This paper presents the treatment of municipality water using watermelon seeds as natural coagulants and bio filter in the water treatment process. A significant reduction in water physicochemical parameters was observed notably the BOD and COD by more than 79% to meet the WHO guidelines for drinking water. A process treating 25 m3/day of the water for portable uses was processed and the design of the bio filter presented. An economic assessment for applying this technology in water treatment showed a payback period of 10 months with a rate of return of 28% upon investing $295 000.00.
