As transmission infrastructure expands across the Southwest, more pipelines find themselves sharing right-of-way with high-voltage lines. The result is induced AC voltage and a new set of problems layered on top of the corrosion control work already in place.
Induced AC accelerates corrosion at coating holidays, where bare steel is exposed and current density concentrates. It creates step and touches potential hazards for crews working on valves, test stations, and other appurtenances. And during a fault, the energy that couples into a parallel pipeline can damage coatings, take out instrumentation, and overwhelm CP equipment that wasn't designed to absorb it.
Effective mitigation starts with modeling the interference along the full parallel run characterizing voltage and current behavior under both steady state and fault conditions. From there, the design work begins ribbon anodes, deep anode beds, or gradient control mats sized and placed to drain induced current safely to earth, without disrupting the cathodic protection system already protecting the line.
That balance mitigating AC interference while preserving DC cathodic protection is where the engineering matters most.
The video shows just how much interference there is when walking under power lines.

Forty years. Thousands of miles of Close Interval Surveys across the country's most demanding pipeline systems.
What sets ACCI's CIS work apart is the bench. Our Lead Technicians and Project Managers bring the kind of field instinct you only get from years of permitting tough rights-of-way, troubleshooting on the fly, and finding ways to move crews efficiently without compromising data quality.
We've also built our process around transparency. Field crews transfer data back to the office every evening. By the next morning, it's processed, mapped in Google Earth, and posted to our CIS Daily Portal for client review There is no waiting weeks to see how the survey is going.
The trust we've earned shows up in our client roster: El Paso Natural Gas, Tucson Water, Kinder Morgan, Transwestern, Southwest Gas, Centurion Pipeline, PG&E, Southern California Gas, and many more.
Planning a CIS project? Let's talk.

When a pipeline operator or municipal water utility brings ACCI onto a project, they trust us with infrastructure that can't afford to fail quietly. That trust has to be backed by more than reputation it must be backed by process.
That's the purpose of our in-house Quality Management System. It ensures continuity across every project in Method of Approach, Work Performance, Operator Qualifications, Safety Training, and Regulatory practices, regardless of who's on site or where the work is happening.
Quality Control is the day-to-day discipline: structured checklists covering onboarding, safety training, project management, equipment calibration, and engineering procedures. Nothing left to memory or assumption.
Quality Assurance is the verification layer. Through audits of both unscheduled and client requests we confirm that checklists aren't just being completed but driving the right outcomes. When critical non-conformance does surface, we issue a formal Root Cause Analysis, so the issue is understood, corrected, and prevented recurring.
It's how we give our clients and our own leadership confidence that what we promise is what we deliver.

ACCI Waterworks Division — Protecting Municipal Water Storage Assets Since 2015

Since 2015, Accurate Corrosion Control, Inc. (ACCI) has supported municipalities and water system owners in extending the service life of their steel water storage assets. Our Waterworks Division specializes in the design, installation, and maintenance of internal and external cathodic protection (CP) systems, delivered in full compliance with AMPP/NACE, AWWA, and industry best‑practice standards.

What That Looks Like in Practice

→ Comprehensive CP System Design
Engineering of impressed current and galvanic CP systems for both internal and external reservoir surfaces, designed to meet AWWA D104, and AWWA D106, criteria.

→ Annual Maintenance & Inspection Programs
Full‑service annual CP inspections, testing, and maintenance programs that ensure system reliability, regulatory compliance, and extended coating life.

→ Rectifier Services
Repair, replacement, calibration, and optimization of CP rectifiers to maintain proper system output and protection levels.

→ Remote Monitoring Solutions
Installation and configuration of remote monitoring units for continuous oversight of CP system performance, reducing site visits and improving response time.

→ The ACCI Galvanic CP Controller
A purpose‑built controller for galvanic CP systems in potable water tanks—engineered for simplicity, reliability, and accurate monitoring. Built on AWWA D106, and AMPP RP0196. Supported by certified technicians and active AWWA involvement. Installed nationwide.

Safety isn't a checkbox at ACCI — it's how every project begins.
Before our crews break ground, energize a rectifier, or step onto a customer site, we make sure every person is trained, certified, and prepared for what the job demands.
What that looks like in practice:
— A robust Injury & Illness Prevention Program backed by Computer Based Training through JJ Keller
— OSHA 10 certification for every new hire; most field and engineering staff carry OSHA 30, MSHA, and Competent Person certifications, renewed annually
— Daily Job Safety Analysis (JSA) reports and job-specific Emergency Action Plans (EAP) before any project starts
— Operator Qualifications and pre-job safety overviews on every site
Whether the job is a water utility in Phoenix or a pipeline running through right-of-way in West Texas, the standard doesn't change.

Do you know what's in the soil around your buried infrastructure?

Soil resistivity is one of the most critical factors in cathodic protection design. It's a factor in how much current your system needs, what anodes to use, how to configure them, and ultimately whether your buried infrastructure is protected.

Across the Southwest, soil conditions make this especially challenging. Arizona alone has diverse soils with zones of extremely high resistivity — or surprisingly low resistivity with high chloride pockets — clay and loamy soils that contract with moisture, and sandy desert soils that shift from high to low resistivity between dry season and monsoon season.

All of it creates a challenging environment for the design and performance of cathodic protection.

Corrosion doesn't just live underground.
On electrical transmission lattice towers and poles, some topping 400 feet, many are in remote stretches of Northern California the atmosphere works on the steel from above while soil conditions go to work on the legs below. Both sides matter.
ACCI addresses both.
Above grade, our field technicians certified in 100% tie-off climbing and elevated rescue to perform methodical inspections of the steel to identify atmospheric corrosion and mechanical wear that a ground-level look will never catch.
Below grade, ACCI was selected by an electric transmission operator to pilot an assessment, design, and installation program for cathodic protection on tower legs a scope neither ACCI nor the operator had performed before. We built the process from the ground up: preliminary field data collection, condition assessment, design, and installation.
That pilot is now the operator's accepted standard process for this work moving forward.
The same technical foundation behind every project: an in-house, solutions driven development team, corrosion laboratory R&D team, certified staff for ex*****on, and an employee-owned since 1984.

One survey won't cut it.

Pipeline integrity requires layering multiple assessment techniques to build a complete picture — and that's exactly what External Corrosion Direct Assessment (ECDA) is designed to do.

At ACCI, our ECDA process brings together CIS, ACVG, DCVG, current span, current attenuation, casing testing (including Panhandle), test point surveys, depth of cover, atmospheric testing, and roadway drilling — all performed by AMPP certified, operator qualified professionals.

No single data point tells the whole story. But when combined, that's when you get the clarity to make real integrity decisions.

ACCI has been delivering full-scope corrosion assessment services since 1984. If you need a team that can handle the entire ECDA process under one roof, we're ready.
