Joe Harris and Associates, PLLC has completed a feasibility study of the existing Hunley Creek pump station located in the Town of Hemby Bridge, in Union County, NC. The purpose of this feasibility study was to determine if there is sufficient capacity in the pump station for two proposed developments upstream of the station. The two developments combined propose to add an additional 325 homes and a club house to the pump station that have not been contracted for use of the pump station. EXISTING CONDITIONS Two forms of data collection were used to determine the existing conditions of the pump station. The first was an onsite visit to collect pump timings, dimensions and elevations of pump components. This data was then used to calculate the approximate flows of both the inflow and out flow of the station. From the pump on times and the rate the water levels were lowered, a pump flow rate was determined for each pump and the lower of the two flow rates was then used in subsequent calculations. A pumping rate of 590 gallons per minute was calculated for the smaller of the two pumps. Existing pump data was also provided from Union County Public Works. The data provided included pump run times over a two year period of time and approximate times of maintenance completed. Ths data was then analyzed and averages were taken to determine the available capacity of the station. From the data provided by Union County Public Works it was determined that a one month period of time had and excessively high reading. Charlie O'Cain of Union County Public works agreed that we would be able to eliminate the reading from the analysis. The remaining data was then averaged together to calculate an approximate average daily flow. The average daily flow was calculated by multiplying the average daily pump run times by the corresponding pum flow rate that was determined with the onsite data collected. The flow rate was then converted to Gallons per Day to show the flow rate based on the peak flow of the pump station. The Peak Flow was then divided by 2.5 to R. .1.(v.

The average daily flow value calculated is listed below: Average Daily Flow = 133,729 GPD CAPACITY Once the average daily flows were calculated the pump station and force main were analyzed to calculate the available capacity. The data collected at the pump station was also used to calculate the static head and pump station characteristics. An additional 101335 GPD were added to the average daily flow from proposed or previously permitted projects to the pump station. The approximate maximum and available capacity of daily flow with the addition flow are listed below: Maximum Daily Flow Capacity = 339,840 GPD Average Daily Flow Capacity= 90,475 GPD A recommended daily flow rate of 360 GPD for a single family home was then used to calculate the available capacity of the pump station. The approximate capacity is listed below: Available Capacity= 251 homes Based on the analysis of the pump station, with the purnp stations current configuration there is not sufficient capacity for the proposed developments. The approximate capacity that would still be needed for the developments is listed below: Build Out Capacity Needed = 94 homes or 33840 GPD loc.

If it is determined that the flow rate is excessive then the impellers can be modified to achieve the desired results.. To obtain the additional capacity that would be needed for the developments, the minimum flow rate for either of the pumps would need to be increased to 690 GPM. This increase in the flow rate would add an additional 57600 GPD. The approximate average daily flow is listed below. Possible Capacity . 411 homes or 148,075 GPD Capacity with Development = 72 homes or 26,075 GPD The additional capacity for the station was reviewed by Clearwater, Inc. and did not see any immediate concerns with the change of the impeller and the additional load to the pumps. cu2, Harris & iSCtLRLLC.
