  • Availability - With conventional sources of water such as surface and groundwater already under heavy stress in many areas around the world, the demand for water continues to outstrip current available supply. This mounting gap between demand and supply means significant opportunities exist to redirect and reuse municipal and industrial wastewater in order to create a more sustainable water source. Today, GE’s proven technologies in water reclamation, advanced wastewater treatment and reuse make it possible for municipalities and businesses to implement sustainable reuse programs that help them save money, generate new sources of revenue, and help address environmental concerns. Many leading municipalities and water agencies are leveraging GE’s expertise to safely reclaim, treat and redirect the treated effluent to a variety of applications, including agriculture and industry.Quality - With over 70 percent of the planet covered by water, many have viewed these bodies as a limitless supply. However, few have considered the impact of global warming, pollution and other activities that can impair that water which communities and industry rely upon. Today, the quality of our world’s ground water is becoming desperate. GE continues to develop advanced solutions that treat extremely impaired waters thus providing a high-quality water source that can be used for a variety of purposes.Environment - Increasing government regulations are requiring that industries such as chemical, refining, mining, and oil & gas reduce – or eliminate – the amount of potentially hazardous wastewater discharged at their sites. GE’s technologically advanced solutions treat impaired wastewater and manage water levels without discharging impurities, helping customers turn industrial wastewater into a new, high-quality water source that can be redirected into their industrial processes or safely discharged into the environment.Energy - Not only are water and energy resources critical to the well-being of the world’s growing population, they are also intrinsically dependent on each other. In simple terms, energy is required to produce water, and water is required to produce energy. With water demand tripling in the next 20 years and energy demand doubling over the same period, we must act now to stem the potential damage that could be brought about by this unprecedented growth. GE is providing comprehensive water/energy-related solutions, including on-site reuse technologies, wastewater-to-energy systems, distributed power, information management and remote monitoring, and diagnostics and control.In the end out customers are concerned with these mega trends, but they are very concerns with productivity …doing more with less.Productivity - As plant equipment and utility systems begin to age, operators seek ways to increase efficiency and productivity, and, ultimately, protect their assets and extend their life cycles. Water deficits cause additional constraints to productivity. GE is exploring ways to make industry more efficient through new water and process technologies and discovering new ways to help plants save energy and run more reliably. In addition, our researchers are focused on detecting, predicting and preventing plant malfunctions for safer, more productive and cleaner plant operations.
