When the New York City Department of Environmental Protection (DEP) implemented a STAR® network system to read meters for its nine million customers, it never expected that the benefits of the system would extend beyond simple meter reading.
Those in the water industry know water is essential for life and brings economic value, but the economic role of water is often not as well understood by the general public. This paper reviews the history and development of our transportation, electrical, and energy infrastructure and then presents a plan for our nation’s water to be augmented from where we have it abundantly to where we badly need it.
The 37 million gallon per day William B. Cater Water Treatment plant serves City of Santa Barbara with the majority of its drinking water while also supplying treated water to the districts of Montecito Water, Carpinteria Valley Water, Goleta Water, and La Cumbre Water.
Beyond the existential philosophy implications, the consequences of a pipeline leaking in a forest when no one is around highlight the desirability of leak detection systems in water distribution utilities as a whole. As the following experiences show, leak detection can have its entertaining side. On the other side of the coin, however, the consequences of not monitoring leaks can also trigger a tsunami of costs far beyond the expense of pipeline repair alone.
Since the early 1980s, the 900 MHz frequency band has been widely used for wireless communications in consumer, business, and municipal applications.
Any water utility that has to impose restrictions due to water scarcity appreciates the value of conservation. On the other hand, there are utilities that — knowingly or unknowingly — permit as much as 20 to 40 percent of their treated water to trickle away without collecting a cent for it. If you have experienced either extreme, but are not already using advanced metering infrastructure (AMI), what’s holding you back? Before dismissing AMI as being too costly, too technical, or too difficult to implement, consider the following cost-benefit opportunities.
The benefits of Advanced Metering Infrastructure (AMI) are well known in the water industry, but the public is not as aware of what AMI has to offer. With that in mind, industry experts are looking for ways to educate customers about the value provided by AMI.
Like several of its counterparts in Florida, Pasco County is a name frequently repeated in the news when it comes to growth.
Birmingham Water Works Board (BWWB), Birmingham, Alabama has consistently achieved the rating of the number five water system in the United States for water quality. BWWB’s potable water distribution system (WDS) serves 600,000 people with a daily average use of 100 million gallons (378 million liters) of water, received from nearby lakes and rivers. The system includes 51 water storage tanks, nearly 4,000 miles (6,437 km) of pipe, over 13,000 fire hydrants and over 200,000 service connections.
Diaphragm Operated Automatic Control Valves (ACVs) require reasonably clean water to function effectively and reliably. Having a strainer upstream of the actual ACV is very important, but also having a smaller strainer located at the inlet of the pilot system on the ACV is also well advised.

A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.
The pressures of supplying a growing global population mean that the world’s water supplies need to be managed more closely than ever.
One of the most popular uses for the Telog Hydrant Pressure Recorders (HPRs) is to monitor and analyze customer pressure complaints. The HPR is ideally suited for this application because it is rugged, highly portable, and can give a complete, time stamped picture of the pressure differential between the customer’s water pressure and the water pressure being delivered by the utility.
Pressure reducing valves (PRVs) are used throughout water distribution systems to reduce pipeline pressure to a predetermined set point. This decreases water loss and prevents pipe breaks.
The HR-E LCD encoder has a 9-digit Liquid Crystal Display (LCD) to show consumption, flow and alarm information. The display automatically toggles between 9-digit and 6-digit consumption, rate of flow and meter model.
Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.
Virtually all industries from food and beverage to chemical processing use heat exchangers, condensers,or jacketed vessels. Leakage of the process into the cooling water represents a loss of product and can be a source of fouling or corrosion in the cooling water system.
According to population projections from the U.S. Census Bureau, millennials are expected to become the nation's largest living adult generation by 2019. 37 percent of millennials were homeowners in 2015 and this number continues to rise, making them a significant fraction of a utilities' customer base.
The City of Dallas captured an additional 600,000 gallons of billable water in four months.
Onshore crude oil production has increased in the United States over the past few years. Oil producers, specifically the North Dakota Pipeline Authority and the Bakken Shale field producers are transporting crude oil by rail and train to both the East and West Coast oil refineries. While rail tends to be one of the safer and more efficient ways of transporting crude oil, there is still a risk of a spill. Oil spills are threats to both ground and surface waters, which can ultimately impact drinking water.
This is the time of the year for ghouls, goblins, and things that go bump in the night. Of all the scary things that your water utility might confront on all hallows ‘eve, however, the most chilling might be unforeseen non-revenue water losses from leaks, theft or meter inaccuracies.
In 2017, Orlando residents saw firsthand the negative effects of what could happen when a construction crew caused a major water main break downtown. Not only did the leak become an inconvenience for the city, but it also was expensive to repair.
