Trunk sewer under State Street 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 Murray, UT
Microtunneling and pipe jacking for Murray municipal trunk sewers — sealed-face mining when HDD diameter or grade tolerance cannot meet Murray City utilities gravity specs along State Street.
Tunneling / TBM in Murray, Utah
Tunneling and TBM work in Murray 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 State Street and the Fashion Place district.
Jordan River fringe and Little Cottonwood Creek outfall projects often land here — high groundwater, floodplain review, and settlement limits push engineers toward pipe jacking instead of wide open cuts through mixed-use blocks and riparian ROW near the I-15/I-215 interchange.
Residential laterals and short commercial shots stay on HDD or auger bore. Microtunneling in Murray 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 Fashion Place district
Commercial 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/I-215 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 Murray
Murray TBM and microtunnel scopes begin with shaft design, geotech, and permit path — Murray City, 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 State Street. Inspection hold points follow municipal or owner spec before carriers are accepted.
Soil & Geology — Salt Lake County
Central Salt Lake Valley lake-bed clay, Millcreek tributary alluvium, and bench fill on east-side redevelopments.
Murray bores hit lake-bed clay on most residential grids and Millcreek tributary alluvium on east-side alignments. Fashion Place corridor fill over native clay adds compaction variables. Spring runoff raises groundwater near tributary paths.
Weather & Scheduling
Central valley inversion and bench runoff push Murray crews to plan mud programs for lake-bed clay and spring groundwater rise near Wheeler Farm and Millcreek tributaries.
Winter inversion moisture softens central valley clay. Spring Millcreek tributary runoff raises east-side groundwater. Summer heat on Fashion Place pads affects crew safety — we plan seasonal windows with tenant schedules.
811 Locates & Permits in Murray
Murray City Public Works, Salt Lake County ROW, UDOT I-15 and I-215 relocations, and Millcreek tributary drainage on east-side alignments.
Murray City Public Works handles street and ROW permits inside city limits. UDOT controls I-15 and I-215 state corridor bores. Millcreek tributary drainage awareness may add review on east-side alignments.
Trenchless vs Open-Cut Here
Open trenching a deep trunk through State Street 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 Murray 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 Murray — FAQ
When does Murray 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 Murray microtunnel projects take?
Shaft construction and permitting often exceed mining duration. Jordan River floodplain and I-15/I-215 adjacency add calendar weeks — scoped in the estimate.
Is microtunneling common for Murray 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 Murray?
Murray City, Salt Lake County, UDOT, and Jordan River floodplain depending on alignment. Permit path is scoped before shaft design.
Can TBM work in Murray lake-bed clay?
Yes with proper face support and groundwater handling. Geotech and dewatering plans are engineered before mining starts.
