What a new system includes
A septic system is two main parts: a septic tank that holds solids, and a drain field (leach field) where the liquid soaks into the soil and gets treated. Connecting pipe, a distribution box, risers and lids tie it together.
The process, start to finish
- Site visit. We look at the lot, the house plans or existing home, the well location and the slope.
- Soil and site evaluation. Soil type, depth to rock or caliche, and other site conditions decide what kind of system fits. See site evaluations.
- Design and permit. The system is sized for the home and submitted to the New Mexico Environment Department (NMED) for a permit. See permits.
- Excavation. Tank hole and drain field trenches dug to the approved layout.
- Tank and field installed. Tank set level, pipe laid at the right slope, field built with gravel or chambers.
- Inspection. The system is inspected before it's covered.
- Backfill and grade. Covered, graded to shed water, risers brought to the surface.
Edgewood ground
Soil around Edgewood and the Estancia Valley edge varies a lot from lot to lot — sandy in some places, clay in others, with caliche or rock in spots. That's why the site evaluation comes first: it decides whether a standard gravel field works or something else is needed.

Septic questions
How long does a new septic installation take?
Once the permit is approved, installation is often a few days, depending on the system and soil. Permitting time varies.
Do I need a permit?
Yes. New Mexico requires a permit from the Environment Department for septic systems.
How big a tank do I need?
Tank and field size are based on the home's size (usually bedrooms) and state rules.
Can you work with my builder?
Yes — we coordinate with builders and other trades on new homes.
