Worldwide licensing agreement signed for innovative wastewater treatment technology

American Water and Abengoa signed a worldwide licensing agreement for American Water's patented NPXpress technology.

VOORHEES, NJ, April 25, 2014 -- Today, American Water (NYSE: AWK), the nation's largest publicly-traded water and wastewater utility company, and Abengoa, a global company that applies innovative technology solutions for energy and environmental sector sustainability, signed a worldwide licensing agreement for American Water's patented NPXpress technology.

The agreement will enable Abengoa to use NPXpress to achieve wastewater treatment and nutrient removal in a sustainable way. American Water will retain all rights with respect to its NPXpress technology.

The NPXpress technology helps wastewater utilities, which are facing both increasing operating costs and more stringent environmental regulations, to reduce costs while improving the removal of nitrogen and phosphorus. Because the technology operates at lower oxygen levels, electricity consumption for aeration can be reduced by up to 50 percent.

In addition, the process can eliminate the need for costly chemical addition (methanol) by up to 80 to 100 percent. This process provides a more affordable and sustainable way of treating sewage. NPXpress is patent-protected in 15 countries and the EU.

This is the first time American Water has licensed an internally generated technology achieved through its Innovation Development Process (IDP). American Water's IDP program fills a vital need to seek innovative, cost-effective and sustainable solutions that can benefit all water utilities.

IDP combines research and development, technical expertise and infrastructure assets with innovations from both within American Water and from external business partners to create greater efficiencies in the areas of drinking water and wastewater. It provides a conduit for innovators to allow their technologies to be evaluated and to accelerate the adoption and market penetration of products or services that help solve pressing needs within the water industry.
