Water treatment and reuse can help sustain the operations and maintenance of treatment plants through the sale of by-products (such as compost, biogas, briquettes, electricity) from the plants. This depends on the marketability of the products and the local contexts. For example, electricity sales to the public may be constrained by imposed tariffs, while biogas and briquette sales may be constrained by the location of the plant. To benefit from compost sales, suitable credit options must apply, as indicated by buying behaviour reported in Ghana.
