Wet Utilities:

Wet Utility Contractor in Texas — Sewer, Water & Stormwater

DNT Construction self-performs underground wet utility installation across Texas — sanitary sewer systems, water main distribution, storm drainage networks, and stormwater detention and retention facilities — for commercial, industrial, municipal, and data center projects. All work is performed by DNT's own pipe crews and coordinated with local municipalities, MUDs, and utility districts through the full permitting, inspection, and acceptance process.

Integrating wet utility installation with DNT's mass grading and dry utility scopes under one contractor compresses the underground phase and eliminates the schedule conflicts that arise when separate subs share the same corridor.

Wet Utility Scope We Self-Perform

• Sanitary sewer gravity mains, force mains, and lift stations
• Potable water distribution and transmission mains
• Fire hydrant leads and service laterals
• Storm drain systems — RCP, HDPE, and box culverts
• Inlet and manhole structures
• Stormwater detention and retention pond construction
• Private on-site water loops and fire suppression mains
• SWPPP administration and trench dewatering
  
  

Why Developers and GCs Choose DNT for Wet Utilities

MUD, City, and Water District Experience

DNT has extensive experience working within the Texas MUD structure and with city utility departments for plan approval, pressure testing, bacteriological sampling, TV inspection, and final acceptance. DNT project teams understand the specific requirements of City of Austin Water, San Antonio Water System (SAWS), City of Houston Public Works, and the regional MUD network — and build those requirements into the schedule.

Lift Station and Force Main Capability

DNT installs sanitary sewer lift stations — both precast wet-well and fiberglass packaged stations — along with associated force mains and controls conduit on sites where gravity drainage is not feasible. Pump selection and sizing are determined by the civil engineer; DNT coordinates with the equipment supplier and the accepting utility through installation and startup.

Concurrent Wet and Dry Utility Installation

Because DNT controls both wet and dry utility scopes, trench alignments are coordinated in preconstruction for parallel operations. On a typical 100-acre site, concurrent installation can reduce the underground utility phase by 2 to 4 weeks compared to sequencing separate subcontractors.

SWPPP and Stormwater Compliance

DNT administers a site-specific SWPPP on every project disturbing one or more acres under TCEQ Construction General Permit TXR150000. Trench dewatering, inlet protection, and post-rain inspections are managed statewide by DNT's safety and environmental team.

Frequently Asked Questions

What underground wet utility work does DNT self-perform?

DNT self-performs sanitary sewer gravity mains, force mains, and lift stations; potable water distribution and transmission mains, fire hydrant leads, and service laterals; storm drain systems including reinforced concrete pipe, HDPE, and box culverts; inlet and manhole structures; and stormwater detention and retention pond construction. On large commercial and data center sites, DNT also installs private on-site water and fire suppression loops as part of the civil scope.

Does DNT work with Texas MUDs, water districts, and municipalities for utility acceptance?

Yes. DNT has extensive experience with Texas MUD structure and city utility departments for plan approval, inspection scheduling, pressure testing, bacteriological sampling, TV inspection, and final acceptance. DNT project teams understand the specific submission and inspection requirements of City of Austin Water, SAWS, City of Houston Public Works, and the regional MUD network.

Can DNT install lift stations and force mains for sites that cannot gravity-drain?

Yes. DNT installs sanitary sewer lift stations — both precast wet-well and fiberglass packaged stations — along with associated force mains, check valves, and electrical and controls conduit. Lift station sizing and pump selection are determined by the civil engineer; DNT coordinates with the equipment supplier and the accepting utility's inspection requirements through installation and startup.

What is the typical lead time for water and sewer plan approval in Texas?

City of Austin review runs approximately 6 to 10 weeks. San Antonio Water System (SAWS) typically reviews in 4 to 8 weeks. City of Houston reviews can run 6 to 12 weeks. MUD-served projects depend on the district engineer's review timeline and the MUD board's meeting schedule, which can add 2 to 4 weeks. DNT recommends submitting utility plans concurrent with site plan submittal — not after — to prevent utility approval from becoming the critical path item.

Can DNT coordinate wet and dry utility installation concurrently?

Yes. Because DNT controls both scopes, trench alignments are coordinated in preconstruction to allow parallel operations where pipe separations permit. On a typical 100-acre site, concurrent wet and dry utility installation can reduce the underground utility phase by 2 to 4 weeks compared to separate subcontractor crews working sequentially.
