The specific modifications requested are needed due to: 1. The proposed force main route has been changed, and it will discharge into a different receiving manhole. The force main length has been reduced from the permitted length. 2. The design flow has increased from permitted 12,000 gallons per day to 50,500 gallons per day, due to a proposed Town of Fuquay Varina Community Center that will be constructed adjacent to the school. None of the permitted pump station equipment will be changed due to the modifications described above. The revised force main alignment and length will decrease the total dynamic head conditions for the permitted pumps, causing them to pump at an increased rate. The increased rate will be sufficient for the increased tributary flows. The enclosed application reflects the increased design flow and pumping rate in Section VIII.3. and VII1.4. For this project, there are two engineer certifications since Stewart, Roy Lorenzen, P.E. is the listed design engineers for the gravity sewer and Diehl & Phillips, John Phillips, is the listed design engineer for the pump station. Although it is not required, we are including the Design Report prepared by Diehl & Phillips that has detailed information for the pump station design.

For POTWs that implement a pretreatment program, include flows allocated to industrial users who may not be using all of their flow allocation. Please contact your Pretreatment Coordinator for information on industrial flow tributary to your WWTP. As of January 15, 2008 the POTW should have reviewed flow allocations made over the last two years and reconciled their flow records, to the best of their ability, so it is known how much flow has been obligated and is not yet been made tributary to the WWTP, in accordance with local policies and procedures employed by the reporting entity. e.

Calculate the total current flow plus obligated flow (D=B-C) and the available capacity (E=A-D). Include the proposed flow for this project with other obligated flows that have been approved for the pump station but are not yet tributary (C). Firm capacity is the maximum pumped flow that can be achieved with the largest pump out of service as per the Minimum Design Criteria. Design Average Daily Flow is the firm capacity of the pump station divided by a peaking factor (pf) of not less than 2.5. If the available capacity (E) for any pump station is < 0, then prepare a planning assessment for that pump station if the system has future specific plans related to capacity that should be considered in the permitting process.

A planning assessment for Kaw Creek PS (see example data above) may be performed to evaluate whether there is significant likelihood that needed improvements or reductions in obligated flows will be in place prior to activating the flows from the proposed sewer extension project. If the system decides to accept the flow based on a planning assessment addendum, it is responsible to manage the flow without capacity related sanitary overflows and must take all steps necessary to complete the project or control the rate of flow to prevent sanitary sewer overflows. The planning assessment may identify a funded project currently in design or construction, or a planned project in the future not yet funded but in a formal plan adopted by the system. The system should carefully weigh the certainty of successful timely project completion for any expansion, flow management diversion or infiltration and inflow elimination projects that are the foundation of a planned solution to capacity tracking and acceptance compliance. For example: Given that: a. The proportion and amount of obligated, not yet tributary flow accounts for 24 % and 0.080 MGD of the committed flow in Pump Station Kaw Creek; and that b. The rate of activation of this obligated, not yet tributary capacity is currently approximately 0.01 MGD per year; and that c. A funded capital project that will provide the required planned capacity, namely is in design or under construction with planned completion in ; and/or d. The following applies: The master plan and ten year capital plan contain recommended scope and funding for a capital project entitled Kaw Creek DmR Station pXgrade with funding Tanned in July 2014. This project is planned to add 0.100 MGD to the firm capacity of the pump station by October 2015. Inclusion of this proposed capital project as a condition of this Flow Trackin Acce tance for Sewer Extension Permit Application elevates this roject's priority for funding and construction to be implemented ahead of the activation of obligated, not yet tributary flows in amounts that exceed the firm sumo station capacities identified in Section II above. Therefore: Given reasonably expected conditions and planning information, there is sufficient justification to allow this flow to be permitted, without a significant likelihood of over -allocating capacity in the system infrastructure.

It seems like a lot of this information Dorothy Robson with DWR (who worked on the previous permit) asked for with the original permit application (and maybe you folks just used most of your original uncorrected application with this submittal?). Here is a link to the original application with the corrections/information: https://edocs.deq. nc.gov/WaterResources/DocView.aspx?id=3019540&dbid=0&repo=WaterResources&searchid =89bbf5de-482b-417e-a678-fad7f85a40ee If you could make sure to include and/or correct the following: 1. Part V.1. of the application -maybe you meant a downstream sewer number of WQ0019215? We have one for Fuquay-Varina for that number, it is listed as Woodchase Subdivision (not sure that is even correct for the area of the school)? 2. Part VITA. of the application -we cannot permit 6-inch gravity sewer as a publicly owned sewer. Based on a review of your previous application -this seems to be removed (possibly done as a stand alone building?). Please review and correct as necessary. 3. Part IX.4. if this project is in the Neuse Basin -then it is subject to State buffer rules (there may be some confusion in how you're answering this - should be "YES" and then you should indicate if it complies or not). 4. Part IX.5. Please reference the 401/404 number for this project. 5. You may wish to review the answer indicated Part IX.6 and correct if necessary. If it does not comply with additional permits, please explain. With signatures from 2 different PE's-you indicated For Forcemain Design Only and John Phillips indicated for Pump Station Design Only. Who is signing off on the gravity sewer portion? 7. Please supply a topo map and sewer flow diagram indicated where the school will tie-in to the main line (and an outline of the project area). This application needs to be a stand-alone document, so please include the requested information. Feel free to contact me if you have any questions or if I can clarify anything.

