occupancy, water use, solids accumulation and treatment design all matter.
Read guide →Buying a Home with Septic in Canada
A septic purchase review should identify the actual system, records, condition and capacity—not just whether a hauler recently emptied the tank.
Read guide →Renovating a Home with Septic
Additions and site work can increase wastewater flow, reduce setback area or physically block the system. Check the septic implications while the project can still change.
Read guide →How to Find Septic Records in Canada
Record systems differ by province and municipality. The useful goal is the same: locate the system design, approval or filing, as-built information and later repairs.
