Residential Flow Reduction Approval
Chatham County
Dear Mr. MacConnell:
Per the proposed water use data based on the usage of EPA WaterSense fixtures and low-flow appliances
provided by MacConnell&Associates, P.C.,the Division of Water Resources hereby approves the use of a
480 GPD design flow for the proposed 5-bedroom home located at 117 Lexington Drive in Chatham County.
Please note that approval of this flow reduction does not constitute a modification to the previously issued
permit(WQ0031593-issued November 10,2016)with an approved flow of 480 GPD for a 4-bedroom home.
Regardless of the adjusted design daily wastewater flow rate,at no time shall the wastewater flows exceed
the effluent limits defined in the non-discharge permit for the treatment facility or exceed the capacity of the
sewers downstream of any new sewer extensions or service connection(s).
The granting of this flow reduction does not prohibit the Division from reopening, revoking, reissuing and/or
modifying the flow reduction as allowed by the laws, rules,and regulation contained in 15A NCAC 02T, NCGS
143-215.1,or as needed to address changed in State and/or Federal regulations with respect to wastewater
collection systems, protection of surface waters and/or wastewater treatment.
