Geotechnical properties of sewage sludge

Abstract

In the UK ever-increasing volumes of sewage sludge are being deposited in engineered landfills. To design these facilities properly it is necessary to quantify the engineering behaviour and properties of this sludge, which is not a true geotechnical material. Although sewage sludge has a very open structure it exhibits very low permeability and attempts have been made to use additives to improve is drainage characteristics.
