title: Development of the South African wastewater sludge guidelines.
abstract: The new South African Wastewater Sludge Guideline Series will replace the document entitled: "Permissible Utilisation and Disposal of Sewage Sludge, Edition 1, 1997" which deals with application of sewage sludge to land. The new guideline series will be published as 5 volumes: Volume 1: Management Options for the Use or Disposal of Wastewater Sludge, Volume 2: Requirements for the agricultural use of wastewater sludge, Volume 3: Requirements for the on site and off-site disposal of wastewater sludge, Volume 4: Requirements for the use of wastewater sludge in the production of commercial products, Volume 5: Requirements for the incineration of wastewater sludge, We envisage that Volumes 1 and 2 will be published at the time of the conference and that work has begun on Volume 3, 4 and 5. The paper aims to communicate the major differences between the previous sludge guidelines and these new sludge guideline series. For example, the paper details the new wastewater sludge classification system and the requirements for the characterisation of the sludge for classification purposes. The paper will also explain the approach followed in the development of Volume 1 and 2 and will elaborate on the proposed approach for Volumes 3, 4 and 5.
