OPTIMIZATION OF THE CITY OF WINNIPEG WATER DISTRIBUTION-SYSTEM

A simplified representation of the city of Winnipeg water distribution system is developed and a linear programming model is formulated to r epresent this system. Six scenarios of the linear programming model ar e analyzed to determine the most efficient operating policy when the o bjective functions vary from minimizing reservoir drawdowns to minimiz ing pumping. This analysis reveals that low total pumping values and l ow maximum pumping values can be obtained if storage at the inner-city reservoirs is utilized. It is also shown that the system cannot satis fy demand during high demand periods without drawing down the Deacon R eservoir.
