Water treatment plants (WTP) produce copious quantities of solid waste in the form of sludge that is deteriorating water resources, agriculture lands and human health. It should be discarded properly but a grave issue is finding ecological solution for its ultimate disposal. This study will provide an idea of incorporating sludge into soil-cement bricks that are used for construction providing dual benefits: reducing amounts of sludge and introducing cheaper bricks. A sample of sludge was analyzed for chemical constituents, plasticity value, particle size and content of organic matter. Sludge bricks incorporating 10 % of waste material by weight were prepared. The quality of sludge bricks was evaluated in terms of mechanical and physical properties (compressive strength test, water absorption test and apparent density test). The obtained results have revealed that waste material is mostly composed of plastic and could be utilized for manufacturing of sludge bricks. The compressive strength and density of bricks reduced with increasing amounts of sludge. However, the compressive strength of the bricks could even meet the standard requirement.
