Wastewater Systems Built to Last Decades

Installing a new septic system requires careful site evaluation, proper tank sizing, and drain field design that matches your property's soil type and groundwater level. In Kalispell, where many homes sit on larger lots outside municipal sewer service areas, your septic system handles all household wastewater quietly and efficiently when installed correctly. 406 Innovative Solutions provides complete septic system installation, from soil percolation testing to final inspection, ensuring your system meets local health codes and functions reliably for decades.

We install concrete and fiberglass septic tanks, design leach fields based on soil absorption rates, and handle all excavation, pipe placement, and backfilling. Each septic installation begins with a percolation test to measure how quickly water drains through your soil, which determines drain field size and layout. We also install distribution boxes, risers for easy access, and effluent filters to protect the drain field. Our septic contractors work with local inspectors to ensure every installation in Kalispell meets county regulations and receives final approval before the system goes live.
