ABOUT ON-SITE SEPTIC AND EXCAVATION

Turning backwards problems
into forward solutions.

On-Site Septic and Excavation is based in Salem, Oregon, and serves Linn, Benton, Lane, Polk, Marion, and Yamhill counties. We specialize in septic systems, excavation, underground utilities, and site infrastructure for residential, commercial, and rural properties.

THE WAY WE WORK

Understand the problem.
Build the right solution.

Our company was built around a simple idea: understand the problem, develop the right solution, and do the work right.

With an engineering background and extensive experience working with complex water and wastewater systems, owner Kiel Brown brings a technical approach to excavation and utility construction that is uncommon in the industry. That experience allows us to look beyond simply moving dirt or installing pipe. We consider how the entire system needs to function—from site conditions and hydraulics to installation, accessibility, and long-term reliability.

Our work ranges from residential septic repairs and replacements to larger decentralized wastewater systems and commercial site infrastructure. We have experience installing and connecting sewer systems, performing excavation and underground utility work, and providing stormwater collection and conveyance for commercial sites.

Whether we're replacing a failing drain field, installing a new septic system, connecting a property to a sewer system, constructing commercial stormwater infrastructure, or taking on a difficult excavation project, we approach each job with the same attention to detail and problem-solving mindset.

Locally owned.
Directly involved.

As a locally owned and operated company, we take pride in being directly involved with our projects. We believe the people responsible for the work should understand the project, communicate with the customer, and stand behind the finished product.

We work with homeowners, property owners, contractors, engineers, and other professionals to turn plans and challenging site conditions into properly constructed, functional infrastructure.

WHAT DRIVES US

We're not interested in simply moving dirt.
We're interested in building solutions that work.
