EPA joins with several organizations to improve wastewater treatment for 25 million homes

"This agreement will help solidify our national partnership to protect drinking water supplies and local water quality through promoting change in the way these waste water systems are managed," said EPA Assistant Administrator for Water Ben Grumbles. "I am pleased to formally recognize the contributions these partners make to achieve results in protecting public health and improving water quality."

The memorandum of understanding (MOU) is a first step in implementing EPA?s program that works cooperatively with national organizations that represent septic system practitioners and the public. These systems are used in nearly 25 percent of homes across the country and used in about one-third of all new housing and commercial development. When properly sited, designed and maintained, these systems are capable of producing high quality wastewater. However, decentralized systems are the second greatest threat to groundwater quality, second only to leakage from underground storage tanks. It is estimated that nation-wide, 10 to 20 percent of decentralized systems are not adequately treating wastewater due to inadequate site location, design and maintenance.

The program strategy that accompanies the MOU identifies EPA?s vision, mission and actions to improve the performance of decentralized wastewater treatment systems. The MOU and the strategy are intended to upgrade the management of these systems and facilitate collaboration between EPA headquarters, EPA regions, state and local governments and national organizations representing practitioners and assistance providers. Improved performance of decentralized systems will provide better protection of public health and water resources.
