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

DEVCO Development and Engineering provides Horizontal Directional Drilling (HDD) in Coolidge and throughout Pinal County for underground utilities, including water, sewer, power, gas, and communications. We use guided drilling rigs to install pipe and conduit under roads, driveways, and sensitive areas without open trenching, helping owners, contractors, and agencies complete work with less surface disruption and shorter shutdowns.

How Horizontal Directional Drilling Works

HDD is a trenchless method. Instead of cutting a long open trench, we drill a controlled path underground, then pull your pipe or conduit back through that bore.

The process usually runs in three main steps:

First, we drill a small “pilot” hole along a planned path using a steerable drill head and locating system. Next, we enlarge that hole with reamers to match your pipe size. Finally, we pull the product pipe or bundle of conduits back through the bore in one continuous operation.

This approach is ideal for Horizontal drilling under pavement in Coolidge—crossing streets, intersections, driveways, or railroad easements—where cutting and replacing pavement would be slow, costly, or disruptive.

Why Owners Choose HDD in Pinal County

Whether you’re extending utilities to a new development, upgrading an industrial site, or tying in rural services, HDD reduces surface impact. Traffic keeps moving. Landscaping stays largely intact. Existing improvements don’t have to be demolished just to get a pipe from Point A to Point B.

Horizontal Directional Drilling (HDD) Coolidge projects are common for utility crossings under city streets, commercial parking lots, irrigation canals, and tight residential corridors where there simply isn’t room for a wide trench.

Typical Underground Utility Uses

We drill for a wide range of underground utility work, including:

• Water and sewer service lines and mains
• Power and telecom conduits to commercial and residential sites
• Gas service and distribution lines
• Crossings beneath paved roads, rail, and hardscape areas
• Conduit banks for future fiber or low-voltage systems

What To Sort Out Before Drilling Starts

A good HDD job starts with good planning. We’ll walk you through:

Utility locates and records. Existing lines must be clearly identified and marked. Any as-builts or private utility sketches you can provide are extremely helpful.

Entry and exit pit locations. Even with HDD, we still need reasonable access areas at both ends. We’ll review space for the drill rig, support truck, and mud management.

Pipe type and length. Diameter, material, and bend limits all affect the bore path. Longer or larger bores may need extra staging space or reaming passes.

Permits and traffic control. Each jurisdiction is different, but we’ll coordinate with you and your design team so requirements are addressed before we mobilize.

Why Experience Matters With HDD

HDD looks simple from the surface, but below ground there’s a lot going on. An inexperienced operator can stray off line, punch up through pavement, or damage existing utilities.

Our team focuses on bore path design, proper drilling fluid selection, and real-time tracking so the line and grade match the plan. We manage drilling mud so it stays in the bore, and we document installations so you have a clear record when the job’s done. As a certified DVBE, SDVOSB, PDBE, SB-Micro, and SB-PW contractor, we understand both technical performance and public project expectations.

Common Questions About HDD

How accurate is HDD?
Modern locating systems let us track the drill head in depth and position along the alignment. For most utility work, we can stay within a tight tolerance band relative to the planned line and grade, assuming realistic design and soil conditions.

Will drilling tear up my pavement or yard?
We usually only need small entry and exit pits. The pavement above the bore stays in place. After installation, we restore disturbed spots as specified—typically compacted backfill, patch paving, or landscape repair.
