SUBJECT:      QUARTERLY UPDATE

DATE:         OCTOBER 2020


This quarterly update is to provide general information on the drinking water, wastewater and solid
waste programs managed by the Rivanna Authorities, as follows:

   1. The production of drinking water for the Urban area (Charlottesville and adjacent developed
      areas of Albemarle) averaged 10.17 million gallons per day (mgd) in September 2020, which
      was slightly below the five-year average for September (10.78 mgd), as shown by the
      following graph:
2. Urban wastewater flow for September 2020 (10.10 mgd), including flows from Crozet, was
   below the five-year average for September (10.35 mgd), as shown by the following graph:




3. A general overview of significant current and upcoming Capital Improvement projects
   includes:

   A. Water Treatment Plant Improvements
      Scope: Replace equipment which has reached end-of-service life at the South Rivanna
      and Observatory Water Treatment Plants. Increase water treatment capacity from 7.7 to
      10 million gallons per day at the Observatory Water Treatment Plant.
      Completion:               2020 - 2023
      Cost:                     $43 million

   B. South Rivanna Dam – Gate Repairs
      Scope: Repair original gates installed in 1966. These gates are located near the bottom
      of the dam, and are used to release water from the reservoir.
      Completion:               December 2020
      Cost:                     $900,000

   C. Sugar Hollow Dam – Gate Replacement and Intake Tower Repairs
      Scope: Replace the inflatable rubber device that sits on top of the concrete dam and
      regulates the normal water level in the reservoir. The gate is over 20 years old, and has
      reached the end of its service life. Concrete repairs will be made on the intake tower.
      Completion:                Fall 2021
      Cost:                      $1.7 million


                                             2
   D. South Rivanna to Ragged Mountain Reservoir Pipeline Easements
      Scope: Determine alignment and acquire easements for a pipeline and pumping station to
      transfer raw (untreated) water between the South Rivanna Reservoir and the Ragged
      Mountain Reservoir, as required by the Community Water Supply plan. The Board of
      Directors of the Albemarle County Service Authority renewed its endorsement to complete
      this water supply project from 2027 – 2033. This endorsement is consistent with the
      project schedule in our CIP. Progress continues in our efforts to acquire the 9.5 miles of
      easements and agreements (with VDOT) for this 36” water line. City Council approved
      easements on four properties located near Ragged Mtn reservoir on September 8th.
      Easements have been obtained from 8 private owners, and negotiations continue with the
      remaining 4 private owners. We have completed our process to notify VDOT about our
      planned locations in the street right-of-ways.     Discussions continue for remaining
      easements with the UVA Foundation and the County School Board.
      Completion:               2021
      Cost:                     $2.3 million

   E. Ragged Mountain Reservoir to Observatory Water Treatment Plant Raw Water Line and
      Raw Water Pump Station
       Scope: Replace two 18-inch cast iron raw water pipes, which have been in service for
       more than 70 and 110 years, respectively. Replace the existing Stadium Road and Royal
       raw water pump stations, which have exceeded their service lives or will require
       significant upgrades, to support the Observatory Water Treatment Plant expansion.
       Completion:                2023 - 2026
       Cost:                      $18 million

   F. Upper Schenks Branch Wastewater Piping Replacement, Phase II
      Scope: Replace sewer piping installed in the mid 1950’s in conjunction with the City’s
      sewer upgrade program to increase system capacity. The new underground piping would
      be located near McIntire Road.
      Completion:               TBD
      Cost:                     $4 million

   G. Urban Finished Water Master Plan
      Scope: Identify drinking water infrastructure improvements, including distribution
      system piping and storage tanks, to provide capacity and pressure in the urban water
      system.
      Completion:              January 2021
      Cost:                    $253,000
