The HTH Solution shall be circulated in the reclaimed water main by opening the control valve and systematically manipulating blowoffs and taps at the reclaimed water main extremities. All reclaimed water leaving the system during this test must be disposed of through either an approved use or sent to the sanitary sewer. The HTH solution must be pumped in at a constant rate for each discharge rate so a uniform concentration will be produced in reclaimed water mains. iv. HTH solution shall remain in reclaimed water mains for no less than 24 hours or as directed by the Town of Holly Springs' Inspector. v. Extreme care shall be exercised at all times to prevent the HTH solution from entering existing reclaimed water mains. Bacteriological Sampling a) Free residual chlorine after 24 hours shall be at least 10 ppm or the Town of Holly Springs' Inspector will require that the lines be rechlorinated. b) Flushing of reclaimed water mains may proceed after 24 hours, provided the free residual chlorine analysis is satisfactory. Reclaimed water leaving the system because of line flushing must be returned to a sanitary sewer. Flushing shall be continued until an orthotolidine check (or other method approved by the Town of Holly Springs) shows that the reclaimed water mains contain only the normal chlorine residual. Samples for bacteriological analysis shall be collected by the Town of Holly Springs' Inspector 24 hours after flushing is completed. The Contractor shall furnish the sample bottles, the testing agency and such help as may be required to secure these samples. The Contractor shall 2015 ED&CS 11-19 Supp 12016 Supp # 2 Aug. 2017 Supp # 3 Aug. 2018 Supp # 5 Apr. 2021 also submit the test results to the Town of Holly Springs' Development Inspector. c) If test results are unsatisfactory, the Contractor shall immediately rechlorinate reclaimed water mains and proceed with such measures as are necessary to properly sterilize those reclaimed water mains. d) The new reclaimed water system shall be valved off from the existing reclaimed water system until a satisfactory bacteriological sample has been obtained and the Town of Holly Springs' Inspector has authorized the use of the new reclaimed water system.

The proposed project is in the north limits of the Reclaimed Service Area and is bordered by Woods Creek Road, and Highway 1, and Highway 540 -®£¤« 3¤³´¯ DMP performed the evaluations water system model in WaterCAD. The following setup was used for the modeling: wĻĭƌğźƒĻķ aƚķĻƌ {ĻƷǒƦ WRF Pumps off SFR Lots at Typical Demand (1.83 gpm/SFR due to average lot size being approximately 15,000 SF) Sequiris: 550 gpm (includes 400 gpm cooling and 150 gpm irrigation) WRF: 360 gpm (NPW uses + 200 gpm for RCW bulk filling) Twelve Oaks Pond: 500 gpm Ingenco: 53 gpm Burt Tract: Full build out active and in service (412 gpm) Hensley Tract: Full build out active and in service (214 gpm) Twelve Oaks Phase 09: Full build out active and in service (Stephenson) (150 gpm) Addison Subdivision: Full build out active and in service (Formerly Harris) (72 gpm) New Hill Road Subdivision (52 GPM) Carolina Springs PUD Phases 1-5 (296 GPM) Model Calculations: All modeling calculations were performed as a Steady State Model. Modeling as a Steady State Model provides for worst case demand condition, meaning that all demands in the model are active as part of the Scenario calculation. /ğƩƚƌźƓğ {ƦƩźƓŭƭ t…5 Based on CAD drawings provided to DMP by the Town of Holly Springs dated 07/31/2020 and additional information supplied to DMP on 09/29/2020, the proposed development includes five (5) Phases expected to be developed over the next seven (7) years. See attached Build-out Scenario Exhibit. The CAD information provided primarily consisted of Phase 1, which is also subdivided into five (5) Sub-phases along with an Eastern Leg to serve future phases. See attached Exhibit for phases. Technical Memorandum Page 2 DMP 200139 The layout provided to DMP was brought into the model as a backdrop. The reclaimed water lines and system nodes, with corresponding elevations, were then added to the model. Nodes on the property range in elevation from approximately 290 ft to 330 ft and are based on the information provided. At this time the Eastern leg extension of the Reclaimed Water System to serve future Carolina Springs PUD development is only being considered as a line extension. This includes the portion along Woods Creek Road as well as the Roadway Section A and Roadway Section C. While some minimal demands were investigated as part of the modeling, no demands are included as part of the line extension permitting. -®£¤«¨­¦ 2¤²´«³²Ȁ Carolina Springs PUD Eastern extension was modeled as a 12a 6 RCWL along Roadway Section A and Roaday Section C. The model assumed to Ingenco and a (Stephenson) Development. The model also assumed that the developments proposed and approved prior, as outlined under Reclaimed Model Setup, are active and in service. Based on the above described model setup, several scenarios were modeled and are described with their results summarized as follows: {ĭĻƓğƩźƚ Ѝʹ .ğƭĻ {ǤƭƷĻƒ Λ/{ t…5 9ğƭƷĻƩƓ 9ǣƷĻƓƭźƚƓΜ This Scenario assumes full build out all Sub-phases in Phase 1-5 from New Hill Road to Ivy Arbor Way RCWL installed from Ivy Arbor Way to Ingenco Results: Pressures are ğĬƚǝĻ 45 psi, which is the target system requirement minimum pressure.

As indicated with the analysis for Scenario 4, improvements within the existing RCW system will need to be completed as part of the full buildout of Carolina Springs PUD, Subphases 1-5 In order for the Town to be able to implement the full buildout of the Carolina Springs PUD additional improvements within the existing system Old Holly Springs Apex Road will need to be implemented. Additionally, one system component that should be monitored as part of the build-out for Carolina Springs PUD is the impact on the previously approved Twelve Oaks Phase 09. This system was designed to be installed with master meters, which require a 70 psi minimum, based on design information supplied to DMP at the time of review for Twelve Oaks Phase 09. With significant demands being placed on the system adjacent to and north of these master meters could potentially have impact on the operation of this system.
