Since the selection of the original treatment process at the Mannheim Water Treatment Plant (WTP) in 1992, two
significant changes have occurred in the water industry:
drinking water standards have become significantly more stringent; and,
new water treatment technologies and practices have been developed that
facilitate meeting the more stringent water standards.
As a result of the more stringent drinking water standards that were introduced, the
Mannheim WTP is unable to meet its design capacity of 72 ML/d. Rather than pursuing
a plant expansion, the Region decided to evaluate the existing plant in light of the new
water treatment technologies and practices to determine how these might be applied to
meet or exceed the current drinking water standards while minimizing capital and life
cycle costs.
Through various studies over the past few years as well as an Operating Strategy Review
at the Mannheim WTP in 2004, Associated Engineering is assisting the Regional Municipality of Waterloo (RMOW) to
develop a phased implementation plan to increase treatment production capacity back to
72 ML/d. Based on the Operating Strategy Review work to date, the RMOW has
identified that the existing clarification system and filters will need to be modified in
order to achieve the design capacity of 72 ML/d while meeting current water standards.
As such, the RMOW is proceeding with a pilot-testing program that will pilot dissolved
air flotation (DAF), intermediate ozonation, and biological filtration. Includes 2 references, tables, figures.
