Edfina Drinking Water Treatment Plant was installed at Behira governorate, Egypt in 1998 and, due to increasing of water demand, the water authority intends to increase its capacity by installing a new conventional water treatment plant. However, water resources are suffering from many illegal activities in the catchment which deteriorate the raw water quality. The water higher community took the decision to develop a  WSP for Edfina supply system with the Holding Company in coordination with other water stakeholders (including the Irrigation ministry, Environmental ministry, Health Minisry, NGOs….). This document is the first version of the WSP and is shared as an example of a WSP approach adopted in Egypt.
