Guidelines for the Utilisation and Disposal of Wastewater Sludge

Traditional practices related to wastewater sludge management include dedicated land disposal, waste piling, landfill disposal and, to a lesser degree, use in agricultural practices. However, due to varying reasons, on-site land disposal and waste piling have become the standard management options for many wastewater treatment plants in South Africa today. With sludge production increasing on a daily basis, it has however become apparent that current practices are unsustainable with sludge management becoming a problem for many municipalities in South Africa. Innovative solutions need to be sought to create opportunities that provide a wide spectrum of options to the management of wastewater sludge. This guideline aims to provide options and opportunities for this innovation and to encourage the beneficial use of wastewater sludge. Where wastewater sludge cannot be used as a resource, the guidelines also provide for its disposal in a responsible manner.
