Public-private partnership will address water issues around the world
The U.S. Environmental Protection Agency (EPA) is one of 22 new members that has joined the expanded U.S. Water Partnership, announced on March 22 for World Water Day. The U.S. Water Partnership is a U.S.-based public-private partnership established to unite American expertise, knowledge and resources, and mobilize those assets to address water challenges around the globe, especially in the developing world.
Changes will allow units in multi-family homes to become certified
Continuing to build on the success of the WaterSense program, the U.S. Environmental Protection Agency (EPA) is making minor modifications to its specification that establishes the criteria for new homes to earn the WaterSense label.
Commercial reverse osmosis (RO) systems encompass a wide variety of applications. Some applications, such as metal plating or boiler feed water, require pure water with low dissolved solids. Other applications, in which a higher dissolved solids content is acceptable, such as car wash or drinking water applications, need to produce as much water as possible, or just enough water at the lowest cost possible.
Each of these categories presents unique challenges to commercial OEMs to configure systems that reduce the total water cost (TWC) to their customers.
New RO elements can lower total water costs
According to statistics published by the U.S. Environmental Protection Agency (EPA), water coolers across the U.S. consume about 6 billion kWh of electricity per year.1 Some water coolers actually use more energy than a refrigerator.
Lowering energy costs with efficient water coolers
This year’s winning projects for the second annual Top Water Quality Projects program come from all corners of the water treatment marketplace. These winners represent the most innovative and challenging projects submitted by readers to Water Quality Products (WQP) for recognition this year.
To be considered, all projects must have been in the planning or implementation phase in the past 18 months.
Hydrofracturing is not a new concept—in fact, it has been utilized by the gas and oil industries in the U.S. since the 1940s. Thanks to increased media attention, however, many are led to believe that this is a new technology developed specifically for the extraction of natural gas.
Evaluating gas drilling’s effects on groundwater and air quality
In the words of Alexandra Cousteau, “Water will be the defining crisis of our century.” Essentially, water is running out. Population is constantly growing, and water and storm water management costs are skyrocketing across the U.S., increasing by up to 8% per year. Without a sustainable water management plan that includes rainwater harvesting, both people and businesses will suffer.
System helps school become South Carolina's first LEED-certified educational facility
When McMaster University in Hamilton, Ontario, Canada, set about constructing its new Engineering Technology Building, it used the latest state-of-the-art technology not only to achieve U.S. Green Building Council Leadership in Energy and Environmental Design (LEED) Gold certification, but also to create a living laboratory to train students on the building systems of the future. One of the components is a rainwater harvesting system that collects, filters and disinfects rainwater for non-potable and potable use in the building.
First-of-its-kind system treats rainwater for potable reuse
Five years ago, the U.S. Environmental Protection Agency (EPA) launched WaterSense, a volunteer partnership program that promotes water efficiency to protect the nation’s water supply. Targeting manufacturers and consumers alike, the program has had an impact on the way Americans view water use. Leslie Streicher, associate editor of Water Quality Products, checked in with program leader Veronica Blette to learn about the motivation behind our changing water culture and what water efficiency means today.
A few weeks ago, the local electric utility visited my apartment building to give the residents free efficiency upgrades. The focus was not solely energy, however—in addition to replacing all of the building’s standard light bulbs with energy-efficient ones, the company installed free water-efficient faucets and showerheads in each unit.
