The integration of photovoltaic (PV) water pumping systems into irrigation practices has emerged as a sustainable approach to addressing both water and energy challenges. These systems harness solar ...

Developed by Egyptian scientists, the PV-powered water pumping system may produce up to 181.8 m3 of water per day. The system consists of two PV arrays with each a capacity of 4.6 kW and a pumping ...

An international research group has proposed a low-cost testing methodology for solar water pumping systems that can reportedly improve water access in developing countries. The novel approach enables ...

Variable frequency drives (VFDs), also known as variable speed drives (VSDs), are used to modulate the speed of motors in various applications, from hydronic water pumping to VAV fan units to vacuum ...

I would like to thank Rebecca Ellis, P.E., for her 25 years’ worth of contributions to this publication. She has made, and continues to make, significant impacts on this industry, and I am grateful to ...

WATER SYSTEM. The production, purification, and distribution of potable water constitutes a "hidden system" in the infrastructure of the modern city. Until faucets run dry, or reservoirs are exhausted ...

Pumping an aquifer to the last drop squeezes out more than water. A new study finds it can also unlock dangerous arsenic from buried clays -- and reveals how sinking land can provide an early warning ...
