Trunk sewer under 12300 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 Draper, UT
Microtunneling and pipe jacking for Draper municipal trunk sewers — sealed-face mining when HDD diameter or grade tolerance cannot meet Draper City gravity specs along Corner Canyon wash corridors.
Tunneling / TBM in Draper, Utah
Tunneling and TBM work in Draper 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 12300 South and SunCrest.
Corner Canyon wash and Point of the Mountain outfall projects often land here — high groundwater, wash review, and settlement limits push engineers toward pipe jacking instead of wide open cuts through mixed-use blocks and foothill ROW near Traverse Ridge.
Residential laterals and short commercial shots stay on HDD or auger bore. Microtunneling in Draper 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 Corner Canyon wash
Wash stability rules favor bored installation over stripping foothill ROW. Shaft design accounts for seasonal flows and I-15 adjacency.
Deep collector near SunCrest commercial
Hillside 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 Point of the Mountain
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 Draper
Draper TBM and microtunnel scopes begin with shaft design, geotech, and permit path — Draper City, Salt Lake County, UDOT, and Corner Canyon wash review where applicable. Laser-guided line and grade drives the mining face; slurry or spoil handling is planned for urban sites with limited laydown near 12300 South. Inspection hold points follow municipal or owner spec before carriers are accepted.
Soil & Geology — Salt Lake County
Draper bench alluvial fans, Corner Canyon wash cobble, and lake-bed clay on west grids — bedrock risk on SunCrest and Traverse Ridge uphill shots.
Draper bores hit alluvial fan cobble on bench lots, Corner Canyon wash alluvium on east alignments, and lake-bed clay on west grids. SunCrest and Traverse Ridge uphill shots add bedrock risk at depth. Point of the Mountain wind does not change soil but affects exposed pad operations.
Weather & Scheduling
Point of the Mountain wind and bench snow push Draper crews to plan mud programs for alluvial fan cobble and wind-exposed pad holds on SunCrest and Corner Canyon lots.
Point of the Mountain wind affects exposed rig staging year-round. Spring canyon runoff raises Corner Canyon wash levels. Winter bench snow affects uphill pit access on SunCrest lots — we plan seasonal windows with HOA restoration schedules.
811 Locates & Permits in Draper
Draper City Public Works, Salt Lake County ROW, UDOT I-15 Point of the Mountain relocations, and Corner Canyon wash floodplain on east-side paths.
Draper City Public Works handles street and ROW permits. UDOT controls I-15 Point of the Mountain state corridor bores. Corner Canyon wash floodplain work may need additional review on east-side alignments. Uphill HOA communities require detailed restoration plans.
Trenchless vs Open-Cut Here
Open trenching a deep trunk through 12300 South corridor or Corner Canyon 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 Draper 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 Draper — FAQ
When does Draper 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 Draper microtunnel projects take?
Shaft construction and permitting often exceed mining duration. Corner Canyon wash and I-15 adjacency add calendar weeks — scoped in the estimate.
Is microtunneling common for Draper 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 Draper?
Draper City, Salt Lake County, UDOT, and wash review depending on alignment. Permit path is scoped before shaft design.
Can TBM work in Draper sandstone bench geology?
Yes with proper face support and groundwater handling. Geotech and dewatering plans are engineered before mining starts.
