Signing Official Title of Signing Official - 9 - Date Page 2 of b FTSE 10-18 Sewer Project Narrative For Walnut Cove Subdivision me Dept ofEnvironmental Quality FEB 10 29 Raleigh Regional Office The Walnut Cove Subdivision — Phase 2 at Spring I lope is a expansion to a residential development that consists of an additional 10 lots and will be located on a 4.89 Ac. parcel. The wastewater generated by this residential area was calculated using a daily flow of 80 gal/day per bedroom based on the Residential Flow Reduction Approval letter dated 1�ebruary 3rd, 2022 for the Spring Hope Collection System (WQCS00206). There are 3 bedrooms per lot bringing the daily flow for the project to be 2,400 GPD. It will consist of 100% residential flow. The sewer system will be constructed of approximately 495 LF of 8-inch SDR-35 PVC gravity sewer line including three new manholes. The wastewater treatment plant facility that will be handling this flow is the Spring Hope WWTF (Permit€ NC 0020061). The permitted flow for the WWTF is 0.4 MGD and after the allocation of the Walnut Cove -- Phase 2 Subdivision's flow the WWTF will operate at 33.6% of its total capacity. 86 sal7-- 0 s {}w o.. 1 AVAC 50 - { ,i -� // _ a BOW6' - 581 50 4' . 83 ` Phase 2 Ail `- SITE sTyfPo , y - E HASH ST I Oakdale Cem L% 82 ring Hope - _ 1A0'S7 _ J F • 4 t s� I k � I� 0 7 .1j 8 - 3ti set I - - -R£AM$ RDA 64 - _ � � N' J. 64 80 ■ \k | ~- , •® / ] r { 2 m 0 cm d § � / ,\tom G � © kk �� m � 0 4V $ clo. � a !
