AN OPTIMAL WATER RECOVERY NETWORK MODEL FOR A MOSQUE

Abstract

This work presents a mixed integer nonlinear programming (MINLP) model for cost-effective
retrofit of a minimum water network involving a multiple contaminants. This optimization
problem was performed on a water network superstructure to achieve the minimum water
targets for global water operations. The model simultaneously considers all levels of water
management hierarchy and cost constraints to select the best water minimization schemes that
can achieve the minimum water networks within a desired payback period. In this model, a
centralized regeneration and reuse system is considered to reduce freshwater consumption as
well as capital investment. The approach has been successfully implemented on a mosque case
study and yielded significant savings within a designers’ payback period criterion.
