Hmmmm. Average for these numbers is about 22%. We know the Avison line is a big contributor of that. Will have to keep running it through replacement and abandonment of that line and see if we get closer to the 10% mark that the drinking water program wants. I also told Ryan of Dyer to add a project into the master plan to install a mag meter with bypass so we can calibrate. Will do as part of the new reservoir project but can keep running with our current meter to compare after new one is installed. That way we may be able to apply a correction to old numbers if that is useful.
I’m out until Tuesday. Have a great weekend.

Andy,
I would have thought we had a lot more loss in September because of all the unmetered water for the Fire fighting effort.
Ryan.

Well, we now have 5 months of Audit Data. I can’t see where we’re making any math errors yet, and Metered Usage doesn’t look wrong. I don’t know what accounts for the lower % losses in the fall.
Jan-21 Metered Usage: 19237653.284; TotalProdction: 27589772; %loss: 30.27
Dec-20 Metered Usage: 18521430.8966; TotalProdction: 27856334; %loss: 33.51
Nov-20 Metered Usage: 20213225.2998; TotalProdction: 26245831; %loss: 22.99
Oct-20 Metered Usage: 26858507.8392; TotalProdction: 29723871; %loss: 9.64
Sep-20 Metered Usage: 35909121.66252; TotalProdction: 41490533; %loss: 13.45
