Water Main / Fire Line Rehabilitation
Problem Dirty brown water and poor water flow were the first clues that a mid-Atlantic commercial property owner had a problem. Then the owner was put on notice by the local fire department that the water supply lines were no longer meeting the required flow requirements. Four hydrants on the owner’s property were flowing between 200 to 300 gallons per minute due to heavy corrosion-induced ...

Water pressure too low: Possible causes and remedy
In the physical sense, water pressure is the hydrostatic pressure in water. It increases with increasing water depth and is referred to as the water column and measured in meters of water column, mH2O or mWS for short. A meter of water column is about 0.10 bar. In everyday life, water pressure refers to the the force applied per unit area with which the fresh water - alternatively also called tap ...

What makes high-risk pipelines deteriorate to a state of failure?
According to AWWA's 2016 Benchmarking Survey, the average water and wastewater utility has seven breaks per 100 miles of piping every year. Tip-top systems experience just four breaks in that distance, while those at the bottom have 18. While it’s interesting to note the difference in break rates, it’s unfair to compare one utility to another, as a multitude of factors come into play ...

Analysis of the chemical form of iron in water pipes using XAFS measurements
Yellow and red metal oxides are commonly found on deteriorated water pipes and it has been reported that their main component is iron. X-ray absorption fine structure (XAFS) spectroscopy is an effective method which can be used to measure the chemical form of metals. However, when the iron concentration in water samples is extremely low, XAFS measurement and analysis can be difficult due to ...

Ping-Ping, What’s That Sound? Acoustic Fiber Optic Technology Helps Identify Problematic Water Mains
With the deteriorating state of many aging water mains found in cities across North America, urbanites are frequently witnessing unexpected plumes of water erupt as man-made geysers in their own metropolitan backyards. While natural geysers are awe inspiring, urban geysers are much less so, due to their destruction to property, roads and the environment. Because an uninterrupted water flow is ...

Making Every Drop Count: Unitywater uses leak detection as a foundation for condition assessment
It stands to reason why many utilities respond to leaks only after they receive a call about water gushing from a street or a complaint from a customer about a damp basement, or other signs of visible leakage. Human nature reflects the adage that is often easier to respond to an issue rather than to proactively seek ways to mitigate the potential problem before it happens. Let sleeping pipes ...
