The Safe Drinking Water Act is the federal law that protects public drinking water supplies throughout the nation. The City, also referred to as a Public Water System (PWS) by the Texas Commission on Environmental Quality (TCEQ), is required to comply with Texas requirements for monitoring, maintaining, and reporting drinking water disinfectant levels to ensure public health. Since 1947, Public Water Systems in Texas are required to maintain minimum drinking water disinfectant levels in order to protect public health throughout their distribution systems. Since 2000, Public Water Systems must collect and sample disinfectant levels at least one time per day each day throughout the distribution system to obtain a citywide sampling of the quality of the water. 4 Chlorine Analyzers with Prime Controls Southlake’s Drinking Water Quality Program: Daily chlorine disinfectant residual sampling Weekly bacteriological (Bac-T) testing Quarterly disinfection byproduct testing Yearly lead and copper testing Weekly Nitrification Action Plan monitoring (New) Monochloramine Ammonia Nitrate Nitrite Temperature pH level Southlake’s Drinking Water Quality Program includes: Daily chlorine disinfectant residual sampling Weekly bacteriological (Bac-T) testing Quarterly disinfection byproduct testing Yearly lead and copper testing and Weekly Nitrification Action Plan monitoring (New Regulatory Requirement that started in 2016) Monochloramine Ammonia Nitrate Nitrite Temperature pH level 5 Chlorine Analyzers with Prime Controls Public Works Water Division personnel: Collect all of the daily chlorine disinfectant measurements daily 12 locations Fort Worth Stations - Caylor and Alta Vista effluent Entry points into the City at the pump stations and their discharge Elevated storage tanks 2 of the 30 routine bacteriological (Bac-T) sample sites 300+ Chlorine samples per month Dove Tower Miron Tower Public Works Water Division personnel currently collect all of this data on a daily basis by driving to each of the sampling sites. Total chlorine residual disinfectant levels are measured daily at 12 locations including the Caylor and Alta Vista effluent (Fort Worth's stations), entry points into the City at the pump stations and their discharge, all elevated water storage tanks, and 2 of the 30 routine bacteriological (Bac-T) sampling sites (these locations vary daily). On average, Water Division personnel collect 300+ total chlorine samples per month by hand as part of the City’s Water Quality Program. 6 Chlorine Analyzers with Prime Controls 8 Chlorine Analyzers: Supplement the disinfectant residual data collected daily Include the critical software integration into SCADA system Provide real time drinking water disinfectant residual data (5 min intervals) Increased “leading indicator” data 8 Locations: Booster Stations – Pump station 1 & 2 Wholesale provider – Alta Vista and Caylor Elevated Storage Tanks – Florence EST., Dove EST., Miron EST., Bicentennial EST. The eight (8) chlorine analyzers will supplement the disinfectant residual data that is collected by Water Division personnel on a daily basis as required by State regulatory requirements and the Texas Commission on Environmental Quality (TCEQ). This purchase includes the critical software integration of the chlorine analyzers into the City’s Supervisory Control and Data Acquisition (SCADA) system in order to have real-time drinking water disinfectant residual data specifically from within the City’s drinking water storage facilities. Through the integration, the analyzers will be able to collect and report back total chlorine residual disinfectant levels in 5 minute intervals; Thereby increasing the City's total chlorine "leading indicator" data from the storage facilities from 1 per day to 1 every 5 minutes or 288 data points per storage facility per day. Please note that this does not eliminate the need for data collection at other locations throughout the City. 7 Chlorine Analyzers with Prime Controls Funding available: FY 2017 Water Division Operating Budget Texas Local Government Code: Chapter 252 Section 252.022 Funding for this item was approved by City Council in the FY 2017 Water Division Operating budget in an amount of $92,440.
