Peak Wet Weather Flow Management — A Slow And Painful Process
5/18/2020
The water and wastewater industry is not like most businesses. Our industry is driven by many factors, including environmentalist concerns, federal and state regulatory water quality requirements, and utilities being good stewards of our waterways and providing clean water for drinking and recreational use. We have accomplished a lot of great work to clean up our waterways and provide safe water since the Clean Water Act (CWA) was first passed.

Using AI To Reduce OPEX In Wastewater Treatment
4/28/2020
For municipal and industrial wastewater treatment managers and support staffs, the prospect of using artificial intelligence (AI) to guide better decision-making sometimes seems more like a distant promise than a ready solution. Here are some insights on how AI can use historical data to improve operational intelligence and optimize processes, plus guidelines on how water professionals can do more to harness that power sooner.

Turning Problematic Groundwater Treatment Into A Cost-Saving Resource
4/22/2020
Receiving a compliance order from the California Water Board’s Division of Drinking Water (DDW) was not the worst thing that ever happened to the City of Lemoore. It set the wheels in motion for a unique technical solution to historic groundwater problems and a progressive design-build approach to accelerating delivery of high-quality drinking water with only one-fourth the operating expense (OPEX) of other treatment alternatives.

How Much Can Leak Detection Reduce Non-Revenue Water Losses?
3/19/2020
Utilities that choose not to install proactive leak detection know exactly how much they are ‘saving’ by avoiding that investment. Unfortunately, they often have no idea of how much they are actually ’paying’ to forego it, since 65 to 75 percent of water leaks never surface to prove their hidden expense. Now, with challenges related to water scarcity, regulatory reporting demands, AMI implementation, and an increase in aging infrastructure, it’s a better time than ever to reevaluate those costs.

How pH Standards Impact The Accuracy Of Water Quality Measurements
3/4/2020
When it comes to pH measurement in water and wastewater treatment, there are two focal points for the word ‘standard’ — one is a compliance-related state or federal water quality specification; the other is a specific fluid used as a calibration reference point to ensure pH instrumentation accuracy. Here is why both are important and how they affect the best pH measurement outcomes in both areas.

The Importance And Impact Of Accurate pH Measurement
3/2/2020
Across many water-quality measurements — from free chlorine residual to disinfection byproducts, etc. — pH is an underlying factor affecting many water treatments and compliance testing results. Here are some guidelines for maintaining accurate pH readings to assure cost-effective treatment and final water quality despite changes in source water composition, treatment protocols, or other factors.
