Inspection, maintenance, and repair: three phases of one ongoing relationship between water infrastructure and the divers who keep it operational. Each phase informs the next. A thorough inspection catches the issues that maintenance can address before they become repairs. Documented maintenance gives the next inspection a baseline to compare against.

Midco's IMR program supports utility owners, municipal water authorities, industrial facility managers, and engineering firms managing long-lived inland water assets.

What an IMR program looks like in practice:

🔹 Annual underwater inspections with HD video documentation
🔹 Routine cleaning and minor maintenance during the inspection visit
🔹 Repair work scoped from inspection findings and quoted from documented evidence
🔹 Compliance-ready reports for regulators and internal audits
🔹 A baseline that improves every year as the historical record builds

The cost of a planned IMR cycle is almost always lower than the cost of an emergency response after the same issue has been left unaddressed for too long.

Over 23 years of inland IMR experience, with ANSI AWWA and OSHA certified ADCI-rated divers on every project.

Today is Flag Day.

The flag flies at the Midco offices, at our project sites, and on the work trucks of crews traveling the country.

To everyone who has served, who serves, and who carries the values the flag represents into their everyday work, we appreciate you.

To effectively support a field-driven business, you have to understand the reality of the work. This week, members of our office and HR staff stepped out from behind their desks to experience a core part of our field operations firsthand.

The goal wasn't just to observe, but to actively participate in the foundational safety and physical requirements our field crews manage daily.

Fall Protection Certification: The office team underwent standard fall protection training, learning the precise safety protocols, equipment inspections, and compliance measures required on-site.

The Climb: Fully outfitted in harnesses and safety gear, the team put the training into practice by climbing an on-site tank to experience the environment our technicians and divers work in every day.

When administrative and administrative teams truly understand the mechanics of core operations, it changes how we recruit, how we manage risk, and how we support our people. Experiencing the physical demands and strict safety parameters of the field ensures our support staff is fully aligned with our operational reality.

A big thank you to our field crew for guiding the training and keeping compliance front and center.

Steel and infrastructure underwater can be repaired two ways. Pull the asset out of service, dewater it, fix it on the surface, and put it back. Or send a certified crew down to do the work while it stays online.

Midco handles in-service repair where downtime would cost more than the repair itself. For dam gates and spillway structures, intake screens and trash racks, sheet piling and bulkhead, pipeline supports and submerged industrial steel, certified underwater welding is the right tool. The work happens in place, with HD video documentation and welder qualifications matched to the metal being repaired.

Potable water tanks work differently. ANSI AWWA standards prohibit welding inside drinking water tanks because of contamination risk to the water supply. For tank work, our in-service capability covers cleaning, coating assessment, sediment removal, and inspection. Every step is credentialed for potable water, and the tank stays full while we work.

Over two decades of inland underwater repair on live systems under ANSI AWWA and OSHA standards.

Some underwater inspections benefit from a remotely operated vehicle. ROVs reach spaces too tight for a diver, maintain visibility in heavily contaminated water, and document infrastructure in environments where prolonged diver exposure is not the safest choice.

Midco operates ROV systems alongside our commercial diving teams. The right tool for the job depends on the conditions, the access points, and what the inspection actually needs to capture. Long pipeline interiors with limited diver access, narrow intake structures with confined entry, confined-space tank interiors, contaminated industrial waters, and pre-dive surveys that scope the work before crews enter all play to the ROV's strengths.

Some inspections require the tactile assessment and decision-making that only a trained diver can deliver. We make the call based on what the project actually needs, not what is easiest to deploy.

ANSI AWWA and OSHA certified across every inspection. ADCI-rated commercial divers and ROV-trained operators on every team.

Summer is construction season for water infrastructure. New intake structures get built, pipeline expansions tie into existing systems, bridge piers get reinforced, sheet piling goes in, and pump stations build out new wet wells.

Midco's underwater construction crews support marine construction projects across the country, working alongside general contractors, engineering firms, and owner's representatives to keep the dive component on schedule and aligned with the broader project. That support covers below-water rigging and lift coordination plus structural inspections during construction phases.

Construction schedules don't have room for surprises. Daily dive logs and HD video records make handoffs cleaner and keep the engineering team informed as the work progresses.

Over 23 years of inland marine construction support, with ANSI AWWA and OSHA certified ADCI commercial divers on every project.

Picture a Friday afternoon at a water treatment facility. The intake screen seizes up and flow drops. By 4:47 PM the control room is calling vendors, trying to find a crew that can dive tomorrow morning.

This is the call Midco's 24/7/365 dispatch is built for. We answer the phone outside of business hours, on weekends, on holidays, in winter, in summer. Our crews mobilize when other contractors have locked the office for the night.

Our dispatch line is answered by real people, not an answering service. ADCI-rated commercial divers are ready to mobilize on short notice with a safe-assessment-first, documented-response-second, repair-plan-third approach. HD video documentation starts on the first dive, and our team coordinates with your engineering and operations staff throughout the response.

Inland water infrastructure does not break on a 9-to-5 schedule. Our team is built for that reality, with ANSI AWWA and OSHA certifications behind over 23 years of inland emergency response.

Midco's main office sits in Rapid City, South Dakota, with a second location in Peoria, Arizona. Beyond those two physical offices, we maintain 13 regional contact numbers across the country.

That network exists for a reason. Inland water infrastructure failures don't respect geography. A municipal water tank inspection in the Southeast, a dam gate repair in the Mountain West, and an intake structure dredging job on the West Coast can all be in the same week's schedule.

Our regional presence reaches Chicago, Omaha, Minneapolis, Louisville, Memphis, and Columbia through the Midwest and South; Tulsa, Loveland, Billings, and Salt Lake City across the Plains and Mountain West; and San Francisco, Phoenix, and Rapid City through the West and Northern Plains. The same crew of certified, ADCI-rated divers travels to where the work is, and the same ANSI AWWA and OSHA standards apply on every project.

Commercial diving is local in the sense that the work happens on your site, and national in the sense that the team showing up is the same group of trained professionals every time.

You probably did not think about a commercial diver when you flipped on a light switch this morning.

More than 20 percent of the world's electricity comes from hydropower, and commercial divers are essential to the design, construction, and maintenance of dams and hydroelectric facilities. Drove across a bridge on your commute? Commercial divers helped inspect and maintain the piers holding it up. Filled a glass from the tap? Commercial divers helped keep the municipal system that delivered that water clean and operational.

The work our divers do runs beneath the surface of everyday life. Most people never see it. Most people do not need to. But when infrastructure fails, when emergencies hit, when compliance deadlines approach, commercial diving becomes visible very quickly.

Midco Diving and Marine Services exists because communities depend on underwater infrastructure every day. Our job is to keep that infrastructure working so yours does not have to.
