GIZ has been commissioned to implement the project Nexus Energy and Water Program for Zambia (NEWZA) previously called "Strengthening Institutions for Sustainable Water Supply and Sanitation Services in Zambia (SIWAS)" on behalf of the German Federal Ministry for Economic Cooperation and Development (BMZ). NEWZA is a multi-donor action jointly co-financed by the European Union, BMZ and UNICEF. However, the trade effluent activities under NEWZA are funded only by BMZ as part of the German Development Cooperation program.

Based on activities in the previous project phase, SIWAS, now called GIZ-NEWZA includes interventions for improved management of industrial wastewater in Lusaka. The focus is to provide technical assistance to Lusaka Water Supply and Sanitation Company (LWSC) and other stakeholders to strengthen their capacities in trade effluent monitoring, regulation, and enforcement. This is to ensure that adequate measures will be in place to safeguard wastewater treatment plants from trade effluent discharged into public sewers. Interventions are closely linked to the investment project "Ecological Urban Development Lusaka", which is implemented through the German Development B
ank KfW, through which two wastewater treatment plants for Lusaka are being financed under the Lusaka Sanitation Program.

A Contractor is required to provide technical assistance to enhance trade effluent management practices in Lusaka. A team of experts with national and international experience shall be provided by the Contractor for this purpose. Services of the Contractor include capacity development measures to strengthen the capacities of LWSC and other key stakeholders to ensure the long-term functionality of the wastewater treatment plants by minimising to acceptable levels and/or avoiding the influence of substances from trade effluent that impair treatment processes and cause structural damage. Services of the Contractor shall be delivered in close collaboration project partners and in coordination with the GIZ project team in Zambia.
