Monitoring disinfectant residuals (i.e. Free and Total Chlorine and/or Chloramine concentration) is one of the most essential practices in drinking water management programs. This ensures that sufficient protection is maintained at all points in the distribution system. The absence of a disinfectant residual means that suppression of microbiological growth is much more difficult and the rate of regrowth can be significantly accelerated. However, does maintaining an adequate disinfectant residual provide enough protection?
Crews in Nashville and Davidson County, Tennessee, at times have worked around the clock – 24 hours a day, seven days a week – to complete Metro Water Services’ Cumberland City Low Transmission Water Main project. There is good reason for this full-throttle approach. It minimizes traffic issues and allows for more scheduling flexibility.
U.S. EPA funding and water programs took a major hit in a budget proposal from President Trump released this week.
While the majority of household consumers believe that they deserve the full attention of a water system, from a revenue perspective this does not bear out. Though the average home faucet is undoubtedly valued by its drinking water provider, the reality is that the vast majority of drinking water revenue comes from heavy-use commercial and industrial operations.
According to the U.S. EPA, $97 billion will be needed over the next two decades to control water loss, comprising 29 percent of the needed upgrade costs in the space overall. The agency estimates that average water loss for a system is 16 percent, with 75 percent of that being recoverable.
There is one device that truly encompasses the relationship between drinking water utilities and the consumers who benefit from their services. The water meter represents both the practical aspect of the dynamic (that is, the calculation of how much drinking water reaches a ratepayer and, therefore, what rate they pay), as well as the shared connection that each household has with its provider.
Drinking water utilities have a lot on their plates. Aside from the inherent technical difficulty of providing a vital service, they have to maintain positive customer relations, contend with increasingly strained budgets, and run operations with as little stress to employees as possible.

This video provides a close up view of the Huber SOLSTICE solar dryer technology in operation. Turning is very important in a solar sludge dryer as new surface area needs to be exposed to the dryer air. Check out how the turning mechanism helps to break up the sludge into smaller granules.
The design of a utility’s ozone disinfection system often includes a method to minimize the production of regulated oxidation by-products that may form when ozone contacts the water. In regions where water contains a significant concentration of bromide ion (Br¯ ), ozone disinfection systems often minimize bromate (BrO3¯ ) formation by modifying the water chemistry through the addition of chloramines, acid, or other chemical additives.

Researchers say they have found a way to filter water using 1,000 times less energy than conventional processes. The trick is to get rid of membranes.
When a piece of process equipment needs to be replaced, it is tempting to go with a straight replacement in kind – same manufacturer, same model, just the latest version of “the same”. But often, full consideration of other options opens new possibilities for your treatment plant. That was certainly the case for Plainfield, Indiana.
Combined with the installation of the new filter media and wash troughs, this particular type of underdrain and media retainer brought the water treatment plant’s operations up to speed.

In spite of the recent abundance of water, many of California’s aquifers continue to balance on the edge of water scarcity. Decades of overpumping have reduced the amount of ground water available to supplement surface water resources diminished by drought.
