The A.W.W.A. (American Water Works Association) recommends inspection and cleaning of potable water reservoirs on a five-year rotation. Many states are now mandating these guidelines for all potable water structures. Cheyenne Diving can assist operators with compliance by inspecting and cleaning these structures on a regular rotation.
In our experience, the amount of bottom material found in potable water structures is primarily influenced by the raw water source. Lake and river sources carry more sediment into the system than water derived from a driven well. Sediment provides an environment for bacteria, protozoa and viruses to thrive, and depletes chlorine reserves. Removing the sediment reduces the need for continual increases of chlorine, and enables you to deliver the cleanest, healthiest water possible to your customers.

We have experience servicing all types of storage tanks: in-ground concrete, blasted rock; on-ground steel or concrete, and elevated steel. We have worked with reservoirs containing Hypalon liners and older structures that may include wood in their design.
Other storage tank services include:
- Removal of all material in the tank, including sediment, sand, and coagulated materials
- Underwater leak detection
- Repairs to exposed re-bar, concrete spalls, or internal plumbing
- Cathodic protection system maintenance and repair
- Inspections of the ventilation screen and hardware
- Inspection of the hatches
- External and internal coating inspections
- Written reports, including both recorded video and still photography
It is far more cost effective than draining the tank
No interruption in service to your customers
No extra cost involved in putting your system back on-line
No extra cost for vacuum trucks to remove the sediment once drained.
Municipality fire protection is not compromised
Smaller systems, with only one storage tank, remain on-
line during cleaning.
Minimal treated water is wasted
