Blame our fast food diets or restaurants’ negligence for what’s going down the drain. Whatever the cause, fats, oil, and grease (FOG) accumulation has become a pervasive problem for wastewater treatment plant collection systems.
Mapping the assets of a water treatment, water distribution, or wastewater collection and treatment system is just the means to an end. Maximizing value from that effort requires systematic planning and a healthy curiosity for looking into patterns of activity. Here are some considerations for turning raw asset data into more valuable benchmarks for better decision-making across multiple aspects of water operations.
Having to repair old, worn, broken, or leaking pipes is bad enough. Having to revisit the repair location a second time to refurbish the original fix is doubly frustrating. Here are some guidelines for getting the best results from pipeline repair efforts and enhancing the durability of the repair effort to match the anticipated service life of the pipeline itself.
Combined and sanitary sewer overflows are natural hazards for wastewater collection systems. Without a comprehensive solution to monitor troublesome conditions, overflows can be triggered with little warning and lead to expensive and embarrassing situations. Fortunately, versatile analytical systems that capitalize on existing wastewater collection infrastructure hold promise for avoiding such negative impacts.
The more a water utility knows about its current operations, the better equipped it can be to make more informed decisions about upcoming maintenance and capital replacement programs. Here are several key approaches to identifying cost-effective ways to make merging historical asset data and current operational data as the next step toward building a stronger, more resilient utility.
In many water industry applications, a supervisory control and data acquisition (SCADA) system is considered the heartbeat of the operation. As a result, many data management decisions revolve around what the SCADA system can or cannot do and how big of a deal and expense it is to change. Can’t there be a way to devise more ROI-responsive data solutions, without having to change SCADA solutions?
For all the talk about scarcity of source water, funding, and the next-generation labor pool in the water industry, there is one area that is not falling short — data collection. Here is how water and sewer districts inundated with data collected from a variety of central control systems, pressure loggers, and stand-alone sensors can streamline and manage that flood of data in ways that cut their major concerns down to size.
Most people understand the inherent benefits of plastic piping — chemical resistance, installation speed, ease of assembly, cost efficiency, longevity in corrosive, harsh exterior or underground environments, etc. Not everyone, however, fully appreciates the nuances of plastic piping design that help to maximize those benefits most efficiently.
Using historical data and Seeq analytical software, Nukon calculates when sewer blockages will occur up to 13 hours before occurrence, preventing spills.
Leprino Foods, the world's largest mozzarella cheese producer, operates two plants that share one wastewater pipeline – a 16” SDR11 High Density Polyethylene Pipeline (operating at approximately 160 PSI). During dirt work an “auger” hit the wastewater pipeline and drilled an 8” diameter hole in the line. Leprino needed immediate access to a repair fitting for this line.
The Great Lakes region was blessed with abundant freshwater for its rivers and lakes. Water as a resource and method of transportation were an important factor in Akron, OH, blossoming as one of America’s early manufacturing hubs during the late 1800s and early 1900s.
Among the pump stations managed by Branford, CT, is a long-term problematic station located at Burban Street. There were two primary problems at this station: 1) clogging from modern day trash and raggy, stringy materials, and 2) fats, oils, and grease (FOG) from a nearby nursing home and restaurants, which accumulate and float on the water surface, resulting in a horrendous mess.
