(CMI) is pleased to submit this proposal for performing engineering and <br />construction phase services for the above referenced project. The proposal is based on our <br />understanding of the project provided in the Manning Preliminary Evaluation and our site visit <br />on September 15th. The tasks include engineering design services and construction phase <br />services for the rehabilitation of Lift Station No. 8 and Lift Station No. 32. For your <br />convenience this proposal consists of General Overview, Scope of Services, and Schedule. <br /> <br />GENERAL OVERVIEW <br /> <br />Based on information and data provided by the previously developed Manning investigation and <br />our field visit, Lift Station No. 8(L.S.#8) receives flow from the Creekmont Subdivision and <br />commercial development along Myrtle Creek, Underwood and Spencer Highway. We <br />understand that there are approximately 508 existing equivalent connections, an average daily <br />flow of approximately 177,800 gpd and a peak flow of approximately 494 gpm. Ultimate build- <br />out of the service area will provide approximately 618 equivalent connections, an average daily <br />flow of approximately 216,300 gpd, and a peak flow of approximately 601 gpm. <br /> <br />Lift Station No. 32(L.S.#32) is located on Underwood Road and receives flow from Spenwick <br />Subdivision and the commercial areas along Underwood and Spencer Highway. L.S.#32 also <br />receives flow from Lift Station No. 33. The lift station serves approximately 394 equivalent <br />connections currently with average daily flows of 137,900 gpd and a peak flow rate of <br />approximately 383 gpm. Future growth in the area will ultimately increase connections to 512 <br />equivalent connections with average daily flows of approximately 179,200 gpd and a peak flow <br />of approximately 498 gpm. <br /> <br />These lift stations are currently wet welll dry well type stations with Gorman Rupp suction lift <br />pumps. We understand the City desires to rehabilitate the existing lift stations by removing the <br />existing mechanical equipment, backfilling the existing dry wells, and installing new <br />submersible pumps and associated mechanical equipment.
