The Rivanna Pump Station is a booster station operated by the Rivanna Water and Sewer Authority that supplies the Moores Creek Wastewater Treatment Plant with untreated sewage via a 2,600 long 36-inch diameter force main. The station was built between 1979 and 1981, and has a capacity of 24.5 million gallons a day, as of 2011.

Location

The pump is located at the corner of Chesapeake Avenue and Riverside Avenue in Charlottesville's Woolen Mills neighborhood[1].


Expansion

The RWSA is planning to expand the station's peak capacity to 53 million gallons a day as part of a collaborative effort with the City of Charlottesville and Albemarle County to reduce the amount of stormwater that infiltrates the regional sewer system. [2] However, residents of the Woolen Mills' neighborhood are concerned the expansion will increase odors in their community. [1] The firm Hazen and Sawyer has been hired to serve as the engineering consultant. [3]

Four sites have been under consideration for the upgraded pump station and each has a preliminary “concept level” cost estimate:

  • Concept A ($25 million): upgrade the pump station at its existing location
  • Concept B ($29 million): up the Rivanna River in Riverview Park
  • Concept C ($37 million): downstream near the old Woolen Mill and Moores Creek
  • Concept D ($34 million): across the Rivanna River below State Farm Insurance[3]

The Virginia Department of Environmental Quality has issued a consent order mandating that an option be selected by December 31, 2011. [4]

City Council has expressed its opposition to Concept A and its preference for Concept D [5]. The ACSA and the Board of Supervisors want the RWSA to leave Option A on the table. [6] [7]

However, at the April 2011 meeting of the RWSA, the board of directors voted 4-1 to direct Hazen and Sawyer to further evaluate Option C after representatives from State Farm Insurance indicated they plan to expand parking at their facility in the option D location. [8]

At the May 2011 meeting of the RWSA, Hazen and Sawyer was directed to study options A, D and a hybrid E option which would involve driving a tunnel to the wastewater treatment plant. [9] Cost estimates will be available in the fall.
