The management of wastewater solids has always been an issue of concern for waste-
water treatment plants (WWTPs), especially because these costs substantially con-
tribute to the overall costs of operating and maintaining a WWTP. Moreover, many
utilities find it difficult to track all of the costs associated with wastewater solids
management. Representative utility-wide costs from which to benchmark operations
are difficult to find.
