Abstract

The issue of water is gaining Egypt's attention in recent times, especially after the
start of the Ethiopian Dam and Egypt's entry into the era of water poverty, where
water is considered one of the most important natural and environmental resources.
Moreover, the constant pursuit of increasing development rates, Wherever the
residential building sector acquires a large proportion of water consumption
between different activities. The research aims to rationalize water consumption in
residential buildings by developing water supply and drainage systems responsible
for distributing water within various units and spaces. Consequently, the research
focuses on water treatment and the integration of water reuse techniques within
residential buildings. The research studies a repeated porotype of economy housing
in new cities in Egypt. The study surveyed number of users of the same levels to get
the water consumption rates per unit. The research finds that water consumption can
be reduced by 30.4% in residential units by modifying water supply and drainage
systems design Which is reflected in the cost savings. In addition, the cost of
proposed system can be returned within 2.5 years comparing to the savings cost.
