Wan Alwi, Sharifah Rafidah and Abdul Manan, Zainuddin and Ujang, Zaini Efficient water demand management for urban systems based on pinch analysis. In: SOMChe 2004, UTP, Perak.
Pinch Analysis has been an established systematic technique for optimal design and retrofit of heat, mass and water recovery networks in industry to achieve maximum energy as well as mass efficiency. Until today, the application of Pinch Analysis is perceived to exclusively belong to the process engineering domain. Sharp increase in the price of fresh water has stimulated the efforts towards efficient water management in urban sector and inspired the Process Systems Engineering (PSE) Group of Universiti Teknologi Malaysia (UTM) to extend Pinch Analysis application beyond the frontiers of process industry; into the urban environment for the purpose of maximising water recovery. This paper highlights three key developments in Pinch Analysis revolution related to the urban sector - 1. Establishment of the minimum water and wastewater targets using the new water cascade analysis technique; 2. Water network design using source-sink mapping diagram to achieve the minimum water and wastewater targets; 3. Economic evaluation for urban water regeneration. A study involving the application of Pinch Analysis on Sultan Ismail Mosque in UTM yields potential maximum reductions of 79.2% fresh water and 62.7% wastewater respectively (after regeneration); a very encouraging results in terms of water savings.
