Current Water Supply

MGD = million gallons per day

Where does our water come from today?

Today, water is plentiful in the RWSA raw water system, and the location and proportion of water production at each WTP is not critical.

  1. The South Fork Rivanna River Reservoir (SFRR)
    The SFRR is the largest water source for the 82,000 people using public water in the City of Charlottesville, UVA, and urban Albemarle County. SFRR water is treated near the reservoir at the South Fork Rivanna Water Treatment Plant. Currently, SFRR holds 1,115 MG, down from an original 1,700 MG.
  2. The Sugar Hollow Reservoir (SHR)
    Water for the urban system also comes from the Sugar Hollow Reservoir on the Moormans River near White Hall with a capacity of 360 MG. Up to 4 MGD is delivered via a pipeline to the Observatory Water Treatment Plant near UVA or diverted into the Ragged Mountain Reservoir.
  3. The Ragged Mountain Reservoir (RMR)
    The RMR southwest of Charlottesville is the oldest water impoundment in the system and holds 513 MG of storage. With a watershed of less than 2 square miles, the RMR requires water from the SHR to meet its water storage capacity. Water from this reservoir is treated at the Observatory Water Treatment Plant near UVA.
  4. The North Fork Rivanna River - pipeline intake.
    The northern portion of Albemarle County’s Designated Development Area is served by an intake on the North Fork Rivanna River with its own water treatment plant with a capacity of 2 MGD. Chris Greene Lake serves as a back-up supply for this plant.
  5. Other systems served by RWSA: Crozet receives water from the Beaver Creek Reservoir that is treated at a nearby plant. Scottsville is served by a local source, the Totier Creek Reservoir, and a local water treatment plant. Residents of Albemarle County who are not served by public water use groundwater from private or community wells. Well users who live in the SFRR Watershed have an influence on SFRR water and their water comes from the same hydrologic system, though they do not drink SFRR water in their homes.

How much water do we need?

Consultants working with RWSA conducted both a growth and demand analysis projecting out 20 and 50 years.

Current raw water demand averages 9-12 MGD.
By 2025 demand will rise to 14.5 MGD
By 2055 it is projected to reach 18.7 MGD.

However, we believe this demand projection is TOO HIGH. Find out why.

How much are you paying?

Water rates have risen by 70% in the last six years, yet RWSA expenses have only risen by 40%. Water usage has stayed the same or fallen. Where has the money gone?
