STAFF: Kyle Flanagan, Deputy Director of Public Works
BACKGROUND:
TCEQ requires Public Drinking Water Systems (PWS) to record daily flow metering of water use to report on daily, monthly, and annual water usage to the Texas Water Development Board. Recently, the Town was audited by the TCEQ and found to be in violation for not conducting daily readings on both influent meters at the Pump Station on SH 377 on weekends and holidays. An ILA was established with Roanoke to read these meters on weekends and holidays to rectify this issue.
Recently both influent meters to the Towns Distribution System have broken and are outdated and need to be replaced. These meters are tied to the SCADA (Supervisory Control and Data Acquisition) system to control the rate of influent flow.
Title 30 Environmental Quality, Part 1 Texas Commission on Environmental Quality, Chapter 290 Public Drinking Water, Subchapter D Rules and Regulations for Public Water Systems. Rule §290.46 (II) Systems that serve 250 or more connections or serve 750 or more people shall maintain a record of the amount of water distributed each day.
DISCUSSION:
the Both influent meters are now broken. Ground Storage Tank 1’s meter (GSR 1) broke around September 3rd and now the GSR 2 meter is not recording accurately. This is creating issues for the Town of Westlake’s wholesale water provider, The City of Fort Worth.
The influent meters are utilized to regulate the influent flow into the Ground Storage Tanks which provide storage capacity to the Towns Drinking Water System. Fort Worth allows Westlake to draw a combined 5.7 MGD or approximately 4,000gpm through the existing wholesale meter. With the meters broken on the Tanks the Town is currently drawing water in at a rate of 9.36 MGD or 6,500gpm. This rate of flow can damage the wholesale meter and will also result in higher max hour daily charges costing significantly more in the annual penalty charges on the Fort Worth water bills.
As an added benefit of replacement of these meters to more technologically advanced meter will allow for future programing in the SCADA system to read and record via time stamp daily influent flow of water usage. This will sunset the need for Roanoke to read these the meters on weekends and holidays.
FISCAL IMPACT:
Amount not to exceed $23,164
