Full design, excavation & installation, done entirely in-house
Building new, adding an extension, or converting from a holding tank? We design and install a complete septic system—from site evaluation and drawings to septic excavation, tanks, treatment units, and leaching beds, so your home has a safe, code-compliant system that’s built to last. We handle permits/approvals, stamped drawings (where required), and inspections with your local authority so your project stays smooth. No bouncing between contractors. One team. One timeline.
Serving Quinte West, Belleville, Trenton, Prince Edward County, and surrounding areas.
When a new septic system makes sense
- New builds & infill homes that need a complete onsite system.
- Additions / secondary suites where increased bedrooms or plumbing fixtures change design flows.
- Holding tank conversions to a full septic/treatment system.
- Failed or undersized beds where septic rejuvenation isn’t viable.
- Change of use (e.g., short-term rentals) requiring capacity upgrades or advanced treatment.
What we install
Class 4 Septic Systems (conventional)
Two-compartment septic tank + distribution + leaching bed (stone-and-pipe or chambers), sized to design flow and site conditions.
Advanced Treatment Systems (tertiary)
Compact units that treat wastewater to a higher standard, ideal for tight lots, sensitive soils, or where reduced footprint is needed. We’ll specify the right technology for your site.
Raised/Constructed Beds
For shallow bedrock, high water table, or limited native soils. Properly engineered to protect groundwater and perform year-round.
Pumped/Dosed Systems
Timed dosing or pump chambers for elevation changes, pressure distribution, or equalized loading across the bed.
Replacement Tanks & Upgrades
Effluent filters, risers, alarms, distribution boxes, and bed expansions, future-proofed for serviceability.
Our septic system in-house process (design to backfill)
1. Site visit & evaluation – Measure lot features, assess soils and constraints (setbacks, water table/bedrock indicators).
2. Design & drawings – Determine design flow, tank size, treatment unit (if required), and bed type/footprint; prepare permit package.3. Permits & coordination – Submit to local authority, coordinate inspections, utility locates, and schedule neighbors/traffic as needed.
4. Excavation & installation – Tanks set level, bed constructed to spec (media, trench depth, distribution), pumps/controls wired and tested.
5. Commissioning – Verify flows, alarms, dosing, and final grading/drainage to protect the bed; homeowner orientation.
6. Handover – As-built notes, maintenance schedule, and warranty.
