4.1 Evolving trend of decentralized SWM

Coverage of service in these two municipalities as a result of GTZ assistance in the 1980s were not available it is believe that coverage were very high. This is seen in the numerous waste dumping site which became known as "bola" in the old communities of these two municipalities. As these municipalities expanded the waste departments did not build new site for waste. With this, the coverage continued to fall from the 1990s of about 75–50 perfect by the year 2006 according to the municipal waste directors of Berekum and Dormaa. The fall off called for the involvement of the private companies. Checks by the study revealed that the private companies formally started in Berekum and Dormaa in 2006. These municipalities were not group into zones. One company provided SWM services in the municipalities, there was no competitive bidding, and one company was given the contract to provide house to house and community collection service. This discovery confirms what Oduro-Kwarteng [39] indicated of the evolution of decentralized SWM in the country.
