Projectdata
Under this assignment, the Independent Sewerage System Performance Assessment being part of the Lusaka Sanitation Programme, a performance evaluation of the sewer system was conducted, and a definition of potential rectifying interventions was proposed. Moreover, it was required to identificate the following issues:
- Technical, commercial, environmental and social risks for the investments, the operation and maintenance as well as the beneficiaries/population affected,
- Mitigation measures required to warrant full utilization of the overall system and to secure sustainable O&M of the overall system including corresponding cost estimates for investments and consultancy services,
- Gap analysis of LWSC and their current technical, commercial, and financial O&M capacities for these respective facilities and definition of risk mitigation and training measures including cost estimates.
