Enhancing trade effluent management practices in Lusaka
The assignment supports the GIZ NEWZA programme by strengthening industrial wastewater (trade‑effluent) management in Lusaka. The objective of the project is to establish a risk‑based, routine operating model that protects sewers, treatment plants, and receiving waters while providing a predictable compliance framework for industry. The scope covers:
- updating the register of industrial and commercial dischargers and mapping them to the sewer catchments and treatment works;
- designing and institutionalising a monitoring regime - inspection, sampling, transport, analysis, and reporting - aligned with available laboratory capacity;
- standardising procedures for pre‑treatment at source and compliance escalation;
- integrating data flows into the utility’s management information environment for timely decisions.
Deliverables include a validated discharger inventory with risk classification, standard operating procedures (SOPs) for field and laboratory routines (including chain‑of‑custody and QA/QC), a pragmatic sampling and analysis plan, technical guidance for priority sectors, and a results dashboard that links samples to actions. Implementation is undertaken with Lusaka Water Supply and Sanitation Company (LWSC) and municipal counterparts, with targeted coaching to embed practices beyond project close. The project prioritises proportionality (focus on high‑risk dischargers), traceability (evidence from field to lab to decision), and enforceability (clear roles, timelines, and records that support stepwise compliance).
