City to Install Pressure Regulating Valves in Coming Months

Five automatic Pressure Regulating Valves (PRVs) will be installed in the City in the coming months. The valves will be installed along the borders of high and low pressure planes of the water distribution system to automatically regulate water sharing between the two planes using pre-determined pressure settings. Simply put, the valves will act as a bridge to ensure an automatic, constant flow of water between the high and low water pressure planes.

The installation of the pressure regulating valves, which is part of the City’s Southlake 2030 Water Master Plan, has two primary goals:

  • Keeping the water pressure constant during peak usage periods or when water pressure drops below a pre-set level in either plane.
  • Ensuring that the water distribution system can respond to fire emergencies during peak usage periods with little to no disruptions.

The installation of the PRVs will also allow the City’s water system personnel to better monitor any changes to the water pressure and to the valves themselves. Because these new valves are automatic and respond to pre-determined pressure settings, the City’s remote water monitoring system (SCADA) will keep tabs on the valves and allow water personnel to address problems with greater efficiency.

Since the installation of these valves will affect five locations around the City, it’s important to note that impact to citizens during the installation should be minimal. However, residents around the construction zones need to be aware of a few things:

  • Although any traffic impact will be minimal, it will vary from one location to the next and will be dependent on how much room the contractor has to maneuver equipment within the right of way. Please be aware when driving around the installation areas.
  • At least one water shutdown (possibly two) will occur for each installation site. Depending on the location of existing valves, a small number of homes MAY be affected. However, the shutdowns will be planned well in advance and affected residents will be notified of the duration of the shutdown in each case.
