Septic tank pumping and maintenance scheduling
Pump-outs, filters and risers, scheduled from the filed maintenance plan.
Nanaimo Septic Systems pumps and services septic tanks. Most tanks need pumping every 3 to 5 years, and that is what the Regional District of Nanaimo advises for yours. Your system also carries a maintenance plan, filed under the Sewerage System Regulation alongside the Letter of Certification, and it sets out what your system needs and how often.
Servicing is the cheapest part of owning an onsite system. Pumping your tank on schedule is what protects the disposal field.
Pumping is priced on tank size, access and haul distance to a receiving facility, and those three vary more than the work itself does. A property with risers at grade near a main road and an island property with buried lids are not the same job.
What sets the interval
Tank size, household size, whether you run a garburator, and whether an effluent filter is fitted all change how often your tank needs pumping. Where a system has its own filed maintenance plan, that plan sets the interval.
The maintenance plan is part of the filing
A maintenance plan is filed with the Letter of Certification within 30 days of a system being completed, which means most systems filed under the current regulation already have one. Type 2 and Type 3 systems carry more in that plan than a Type 1 does, because treatment components need servicing on their own schedule to keep producing effluent at the standard the system was filed to.
Risers, filters and getting to the lid
Buried lids are the usual reason servicing gets put off. Access risers bring the openings to grade and are rebated by the Regional District of Nanaimo at 75% of eligible expenses up to $400, with effluent filters rebated up to $100 and distribution boxes up to $200.
Servicing quoted
Tank pump-out
Tank emptied with baffles and outlet checked while access is open.
Effluent filter service
Filter cleaned or fitted where none exists, to keep solids out of the field.
Riser installation
Lids brought to grade so future servicing does not start with a shovel.
How servicing is scheduled
- 1
Records check — the filed maintenance plan and any pump-out history set the starting point.
- 2
Locate and open — lids found and brought to grade where risers are missing.
- 3
Pump and inspect — tank emptied, baffles and effluent filter checked while access is open.
- 4
Record and schedule — what was found written down, and the next interval set from it.
Wells and bedrock on Gabriola
Gabriola Island is the clearest case. Most households there draw from individual wells in fractured bedrock, and a growing number now top up with rooftop rainwater. Groundwater flow through those fractures is complex enough that percolation and water supply are both known problems on the island. Most lots there carry both a well and a septic system on the same ground.
A typical case
- Situation
- A Gabriola Island household on rainwater catchment with a 20-year-old tank and no pump-out records.
- Complication
- Both lids sit roughly 0.5 m below a gravel parking area added years earlier.
- Resolution
- We bring the risers to grade, fit an effluent filter at the outlet, and record a 3-year interval against the property.
People also ask
How often should a septic tank be pumped?
The Regional District of Nanaimo advises every 3 to 5 years for most tanks. A system with a filed maintenance plan follows that plan.
What happens if a tank is never pumped?
Solids carry over into the disposal field and clog the soil interface. We pump the tank and check the field before deciding what needs doing.
Do septic lids have to be at ground level?
Older systems often do not have access risers. Bringing your lids up to ground level makes the tank far easier to service, and the Regional District of Nanaimo rebates 75% of eligible expenses up to $400 for the work.
Is pumping included in a maintenance plan?
A maintenance plan filed with the Letter of Certification sets out what the system needs and at what interval, which for most systems includes the tank.
Servicing connects to three other things: an inspection report, drain field repairs, and the cost guide.
Septic service on Gabriola Island is covered separately.
