Corrosion, Electrical and Forensic Engineering in Colorado
Dreiym Engineering has an office in Westcliffe, Colorado, and works across the state. Our Colorado work centers on cathodic protection: surveys and design for pipelines and flowlines in the DJ Basin and along the Front Range, underground storage tank testing, municipal gas system programs, and AC interference work where pipelines share corridors with power lines and rail. We also do electrical power studies and design, and forensic investigations of fires and electrical failures.
Our engineers are licensed Professional Engineers with active and past licensure in multiple states, and our designs and reports are PE-stamped where required.

Corrosion Engineering
Colorado’s dry, rocky ground resists the current that cathodic protection runs on, and its resistivity can change sharply over a few hundred feet. We measure it along the route with soil resistivity and corrosivity testing, run CP surveys (close interval, DCVG and ACVG) and interference testing, and design, install and commission systems sized for the driest ground expected.
Electrical Engineering
Facilities along the Front Range use our arc flash studies, short circuit analysis and protection coordination studies, modeled in ETAP and SKM, with arc flash labels printed and installed or shipped to you. We also run grounding system tests and provide electrical design, from load calculations to construction support.
Forensic Engineering
Insurers, law firms and owners call our forensic engineers after Colorado fires and explosions, lightning damage and electrical failures, and after corrosion failures on pipelines and tanks. We inspect the scene as soon as possible and examine evidence at our lab in Coldspring, Texas. Submit a forensic assignment.
About Us
Our Colorado Office in Westcliffe
Dreiym Engineering was founded in 2014, with offices in Westcliffe, Colorado and in Coldspring, Texas, where our engineering lab is. Our cathodic protection team includes Stepan V. Eero, M.S., P.E., a NACE CP Specialist (CP4), and Brian J. Brackensick, M.S., P.E., a NACE CP Technologist who also leads our electrical power studies.
Besides external corrosion, we take on internal corrosion problems, and we design remote monitoring for rectifiers and CP systems on sites that are hard to reach in winter.
How Colorado shapes the work
Two things set Colorado apart: the ground and the corridors.
High-resistivity soil. In the foothills, crews hit decomposed granite, cobble and shallow bedrock. On the plains, DJ Basin gathering lines cross irrigated cropland and dry ground on the same route. Readings can change by a factor of ten between test locations, and frozen ground reads higher still. A design copied from a Gulf Coast job can come up short here, so we measure along the actual route and size the rectifier and groundbed for the driest ground expected. Our article on cathodic protection in high-resistivity Rocky Mountain soils goes into the details.
Shared corridors. As the Front Range grows, pipelines, transmission lines and rail end up in the same narrow corridors. AC induced on a pipeline can create touch voltage hazards and AC corrosion at coating holidays, even while the CP readings look acceptable. See our page on AC interference testing and mitigation in Colorado.
Programs for Colorado owners and operators
- Underground storage tank cathodic protection: the 3-year tests, the 60-day rectifier inspections and repair design.
- Municipal gas cathodic protection: the annual 49 CFR 192.465 survey, rectifier rounds six times a year and repair design for towns that run their own gas systems.
- Pipelines and flowlines: annual surveys, close interval surveys where test station readings fall short, and coating surveys. Our article on cathodic protection compliance for Colorado pipelines and flowlines explains which rules apply to which lines.
- Water and wastewater districts: integrity assessments of aging steel mains and storage tanks.

Frequently asked questions
Do you have an office in Colorado?
Yes, in Westcliffe. Our other office and our engineering lab are in Coldspring, Texas. We work anywhere in Colorado, from the DJ Basin to the Front Range and the southern part of the state.
Why is cathodic protection harder in Colorado soil?
Dry, rocky ground has high resistivity, so an anode needs more voltage to push the same current into it. Galvanic anodes have little driving voltage to spare, so larger or poorly coated structures usually need impressed current. Where better ground lies deeper, a deep anode groundbed often works better than a shallow one. We design for the driest readings expected, not an average.
What do Colorado underground storage tank owners need to test?
A protected tank or piping system has to be tested within 6 months of installation or repair and then at least every 3 years, and impressed current systems need an inspection every 60 days. See our Colorado UST cathodic protection page.
Do you design and install cathodic protection, or only test it?
Both. We design, install and commission galvanic and impressed current systems, and test existing ones. Unless you specify otherwise, we design galvanic systems for a 20-year life and impressed current systems for a 30-year life.
