Excavation for engineered onsite wastewater systems on commercial, institutional, and camp projects. Tank holes, distribution fields, and servicing trenches cut to the designer's spec and ready for health-authority inspection. Your ROWP installs the system — we put the ground exactly where the design needs it.
We work with the project's ROWP and the engineered design. The ROWP specifies the tank location, depth, and field layout — we dig it. The CAT 305 excavates the tank hole to depth, trenches the distribution field to grade, and places bedding material where the spec calls for it.
Tank holes get cut clean with vertical walls and a flat bottom. Distribution field trenches hold their grade across the full run — no high spots, no low spots, no pooling. When the ROWP lays pipe, every joint drains the way it's supposed to.
After the ROWP finishes and the inspector signs off, we backfill in lifts with proper compaction and do the final site grading. The goal is a finished surface that drains away from the field area and leaves no sign of where the system went in — except the risers.
We've done enough wastewater excavations in the Cariboo to know the typical soil conditions, frost depths, and setback requirements. We show up with the right bucket, dig to the right depth, and leave the site ready for the inspector.
Full excavation for engineered onsite wastewater systems serving shops, offices, and institutional facilities. Tank hole, distribution field, bedding, backfill, and final grading.
Excavation for camp and remote-site wastewater systems where municipal servicing doesn't reach. Coordinated with the ROWP and the site schedule.
Excavation for system upgrades and replacements. We remove the old and prep for the new.
Excavation for holding tank systems on sites where a conventional field isn't feasible.
Onsite wastewater and civil servicing excavation for commercial and institutional clients across the Cariboo — 100 Mile House, Williams Lake, Lac la Hache, and surrounding communities.
We dig the tank hole, the distribution field trenches, and any connecting pipe runs to the specs provided by the project's ROWP or designer. We also handle backfill and final grading after the system is installed. We do the earthworks — the ROWP does the actual system.
We do the excavation side only. We dig to spec, the project's ROWP places the tank and distribution system, and then we backfill and grade.
A standard system excavation is typically a 1 day job. Larger engineered systems, rocky ground, or difficult access can push it to 2 days. We coordinate with the ROWP so everything happens in sequence.
