Who you'll talk to

Natasha owns the company and draws the systems herself. She walks the site with you, has the soil evaluated, submits the design to the Yakima Health District and is present at inspections. Around her are the people customers name in their reviews.

If you are starting from nothing, begin with septic system site design. If something already in the ground has failed, the repair page is the place to start.

Signed off by the Health District

“The Health District approved the design with no comments. I spoke with a specialist at the Health District, and he told me they think highly of system designs Natasha produces, and that I should not expect any issues (there were none).”

The second opinion

Mike Durbin's drain field failed. A local company that did “minimal site exploration” quickly decided the fix needed a very expensive pressurized system. He called us for a second opinion.

Our willingness to explore a larger area of his property, “2 acres to test and perk,” saved him “over $20,000 in costs.” The system type follows the soil, and the soil gets looked at before anything is priced.
