Engagement knows no boundaries

We all live in the same environment. We are only able to maintain it together.

AWAS delivers environmental technology for Ghana


The resource of water is becoming increasingly scarce in Ghana. The causes are growth of population, urbanization and expansion of irrigated agriculture. At the same time water pollution caused by industrialization increases. For the Ghanaian water supply open water reservoirs are often used which are fed by industrial wastewater as well. Sewage systems are rarely available. Water treatment in the outdated municipal facilities constitutes a major problem.

60.000 litres per day

This is where the AWAS-project starts: We installed an exemplary system for wastewater treatment at the Ghanaian producer for edible oil Ghana Nuts Limited (GNL). It treats the daily 60.000 litres of wastewater and recycles most of it back into the production process. GNL-employees were trained in operation and maintenance of the system in order to use it independently in the future. In addition, information events about water management are planned. As part of this commitment, AWAS built a public drinking fountain in the immediate vicinity of the plant, which will provide, among others, a hospital which is still under construction. To prevent bacterial contamination of the well water, a biological light system is integrated.

Transfer of knowledge

The aim of the project is to promote knowledge transfer and exchanges between enterprises, institutions, universities and the population in Ghana on water management and to raise awareness for it. The State Environmental Protection Agency of Ghana receives assistance for new standards of water quality. AWAS uses this demonstration plant to gain reliable market data and to show itself as a professional partner for water and wastewater treatment in the African market.


"We are a producer of soya oil and shea-butter. We produce approximately 30 tons of soya oil and 70 tons of shea-butter every day. For the production of the oil we need a lot of fresh water. Simultaneously a big amount of waste water arises. In the past we had some difficulties with environment agencies because we were not able to clean our waste water correctly. Through a public private partnership with the German company AWAS we built a new waste water treatment plant. Since we have built this plant, we protect the environment. At the same time we produce cost-effective, because we return the cleaned water back into the production process."
