Commercial Septic Installation

Our commercial capabilities include:

  • High-capacity septic system design

  • Grease trap integration for restaurants

  • Lift stations and dosing chambers

  • Health department coordination and inspections

  • Collaboration with architects, engineers, and GCs

We help businesses in retail, hospitality, multifamily housing, and other industries install septic systems that support daily operations and long-term success.

Soil Testing and Custom System Design

Before a single shovel hits the ground, we start with a thorough site evaluation and soil analysis. Percolation testing, groundwater depth checks, and property measurements help us design a system that is efficient, durable, and tailored to your unique property.

Our system design process considers:

  • Soil absorption rate and texture

  • Topography and slope

  • Groundwater levels and setbacks

  • Water usage and daily flow rates

Only after full health department approval do we proceed — ensuring your system is permitted, approved, and perfectly suited to your land.

Modern Septic Technologies and Alternatives

Not every property is suited for a conventional septic system. Whether due to poor soil, tight space, or environmental limitations, we offer modern, eco-friendly alternatives that still meet code and perform reliably.

These advanced systems include:

  • Aerobic Treatment Units (ATUs)

  • Mound systems

  • Sand filters and peat biofilters

  • Drip dispersal systems

  • Timed dosing systems and effluent pumps

Our experts will help you select and install the right system to meet your needs, budget, and environmental goals — without sacrificing quality or compliance.

Final Grading and Property Restoration

After installation, we backfill and grade the site for proper drainage and safety. We can also restore lawns or install fresh landscaping to return your yard to its original beauty — or improve it. Our work is clean, careful, and built to last.
