The KLRWS owns and operates a 10 MGD water treatment plant located in Vance County which utilizes Kerr Lake as a source of supply. As a part of the routine water treatment process, residuals are generated by the KLRWS from two different treatment processes; gravity sedimentation and media filtration. A series ofgravity sedimentation basins are used to settle suspended solids from drinking water that has been conditioned using aluminum sulfate (alum) and polymer. The solid contaminants collect on the bottom of the basin and are routinely removed by a mechanical collection system. This waste stream is referred to as sedimentation blowdown residuals. Additionally, these basins are drained for cleaning and inspection on a periodic basis. The second waste stream generated by water treatment is a result offilter cleaning orbackwashing. During this process the filter flow is reversed to flush out solids and other contaminants that are filtered from the settled water onto the anthracite and sand media. Chlorinated water is utilized for this backwashing process and the waste stream is referred to as spent filter backwash (SFBW). The KLRWS is currently upgrading the solids handling facilities at the water treatment plant to eliminate restrictions in plant capacity due to these processes. The plant upgrade includes addition of two 80 ft diameter batch thickening basins for handling and treatment ofresiduals generated as aby product ofwater treatment. With the addition of the two new thickening basins the KLRWS now has the capability of treating increased volumes of both sedimentation blowdown residuals and SFBW. Each of these residual streams are combined for treatment in the gravity thickeners. The thickeners were designed to allowthe addition of polymer into the combined residual streams, if necessary, to aid in sedimentation. The thickeners operate in a batch mode meaning that one basin is filled to capacity after which the suspended solids are allowed to settle for a period of time before stream discharge of the thickener decant to Kerr Lake. Under peak water demand conditions the total volume discharged to Kerr Lake could be as high 675,000 gpd. The settled solids accumulate in the bottom of the thickener over time and periodically are removed by aturn-key contractor and hauled off -site for land application disposal under separatepermit(s). The facility will maintain the ability to utilize the existing residuals handling facilities which include astorage and settling basin and sand drying beds which are scheduled for improvements in the future. Monitoring of the total discharge volume and water quality from the facilities is performed routinely by KLRWS staff to determine that the decant stream meets NPDES permit limits prior to discharge to Kerr Lake. The facility generates no other surface water discharges.
