Water utilities are tasked with ensuring a sustainable and safe supply in addition to achieving business and service excellence goals. These goals are typically based on criteria that measure operational performance, meeting bond covenants, and customer satisfaction.
Activated sludge has been a cornerstone of wastewater treatment since the early 1900s. Over the years, variations of the activated sludge treatment process have surfaced. These variants were efforts to improve treatment performance or reduce capital or operating costs. A new technology, known as Nereda®, uses aerobic granular sludge to meet all those criteria.
It was reported in Verizon’s 2016 Data Breach Digest that a hacktivist group associated with Syria hacked into an anonymous water utility’s control system and changed the levels of chemicals being used to treat tap water. An unnamed water district, dubbed the Kemuri Water Company (KWC), experienced unexplained patterns of valve and duct movements over at least a period of 60 days.
The journey to “smart” has proven more challenging for wastewater networks than for potable water, but real-world impact is imminent. Learn what potential awaits the industry at monitoring’s latest frontier.
A smart-water expert details the impact of data and analytics on the water sector.
Big Data is often characterized by the large volume of data, the wide variety of data types and the velocity at which the data must be processed. Data can come from many different sources, such as social media use, online purchases, licensed twitter data streams or sensors used in the Internet of Things (IoT).
AWWA's Annual Conference & Exposition (ACE) hits The City of Brotherly Love with a flurry of new technologies.
Cities that champion infrastructure improvements and embrace connectivity are well on their way to attracting today’s citizens and encouraging growth. Here’s a look at the benefits a smart city provides for its residents, workforce, and visitors.
As fresh water supplies dwindle, whether due to drought, contamination, or overuse, desalination becomes more attractive. Desalination plants must ensure proper flow measurement to monitor the resource — so proper installation and operation of these meters is extremely important.
Flow velocity is defined in fluid dynamics as the specific distance (feet, yards, or miles) fluids such as water and wastewater travel in an exact period of time including seconds, minutes, or hours. In managing your water/wastewater, applying this tool can be very useful.
