Septic Installation & Replacement in Placitas & Bernalillo

Placitas sits in the foothills of the Sandia Mountains' north end, where large custom-home lots are the norm and municipal water and sewer service is patchy at best — most properties rely on private wells and septic. A few miles west and down in elevation, the town of Bernalillo sits closer to the Rio Grande, with different soil and a more traditional small-town lot pattern.

Two different soil pictures in one service area

Placitas properties often sit on decomposed granite and rockier foothill soil, with drainage that can vary sharply across a single large lot depending on where you test. Properties closer to Bernalillo and the river valley tend toward sandier, alluvial soil, though caliche layers still show up throughout the area. Neither profile is uniform enough to design from assumption — a percolation test on your specific building site is essential in both areas.

Water quality context worth knowing

Many Placitas-area properties draw from private wells with notably hard water, and proper separation between wells and septic components is taken seriously in permitting review here for exactly that reason. If you're planning a new well alongside a new septic system, coordinate the site plan for both at the same time rather than sequentially.

Permitting in Placitas & Bernalillo

Both areas fall under Sandoval County, permitted through NMED's local field office process. See the permit process guide for the full application requirements.
