Trunk sewer under 9400 South mixed-use fill
Deep gravity sewer with tight elevation tolerance — shaft footprints replace a continuous trench that would conflict with shallow Rocky Mountain Power and fiber.

Tunneling / TBM in Sandy, UT
Microtunneling and pipe jacking for Sandy municipal trunk sewers — sealed-face mining when HDD diameter or grade tolerance cannot meet Salt Lake County gravity specs along the Jordan River.
Tunneling / TBM in Sandy, Utah
Tunneling and TBM work in Sandy targets municipal trunk sewers, large outfalls, and owner specs where steerable HDD cannot hold gravity grade or diameter. Shaft spreads localize disruption compared to open trenching a deep urban trunk through utility-congested fill along 9400 South and State Street.
Jordan River and Bell Canyon outfall projects often land here — high groundwater, floodplain review, and settlement limits push engineers toward pipe jacking instead of wide open cuts through Silicon Slopes edge mixed-use blocks and riparian ROW near Dimple Dell.
Residential laterals and short commercial shots stay on HDD or auger bore. Microtunneling in Sandy is a municipal and large-contractor tool — we scope shafts, slurry handling, and Salt Lake County inspection milestones when your plans call for it.

Local Tunneling / TBM Scenarios
Real Salt Lake County angles — not generic statewide copy.
Large outfall toward the Jordan River
Floodplain and bank stability rules favor bored installation over stripping riparian ROW. Shaft design accounts for seasonal high water and I-15 adjacency.
Deep collector near Silicon Slopes edge commercial district
Tech-campus districts combine shallow telecom, chilled water, and gas with deep sanitary collectors. TBM reduces surface disruption across customer-access drives.
UDOT large-span alternative on I-15 corridor
When HDD profile cannot meet large RCP grade on a state crossing, microtunneling may be specified — shafts, spoils export, and MOT are engineered upfront.
How Tunneling / TBM Works in Sandy
Sandy TBM and microtunnel scopes begin with shaft design, geotech, and permit path — City of Sandy, Salt Lake County, UDOT, and Jordan River floodplain where applicable. Laser-guided line and grade drives the mining face; slurry or spoil handling is planned for urban sites with limited laydown near 9400 South. Inspection hold points follow municipal or owner spec before carriers are accepted.
Soil & Geology — Salt Lake County
Sandy bench alluvial fans, lake-bed clay on west grids, and Dimple Dell wash alluvium — cobble increases toward canyon mouths.
Sandy bores hit alluvial fan cobble toward the Wasatch bench, lake-bed clay on west grids, and Dimple Dell wash alluvium on east-side alignments. Uphill lots in Bell Canyon add bedrock risk at depth. Mud weight and ream staging reflect elevation-driven groundwater changes.
Weather & Scheduling
Bench elevation and canyon runoff push Sandy crews to plan mud programs for alluvial fan cobble toward the Wasatch and inversion moisture on valley-floor clay.
Spring canyon runoff raises Dimple Dell wash levels and groundwater on east-side jobs. Summer lightning affects exposed bench pads. Winter inversion moisture softens valley-floor clay — we communicate seasonal windows with your schedule.
811 Locates & Permits in Sandy
Sandy City Public Works, Salt Lake County ROW, UDOT I-15 and I-215 relocations, and Dimple Dell wash floodplain on east-side alignments.
Sandy City Public Works handles street and driveway permits. UDOT controls I-15 and I-215 state corridor bores. Dimple Dell wash floodplain work may need additional review on east-side alignments. HOA communities in Sandy Hills require restoration plans.
Trenchless vs Open-Cut Here
Open trenching a deep trunk through 9400 South corridor or Jordan River ROW destroys more surface infrastructure than shaft-and-drive tunneling. HDD still wins on shallow laterals; TBM applies when diameter, grade, or length exceed practical steerable limits.

How we work
Our Process for Sandy Tunneling / TBM
Scope & Site Walk
You share plans or describe the problem; we confirm alignment, depth, access, and which trenchless method fits Utah soils.
811 Ticket & Marks
Blue Stakes 811 ticket filed; wait period before pits open unless your permit path differs. We pothole where marks conflict.
Profile & Permits
Bore plan, UDOT or city ROW permits, railroad agreements, and crossing engineering when the path leaves private property.
Rig Mobilization
Compact spread for tight Millcreek lots; larger HDD for I-15 or I-80 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 clay or sandstone.
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 sod or hardscape per scope, leave Blue Stakes ticket and locate map in your project file.
FAQ
Tunneling / TBM in Sandy — FAQ
When does Sandy need TBM instead of HDD?
Large-diameter gravity sewer, tight grade tolerance, or owner spec for sealed-face mining. We review your engineer's method note and geotech before quoting.
How long do Sandy microtunnel projects take?
Shaft construction and permitting often exceed mining duration. Jordan River floodplain and I-15 adjacency add calendar weeks — scoped in the estimate.
Is microtunneling common for Sandy residential?
Rare — laterals and short commercial runs stay on HDD. TBM applies to municipal trunk, large outfalls, and engineered deep gravity lines.
What permits apply to TBM in Sandy?
City, Salt Lake County, UDOT, and Jordan River floodplain depending on alignment. Permit path is scoped before shaft design.
Can TBM work in Sandy Wasatch bench clay?
Yes with proper face support and groundwater handling. Geotech and dewatering plans are engineered before mining starts.
