Abstract:
The ever growing population demands more buildings, greater
infrastructure which in turn demands more use of resources. This growing use of
resources causes depletion of the current energy and water reserves. Pakistan in the
global context stands amongst one of the most water stressed nations and if the current
water usage pattern continues, it would be amongst the water scarce nations by year
2030. The depleting water resource is an alarming situation for the entire nation. The
growing infrastructure increases the amount of run-off water along with increased
demand of water supply. Sustainable construction practice is a way to address the
environmental, economical and social issues with significant focus on water efficiency.
In order to assess the water savings by water conservation a framework has been
developed to identify means and methods for reclamation of storm water. A case study
of university campus is selected to assess the impact and contribution of water reuse
on fresh water savings. The campus complex is divided into smaller zones based on
their functionality and varying surfaces. Each zone is evaluated for the amount of rain
and storm water generated using the rational method to calculate the runoffs. The
result confirmed that storm water management can facilitate significant fresh water
saving. The study in the end proffered the measures to reuse the non-potable water by
efficient technology and human behaviour.
