Just as different water utilities use different processes for turning raw source water into potable drinking water, so too do they take different routes to account for, and bill for, their output. Here is an overview of a cellular-based approach to collecting and leveraging data from water distribution operations that can achieve the greatest business advantage.
For decades, wastewater management has been a growing problem for the Wider Caribbean Region (WCR), a problem that regional governments have long understood as a threat to the economy, the environment, and to public health. In the Caribbean, most wastewater from cities, industry, and agriculture pours directly into surface water or into the sea completely untreated, degrading residents’ quality of life, as well as the region’s biodiversity, pristine blue waters, and reefs, which are the lifeblood of the vital tourism industry.
Among utilities concerned about resilience and response in natural disasters or other emergencies, precise asset inventory and mapping are high priorities. In truth, there is value in having the same information for everyday purposes as well. For anyone who has ever had a problem locating or tracking key water or wastewater system assets, here are several good reasons and ways to avoid a last-minute scramble.
Wastewater service charges vary considerably across EPA regions and States. That’s one of the key findings from the National Association of Clean Water Agencies’ (NACWA) Cost of Clean Water Index. If you live in Montana, Wyoming or the Dakotas (EPA Region 8), your average service charge of $261 a year is considerably less than the $884 your fellow Americans up in New England (EPA Region 1) are paying. As you can imagine, much of the difference is to do with population size and geography.
The nexus of operations and asset management is coming as the water industry continues its digital transformation. Ongoing asset performance management informed by near-real-time data empowers a streamlined view of which assets are nearing the end of their useful lives, and which are operating at optimal efficiency. Read more to see how better data leads to better asset management for utilities of any size.
A car struck a fire hydrant in the middle of the night in California, creating a massive water leak. Even before first responders were notified, a pressure sensor sent a text alert to the water utility manager, who was able to dispatch a crew to the scene within minutes. What’s significant is that the utility responded long before receiving a call from emergency crews or an alert from its SCADA system installed in a nearby pump station.
Sniffer dogs have been used for a while in the oil and gas industry to find leaks. But recently, dogs have begun to be used to find leaks in water mains.
Business people love to talk about "disruption." They pride themselves on eating their competitors' lunch. Where their markets used to be about raving fans, now it's about inspiring craving fans, fueled by "hunger marketing" and the fear of missing out. There's a lot of dog-eat-dog philosophy...which is why it's important for companies to be willing to cannibalize their own technologies.
