BAT & Coatings, was contacted by a Northern California Water Company to perform an inspection on a water tank. We contracted Pro-ROV Services, LLC to perform a Remotely Operated Vehicle (ROV) inspection. The inspection was performed on April 10, 2017, using a SeaBotix LBV (Little Benthic Vehicle). ROV and tether disinfection was performed on site, then the ROV was deployed into well through an open-air access point.
During the inspection there is a no-flow situation inside the well, with pumps in the off position
A box inspection was used in order to cover the entire well. This was accomplished by moving down one outer well wall, dropping down 2 feet and then back along the same wall until the bottom of the tank is reached.
Each roof support column or pillar was inspected in the same manner.
The purpose of the inspection is to identify and log the overall condition of the underwater water portion of the interior well, as well as look at the blades of each pump.
