Directo , -ter Resourc- : Department

The City of Greensboro's Lake Townsend Water Treatment Plant is a
conventional surface water treatment facility permitted to treat (filter) 30 million
gallons of water per day (MGD). The water produced by the facility meets all
applicable State and Federal standards. Current average daily production at the
facility is 21 MGD.
All filter backwash and sedimentation wastewater from the facility flows to a
settling lagoon on the plant site. Filter backwash flow is intermittent based on
plant treatment rate and raw water quality conditions. Sedimentation wastewater
flow is relatively constant with automated equipment removing dilute sludge
(approximately 1 % solids) to maintain full sedimentation basin volume.
As wastewater flows through the settling lagoon, solids removed during the
treatment process (consisting primarily of Aluminum Hydroxide precipitate and
the captured turbidity causing materials from the untreated raw water) settle to
the bottom of the lagoon leaving a clear supernatant which meets the NPDES
permit requirements.
Sludge solids generated from the treatment process average approximately
1,100 dry tons per year. At 12 to 15 month intervals, the city contracts a private
sludge management firm to dredge and dewater the solids from the lagoon. The
most recent cleaning was completed during August -September of 2005 by
American Process Group of Alberta, Canada. All solids removed from the lagoon
are used as either fill or cap admixture at the city's White Street Landfill off of
Highway 29.
