We KEEP Your Mission HOME Running Smoothly
Septic Tank CLeaning in Mission
Mission properties rely on hardworking septic systems, especially in areas with heavy clay soils, sloped terrain, and high seasonal rainfall. We deliver thorough septic tank cleaning to help your system run efficiently, reduce the risk of backups, and extend its lifespan. Remove accumulated sludge and scum so your tank can operate the way it’s meant to.

Septic Tank Cleaning
How your septic system works
Over time, every septic tank gradually builds up two layers: a dense sludge layer at the bottom and a floating layer made of grease, fats, and lighter materials at the surface. If these layers get too thick, they can wash into the drain field and cause clogs, soggy patches, or even system failure. Regular cleaning protects your drain field, prevents expensive repairs, and keeps your Mission property safe and sanitary.

Emergency response
1. Initial Assessment
We locate and uncover your septic tank, examining the lid, access points, and visible structural features.
2. Tank Opening and Inspection
Once opened, we measure the thickness of the sludge and scum layers to determine the level of cleaning required.
3. Pumping and Cleaning
Using professional pumping equipment, we remove all waste materials efficiently and leave the tank clean and ready for proper bacterial regrowth.
4. System Inspection
Our technicians inspect inlet and outlet pipes, baffles, and other components to identify any damage or potential flow restrictions.
5. Refill and Close
The tank naturally begins re-balancing its bacterial ecosystem once cleaned. We close and seal the lid securely.
6. Final Review
We tidy the work area and provide you with a summary of findings along with future maintenance recommendations.

Delays can lead to drain field oversaturation, backups, environmental contamination, and costly repairs.
Homes with larger tanks or fewer residents may need service every 3–5 years. Older systems, high-usage households, and properties with challenging soil may require cleaning more frequently.
Mission homeowners must follow provincial guidelines set by the BC Ministry of Health. Regular maintenance is required to prevent contamination of groundwater and nearby waterways.
Slow drains, gurgling pipes, sewage odours outdoors, or wet patches in the yard are all signs your tank may be overdue for service. Properties on slopes or with clay soil may notice symptoms earlier.
