Conclusion

Recommendations �Site investigation must be done in order to the nature of the study area. �If possible treatment plant is considered as a feasible project. �We recommend to civil engineering department to but the Arc Hydro tools in GIS course plan, because it saves a lot of time, give more accurate results, and the design process will be easier.
