This study explores roughing filtration as a viable pretreatment technique in small-community water filtration processes. The implications of this study for the design of roughing filters include: i.

pilot testing using a planned orthogonal experimental programme to design a full-scale roughing filter is appropriate and efficient; ii. the most influential design variable is filter length or   with slow sand filtration, to portray similar features.

Roughing filtration is increasingly becoming accepted as a viable and efficient natural pre-treatment alternative in both developed and developing countries (Collins, et al.,Galvis, et al., and Wegelin, ). The per-formance of roughing filters is based on a combination of Roughing filtration ca n be considered as a major pre- Evaluation.
