Trunk sewer under Main Street commercial fill
Deep gravity line with tight tolerance — shafts replace trench through shallow PNM and fiber congestion.

Tunneling / TBM in Los Lunas, NM
Microtunneling for Los Lunas municipal trunks and bosque outfalls — pipe jacking when HDD cannot hold gravity grade in conservancy-adjacent fill.
Tunneling / TBM in Los Lunas, New Mexico
Tunneling and TBM work in Los Lunas targets deep gravity sewer, large storm outfalls, and specs where steerable HDD cannot meet diameter or elevation tolerance along Main Street utility fill. Shaft spreads concentrate impact versus open trenching trunk lines through the village core.
Bosque outfall and conservancy-adjacent flood-control projects often land here — high groundwater and settlement limits push engineers toward pipe jacking instead of wide open cuts through trail systems along the Rio Grande fringe.
Residential laterals and short commercial shots stay on HDD. Microtunneling in Los Lunas is municipal-scale work — we scope shafts, slurry handling, and village inspection milestones when plans call for it.

How Tunneling / TBM Works in Los Lunas
Los Lunas microtunneling starts with shored, dewatered shafts surveyed to village hold points. Steering head mines the face; pipe jacks behind on laser grade. Slurry handling matches bosque groundwater; inspection follows municipal contract milestones.
Soil & Geology — Valencia County
Valencia County bosque fringe carries Rio Grande sand, adobe clay, and caliche hardpan — irrigation ditch proximity and old farmland cobbles change mud programs parcel to parcel.
Los Lunas bores encounter Rio Grande valley sand and adobe clay on bosque-adjacent parcels with caliche hardpan between 2 and 7 feet on mesa-top infill. Old farmland grading can hide cobble lenses and buried irrigation structures that potholing catches before pits are sized. Shallow groundwater along conservancy ditches and the bosque raises buoyancy risk on longer HDPE pulls — we size ream stages accordingly, not with a Permian basin template.
Weather & Scheduling
Middle Rio Grande valley heat, spring wind, and monsoon runoff shape Los Lunas bore schedules — bosque groundwater and conservancy ditch saturation are built into quotes.
Monsoon season from July through September softens bosque-adjacent ROW and can delay entry pits on sandy fill. Spring wind affects cage and fluid handling on exposed I-25 pads. Winter cold snaps slow morning startup but rarely stop work — we communicate when dry conditions matter for caliche-heavy pits rather than risk frac-outs toward conservancy ditches.
811 Locates & Permits in Los Lunas
Village of Los Lunas Community Development, Valencia County ROW, NMDOT District 3 on I-25 and NM-314, Middle Rio Grande Conservancy District easements, and PNM agreements apply on many alignments.
Village of Los Lunas Community Development governs street cuts, driveway removals, and drainage work along municipal ROW. Valencia County rules apply on unincorporated parcels toward the agricultural fringe. NMDOT District 3 controls I-25, NM-314, and state highway bores — MOT plans are common on Main Street frontage. Middle Rio Grande Conservancy District easements along irrigation laterals add coordination beyond standard 811. PNM easement agreements govern electric-adjacent paths.
Trenchless vs Open-Cut Here
Open trunk trench through Main Street retail strips hits storefront access and shallow utilities. Shafts localize disruption. HDD rarely replaces microtunneling on large gravity sewer with strict municipal tolerance.

How we work
Our Process for Los Lunas Tunneling / TBM
Scope & Site Walk
You share plans or describe the problem; we confirm alignment, depth, access, and which trenchless method fits New Mexico soils.
811 Ticket & Marks
New Mexico 811 ticket filed; two business days minimum before pits open unless your permit path differs. We pothole where marks conflict.
Profile & Permits
Bore plan, NMDOT or city ROW permits, railroad agreements, and crossing engineering when the path leaves private property.
Rig Mobilization
Compact spread for tight Santa Fe lots; larger HDD for I-25 or I-40 relocations — matched to length and diameter.
Pilot & Ream
Steered pilot on design line, ream passes sized for your pipe or casing, fluid program tuned for caliche or adobe clay.
Pullback & Install
HDPE fusion, steel casing, or multi-duct bundle pulled with tension and bend-radius monitoring.
Test & As-Built
Pressure test, mandrel, or survey records for owners, inspectors, and operators as spec requires.
Restore & Closeout
Compact pits, replace gravel or hardscape per scope, leave 811 ticket and locate map in your project file.
FAQ
Tunneling / TBM in Los Lunas — FAQ
When does Los Lunas work need microtunneling instead of HDD?
Large gravity sewer, tight grade, or sealed-face spec in plans — method stays with engineer approval.
Are TBM shafts disruptive in Los Lunas neighborhoods?
Shafts are smaller than a full trunk trench but still need traffic control and gravel restoration.
Who handles municipal inspection on tunnel jobs?
We coordinate with your engineer for shaft, mining, and reception hold points per contract.
Is microtunneling economical for residential Los Lunas jobs?
Rarely — short laterals use HDD. Trunk scale justifies shaft spreads.
