Percolation Testing in Arizona

What Is a Percolation Test?

A percolation test — also called a perc test — measures how quickly water drains through the soil at your property. This test is required by ADEQ before a new septic system can be designed and permitted in Arizona. Without a passing perc test, you cannot get a septic permit.

When Do You Need a Percolation Test in Arizona?

• New home construction in areas without municipal sewer
• Adding a dwelling unit to an existing property
• Rural properties in Queen Creek, San Tan Valley, Maricopa, Cave Creek, New River and surrounding areas
• Properties in Maricopa, Pinal, Pima, Yavapai or Coconino Counties

Why Diaz Environmental for Percolation Testing

We own our own excavation equipment which means we can schedule, dig and test without waiting on subcontractors. This is how we consistently deliver results in 3–5 business days — faster than most competitors in the Valley.

We have extensive experience with Arizona soil conditions, including the rocky and caliche-heavy soils common in Maricopa and Pinal Counties that require specialized testing approaches.
