Recently, Denver Water’s board approved its proposed “Lead Reduction Program Plan” to fully replace the estimated 75,000 lead service lines (LSLs) in their system within 15 years. The plan is an innovative solution that will remove the primary source of lead within Denver Water’s system, while avoiding the use of orthophosphate that can further exacerbate nutrient pollution problems in rivers, streams, and oceans.
The City of Aurora is home to over 370,000 people and is Colorado’s third-largest city. Their wastewater system consists of approximately 1,100 miles of underground piping network.
Are your current pressure-boosting pumps the best design for your operating conditions? Are they maximizing value from your operating budget with peak efficiency? How can you know for sure, and what can you do if they are not? Here are some guidelines for evaluating performance efficiency in pressure-boosting applications and for choosing the best pump configurations for new or existing applications.
Electromagnetic meters (mag meters) are well established in terms of highly accurate performance for a variety of municipal and industrial water applications. Differences in their construction formats, however, dictate how easy they can be to install, maintain, and calibrate. Compare these three options to see the value of full-profile-insertion (FPI) mag meters and their associated advantages in real-world use.
When it comes to metering water flow — drinking water or wastewater — full-bore mag meters offer many advantages. While the underlying technology based on Faraday’s Law of electromagnetic induction is shared among all styles of full-bore mag meters, specific implementations have impacts on longevity and accuracy. Here is what to look for when the time to choose arrives.
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.
Even as numeric modeling gets more advanced, physical modeling remains an important, continually evolving aspect of hydraulic engineering.
When space is tight and straight-run piping is at a premium, V-Cone differential pressure (DP) meters are an excellent choice — especially where the potential for turbulence raises metering accuracy issues with other conventional meter styles. This article describes how to satisfy some challenging water infrastructure applications with V-Cone meter accuracy at a low permanent pressure loss.
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.
The main challenges of water utilities are the same as they have always been—struggling with aging and insufficient infrastructure, while trying to deliver safe, reliable, and cost-effective service. There are some things that are increasingly influencing the complexity and risks associated with these challenges, like population shifts and land-use changes from rapid urbanization, increases in extreme hydrometeorological events and natural disasters, and increased public expectations and government regulations.
