Drain Field Installation & Repair in Billings, MT

Not every failing drain field needs replacement. Our first-line option for biomat-clogged fields is SludgeHammer remediation, which uses aerobic bacteria to digest the biomat and restore soil absorption -- with a 99.9% success rate and no excavation. For fields with physical damage, we repair crushed or separated lines, replace failed distribution boxes, and correct grading and drainage problems that send surface water into the field.

When replacement is genuinely the right answer -- collapsed trenches, exhausted soils, or a field that was undersized from day one -- our team designs the new field, handle county permitting, and our crews build it. You get honest advice about which path makes financial sense, backed by free estimates on all drain field work.

When a new or replacement drain field is the right answer, TLC Patriot coordinates the work through our in-house engineering process. Our team evaluates the soils, sizes the field to the applicable Montana DEQ and county requirements, and plans the trench layout. Our crews then excavate, install the distribution lines and media, and grade the finished site.

One company coordinates the project from soil testing to final inspection. We install conventional gravity fields where soils allow and evaluate pressure-dosed or SludgeHammer-assisted designs where conditions call for another approach.

A well-treated drain field can serve for decades. Pump your tank every 2-3 years so solids never reach the field. Keep vehicles, livestock, and heavy equipment off it -- compaction and crushed pipe are permanent injuries. Plant only grass over the field; tree and shrub roots seek out the moisture in the lines. Direct roof drains and surface runoff away from the area, and spread out heavy water use like laundry. These simple habits are the difference between a 15-year field and a 40-year field.

Your drain field (also called a leach field or absorption field) is where the real work of your septic system happens: effluent from the tank filters through the soil, which removes pathogens and nutrients before the water rejoins the groundwater. It's also the most expensive component to replace -- which is why protecting and restoring it is our specialty.

TLC Patriot provides comprehensive drain field services including repair, restoration, and new installation throughout the Billings area. As the exclusive distributor and installer of SludgeHammer Advanced Treatment in Montana, we can often remediate failing drain fields at a fraction of the replacement cost -- and when a new field truly is needed, our team uses the in-house engineering process to design and install it right.
