Connecticut's "Guidelines for the Design and Operation of Public Water System Treatment, Works, and Sources" require water meters installed by public water systems to be tested and certified in accordance with Standard 61 Section 8 of the standards issued by ANSI/NSF.
-
Connecticut adopted NSF Standard 61 Section 8 compliance requirements to minimize the amount of lead leached from water meters and other plumbing fixtures into public drinking water systems.
-
Traditional water meters made from waterworks bronze (UNS C-84400) contain 6% - 8% lead by weight and do not comply with NSF Standard 61 Section 8.
-
Neptune meters are constructed from a no-lead high copper alloy that was developed by the Copper Development Association to minimize lead content in the alloy and the potential for lead leaching from plumbing fixtures. This no-lead high copper alloy reduces the lead content in the alloy used for Neptune meters to less than ¼ of 1% by weight. All Neptune meters made from a no-lead high copper alloy have been tested and certified as complying with NSF Standard 61 Section 8.1
-
If public water systems in Connecticut install water meters that do not comply with NSF Standard 61 Section 8, they are subject to potential enforcement action initiated by the Connecticut Department of Public Health and potential claims from customers for failure to comply with the regulations.
-
If public water systems have questions about compliance with NSF Standard 61 Section 8, they should contact the Connecticut Department of Public Health at 860.509.7333.

Neptune has retained the San Francisco law firm of Barg Coffin Lewis & Trapp, LLP, a firm specializing in environmental matters and experienced with NSF Standard 61 compliance issues, to assist it in providing service to its customers and potential customers regarding NSF Standard 61 compliance.
