Research has indicated that, irrigation schemes which are established purposely for irrigation of crops turn out to be a multipurpose facility rather than their intended purpose. Some of these uses turn to conflict with the primary purpose there by, sometimes reducing the quality and/ or quantity of the water downstream. Studies in Kumasi and Accra on the quality of urban and peri-urban waters used for irrigation of vegetables revealed that these urban waters were highly polluted especially with faecal coliforms.
