  Increasing the cyclic life of PVC force mains is essential for ensuring an economical and durable design. Various strategies can be employed by engineers in the design process to enhance cyclic life: Adjust Pressure Class/Pressure Rating: Engineers can opt for a lower Dimension Ratio (DR), which increases the pressure class or pressure rating. Updating maximum and minimum pressure values (Prs(max) and Prs(min)) based on the Joukowsky Equation or transient analysis is crucial in this approach. Optimize Pump Cycles: Reducing the number of pump cycles in lift-station or wet-well design contributes to extending the cyclic life of PVC force mains. Implement Surge-Control Equipment: Minimizing surge-pressure amplitude can be achieved by introducing surge-control equipment. Detailed information on surge-control techniques is available for a more comprehensive understanding. If thicker-walled pipes, such as DR 21, 18, 14, are utilized, the resulting cyclic life may be overly conservative...

  In the past few years, North America has experienced a series of catastrophic wildfires. Some of these fires have severely impacted water infrastructure, destroying above-ground appurtenances like water meters and hydrants as well as shallow-bury water service lines. As a result of wildfires, at least two California utilities have encountered water-quality issues in their water systems. The problems were caused by back-flow of contaminants through damaged service lines into water mains. The City of Santa Rosa published a report shortly after its wildfire event. The paper outlined the water-quality problems but was not complete in its analysis. This left a knowledge gap that opened the door for speculation and misinformation — the result was the publication of several articles that could politely be described as “not very accurate.” In March 2020, AWWA’s Opflow printed an article entitled, “Smoke and Water Don’t Mix,” that described research performed by the U.S. EPA and Califor...
