This slide presentation outlines an integrated approach to construction and startup of the 96 mgd Lakeview Water Treatment Plant (WTP) for the Region of Peel, Ontario, Canada. The scope of work is outlined as follows: regulator-mandated upgrades in the existingconventional plant;new 25 ML (6.6-mg) finished water reservoir;added 760 ML/d and 550 ML/d (200-mgd and 145-mgd) of high and low lift pumping capacity,respectively;new 363 ML/d (96-mgd) treatment process withozone, biologically active carbon contactors,ultrafiltration, and chlorine; and,cost for full scope US$1.33/gpd (treatment aloneUS$0.85/gpd), including engineering andcontingencies. Project challenges and solutions are divided into two categories, Technology andProject Delivery. Issues concerning Technical challenges included: breaking new ground with treatment process; hydraulic and supervisory control and data acquisition (SCADA) integration of existing plantand expansion; dealing with process water duringcommissioning without going to distribution; not feasible to provide temporary facilities to treat,store or recycle of 363 ML/d process flow; and, membrane maintenance takes time and effort. Issues concerning delivery challenges included: pre-purchased equipment vs. pre-selection; and, administration of multiple contracts by owner and consultantwithin schedule and overall site.
