Potable Water Services


Potable Water Services

Midco has an extensive array of the most specialized equipment for cleaning, inspecting, and repairing potable water tanks. But we don’t just have better tools, we have a better team. It’s that dedicated crew of divers behind the equipment that enables us to provide such a broad range of underwater services for complete potable water storage tank system maintenance. Just another reason why Midco is still the nationwide leader in potable water services year after year.

Our Equipment

Whether it's an on-grade, below grade, clearwell, pedestal, standpipe, or tower, Midco’s cleaning equipment, used solely in potable water storage systems, will remove sand, sediment, flocculated material, lime, and silt from your storage system. All work can be performed while your system is full and operating in a normal manner, eliminating downtime and loss of storage capacity. Of course, all of Midco’s associated in-tank equipment is fully disinfected according to the most recent ANSI/AWWA Standards.

Our Divers

Certifications are just the beginning. When it comes to standards and compliance for public health and safety, a dive team with a wealth of experience that can mobilize promptly and respond appropriately in emergency situations is fundamental. Our reputation allows us to attract the best of the best, and our potable divers are prepared to handle the most critical and challenging potable water projects. Every member of our dive teams are committed to rigorous health and safety codes.

Midco has been providing potable water services and support for nearly twenty years, and that experience is just another one of the reasons we continue to be the leading potable water service provider in the nation. Regardless of the type of tank, or the issue, your first call should be Midco.
