Potable Water Facility Inspection & Repair
Potable water tank inspections and cleanings are a growing part of our business at Glenn Underwater Services, Inc. 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. Glenn Underwater Services, Inc. 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.
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.
Our video inspections utilize either a diver-mounted camera system or Remotely Operated Vehicle (ROV). Both methods provide top-quality, real-time video feeds, recorded for permanent record. Diver communication with topside personnel is also recorded during inspections of that type. Our video equipment is the best in the industry and puts the client on bottom with the divers, in real-time.
