1 10 March 2011 Water & Sewer Commission CITY OF FREEPORT, 230 WEST STEPHENSON STREET, FREEPORT, ILLINOIS TELEPHONE: Dear Consultant: The City of Freeport Water and Sewer Commission is presently accepting proposals for services in the design and specification of a new Supervisory Control and Data Acquisition (SCADA) System. The current system has been installed over the last 25 years and is used to monitor and control 4 sites. There are 12 Pressure Reducing Valve stations which are currently being added into the system. Additionally, one well is being added at an existing location and a standpipe is being replaced by an elevated tank. The Commission wishes to install a fully automated control system for the water utility. An additional telemetry master will be installed at the Wastewater Treatment Plant for communication to 9 lift stations. The lift station upgrades should be part of this design project and included as a bid alternative. The wastewater treatment plant should also be examined for upgrade, the current system is a proprietary Krueger system installed in Responses to the enclosed Request for Proposal and Qualification shall be submitted to the City of Freeport, City Clerk s office, 2 nd Floor, City Hall, 230 West Stephenson Street, Freeport, IL 61032, no later than 3:00pm, March 23, The proposals shall be presented in a sealed envelope clearly marked City of Freeport Water & Sewer Commission: SCADA Upgrade The design firm shall provide 1 electronic copy of the proposal on a CD and 5 bound 8.5 X11 hard copies of the proposal.

2 Request for Qualification and Proposal Water System Monitoring, Control and Automated Facility Management w/ Alternate WWTP and Lift Station SCADA Upgrades I. Purpose The Commission is seeking professional engineering services for the development and implementation of a new Supervisory Control and Data Acquisition (SCADA) System. II. Background The Commission wishes to replace its current telemetry and control systems that are used to operate its water systems. The current systems are proprietary in nature and have been installed over the last 25 years. The current system ties together the 4 existing sites: Water Treatment Plant (WTP), Burchard Tank, Willow Tank/Booster Station, and Carroll Tank/Well No. 8. The Commission will be installing approximately 12 Pressure Reducing Valve (PRV) stations and a Well (No. 9) at Willow Tank. These are currently in the design phase. The Commission wishes to upgrade to a nonproprietary type (open architecture) SCADA system that will encompass the entire Water utility. The new SCADA system will need to be easily expandable to allow for modifications to existing facilities as well as the addition of new facilities in the future. The telemetry master will be the Main PLC at the WTP. Additionally, the Commission would like to install a second telemetry master at the Wastewater Treatment Plant (WWTP). This will be configured to communicate to the existing SCADA computers at the plant and serve 9 lift stations. A bid alternative should be included as part of this final design effort, separately for the WWTP and the Lift Stations. Following the bid opening, the Commission will decide whether to include the WWTP and/or Lift station upgrade as part of this contract. III. Preparing and Submitting a Proposal A.
