Onsite residential and commercial graywater treatment systems for subsurface discharge |
|
|
|
This American National Standard, NSF/ANSI 350-1 Onsite residential and commercial graywater treatment systems for subsurface discharge Standard, has been developed as part of the ongoing efforts of interested parties to establish minimum requirements for onsite residential and commercial graywater treatment systems. The standard is intended to address public health and environmental issues only. Actual performance for any site or system may vary, depending on variations in raw water supply (such as in alkalinity and hardness), graywater constituents, and patterns of use. The end use of the effluent is the responsibility of the owner, design professionals, and regulatory officials.
