Drinking water treatment sludge (DWTP) is the solid or semisolid-like by-product produced mainly during the sedimentation process in the water purification process. The sludge is commonly content with nutrients and organic matter, and it has the potential to be used as a growing media. This study aims to introduce the growing media (pellets) from the DWTP for urban gardens. The present study was conducted with, seven types of pellets used with commercial pellet (T0) as a control treatment, and the rest were prepared using a mixture of water treatment sludge, coir dust, coir fiber, and active charcoal (T1- Coir dust and water treatment sludge, T2- Coir fiber and water treatment sludge, T3 and T4- Active charcoal and water treatment sludge, T5- Coir dust, active charcoal, and water treatment sludge, T6- Coir dust, Coir fiber, Active charcoal, and water treatment sludge) with different ratio based on the weight, then mixed with water properly and compress it and made as a pellet. The most preferable pellet was identified by using the plant growth performance of the Chili (Capsicum annum.-MI-2), and the best mean results were recorded in the T5 pellet as plant height of 7.2 cm, Number of leaves of 7, length of the leaves of 3.9 cm, length of the root 6.8 cm at the 28 days after sowing. In the meantime, other tested pellets showed good performance among them, the T1 pellet showed the same performance as the commercial product. Based on the results of this study, the T1 pellet shows the same characteristics as the commercial product, and the T5 pellet shows better performance than the commercial product with cost-effectiveness than the commercial product. Thus, those pellets have to be used as a sustainable sludge management strategy.
