Tours

While you are in Washington, DC for the conference, we would like to invite you to take advantage of a unique opportunity — register for a tour of two local water reclamation facilities on either Sunday or Wednesday afternoon. All tours will depart from the main entrance of the hotel. Please check the schedule of events as the tours may conflict with other scheduled conference activities.

Tour #1: Technical Tour of Two Water Reclamation Facilities: the Broad Run WRF and the Upper Occoquan Service Authority WRF

Sunday, September 12
9:00 a.m. - 4:00 p.m. 
Fee:  $55 (includes a box lunch)
Limited to 40 people

This day-long tour will take attendees to two premier water reclamation facilities in the Washington, DC area. The first stop will be at Loudoun Water's new 11 mgd Broad Run Water Reclamation Facility located in Ashburn, VA. After touring this facility, the group will have lunch and then travel to the Upper Occoquan Service Authority (UOSA) 54 mgd Water Reclamation Facility located in Centreville. VA.  At each stop, attendees will receive an overview of the technical, water quality, and regulatory drivers for each facility as well as a facility tour. The tours are being conducted in cooperation with the Virginia Department of Environmental Quality. The VDEQ Coordinator for Water Reuse, Valerie Rourke, will be in attendance to answer questions about Virginia's planning and vision for water reuse. Each facility is described below.

The 11 mgd Broad Run WRF is a community-friendly, campus based facility that was designed to deliver a message of water stewardship. The plant tour will include major processes, the water reuse system, and Loudoun Water's public education center — the Aquiary. The facility uses membrane bioreactor (MBR) technology followed by activated carbon treatment and ultraviolet (UV) disinfection. The facility is designed with biological and chemical nutrient removal to meet extremely stringent nitrogen and phosphorus permit limits. The reclaimed water meets the most stringent Virginia water reuse standards and is used for local nonpotable water reuse applications.
The UOSA 54 mgd WRF is the largest, most mature, surface water, indirect potable reuse facility of its kind in the world.  UOSA has successfully supplemented the safe yield of the Occoquan Reservoir, a principal drinking water supply for nearly 1.5 million northern Virginians, for more than three decades. The high quality water, which meets the most stringent Virginia water reuse standards, is also used for a wide range of onsite nonpotable reclaimed water uses. The UOSA plant employs several treatment processes to cost effectively produce high quality water including conventional preliminary and primary treatment, secondary treatment using biological nitrogen removal, lime clarification, two stage recarbonation with intermediate settling, multimedia filtration, granular activated carbon (GAC) adsorption, disinfection, and dechlorination.
