In Ghana, increase in population is not keeping pace with wastewater treatment plant (WTP) and out of waste treatment facilities have a total design capacity to serve about 25% of the urban 1,000,000m3/day of wastewater generated only less than 1% are treated whilst the remaining are discharged into the open drain untreated. Fewer than 10% of the existing WTP are operational (IWMI, 2009) due to chronic lack of funds to cover the costs of operation and maintenance (O&M). It is in the light of this that TriMark Aquaculture Centre, a private business entity whose activity has been incorporated into the laws of Ghana pilot a business model adapted from Waste Enterprisers Ltd, where nutrients from the wastewater is recovered for fish culture and revenue generated from sale of fish is ploughed back into O&M cost of the waste treatment plant to improve the sanitation value chain. The business is located at Chirapatre Estate in Kumasi, Ghana. The project commenced with pre-business trial from January to October, 2018.  This pilot involves only one fish production cycle for African catfish (Clarias gariepinus) to establish real baseline data on fish production and marketing value chain prior to the full scale commercialization. The main project beneficiaries will include the local community and other beneficiaries groups (fish consumers and downstream water users).The entity is in strong collaboration with Kumasi Metropolitan Assembly, International Water Management Institute (IWMI), Kwame Nkrumah Univeristy of Science and Technology (KNUST), VIA Water/Aqua for All, (The Netherlands) and Waste Enterprisers Ltd (WE) and supported with funds from the Netherlands Government. KMA are official local representative of the government and the local community. IWMI and KNUST serve as the advisory body to the business Whilst TriMark acknowledges WE as the pioneer driver of this business model. Public-private partnership approach is the key implementation strategy used by TriMark. Future replication and up-scaling of the business model is expected to provide improved and sustainable sanitation for 25% of the urban population in Ghana.
