Sudan°, P.E., Town Engineer Town of Holly Springs Post Office Box 8 Holly Springs, North Carolina 27540 RE: Town of Holly Springs Request for Adjusted Daily Wastewater Flow Wake County Dear Ms. Sudan: On March 15,1995, the Division received your wastewater flow reduction request and supporting documentation concerning wastewater flows associated with present residences within the Town of Holly Springs. Your letter requested the Division allow the reduction of wastewater flows from 120 GPD per bedroom as required in required by North Carolina Administrative Code to 255 GPD per household for single family residential units. In support of your request, water consumption data and wastewater information was supplied from households located in Holly Springs. An evaluation was completed by the Division in accordance with 15A NCAC .0219(1)(3) using the water consumptiondata submitted, twelve (12) months of data starting from January 1994. The peak month was determined to be January 1994 based on average wastewater generated per customer. Using the upper 10% of the water consumption data for the month of January, eliminating industries, commercial properties and several inaccurate residential readings, Division staff verified the flow rate of 255 GPD per household. In view of the information submitted, the Division. of Environmental Management hereby approves the use of 255 GPD per single family residence in all applicable non -discharge permit applications for future wastewater collection extensions which will be made tributary to the Town of Holly Springs Wastewater Treatment Plant 4Permit No. NC0063096). This consideration applies to any applicable future projects submitted to this Division as well as any projects which are presently under review, Wastewater flows presently tributary to the wastewater treatment facilities can be adjusted upon negotiations between the Town of Holly Springs and the Raleigh Regional Office.
