Sludge Treatment and Disposal Programme - Accompanying Measures
This project, co-financed by KfW Development Bank includes the rehabilitation and extension of the treatment of sludge from the existing treatment plants (WWTPs) in Tunisia. Accompanying measures are also implemented to ensure the proper management of the newly constructed facilities. The implementation will be carried out by the National Sanitation Utility of Tunisia (ONAS).
Dorsch Impact's main objective is to support and assist the ONAS in implementing an investment measures programme for the management and valorisation of sludge, thus contributing directly to access adequate and equitable sanitation, including the safe disposal or reuse of the treated excreta and sludge.
