Increased drinking water consumption has created an increasing problem with disposing of or beneficially reusing drinking water treatment residuals (WTR). In 1997, the City of Durham began looking at alternative options for the disposal of approximately 1500 dry tons of WTR due to increased landfill costs. Following an economic comparison between land application, landfilling, and other options, the City of Durham awarded Synagro Southeast a contract to ratio blend and land apply WTR with biosolids. The WTR are transported to one of two Water Reclamation Facilities and blended with biosolids at approximately a 1 part WTR to 3.5 parts biosolids ratio. This ratio results in uniform blending of the annual volumes of both byproducts. The current blending program has been in operation since 1998 with all the blended material being applied to agriculture land. The blended material has not affected the farmers production practices and returns approximately 2 dry tons of soil to the fields annually. Along with the farmers, the City of Durham benefits from a beneficial reuse program that is the most economical WTR disposal option.
