Water Tank Inspections | Benefits of Using ROVs
ROVs are improving water tank inspections by providing efficient and safe alternatives compared to traditional methods.
Efficient and safe alternatives to water tank inspections
Take a drive through any town and you will see the landscape dotted with water towers. This is the culmination of our society using an incredible amount of potable water. It is therefore no surprise that water tank inspectors are in high demand to keep water running efficiently throughout cities and towns.
Traditionally, this meant sending divers into water tanks to inspect community drinking water. Yet this option, apart from being a costly one, can sometimes yield tragic results. Now, thanks to remotely operated vehicles (ROVs), there is an efficient and safe alternative for potable water tank inspections.
The challenges of potable water tank inspections
Potable water tanks are relied upon across a range of industries globally, including on oil and gas platforms and in onshore facilities. Providing water for industrial applications and personal use such as showering and drinking, it is vital that the central supply remains clean and safe. However, managing this can be challenging.
Currently, the most common way to perform inspections is to completely drain a tank and arrange for personnel to perform close-up inspections, which presents a confined space hazard. Tanks are then cleaned or treated if necessary, and then re-filled. This method can take the tank offline for long periods of time.

Top 5 benefits to ROVs and their role in tank inspections
ROVs have the potential to improve the traditional approaches taken to water tank inspections. Our team has encountered the following benefits of using ROVs compared to traditional methods:
- Using an ROV removes the risks associated with confined space entry, which requires permits, planning and paperwork.
- Water tanks do not require discharging or refilling to perform ROV inspections.
- Following an ROV inspection, if remedial works are needed, the footage can be kept and drawn upon, which can help to inform better planning in the future. This can save time and costs in the long-term.
- ROV footage offers the kind of detailed, close-up views necessary to inspect a tank’s internal condition.
- Deep Trekker ROVs have enhanced features and attachments that can gather samples from the inside of a tank and measure wall thickness.
However you choose to conduct your tank inspections, it is vital to ensure that your methods follow best-practice and are established with longevity and the safety of your systems and people as priority.
