There are currently 152 recreation vehicle (R.V.) spaces and 27 tent camping spaces at Mayflower Park. There are restroom, shower facilities and a dump station at the Park. The R.V. spaces currently direct wastewater to the dump station. The wastewater from the dump station, restroom and shower facilities is directed to a septic tank and drain field located within the Park area. The purpose of the Mayflower Park Sanitary Sewer Improvement Project (Project) is to construct a gravity sanitary sewer pipeline system, sanitary sewer pump station and sanitary sewer force main to collect the Mayflower Park facility wastewater. The wastewater will be directed to an existing City of Blythe 8-inch diameter sanitary sewer force main located along Sixth Avenue. Ultimately, the wastewater will be conveyed to the City of Blythe Wastewater Treatment Facility. The existing Mayflower Park septic tank and drain field will be abandoned and decommissioned in accordance with County of Riverside Health Department requirements. The abandonment and decommissioning of the septic tank and drain field is included within the Project scope of work. The Project includes the installation of 1,668 lineal feet of 8-inch diameter SDR 35 PVC gravity sanitary sewer pipeline and 10 manholes. The majority of the gravity sanitary sewer pipeline is between 6 to 10 feet below finish grade. Sewer laterals extending from the dump station and restroom and shower facilities will be connected to the 8-inch diameter SDR 35 PVC gravity sanitary sewer pipeline. The 8-inch gravity sewer pipeline collection system will direct wastewater to an 8-foot diameter, 20-foot deep pre-cast concrete wet well. A 150 gallon per minute, 10 horsepower duplex, self-priming abovegrade pump station will convey the wastewater through a 4- inch diameter, 3,049 lineal foot force main to an existing City of Blythe 8-inch wastewater force main located along Sixth Avenue. Electrical power will be directed from existing Mayflower Park electrical facilities to energize the wastewater pump station. A 2-inch water service will be extended from the existing Mayflower Park irrigation system to the pump station to provide wash down water. A local visual/audible alarm will be provided at the pump station for pump failure and high water alarm functions; however, accommodations to transmit the alarm functions to an outside location (such as the City of Blythe Public Works Department or Wastewater Treatment Plant) will not be provided unless the alterative bid item for this work is awarded. A light pole and luminaire will be provided at the pump station site for nighttime operation and maintenance purposes. A class 2 base entrance road and maintenance area will surround the above-grade self-priming pump station. A 12-inch diameter, SDR 35 PVC gravity pipeline will be extended for a distance of 40 feet from the wet well to serve the 59 acres of undeveloped Park area in the future.
