LCRA has recently installed new valves in the water system to address pressure problems in the Glenlake Water System. The next step is to install individual PRVs for those residents located at lower elevations. After installation of these individual PRVs, the overall pressure in the system will be raised. As a result, residents at higher elevations in the system should no longer experience low pressure problems that have persisted since the system was built. As mentioned earlier, residents at lower elevations will need a pressure reducing valve installed to lower the pressure of water entering their home.
Individual Pressure Reducing Valve Update
Technical Documents and Exhibits
- Problem Statement & Solution
- Figure 1 illustrates the range in elevations and the resulting pressures along some of the lowest and highest areas around the system.
- Figure 2 is a contour map of the system, which illustrates the existing 80 psi contour elevation (purple line) and the 80 psi elevation (red line) that will result from the completion of the improvements explained below. Customers can refer to Figure 2 to determine which contour elevation their property falls within.

Previous Engineering Reports
The reports below were developed while LCRA was contemplating construction of additional storage to address the pressure problems. LCRA has signed an agreement with the River Place MUD to allow the Glenlake Water System to utilize the MUD's elevated storage tank. As a result, the LCRA is not building any new storage tanks in the Glenlake system.
