We offer both wet and dry inspections of potable water storage tanks, but which is better for your utility? If your tank has been drained for a repair or other reason we can and have performed dry inspections. However, I would Never ask someone to take a tank out of service just to inspect it. WET or DRY Inspections we can get it done, the wet inspections offer more choices and information at a much lower cost than draining your tank. Our underwater video camera inspection offer state of the art video showing your interior roof & floor with NO DISRUPTION in your water service. We also offer ROV (Remotely operated vehicle) and potable water diver inspections. Visit our web site at http://www.ronperrin.com for more information about our underwater services for potable water.
