To Whom it May Concern:
On November 1, 2018,the Division of Water Resources (Division) received an adjusted daily sewage
flow rate (flow reduction) request that would apply to all permitted but not yet tributary residential
connections and all future residential connections within the Highlands Cove WWTP service area.
In accordance with 15A NCAC 02T.0114(f)(2), the Division has evaluated the request as well as
additional information received on February 4, 2019, and based on the data submitted and the
Division of Water of Infrastructure (DWI)guidance,the Division hereby approves for use by the
Highlands Cove development an adjusted daily sewage design flow rate with the following
conditions:
• The flow reduction is applicable to residential single family dwellings only.
• The minimum flow for 1 and 2 bedroom dwellings shall be 120 gallons per day.
• Each additional bedroom above two bedrooms shall increase the volume by 60 gallons per
day per bedroom.
• This flow reduction shall not apply to sewer extension applications and/or permits for any
other public or private organizations whose wastewater flows are or might become
tributary to the Highlands Cove collection system.
I
Future sewer extension applications should be made using the flow reduction amount stated above.
All other aspects of the permitting process remain unchanged, and all applications must be in
compliance with the statues, rules, regulations and minimum design criteria as certified by the
owner and engineer.
Regardless of the adjusted design daily wastewater flow rate, at no time shall the wastewater flows
exceed the effluent limits defined in the NPDES Permit for the treatment facility or exceed the
capacity of the sewers downstream of any new sewer extension or service connection(s).
