“Between 2010 and 2040 the population served by Fairfax Water, including both retail and wholesale areas, will increase by over 650,000 residents and nearly 550,000 employees working in the area,” according to Fairfax Water’s Chairman Philip Allin, chairman of Fairfax Water. So Fairfax Water and Vulcan Materials Company recently signed an agreement to convert Vulcan’s quarry, in Lorton, to a Fairfax Water reservoir.
When the conversion is complete the reservoir will be capable of holding up to 17 billion gallons of water. The first phase of the project will begin in 2035, when Vulcan ends operations in the northern part of the quarry. The remainder of the quarry will be transferred in 2085.
So, it’s unlikely that very many of us will drink water from the new reservoir.
The region also uses two reservoirs for daily use and as two backup supplies during droughts when the Potomac River stream flow is low. The new reservoir will provide significant additional storage in case we experience a regional drought.
