Horizontal Directional Drilling (HDD) in South Tucson by DEVCO Development and Engineering

DEVCO Development and Engineering provides Horizontal Directional Drilling (HDD) in South Tucson and across Pima County for utility owners, contractors, and public agencies. We install underground power, telecom, water, gas, and conduit with minimal surface disruption, using guided drilling equipment and vacuum systems to place new lines on grade while avoiding existing utilities.

What Horizontal Directional Drilling Actually Does

Horizontal Directional Drilling is a trenchless method used to install underground utilities without cutting long open trenches. We drill a guided pilot hole from a launch pit, steer beneath obstacles, then enlarge the bore and pull back pipe, conduit, or cable.

For busy South Tucson corridors, tight neighborhoods, and sensitive areas near businesses, HDD lets us cross under streets, driveways, washes, and landscaping while keeping the surface mostly intact.

Typical HDD Utility Projects in Pima County

We handle both small and large Horizontal Directional Drilling (HDD) South Tucson projects. Common situations include:

• Street and intersection crossings for new water, sewer, and fire service lines
• Directional drilling for utilities South Tucson telecom and fiber backbone routes
• Electric duct banks under roads, railroad easements, and parking lots
• Service replacements where trenching would damage improvements or driveways
• Conduit banks for future utility expansion on commercial sites

How the HDD Process Works

Every job starts with utility locating, plans review, and site walk-through. We want to know where existing lines are, where you need to start and end, and what surface improvements must be protected.

From there, we typically follow three main steps:

1. Pilot bore: Using a steerable drill head and locating system, we guide the bore along the planned path and depth, checking frequently for clearance from existing utilities.

2. Reaming: Once the pilot hole is confirmed, we enlarge it in stages with reamers matched to soil conditions and final pipe size.

3. Product pullback: Finally, we pull the pipe or conduit back through the bore in one controlled operation, monitoring loads and drilling fluid returns.

Why Owners Choose HDD Instead of Trenching

Open cutting a road or yard is sometimes fine. Other times, it’s messy, slow, and disruptive. HDD is usually chosen to:

Reduce surface damage. Less saw-cut, fewer patches, less impact to traffic and neighbors.

Work in tight spaces. We can start and end in small pits instead of long trenches winding around obstacles.

Maintain operations. Businesses often stay open while we drill underneath access drives and parking areas.

What to Know Before You Start an HDD Project

You don’t have to be an HDD expert, but a few things help move the job along:

Have at least a rough alignment, preferred depths, and utility size in mind. Share any as-builts you have. If it’s a public right-of-way, plan time for permits and traffic control review. When we talk, we’ll help sort out what’s realistic for your route and budget.

Experienced vs. Inexperienced HDD Contractors

The difference usually shows up in planning and clean-up. An experienced HDD crew will:

Ask questions about existing utilities, elevations, and future expansion. Match drilling fluids and tooling to local soils. Keep bores within planned tolerances. And manage spoils and drilling fluid so the site isn’t a mess at the end of the day.

As a DVBE, SDVOSB, PDBE, SB-Micro, and SB-PW contractor, we’re used to working on both private and public utility projects that demand documentation, safety, and consistent procedures.

Common HDD Questions

Is HDD right for my project?
If you’re crossing a paved street, busy driveway, landscaped area, or any place where trenching would be costly or disruptive, HDD is usually worth evaluating. For straight, open dirt with no improvements, trenching may still be more economical.

How much does Horizontal Directional Drilling cost?
Pricing depends on length, diameter, soil conditions, depth, and site access. For a deeper dive into the factors that drive cost, you can review this guide on the cost of Horizontal Directional Drilling (HDD).
