Timing is useful information
Tell the person assessing the system whether wetness is constant, appears after rainfall or returns during snowmelt. Also note whether household drainage changes at the same time. These observations help frame the assessment; they do not prove the cause.
Northern Health’s subdivision checklist calls for seasonal high groundwater to be assessed and notes that this may require spring freshet observations. That makes seasonal site conditions relevant to local planning.
Avoid guessing at an excavation fix
A low-looking patch is not automatically a request for fill, and a wet field does not automatically need replacing. HealthLink BC advises keeping surface water away from onsite systems and seeking appropriate advice where water pools on a dispersal area.
If assessment identifies damaged buried piping or a field-replacement project, Tim can discuss the excavation requirements. Required design and specialist work should be clear before machine work is agreed.
Useful information for the project
- When the wetness started and how it changes through the season.
- Known tank, pipe and field locations.
- Recent excavation, vehicle traffic or drainage changes nearby.
- Photos taken from a safe location and existing system records.
- Any assessment that identifies a specific excavation scope.
