What Does Septic Tank Installation in Woodburn Involve? 

Septic tank installation is a multi-phase process that starts with a site evaluation and ends with a final county inspection. Properties in and around Woodburn fall under Marion County jurisdiction, where the Oregon DEQ and the county environmental health office jointly govern permit requirements. Soil conditions in this part of the Willamette Valley range from silty loam near the Pudding River corridor to heavier clay soils toward Hubbard and Mount Angel. Those differences directly affect drain field design and which system type your lot may qualify for. Every installation Ace Septic & Excavating Inc. handles is tailored to the specific soil profile, lot size, and household load of that property. 

Our Septic Installation Process 

Ace Septic & Excavating Inc. follows a clear, step-by-step approach to keep your project on track from the first shovel to final sign-off. 

1

Site evaluation and soil testing to assess absorption capacity and determine the right system type. 

2

Permit application and approval through Marion County environmental health and Oregon DEQ before any excavation begins. 

3

Excavation of the tank area and drain field trenches, with attention to protecting landscaping and utility lines. 

4

Tank placement and connection, including inlet and outlet baffles, risers, and lids positioned for safe long-term access. 

5

Drain field installation and final inspection, confirming the system meets Oregon code requirements before backfilling. 

Conventional Systems vs. ATU/Aerobic Systems 

Conventional gravity-fed systems are common on properties with adequate soil absorption and remain the most straightforward option for many Woodburn-area homeowners. When percolation is limited or a lot lacks space for a standard leach field, an alternative treatment unit (ATU) or aerobic treatment system may be required. ATUs provide a higher level of treatment before effluent reaches the drain field, making them a workable solution on challenging sites. Ace Septic & Excavating Inc. works with both system types and can help you understand which option Marion County is likely to approve for your parcel. 


Permits and Site Requirements in Marion County

Oregon requires a site evaluation permit before any septic work begins. Marion County environmental health staff review the site assessment, soil log, and proposed system design before issuing an installation permit. The installer must be licensed with the Oregon DEQ, and the completed system must pass a final inspection. Ace Septic & Excavating Inc. has navigated Marion County's permitting process since 1989, serving communities from Woodburn and Hubbard to Silverton and Stayton.

  • How Long Does Septic Tank Installation Take?

    Most residential installations are completed in one to three days once permits are approved. The total timeline from site evaluation to final inspection may span several weeks depending on Marion County's permit and inspection schedule. 

  • Do I Need a Permit for a New Septic System in Woodburn, OR?

    Yes. A permit is required before any installation work begins in Woodburn or anywhere in Marion County. Oregon DEQ requires a licensed installer, and the completed system must pass a final inspection. 

  • How Do I Know if My Property Needs a Conventional or ATU System?

    A licensed installer performs a soil evaluation to determine which system type your lot can support. Properties with slower absorption or limited drain field space may require an ATU, while lots with good percolation typically qualify for a conventional gravity system. 

  • Can I Get a Septic System Installed on a New Construction Property?

    Yes. Ace Septic & Excavating Inc. works with property owners and builders during the planning phase to coordinate site evaluation, permitting, and installation for new construction in the Woodburn area.
