Arizona Seepage Pit Rule Requirements

The Arizona Administrative Code (state rules) state that seepage pits are only allowed in areas with “valley-fill sediments in a basin-and-range alluval basin.” (AAC R18-9-A311.B.1)

Alluvial basins are typically the areas within valleys that have been filled with hundreds of feet of fill soil washing down from the surrounding mountains.

These areas typically have groundwater several hundred feet below the surface so a seepage pit septic system will have plenty of soil to provide filtering and treatment before the water reaches the groundwater below.

ADEQ Online G.I.S. Map Shows Limits for Seepage Pits

The ADEQ website asks a user to enter the latitude and longitude for a site and optional Owner, Address, and Parcel number.

After the user clicks “Submit,” the Latitude and Longitude are used to locate the site on the G.I.S. map that also shows the boundaries of the basin and range alluvial areas.

The map appears with an X marking the project site and light orange or peach coloring for areas where seepage pits are allowed.
