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. Any current or future users of drones should know that entities utilizing drones are now required to comply with new federal laws enacted as part of the FAA Reauthorization Act of 2018. Despite this hurdle, drones provide a great opportunity to help upgrade and improve an otherwise outdated water industry. Overall, drones can be a great tool to help water utilities of the past move more quickly into the future.

The State of California Drinking Water California has long been an epicenter of water issues, but the current megadrought and chronic infrastructure underfunding has brought the crisis to a head. According to a recently published study, California's water systems are beginning to fail across the state. Medium and small-sized public water systems are especially vulnerable. The report claims to be the first comprehensive analysis of how safe water is provided in California. The study sampled 2,779 public water systems and nearly half proved to be at some risk of failing to provide safe drinking water. Roughly one-third of state small water systems sampled in the study were found to potentially contain contaminants like nitrate and arsenic. The greatest takeaway from the findings was that more funding is needed and that investments should prioritize the most at-risk and underserved communities. However, in the short term, bottled water or home filtration systems could be provided to communities that need drinking water immediately, according to the report. Long-term solutions to these problems include enhancing water treatment, consolidating small and underperforming water systems, and recruiting experts that can advise communities on how to improve their systems.
