From Health Hazard to Backyard Oasis

Mound Replacement Project

A failed mound system that consumed the entire backyard and created a public health hazard — completely resolved with a Hoot H600 BNR and Geoflow drip dispersal

The Problem:


Imagine your entire backyard taken over by a mound septic system. Now, imagine that mound failing. These homeowners didn't have to imagine it — they lived it.

After settling into their dream home for just a few years, the mound system failed. The contaminated system wasn't just an inconvenience. Yolo County Environmental Health inspected the property and immediately declared the site a public health hazard, requiring action without delay.

What Yolo County Required

    • Complete removal of the failed mound system
    • Full site remediation — scraped down to bedrock
    • Removal of all contaminated soil to a county-approved disposal site
    • County inspection and sign-off before any new system could be installed

The remediation was extensive. The entire backyard was scraped to bedrock, and every trace of contaminated soil was hauled away. Only after Yolo County Environmental Health approved the cleared site could the new system go in.

Health Hazard Notice: When a septic system fails in Yolo County, the Environmental Health department can issue immediate remediation orders. This family was required to act fast — and conventional replacement wasn't an option given the site constraints.

 

The Solution:


 

Why Not Just Replace the Mound?

A new mound would have required another massive footprint in the backyard — and the site conditions that caused the first one to fail hadn't changed. The Hoot H600 solved the problem permanently in a fraction of the space.

Once the site was cleared and approved, the team installed the Hoot H600 BNR Advanced Septic Treatment Tank — a self-contained, single-tank system that handles all wastewater treatment in one compact in-ground unit.

The homeowners chose the Hoot for three compelling reasons:

  • Space savings — one tank, one excavation, no mound
  • Cost — less expensive than competing advanced systems
  • Speed — days to install, not weeks

For the dispersal field, the team utilized Geoflow Wastewater Drip Tubing, installed just 8 inches below grade. Because the Hoot's effluent quality is so high, it can actually be used to help irrigate the landscaping — adding real value to the property while solving the wastewater problem.

The End Result

The health hazard was eliminated. The contaminated soil was gone. The mound was gone. And the family finally had their backyard back — for the first time since moving in.
