The Benefits of Drones in the Water Industry

Unmanned aircraft systems (UAS), also known as drones, have slowly made their way into various parts of society, including the water sector. They offer a more accessible and affordable way for water utility managers to survey their systems. They also offer plant managers the ability to collect detailed information about the status of their utility through aerial photos and videos. 

The greatest benefits of drones are that they are highly efficient while still being relatively inexpensive. Drones can be used to collect data ranging from updating processes to designing additions, as well as building changes, maintenance, and demolition. 

Some water companies in France are even using drones to inspect sewer operations. They are also being used in New Zealand as part of a water quality monitoring project. Drones are being used in Ireland to survey problems before they arise and catch unlawful dumping that would eventually become issues for wastewater treatment workers to handle. Drones have proven to be especially helpful in the wastewater industry by increasing worker safety, reducing energy consumption, streamlining planning, improving insight and education, and efficiently collecting samples.

It’s a bird, it’s a plane, it’s a DRONE!

So you are thinking it is about time to inspect the outside of your water tanks and above ground assets. According to the Illinois EPA, a water storage tank should be inspected at least every 5 years, so it just may be that time again.

You are probably familiar with the traditional tools for condition inspections such as ladders, scaffolding, harnesses, cherry pickers, helicopters, ROVs, divers and cameras. But these days, you can add another tool to your toolbox: unmanned aerial vehicles (UAVs), or more simply, drones. Drones can offer a safer and possibly more cost-effective method of visualizing the condition of a utility’s facilities. Certainly, these “eyes in the sky” can take a visual inspection to an entirely new level – literally.   

There are clear benefits to using drone technology. According to this Wall Street Journal article, researchers believe the use of drones could cut utility costs and improve worker safety, both for routine inspections and for surveying damage after disasters. Plus, set up and operating costs can be less expensive – initial drone systems can be had for as little as $6,000. Drones can also be used to supplement your GIS program for asset management and to map assets in remote and rural locations.

Yet there are some drawbacks as well. Depending on state and local ordinances and laws, there may be height and line of sight regulations as well as special training/licensing requirements for operators.

There will be a technical session on using drones at the 2017 APWA Public Works Institute in California in September. And the NCAWWA is offering a session at their 2017 Institute, also in September. Can’t wait until September? The Operator Training Committee of Ohio is offering a training in a few short weeks.

NJ Water Association offers a drone service for asset management purposes, emergency response planning, tank inspections and more. Their drone and operator are both registered with FAA to maintain compliance with FAA Part 107 requirements.
