Outapi’s Wastewater Ponds Produce Fodder Crops
Freeman Ngulu — Wastewater Engineering Research Group at the Institute IWAR of Technische Universität of Darmstadt is researching ways on how to increase the capacity of Outapi’s 4-step pond system to treat wastewater.
The TU Darmstadt, under the joint project EpoNa since September, is upgrading wastewater ponds to generate irrigation water, while also researching wastewater stabilization pond systems for deployment elsewhere in Africa.
In parallel with upgrading the ponds, the Hochschule Geisenheim University will carry out tests to find the most suitable low-cost irrigation technique, as well as testing different crops and cultivation methods for suitability.
According to Jochen Sinn, the project engineer, if the concept proves effective, the entire plant can be converted, and the town as operator will be able to start extensive, all year round irrigation of fodder crops with wastewater sooner rather than later.“
