BACKGROUND The City has requested modification of the City's existing Supervisory Control and Data Acquisition (SCADA) system to incorporate two new Remote Telemetry Units (RTU's). Modification covered under this scope of services includes programming of the Hook and Pitt Street site Programmable Logic Controllers (PLC's) and modification of the WTP Wonderware Human Machine Interface (HMI) software to incorporate the operation of these two sites into the existing system. Also included in this scope is PLC programming modifications to the Grand Highway and 4th Street Well sites. In addition Tetra Tech will program the HMI and PLC of the new supplemental reuse supply well located at or near the Eastside Water Reclamation Facility(WRF). Services to be completed are further described herein and shall be performed in accordance with the City of Clermont/Tetra Tech, Inc. professional engineering services agreement dated October 13, 2009. II. SCOPE OF SERVICES INTERCONNECTION STATION PROGRAMMING A. PLC and HMI Control Programming Tetra Tech shall provide PLC and HMI programming to achieve the following overall system operation: Overall system operation is intended to maintain acceptable levels within the West Area Elevated Storage Tank(EST)as follows: 1. Establish a sequence for the four potential sources including only those currently in AUTO as follows: a Grand Highway Well. This will normally be the lead source. b Pitt Street and Hook Street Interconnects These will normally be the lagl and lag2 sources with automatic alternation between them c 4`" Street Well. At selected times of the day, this will be included © TETRA TECH Tt#BP Clermont/E-W PRV Interconnection -1- 022514 well and interconnection stations programming scope in the sequence as a fourth source positioned within the sequence as elected by the operator via a software switch. Provide an operator controllable time of day switch that defines when this source shall be included 2. Provide the following operator adjustable parameters associated with the EST level: a LSL1 —Level at which water is to be supplied b LSL2—Level at which the lagl source is to be called c LSLL—Level at which all available sources are to be called d LSH—Level at which the tank is full and all supply sources should be stopped 3. When the EST level falls to LSL1 for a preset time, call for the lead source to start. 4. If the level falls to LSL2 for a preset time, call for the lag source to start. 5. If the level falls to LSLL for a preset time, call for all available sources to start. 6. Stop all sources when the level reaches LSH for a preset time. B HMI Graphic Screen Modification 1. Modify the existing "Elevated Storage Tank and Wells" SCADA HMI graphic screen to incorporate the new supply sources. 2. The existing display contains, among other items, a panel for each of three wells. One of these, Seminole. Is being de-commissioned and shall be removed from the screen. 3. Two new panels shall be added to the screen for the two new PRV sites. These shall be similar to the existing well site panels except as follows: a. Indicate East and West pressure readings. b Indicate current position in the control sequence. c The H/O/A switches open and close the site's PRV rather than starting or stopping the well pump. d The well pump running or stopped indication is replaced with PRV opened and closed indication. e Delete non-applicable indications (e.g. run time ETM, Chlorine Leak, etc.). 4. Modify the 4th Street panel to incorporate indication and control functions © TETRA TECH Tt#BP Clermont/E-W PRV Interconnection -2- 022514 well and interconnection stations programming scope required by the new time of day operation control strategy. 5. Modify the alternation display panel to reflect the revised control sequence. 6. Delete portions of the leftmost panel that are no longer applicable. C System Training Training will include one eight hour day of onsite training on the following: 1. Use of the system, including the new graphic screens. 2. Specific training for the actual hardware configuration to provide a detailed understanding of how the equipment and components are arranged, connected, and set up. 3. Troubleshooting and diagnosis. 4. Component removal and replacement. 5. Periodic maintenance. D System Testing Tetra Tech will provide system testing as follows: 1. Field Acceptance Testing: a. Provide 5-days of onsite startup of PLC and HMI software. System will be tested to confirm compliance with the above described overall system operation. b After the system has been in service for several weeks Tetra Tech will provide 2-days of onsite system follow-up troubleshooting of system software. E. Assumptions 1. Proposed radio system shall be programmed and certified operational by contractor before onsite Field Acceptance Testing shall begin. 2. Tetra Tech services under this contract shall include PLC programming, Wonderware HMI programming, factory/field acceptance testing and training. WELL PROGRAMMING A. PLC and HMI Control Programming © TETRA TECH Tt#BP Clermont/E-W PRV Interconnection -3- 022514 well and interconnection stations programming scope i 1 1 Tetra Tech shall provide PLC and HMI programming to achieve the following system operation: Overall system operation is intended to maintain acceptable levels within the Eastside WRF Ground Storage Tank(GST) as follows: 1.
