In May of 1959, the Loudoun County Board of Supervisors created Loudoun County Sanitation Authority, doing business as Loudoun Water, by a resolution, through the Water and Waste Authorities Act, for the sole purpose of providing water and wastewater service to residents of the unincorporated areas of Loudoun County. These areas are generally the communities east of Route 15 and some communities s
