Septic Installation & Replacement in Rio Rancho

Rio Rancho has grown fast across its mesa-top terrain above the Rio Grande, and while the city's utility has extended sewer service to much of the core, plenty of established neighborhoods and newer growth areas on the outskirts remain on private septic systems. If your property is in Sandoval County outside city sewer lines, that includes you.

What's different about Rio Rancho's soil and terrain

The mesa terrain that gives Rio Rancho its long views also means variable soil conditions — some lots sit on sandy, reasonably fast-draining ground, while others encounter caliche or basalt-influenced soil closer to the escarpment edges. A percolation test on your specific lot is the only reliable way to know which situation you're in before designing a system.

Permitting in Rio Rancho

Rio Rancho and the rest of Sandoval County are permitted through the New Mexico Environment Department's local field office process, not the Bernalillo County ordinance that applies to unincorporated areas east of the river. See the full permit process guide for what that application looks like.
