In Corrales, the Sale Is When the Septic, Sewer and Well Questions Come Due

In most of the Albuquerque metro, a utility company keeps track of where a house's water comes from and where its wastewater goes. Corrales has no municipal water system serving homes. Most homes, farms and businesses run on private wells and septic systems, and the village's only sewer is a small STEP system. That system, which the village started building in 2009, runs along Corrales Road. So a sale is when the state and the village look at a property's systems, and when a buyer learns what they are inheriting. Below are the four checks that come up during a Corrales sale, roughly in the order they appear.

The Septic Evaluation Starts a Two-Week Clock

New Mexico requires the person transferring a property with an established on-site liquid waste system to have that system evaluated before the transfer. A qualified evaluator does the work on a form the department has approved. Since almost every Corrales home has a septic system, this step applies to nearly every sale in the village.

The NMED property transfer guidance sets out the steps:

1. Find the system's permit number and ask the local NMED field office for a copy of the permit file.
2. The evaluator inspects the system and sends the report to NMED within 15 days. Every report must be filed, including incomplete ones.
3. NMED charges a $50 fee before it date-stamps the report as received. The stamped report then becomes an official record used in the transfer.
4. Whoever owns the property on the 15th day after the evaluation must apply for a permit or variance within 15 days to fix any deficiencies the evaluation found.
5. Advanced treatment systems and holding tanks have to be transferred into the new owner's name, with a new maintenance and sampling contract. Conventional systems without holding tanks need no ownership paperwork.

Step four matters most for the deal. The obligation to fix problems falls on whoever owns the property on day 15, so where the evaluation lands relative to the closing date decides whether the seller or the buyer is on the hook for corrective permits. In Corrales, the purchase contract should settle that timing.

Unpermitted systems are their own problem. If neither the owner nor NMED can find a permit, the system counts as unpermitted. It can be registered if it passes an inspection by an NMED inspector or an installer specialist. If it fails, the owner has to get a permit to fix it. On an older Corrales property, the permit search can matter more than the inspection itself.

On Corrales Road, Closing Triggers the Sewer Hookup

The village sewer has a defined primary service area, the Corrales Road Commercial Area. Properties elsewhere can get service where capacity allows, if a line runs within 300 feet and a connection point exists. Inside the primary area, Ordinance 14-09 lists the events that require an owner to apply for connection right away. The third one is the one that affects sales:

"The property is sold or otherwise transferred to a new owner; provided, however, that this provision shall not apply to the transfer of property to a new owner in probate by the will of a decedent, by transfer on death deed, or by a proceeding in intestacy."

The same section requires anyone selling property in that area to tell the buyer that the property is in the service area and what the ordinance requires, whether or not the property is already connected. The village FAQ says the rule covers homes and businesses, and that either the seller or the purchaser must apply as a condition of the sale. Undeveloped parcels don't have to connect until they are built on, and connecting south of Meadowlark, outside the primary area, is optional.

Many buyers expect sewer service to replace the septic tank. In Corrales it doesn't. The village runs a STEP system, which carries liquid effluent from the septic tank but not solids. A connected owner still maintains the tank, pump, filters and electrical supply on the property and still has the tank pumped.

In January 2025, the Corrales Comment reported residential connection charges of $250 to $500, installation costs commonly between $5,000 and $12,000, and monthly residential service of $30, with costs varying by property. Those figures date from early 2025, so treat them as a rough guide and get current quotes. The same article covered the Priestly-Corral sewer extension and suggested that a change in ownership there could also trigger connection. The ordinance limits the sale trigger to the primary Corrales Road service area. For any parcel near a sewer line, confirm its service-area status directly with the Village before writing a hookup into the closing timeline.

The Well Comes With the House, and Its Records Are Public

Without a village water hookup, the well is the home's water supply, and a buyer does the checking on it. The Office of the State Engineer's water rights system publishes well reports, well permits and point-of-diversion records. OSE says using water requires a State Engineer permit, and any new appropriation or change is subject to water availability, non-impairment and possible protest. Matching the well on a property to its permit record belongs on the due diligence list alongside the septic file.

