Checklist – On-Site Wastewater Management Inspection
A drainage inspection is a systematic process of evaluating drainage systems to ensure the non-turbulent transit of wastewater from pipes to sewer systems. Performing a drain log is intended to prevent drainage problems such as cracks in the pipes, corrosion, freeze-ups, and major blockages caused by, among other things, tree roots, toilet paper build-up, or food waste.
Performance standards
1.1 Does the system prevent the spread of disease by microorganisms?
1.2. Does the system prevent the spread of bad odours?
1.3. Does the system prevent water contamination?
1.4. Does the system prevent degradation of soil and vegetation?
1.5. Does the system discourage insects and vermin?
1.6. Does the system ensure that people do not come into contact with untreated wastewater or effluents (treated or not) in their ordinary activities at the facilities in question?
1.7. Does the system minimize any adverse impact on facility amenities and surrounding grounds?
1.8. Do the systems provide for the reuse of resources (including nutrients, organic matter and water?

Sprinkler irrigation
3.1. Is the effluent disposal area more than 6m high/3m deep to driveways and property lines?
3.2. Is the effluent disposal area greater than 15 m up to the houses?
