industrial effluent discharge mapping

There are many problems associated with the discharge of wastewater from industries into water bodies. These problems can lead to environmental pollution which in turn leads to a variety of diseases, and a decline in public health for both people and marine organisms. With the awareness of this issue, the External Processing Zones Authority (EPZA) in partnership with Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) in Tanzania contracted OMDTZ to lead the Effluent Discharge Mapping project and conduct a pilot project in the EPZA industrial zone in Dar es Salaam aiming to acquire the geographic locations of the industries and develop an effluent discharge database management system (DBMS) from this spatial data. 

The data generated further acted as a guide for environmental control and useful for managing wastewater and boreholes’ existence. This was obtained from the knowledge of registered and non-registered boreholes and those in operation or not. This data not only helped the EPZA and GIZ in controlling the effluent discharges but acted as a pilot for a broader scope of managing industrial wastewater treatment and discharge in Tanzania discharge in Tanzania. The data can also be used by the National Environment Management Council (NEMC) in Tanzania. 

Timeline

The project was implemented in September 2019 to January 2020.

Funding

The project was Funded by GIZ (Deutsche Gesellschaft für Internationale Zusammenarbeit) –a Germany development agency that provides services in the field of international development cooperation.

Impact of the Project

  • Data will support in managing industrial wastewater
  • Making follow-ups on discharge permits and an understanding of how many industries have valid permits
  • Overall environmental managements around industrial zones
