Why valley lots are different
Corrales stretches along the west side of the Rio Grande, from the bosque up to the base of the Rio Rancho escarpment. Near the river, groundwater can sit closer to the surface. Irrigation ditches run through the village. Most homes have their own well. Every one of those things affects where a septic system can go and what kind it needs to be.
What a new system involves
- Site visit — the lot, the house or plans, the well, ditches and slope.
- Soil and site evaluation — soil type and the depth to groundwater. See site evaluations.
- Design — conventional or advanced treatment, sized for the home.
- State permit — through the New Mexico Environment Department. See permits.
- Installation — tank, distribution and field built to the approved plan.
- Inspection — before anything is covered.
- Backfill and grading — risers brought to the surface.
Conventional or advanced?
On higher ground with deeper soil, a conventional tank and field may be all that's needed. Closer to the river, on smaller lots, or where groundwater is shallow, the rules may call for more treatment. See groundwater and septic.
