Development of a water demand strategy model on sustainable water supply system for Kuching city

Water treatment and supply are often granted a much higher priority than wastewater collection and treatment despite the fact that wastewater deserves a greater emphasis due to the impact of its poor management has on public health. A new commitment to give wastewater the same priority as water supp...

Sanitary engineering Water treatment and supply are often granted a much higher priority than wastewater collection and treatment despite the fact that wastewater deserves a greater emphasis due to the impact of its poor management has on public health. A new commitment to give wastewater the same priority as water supply is a very positive development in water demand strategy to support a sustainable water supply system.

In this thesis a mathematical model with spatial representation of real system was developed, and hence, provided a vehicle for evaluating a proposed system.
