Construction Start Date: Fall 2020

Estimated Completion Date: Spring 2021

Project Manager: Amy Wyks 703-737-7119

Project Description:  Improvement project consisting of removal of filter media, filter bottom replacement and installation of an air‐scour system for both filters #1 and #2 at the Water Treatment Plant. These filter underdrains were originally installed in 1980, and the filter media was last replaced in 1993. This project will improve the daily treatment flow (hydraulic performance) at the Water Treatment Plant and reduce filter treatment restrictions currently encountered when the plant is operating at a high flow rate.
