Water Conservation-Occoquan

The UOSA sewage treatment plant in Centerville, is unique in that the highly treated sewage output supplies roughly 20% of the inflow into the Occoquan Reservoir, which Fairfax Water uptakes and sends as drinking water to many homes   This treated sewage effluent is actually far cleaner than the stream sources that flow into the Occoquan Reservoir.
