City of Santa Ana and fiber optic. The City has traditionally used radio but prefers to install buried fiber optic cables for communication between these sites, Identify all requirements for the options described including maintenance and operation related constraints. We understand that the City generally uses MDS NET II radio communications for site to site/home SCADA communications. 6. Prepare a preliminary underground data communication pipeline network plan at the John Garthe Pump Station. Tetra Tech will prepare a plan that identifies how the existing wells communicate to John Garthe Pump Station and how the new Well #32 will communicate to the pump station. All wells shall communicate to the main RTU at John Garthe Pump Station. Tetra Tech will provide recommendations for improvements to the communications between the existing wells and the John Garthe Pump Station. The improvement of these communication systems are beyond the scope of this project. 7. Prepare preliminary onsite sodium hypochlorite generation plans to disinfect the water used to fill John Garthe Reservoir. 8, Identify hydraulic conditions with the selected alternative to use in conjunction with the City Hydraulic Model to ensure satisfactory operations under normal operating conditions. We have assumed the following model runs with all the wells running at once is the worst case scenario, We will then run models without each of the high nitrate wells, Well #18 and then Well #24. We have assumed that Wells #36 and #39 will also be running since they have the low nitrate water. In the event that the pipe discharge line to Garthe Reservoir Is used to increase system headloss, material fatigue shall be considered a factor when selecting the pipe line material. 9. Prepare a schedule for Garthe Pump Station and Well #32 Operational Functional Specification and related deliverables for control programming related items. 10. Prepare preliminary horizontal alignment and vertical profile of water distribution main upgrades including all utility relocations. Minor storm drain improvements will be required for the drain to waste line during well startup procedures. We have assumed that we are tying into the existing drainiine and that a new drain line is not required, 11. Well pumping strategies shall be identified. Care shall be taken to limit well pump cycling given the operating constraints identified in the Study. 12. In the event that a pressure reducing/sustaining valve is determined to be necessary at John Garthe Reservoir per Alternative One (1) of the Study, site improvements and yard piping improvements will be necessary at the John Garthe Reservoir site. In addition, any site automation required to operate this valve both locally and through SCADA shall be subject to the requirements listed in the PLC Panel Design and Control Strategies section of the RFP. 13. Prepare park site improvements, preliminary horizontal alignment and profile of the parking lot that will be altered due to the construction and by adding a new well building at Morrison Park, 14. Preparation of a preliminary estimate of probable cost. 15, Preparation of preliminary staging for construction including a traffic management plan and traffic control plans. 16. Outline the preparation and submittal process of all required permits associated with getting the project approved and ready for construction. This Includes estimated time frames for processing said permits. 17. Prepare required documents and assist in Environmental approvals. In the event that an Environmental Impact Report (EIR) is deemed necessary, all necessary documentation will be prepared as required by CEQA. An initial study and mitigated negative declaration has been included in our proposal fee. A fee for an EIR shall be an optional item in the event that an EIR is required. 251-22
