City gat Im Louisville COLORADO - SINCE 1878 CITY COUNCIL COMMUNICATION AGENDA ITEM SUBJECT: DATE: PRESENTED BY: SUMMARY: APPROVE SOLE SOURCE PURCHASE OF INSTRUMENTATION AND ASSOCIATED SCADA SOFTWARE FOR THE SID COPELAND WATER TREATMENT PLANT, HOWARD BERRY WATER TREATMENT PLANT, AND NEW WASTEWATER TREATMENT PLANT JULY 18, 2017 KURT KOWAR, PUBLIC WORKS DIRECTOR Staff recommends approval of aggregate purchases from Hach in an amount up to $157,000 to support upgrade of laboratory equipment, laboratory equipment software and licensing, supervisory control and data acquisition integration, and an annual calibration and maintenance contract. Hach is the industry standard for laboratory testing and instrumentation equipment, and the only state approved water treatment vendor that provides the overall desired integration capability between lab equipment, instrumentation, and SCADA. The Sid Copeland (SCWTP) and Howard Berry (HBWTP) Water Treatment Plants are in need of an instrumentation upgrade. Many of the instruments relied upon for the successful treatment of water are obsolete or antiquated. In the event of failure, there would be no direct replacement or spare parts available to purchase. Additionally, technology has advanced since the purchase of the original 1990's instrumentation. Many of the instruments currently used are not as accurate, responsive, or integrated into SCADA. Replacing the antiquated equipment improves the accuracy of data collected, which improves the ability to manipulate and analyze the data to optimize the process. Further, the new equipment improves the robustness of the process through automation. Lastly, more accurate and reliable equipment allows for better efficiencies in providing safe high quality water. To enhance the instrumentation upgrades, a new software, Water Information Management Solution (WIMS) platform is included. The WIMS software provides a direct connection between the lab equipment and the SCADA system. Currently, staff uses paper bench sheets to collect data from critical points in the process. Once this data is collected, it is transferred to an excel spreadsheet for record keeping. Each month, the electronic excel spreadsheet and SCADA records are used to create various reports that are submitted by regulation to the Colorado Department of Health and Environment. The WIMS software will automate the collection of data and automate reporting which will reduce a large amount of time inefficiently spent recording data and transferring it to the appropriate place. This software will also increase the accuracy of CITY COUNCIL COMMUNICATION
