Fairfax Water Announces System Improvements for Customers Served by the University Tank

We are pleased to announce that much-needed system improvements will be implemented later this year for customers served by the University Tank. To improve service to customers, Fairfax Water is replacing the storage tank located on the Fairfax campus of George Mason University (GMU).

If you are a residential customer and received a letter from Fairfax Water regarding the need for a PRV, click here. If you live within the zone but did not receive a letter, you do not need a PRV.

Note: This is a rendering of the tank.

Why was a new tank necessary? 

The tank controls water pressure on the campus as well as surrounding areas in Fairfax County and the City of Fairfax. These areas currently experience delivery pressures that are lower than those typically experienced elsewhere in Fairfax Water’s system. The replacement tank is taller than the previous tank, which will increase delivery pressures to customers in the areas shown on the map below. Changes to the style of the tank also ensure water quality will be maintained.

Will my home be impacted? 

Many customers within the University Tank pressure zone will experience either a welcome increase in pressure or they may not notice a change in the pressure at all. To determine if your home is within the University Tank pressure zone, type your address in the search bar in the upper right-hand corner of the map below. Please note: Customers who did not receive a PRV letter and live within the blue area in the map below are not expected to see pressure over 80 PSI, therefore they do not need a PRV.

I received a letter about my home possibly needing a PRV. What is a PRV and why would my home need one?

In some cases, customers in the area may experience a higher than desired pressure or greater than 80 pounds per square inch (PSI).  This may result in the need for a Pressure Reducing Valve (PRV).   

We have identified those customers who may experience water pressure greater than 80 PSI and mailed letters to them containing further information.  If you have received one of these letters, please click here for more information.   

Customers who did not receive the letter and live within the blue area in the map above are not expected to see pressure over 80 PSI.
