Engineering, Design & Permitting in Laurel, MT

We engineer wastewater systems for single-family homes, shops and garages with plumbing, multi-family properties, campgrounds, restaurants, and commercial facilities across the region. Engineering typically starts around $5,000 depending on project scope and complexity -- and bundling engineering with installation through TLC Patriot usually costs less overall than hiring a standalone engineering firm and then bidding out the construction.

TLC Patriot is the only septic company in the Billings area with an in-house engineering process. For residential and commercial wastewater and septic projects, one phone call covers engineering, design, permitting, and installation.

Our process brings site evaluation, design, permitting, and practical installation knowledge together. The design accounts for how the system will be built, the crew works from the permitted plan, and one accountable team handles questions throughout your project.

In Montana, every septic system needs to be engineered. Our team helps you understand the requirements for your property, including when it is not in an approved subdivision, when there is no certificate of supervision, and for all commercial and multi-family wastewater systems.

We review your parcel records, site conditions, and the applicable county requirements through our in-house engineering process. Call us to discuss the steps for your project before work begins.
