In an article appearing in Orillia Matters on Aug 11th (https://www.orilliamatters.com/local-news/aggregate-pit-application-to-…), Sargeant's assistant general manager is quoted:
“One cannot get a realistic approximation of actual water taking by multiplying the theoretical maximum water-taking by the theoretical maximum days in the application,” MacMillan said. “In reality, our water pump usually only runs about three times per week, only during working hours, and doesn't run at all in the winter or periods when we are not washing.”
It then goes on to say "the Ministry of Environment form and process calculate theoretical maximums and puts the onus on Sarjeants’ hydrogeology consultant to prove that this theoretical taking can be supported at any given time. It is not intended to be used as a projection of actual water taking. "
I can understand wanting to know peak pumping rates and peak durations to ensure that the draw does not exhaust the supply in the short term.
But should they not be bound to longer term restrictions based on their projected actual usage?
Short term pump tests on well recharge do not necessarily reflect longer term performance as the draw-down surrounding the wellhead propagates outward from the well through the aquifer.
As well, perhaps we should be looking at the ecosystem services provided by the moraine, compare them with the needs of a quarry and prioritize the former against the less significant services a quarry provides?
