Pump Maintenance 101

| Maintenance will never be exciting. But it’s necessary work required to ensure that a pumping system operates when you need it. If pump operation was a football team, maintenance would be the offensive linemen who do the grunt work in the trenches of the scrimmage line and make possible the exciting plays and athletic prowess ...

Accessibility and Analysis

| The water industry has been “data-rich and information poor,” notes Graham Symmonds, chief knowledge officer for FATHOM. “That will continue without a reconceptualization of how, where, and why we’re using this data,” he adds. “A lot of work has to be done on utilities to be able to collect, curate, and analyze this data. There’s ... READ MORE

Looking for Leaks

| Water loss can be attributed to unbilled authorized consumption such as firefighting or flushing water mains, unauthorized consumption, and real losses due to leakage. All are examples of non-revenue water loss. ... READ MORE

Upon Closer Examination

| Never has it been more important to inspect and maintain hydraulic infrastructure. Never has it been harder in both remote rural areas and crowded urban environments to do so. Direct inspection of pipes and sewers is essentially impossible given the small diameter sizes of the pipes in question. Yet aging infrastructure is more prone than ... READ MORE

Efficiencies at the Water-Energy Nexus

| “The interdependence of water and energy forms a nexus or convergence that means efficiency measures in one area have the potential to produce additional efficiencies in the other, thus benefiting both water and electric utility customers as well as the environment.” American Water – Water-Energy Convergence: Efficiency Challenges and Opportunities Energy efficiency and how to pursue ...

Illuminating Technologies

| Around the time Galileo Galilei looked through his telescope and first spotted Saturn, another revolutionary idea was being explored when early scientists in 1614 realized that sunlight has powerful chemical properties. That early seed of a theory led researchers to explore the idea through the centuries, leading eventually to today’s ultraviolet disinfection technologies for water ... READ MORE

Tank Linings and Coatings

| Because water tanks are susceptible to corrosion, they benefit from a liner or special coating. The choice can depend on what material the tank is composed of, its location, condition, and cost. Whatever material is selected, it should create an impermeable barrier, fully adhere to the substrate, and seal all the gaps. In addition, manufacturers ... READ MORE

Intelligent Water Management

| There is an old saying, “If you’re so smart, why aren’t you rich?” Smart management of a water supply can greatly reduce operating costs and stretch municipality operating budgets, while providing superior service. The keys to being smart, the brains of the operation, are Automatic Meter Reading (AMR) technologies and Advanced Metering Infrastructure (AMI) systems. ... READ MORE

Critical Support

| We’ve all had it happen. Either ourselves or our neighbors have had their basements flooded during a major rainfall. To make matters worse, a lightning strike has taken out the neighborhood power grid, rendering the basement sump pump inoperable. It’s a helpless feeling to watch as the water rises up through the foundation. Whether it’s a small basement foundation or a major flood control levee, pumps are critical to the performance of hydraulic control structures. Except for those rare cases in which small-scale manual pumps are still employed, pump operation depends on the available power supply. For potentially critical situations, a ready backup power supply should be available to take over if the main power grid fails. But before these backup power systems can be appraised, the basic question of how much power a pump requires has to be answered. ... READ MORE

Recharging Our Water Resources

| Most states in the US have had long-established groundwater management regulations that all water agencies must comply with, except for California—until it adopted the Sustainable Groundwater Management Act (SGMA) in 2014. Agencies outside of the state are paying attention. ... READ MORE