The village's own water records show why these documents matter. On August 18, 2026, the council unanimously adopted Resolution 26-58, the village's 40-year water development plan. The Rio Rancho Observer reported that Corrales had never before submitted a water plan to the State Engineer, and that the vote came during a drought that had forced some farmers to stop irrigating. A water rights audit for the plan found "many compliance issues," including past over-diversions from groundwater wells. The plan relies on a lease with the Town of Bernalillo that offsets 30 acre-feet a year of the village's well diversions through 2030.

Brittany Gaume, a consultant on the village water team, said the village needs about 20 more acre-feet and has to "get ahead of the game" on buying pre-1907 water rights, which she said are getting harder to find and transfer. The village has a $2 million line of credit at 1% for a purchase but won't draw on it until it has a purchase agreement in hand. These rights cover the village's two municipal wells and the surface rights at the Gonzales property, not service to individual homes. For a buyer, the takeaway is practical. The village only recently got its own water paperwork in order, and each private well's paperwork is still the household's job.

How Much You Can Build Is Still Undecided

Density rules are settled. Ordinance 18-008 allows one single-family home per net acre in A-1 and one per two net acres in A-2. Net acreage excludes required dedications, and cluster housing is allowed in A-1 but not A-2. In May 2025, Ordinance 25-01 drew some attention for addressing "municipal lot sizes." It only exempted lots owned or platted by the Village from the one-acre minimum, and it expressly doesn't allow single-family homes on them.

Lot coverage is the open question. The Corrales Comment reported that the comprehensive plan adopted in 2025 recommended cutting allowable lot coverage from 35% to 25% in certain zones. Under current rules, a home larger than 15,000 square feet fits on a one-acre lot. A 25% cap would bring that down to 10,890 square feet. Lot coverage counts all impermeable surfaces, including driveways and slabs, not only the house. That matters for anyone planning a casita, a barn or an arena.

At a January 6, 2026 special meeting, the council didn't vote on the 25% draft. It voted 5 to 1 to keep studying open space options, including floor-area ratios. Public comment that night was split. Some speakers backed the limits as a way to keep the village rural, while others saw them as a restriction on property rights that could lower values. The August 18 minutes listed "Floor Area Ratio Discussion" as TBD, and the September 22 council agenda still did. The 35% rule is still in place, but a buyer paying for expansion potential is relying on a rule the council is actively reconsidering.

A Village-Wide Sewer Is Still Only a Study

A village-wide sewer would remove the septic question for most properties, and the village is studying one. In June 2025, Stantec presented two village-wide options, estimated at $106.7 million and just under $103.1 million. A no-construction alternative stayed in the report. On May 13, 2025, the council approved a resolution for a $2 million NMED design grant. Councilor Stuart Murray voted no, and the grant pays for design, not construction.

The nearest-term project is smaller. A $1,092,000 federal appropriation is slated for a non-residential bypass line along Loma Larga Road, designed by Stantec. As of March 2026, construction was expected later that year. At an April 14, 2026 meeting, council minutes record a discussion of shifting a $16 million collection project toward the bypass, with concern that federal funding might fall short. No vote was taken on that item. No village-wide option has been chosen. For a home outside the Corrales Road area, the septic system named in the evaluation report is the system the buyer should plan to live with.

Corrales Septic and Sewer FAQ

Does connecting to the village sewer mean I no longer pump the tank? No. The STEP system takes only liquid effluent, so the tank stays and still needs regular pumping and maintenance.

Does an inherited property on Corrales Road have to connect at transfer? Ordinance 14-09 exempts transfers by will, transfer on death deed, or intestacy from the sale trigger.

Can an earlier septic evaluation be reused? NMED offers an extension form when a permitted system was evaluated or inspected within the last 180 days and hasn't been used since. The extension adds another 180 days.
