Cumberland Wastewater Treatment Plant Heat Drying Facility. Cumberland, Maryland.

The need for a more flexible method of disposal and beneficial reuse for biosolids, led to the selection of heat drying technology, due to its reliability and flexibility.

WR&A evaluated existing plant solids production data to quantify long-term sludge projections and characterize the solids and project future sludge quantities for processing through the heat drying facility. Subsequently, a comprehensive RFP was prepared for use in the evaluation of responders and selection of a privatization contractor to design/build/operate a heat drying facility. WR&A prepared the contract documents for siting the heat drying facility, providing the interface with the plant solids handling facilities and implementing construction of the heat drying facilities in conjunction with the ENR upgrades, also designed by WR&A.

WR&A developed detailed contractual requirements, enabling the construction for the heat drying facility to be incorporated in the ENR construction contract. Both projects were constructed simultaneously on a rather restricted site, which required substantial coordination to avoid interferences.
