1) Initial Call and Site Review

You begin by describing symptoms—slow drains, soggy patches, or frequent pumping. A site visit confirms the basics: tank location, existing field footprint, slope, setbacks to wells and property lines, and any surface drainage issues.

2) Soil and Seasonal Water Evaluation

Next comes the critical investigation. Test pits or probes identify soil texture, structure, and limiting layers. Seasonal high water table indicators guide trench depth and type. These findings drive the design: conventional trenches where soils percolate well, pressure dosing for uniform distribution, or elevated mounds in shallower soils.

3) System Design and Sizing

With flows based on bedroom count and fixture load, the designer selects the treatment area style and layout. Setbacks to wells, buildings, and waterways are plotted. Distribution boxes or manifolds are oriented for level flow. Materials are specified—chambers, pipe, fabric, sand media—and a plan set is drafted for submission.

4) Permitting and Scheduling

Designs are submitted to the appropriate authority for review. Once approved, the project is scheduled around weather windows and material lead times. Utility locates are called in. Erosion controls and construction access are planned.

5) Decommissioning the Failed Field

The old field is isolated from the tank to prevent cross-contamination. Unsuitable materials are removed or abandoned per code. If root intrusion, grease clogging, or biomat overgrowth is discovered, those conditions are documented so habits or fixtures can be adjusted going forward.

6) Excavation and Installation

The new field is excavated to design depth with laser-accurate grading. Trenches are bedded as specified, laterals placed level, and inspection points installed. Pressure systems are tested for head and even distribution.

7) Inspection, Commissioning, and As-Builts

The inspector verifies setbacks, materials, distribution, and elevations. After approval, you receive as-built drawings, operation guidance, and maintenance schedules. Landscaped areas are restored, and any traffic-rated surfaces are compacted and finished.

What Influences Cost in Idaho

Costs reflect design type, soil conditions, depth to limiting layers, access, and restoration. Mounds and pressure dosing add components but provide reliable performance where soils demand it. Tight sites may require smaller equipment and more handwork. Driveways, fences, patios, and mature landscaping can affect labor and restoration. Transparent estimates should separate design, permits, materials, excavation, rock or sand import, restoration, and contingencies, so you see exactly where the budget goes.

How to Get the Best Outcome

Communicate honestly about water use: number of bedrooms, occupancy patterns, large tubs, water softeners, or laundry habits. Plan for future expansions or an accessory dwelling unit so the field has capacity. Keep heavy vehicles off the absorption area and redirect roof and surface water. Schedule routine tank pumping and add inspection ports to make maintenance fast and affordable.

Add simple protections that extend system life: route roof downspouts away from the field, fix leaky fixtures, spread laundry over the week, and keep deep-rooted trees outside the footprint. In winter, avoid snow compaction that forces frost deeper. In summer, mow but skip heavy aeration over laterals. Mark the field on your site plan, and share it with future owners. Small habits like these safeguard trench biomat health and help your new Idaho system run.
