Specifications include, but are not limited to: 9.1. Lammers Road Recycled Water Pump Station – The CITY has already acquired the necessary lands for the proposed Lammers Road Recycled Water Pump Station. The primary purpose of the proposed recycled water pump station is to provide sufficient pressure to boost the recycled water to the upper elevations of the City. Additionally, since the pump station will be located adjacent to the Byron Bethany Irrigation District’s (BBID) upper main canal, the secondary purpose is to utilize the BBID water by configuring the pump station to take water from the BBID canal. The proposed recycled water pump station shall consist of: • Multiple pumps with variable frequency drive (VFD) motors depending on the location of one or more pipeline terminus and shall be housed in a CMU building with redundant and reliable pumping systems. Provisions shall be made to add chemicals for dechlorination if the water is discharged to the BBID canal. • Roof shall be standing seam metal system and shall contain hatches. • Monorail and hoist shall be provided to move equipment, such as pumps and appurtenances, in and out of the building. • Pump station shall be connected to the City’s SCADA system using radio telemetry. Video camera system connected to the existing system for remote monitoring shall be provided. • Irrigation water shall be provided by connecting the irrigation system (for landscapes) to the existing water line along Lammers Road. • A building permit from the City of Tracy and electrical connection from PG&E shall be obtained for the proposed pump station project. • Pump station civil improvements include exterior fencing, security system, concrete and asphalt paving, and details for points-of-connection with conveyance system. 9.2. Recycled Water Pipelines – At this time, the CITY anticipates installing up to 24,000 feet of 8-to-30-inch diameter transmission recycled water pipeline, valves, meters, and other appurtenances, from the Lammers Road Pump Station to the southern portions of the CITY, including, but not limited to a: • Pipeline to transmit the recycled water to the recycled water distribution system. • Pipeline and/or turn out to discharge the recycled water to the upper and lower main. • Pipeline and/or turn out to discharge the recycled water to the Delta Mendota Canal (DMC). The pipeline design shall be in accordance with CITY’s Design and Construction Standards, AWWA Standards, State of California Water Code and “Purple Book”. The Proposer should expect numerous conflicts with existing utilities that must be resolved during the design, and account for said conflicts in the proposal. The design must include a construction/phasing element, whereby the project specifications provide a construction plan for the Contractor to limit disruption to residents, businesses, pedestrians, traffic, and water customers. The design must also include recommendations and solutions for maintaining the integrity of existing streets, and methods to ensure no trench settling after the project is completed.
