1. There is no downtime for water availability
A typical drain-down inspection involves the removal of a water tank while the inspection team enters the bowl. This necessitates the waste of water that would otherwise be consumed by local residents. It also necessitates providing residents with an alternate source of water (continuous pumping or a temporary water source) and disinfecting the tank for AWWA compliance before returning it to service. The water tank can be kept operational with a ROV.
2. They help conserve water
A tank inspection with a dive crew frequently entails removing some of the water for sediment removal or completely removing the water for a drain-down inspection. Water removal is both costly and time-consuming. ROVs can operate inside a tank no matter how much or how little water remains in it.
3. ROVs are cost-effective
As previously stated, there is no need to hire an expensive dive team or remove tank water. When using an ROV instead of a dive team to inspect an elevated water storage tank, savings of up to 50% can be realized. When your consultant owns its own ROV equipment, you can save a lot of money.
4. ROV inspections are more timely
For cities with multiple tanks, using an ROV allows them to inspect up to three tanks in a single day. Using a dive team limits the number of inspections to one per day. Furthermore, while waiting for the dive team takes time, so does waiting for their reports.
5. They allow for peace of mind
A good consulting team that uses an ROV consists of NACE International (NACE) and American Welding Society (AWS) certified personnel who have been trained in providing water tower inspection services.
Bringing it all together
Utility operations include water tank inspections. Regular inspections ensure that the tanks are clean and operating properly, and a consistent inspection schedule allows for easy, ongoing maintenance, which saves money over time. The AWWA suggests inspecting every three to five years. Traditional visual inspections frequently necessitate the use of a separate dive team, which is both expensive and time-consuming. Remotely operated vehicles (ROVs) are assisting in bridging that gap.
How Are ROVs Used For Water Storage Tank Inspections?
ROVs are small, remote-controlled watercraft devices equipped with cameras and sensors that transmit visual, underwater imagery to monitor screens.
Water tank inspection services have used these tiny robotic vehicles to make the task of inspecting potable water storage vessels faster, easier, and more accurate, all without the need to drain the tank.
ROVs allow water tank maintenance services to get a better look inside the tank while it is full to determine its condition without the need for dangerous diving inspections that require permits.
They are now used to perform visual inspections, collect specimen samples from large tanks, and perform other tasks, making it much easier for tank owners to comply with water tank maintenance and routine tank inspections.
ROVs Make Water Tank Maintenance Easier
Prior to the use of ROVs, water tank inspection services were required to drain these massive vessels more frequently in order to properly inspect and maintain their interiors.
ROVs allow for nearly the same accuracy during inspections while not taking tanks offline for days or weeks at a time and sacrificing their contents.
While it may still be necessary to take tanks offline and drain them to perform certain types of water tank maintenance, the decision can be made more easily using an underwater ROV.
ROV inspections are a popular choice for owners of large water storage vessels because these remote-controlled, camera-carrying robotic devices make water tank maintenance and inspections faster, easier, safer, and less expensive.
