What the ground in Rio Rancho is like

The USDA soil survey rates mapped ground in Rio Rancho for septic drain-field suitability across roughly 103 square miles. About 37% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Rio Rancho, the leading limit is filtering capacity: the soil does not clean effluent thoroughly enough on its way through. A drain field is a treatment system as well as a disposal path; when the ground cannot filter well, pathogens and nutrients travel farther than the survey allows. The survey flags that limit on about 36% of the rated ground here.

The limiting features the survey records most often here:

• Filtering capacity36.3%
• Slow water movement30.8%
• Slope15.9%

This is survey data for mapped areas, not a substitute for a site evaluation on your own lot. Conditions on a single parcel can differ from the map.
