embracing change and seizing opportunities to create a
more robust and sustainable water system. Situated in the
fast-growing suburbs of Washington DC, Loudoun Water
provides chloraminated drinking water to over 65,000
households through a network of over 1,200 miles of pipes
and 7 tanks.
Loudoun Water has made it their mission to improve
operational efficiency of their drinking water system. For a
chloraminated water system, that means getting control of
nitrification. Loudoun Water used to be a simple secondary
system, receiving free chlorine drinking water from the City
of Fairfax, then chloraminated water from neighboring
Fairfax County for a blended system. However, with the
growth in their community, Loudoun County continued to
expand their capabilities, building additional transmission
mains and storage capacity that culminated with the
construction of the Dulles South tanks, a pair of 3-MG fluted
composite tanks to serve the southern portion of its system.
