Southern Water Tank

The Town of Round Hill is currently applying for a Loudoun County Special Exception and a Commission Permit to build a Southern Water Tank in the future.

SPEX-2018-0010 is for a Special Exception Application to allow the construction of a 500,000-gallon elevated water tank in the AR-1 Zoning District (as well as Commission Permit CMPT-2018-0002). CMPT-2018-0003 is for a Commission Permit to allow telecommunications antennae (on the water tank) in the AR-1 Zoning District.

The property is identified as Loudoun County Tax Map Number /43/A/2////22B and PIN Number 586-40-5980, with access from Yatton Road via an easement through 18115 Ridgewood Place, Round Hill, Virginia 20141.


The public hearing before the Loudoun County Planning Commission is on November 27, 2018 at 6:00 pm, to be held at Loudoun County Government Center, 1 Harrison Street, S.E., First Floor, Leesburg, VA

Frequently Asked Questions: 

1.       Need for the Tank:  System reliability and redundancy, increased available fire flows and system pressures during high demand periods, improved system operation and flexibility, and to allow necessary maintenance activities on the existing Evening Star Tank.

2.       Current Demands vs. Future Demands:  The primary purpose of the tank is to address needs for the current system for the reasons noted above.

3.       Why Was This Site Selected?:  In short – a combination of location, topography, and availability.  In order to achieve the functional needs as noted above, the new tank must be located at the same hydraulic grade as the existing Evening Star Tank, therefore relatively higher ground elevation is important.  The location must be in fairly close proximity to the existing distribution piping system, and the southern area of the system was targeted to address specific reliability concerns and because this area has a greater need in terms of available fire flows.

4.      Other Strategic Planning Points to Consider:

  • The tank was part of the original planning process for Round Hill Utility System. The site was chosen because of the elevation and compatibility with our existing utility system
  • The tank project is part of the 2017 Town Comprehensive Plan, FY2018-2023 Town CIP and FY2019 Town Budget
  • This will be our second major storage tank and is critically needed to provide both storage and more importantly needed gravity pressure to the south side of our system.
  • The tank is critical for redundancy and we are one of a few communities in this region with only one major tank. If we were to lose service or operations of our existing tank, it would  have a major impact on our system.
  • The proposed tank is set at the same elevation of our existing tank for equalization reasons. They will maintain the same levels by transferring back and forth.
  • The current location was selected for topography, developer dedication of the lot and availability to existing lines in the Bluffs.
  • Moving the tank to another location would be extremely costly due to land acquisition, additional cost to build a higher tower and easements/construction needed to access our existing water lines.