There have been two revisions to the original design parameters: 1. The design flow rate has increased from 17,000 gallons per day to 50,500 gallons per day (average daily flow rate). 2. The force main route has been changed to have a lesser length of pipe and a reduced static head. The pumps selected for the original design conditions are Sulzer Model 80C-CB1, with No. 4 Impellers (impeller diameter of 7.06 inches). These pumps were purchased and delivered to the project prior to the decision to revise the force main route. The attached calculations confirm the purchased pumps and all other features of the originally designed pump station will be sufficient for and compatible with the increased design flow and revised force main route if the following modification is made: 1. The float switch elevations should be revised to provide an increased operating volume between the "Pump Off" and "Pump On" levels. The revisions should be as listed below: Float Switch Name Original Design Elevations Revised Elevations High Water Alarm SCADA 361.65 361.65 High Water Alarm(panel) 361.15 361.65 Lag Pump On 360.65 361.15 Lead Pump On 360.15 360.65 Pumps Off 359.15 359.15 The previously selected and provided pumps will deliver a greater flow rate than originally calculated due to the decreased total dynamic head, and they are suitable for the revised pumping conditions. F. Phillips, P.E. Diehl & Phillips, P.A. Page Iof11 Hilltop Needmore Road School Pump Station Design Report (Updated to Reflect New Design Flow & Changed Force Main Route) WK REVISED ]UNE 17, 2024 The updated design flow for the pump station is 50,500 gallons per day, which reflects both the flow from the new school as well as the Town of Fuquay-Varina's Community and Senior Center. The proposed force main route now has the force main leaving the pump station, turning southward along Brushy Meadow Drive, turning eastward along Spring Crest Court, and then extending southward through easements to an existing gravity sewer manhole. The length of the proposed force main route is approximately 4,271 LF. The elevation of the force main discharge into the existing manhole is approximately 328.00. There is an intermediate high point in the force main at Station 24+70, with an elevation of approximately 359.00 (beside Spring Crest Court, just before the force main turns into the easement). A combination air valve will be required at this location. The calculations for the pump selection will examine pumping to this intermediate high point, as well as pumping to the receiving manhole, to determine which condition controls the pump selection. The force main design by Stewart proposes to use 4-inch HDPE DR9 IPS, which has an inside diameter of 3.44 inches. The minimum flow rate to provide a 2 f/s flushing velocity in the force main is 58 gallons per minute. The minimum pumping rate for a design average daily flow of 50,500 gpd is: 50,500 gpd x 2.5 peaking factor = 88 gallons per minute 88 gpm > 58 gpm, confirming the minimum required pumping rate will provide a sufficient flushing velocity for the force main. Calculation of System Head Curves for the revised force main route: The Pump Station & Valve Vault Piping equivalent lengths are as calculated below.

This holds true if the Hazen -Williams "C" factor for the piping is 120. If the "C" factor is 140, the intermediate high point TDH values are greater for flow rates up to 112 gpm, and then the full force main system creates greater TDH values for flows greater than 112 gpm. Based on this information, the system head data above can be combined to produce system head curves that represent the controlling total dynamic heads for the applicable range of flows.

If the "C" factor is 140 (more typical of new pipe), it is anticipated the pump will deliver 103 gpm against 36.7 feet TDH. Both estimated flow rates exceed the required design flow rate of 88 gallons per minute. The pumping rates determined above are based on the force main being completely filled with wastewater and all air being expelled from the pipeline. If there are any trapped air pockets in the force main, the actual pumping rates may be less than predicted. However, as long as the pump rate equals or exceeds 88 gpm, the station will have the required capacity. One aspect of this force main profile that is somewhat unique is the force main has an extended downhill section as it leaves the school site. The profile indicates the force main between Sta 0+80 and 5+10 (approximately 430 LF) can drain empty between pumping operations if sufficient time passes. When a pump starts under these conditions, the pump will operate at a higher flow rate due to the low head conditions presented by the empty pipe. The initial pumped flow will begin to fill the empty section while the air in the section is exhausted through the combination air valve at or near Sta 0+80. The downhill liquid flow filling the pipe will have the escaping air flowing in the opposite direction towards the air valve. The result is an unsteady, non -uniform flow rate that can't be readily calculated. Such calculations are not necessary, as it is only necessary to confirm the pump motor will not overload (exceed its full load ampere rating due to the high flow - low head conditions. This can be checked by calculating the pump flow rate for the force main system between the pump station and the high point at Sta 0+80. This calculation will determine the maximum flow -minimum head conditions the pump could experience. The calculation is presented below (only checked with a "C" factor of 140, as that will provide a higher flow - lower head condition than a "C" factor of 120).

The pump curve on the following page presents the graphical solution for the system head curve that will existing when re -filling the drained portion of the force main. The exhausting of the air in the force main may inhibit the fill rate of the pipe, which would only move the operating point leftward on the pump curve, decreasing the ampere requirement of the motor. Once the drained section is re -filled, the force main can be fully pressurized and the pump rate will decline to 89 gpm to 103 gpm, depending on the actual "C" factor of the piping. The volume of the drained section of the force main is approximately 208 gallons. There will be a minor amount of flow out of the force main as the drained section is filled, but the force main should be pressurized within a minute if the air is efficiently exhausted.
