The most expensive mistake on a small industrial site is a pipe or conduit in the wrong place. A water main laid a foot too shallow, a sewer that misses the slab edge, or a conduit stub that falls under a column footing will cost far more to repair than it ever cost to install. We install utilities as one coordinated package, laid out on a single drawing and sequenced so each line goes in once, in the right order, before the slab.
Our package typically includes domestic water, fire service, sanitary sewer, storm drain, natural gas where available, electrical and communications duct, and the connections to the utility mains or poles. We talk to the water, sewer, gas and power providers early, since each has its own standards, inspectors and lead times.
The result is a site where every line is where the drawings say it is, tested and recorded, and where the building crew can start work without wondering what is below them.
We also record every line with GPS or survey coordinates so that a future addition, a new tenant or a repair crew can find them quickly. For owners with more than one building on a parcel, that record often saves a day of locating work on every later project.
One drawing, one sequence
We begin with a combined utility plan that overlays every line on the same grid, with elevations and crossing details. Conflicts are resolved on paper: a gravity sewer takes priority, water stays above or beside as separation rules require, and electrical duct keeps its required spacing. Then we mark the field with the layout and verify with the surveyor.
Installation follows depth. Deepest lines go in first, then shallower ones, and the trenches are backfilled and compacted in layers as we go. We test sewer lines with air or deflection tests and water lines with pressure and disinfection tests, and we record results for the inspector.
What goes in the trench
Water service includes the tap, the meter or vault if the utility requires one, backflow prevention and the line to the building. Fire service is separate and sized by the fire protection engineer. Sanitary sewer runs from the building cleanout to the main, with manholes at the spacing the code requires, and grease or sand interceptors if your process needs them.
Electrical and communications work consists of conduit, pull boxes, pads for transformers and meters, and trenches coordinated with the utility. We lay out the electrical duct bank and underground on the same plan, and the fire water loop and hydrant systems are tied into the same package when the site needs them.
Utilities where growth is happening
Growth in the Santa Fe area is steady and planned. As of a 2023 report, about 1,400 houses had been built in Rancho Viejo, with 8,000 to 10,000 projected over the next 50 years, and the Community College District plan covers about 17,000 acres south of the city. New utility lines in those areas must fit master plans that were drawn long ago, and industrial users often connect to systems that were sized for housing.
Further out, sites may be on wells and septic systems, or at the end of long power lines. We help you decide whether to extend a main, drill a well, install a tank or pursue a different parcel. Those choices can outweigh almost everything else in the budget.
Industrial users also need to ask whether a utility has reserve capacity. Water pressure on a main may drop in late afternoon in summer, power may be single-phase where three-phase is needed, and a gas main may be too small for a new boiler. We ask each utility for a written statement of available capacity before design is far along, which prevents unpleasant surprises when the load letters arrive.
The utility timeline
The utility side moves slowly. Will-serve letters, plan review, tap fees, meter orders, transformer lead times and inspection scheduling each take weeks. We start the utility requests as soon as the site is selected, and we put each of them on the project calendar.
The state has also moved its plumbing and mechanical codes. The 2024 New Mexico Plumbing Code is listed as effective August 1, 2026, with permits issued under either the 2021 or 2024 edition until January 1, 2027. We check which edition applies to your underground plumbing and design to the newer one if your permit could cross that line.
Electrical work follows the 2020 New Mexico Electrical Code, which adopts the 2020 National Electrical Code as amended, so conduit sizes, burial depths and marking all follow that edition. We note both codes on the utility plan so inspectors and trades read from the same page.
What we coordinate closely
We coordinate trenching, bedding, pipe laying, structure setting, compaction and testing with trade partners, and bring in licensed trades for gas, high-voltage and utility-owned work. Briefing the crews in the trench on the plan reduces rework.
We also arrange survey checks to verify line and grade at each stage. Every line is photographed before it is covered and as-built dimensions are recorded for the closeout file.
When the site is in a location where trench work stirs up dust or runs near homes, we keep the open length short, backfill the same day when we can, and plate trenches that cross a drive. Neighbors should be able to get to their driveways every evening, and we plan the work so they can.
Connected work
Utilities connect to stormwater detention and drainage and to ground-up industrial construction. For an advanced manufacturer or a pharmaceutical and life sciences supplier, process utilities such as compressed air, process water or specialty gas add their own routes, and we plan them from the beginning.
If your parcel is in a suburb like Rancho Viejo, the county and the homeowners' covenants may have additional requirements, and we check them before design.
Share the utility questions you have
Send the parcel and your expected loads. We will map where each utility is, what it will take to connect and what each option does to the schedule.
Common Questions
How early should we contact the utilities?
As early as possible. Requests for capacity, service points and fees take time, and some providers need to study the load before answering. We start those conversations during preconstruction.
Who pays for a main extension?
It depends on the provider's policy and the distance. The cost may fall to the owner, with some refund or credit arrangements. We help you estimate the cost before you buy land.
Can we use a well and septic system?
In some rural areas, yes, subject to state and county rules and soil conditions. Industrial processes that use a lot of water or produce waste often need more than a conventional system. We review the options with your engineer.
How do you test the lines?
Water lines are pressure tested and disinfected, sewer lines are air or deflection tested and inspected, and electrical conduit is proved with a mandrel. Results are recorded and signed by inspectors where required.
What if we find an unmarked line?
We stop digging, mark it and call the owner if known. We then work out a plan with the designer and the utility. Locating before digging, with hand digging near known lines, reduces the chance of this happening.
