Residential Flow Reduction Approval
Guilford County
Dear Mr. Houk:
On June 25, 2007, the Division of Water Quality received a flow reduction request for residences in
the city of High Point served by the Eastside WWTP (NC0024210) & the Westside WWTP
(NC0024228). The letter requests an allowable flow rate of 240 GPD per 3 bedroom residential
connection based on the evaluated data from the WWTP and the active number of residential
connections.
The DMR data provided between January 2005 and December 2006 with daily readings taken during
November 2006 was analyzed by central office and regional office staff. Based upon this data the
Division hereby approves the use of 90 GPD per residential bedroom, with a minimum of 180 gpd
for one and two bedroom units in all applicable non -discharge permit applications. Flow shall be
incremented by 90/gpd for each bedroom above two. 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).
The residential water usage data include 13 residences with "0" flow. These residences were excluded
from the calculations. This resulted in an average daily flow of 150 GPD.
If you have any questions or comments regarding this matter, please contact Deborah Gore at
(919) 733-5083 ext. 593 [email: Deborah.Gore@ncmail.net].
Sincerely,
Coleen H. Sullins
