The application of sewage sludge to land returns essential nutrients to the soil, adds organic matter, and can improve the tillabilty and moisture retention capability of the soil. A sewage sludge utilization permit is required by the Maryland Department of Environment for any person who treats, composts, transports, stores, distributes, applies to land, incinerates, conducts innovative or research projects or disposes of sewage sludge or septage (effluent from septic tanks) in Maryland. Sewage sludge (also known as biosolids) is not sewage. It is one of the final products of the treatment of sewage at a wastewater treatment plant. After treatment to break down the organic matter and destroy disease causing organisms, the remaining fine particles ultimately become sewage sludge.
