How can organizations finance the changes needed to preserve groundwater? In Brazil, where drought has left the countryside parched, farmers are being paid to improve infrastructure and implement groundwater preservation techniques.

In Brazil, about 60% of the country’s freshwater is used for crop and livestock production. With the understanding that poor  … Read More

Wooden water tanks were once ubiquitous on the urban skyline—cylinders standing guard like sentries above the rooftops. Today, however, it seems that water containment devices are increasingly tucked away behind walls and integrated into building design.

Most contemporary buildings pump water to large reservoirs in the top floors to make use  … Read More

From 2012–2016, the state of California was under the spell of one of the worst droughts in history. During this four-year time frame, we witnessed expensive media campaigns urging residents to reduce their use, and some cities in the Central Valley actually started rationing water supply for residents. With the  … Read More

Without a source of clean, safe water, neither individuals nor communities can survive. So perhaps the greatest invention of any civilization is a way to ensure clean, safe water. Supplying clean, potable water is both complicated and straightforward. The actual process is a relatively simple series of steps (extraction from  … Read More

Cellular respiration is one of the fundamental biological processes necessary for life. During this metabolic reaction, cells convert biochemical energy from nutrients into adenosine triphosphate (ATP). The process involves breaking down molecules and freeing electrons. The movement of these electrons affords opportunities for energy production.

Microbial fuel cells (MFCs) capitalize  … Read More

Perspective often grants us the vantage point necessary to observe things with clarity. When Carl Sagan described gazing back at the earth from space in Pale Blue Dot, many of us were, for the first time, able to visualize our home planet from afar and reflect on it in the context  … Read More

Pump System Longevity and Extreme Operating Regimes

Pump System Longevity and Extreme Operating Regimes

|

A pump is a mechanism that utilizes mechanical force to overcome distance, elevation, and friction to move water or another liquid through a conduit to a point where it can be discharged, stored, or utilized. Like all mechanical devices, pumps can wear out or break over time. A pump’s operational  … Read More

Water remains a scarce resource throughout the country. But it’s important, even for utilities that aren’t serving drought-stricken areas, to make sure that they are getting paid the right amount for the water they are delivering. It’s important, too, that they quickly identify and repair costly leaks throughout their systems.  … Read More
