Unbelievable!



Really!
In the true sense of the word.

The GVW water utility is tripping itself up, with SAC members watching.

Let's just hope the appointed SAC committee members "twig on" that some of Greater Vernon Water's reports actually are misleading.
Perhaps intentionally.

Ask yourself this:

Does or does not GVW have a handle on how much
 water is treated from which source and
 whether it is destined for potable or non-potable customers,
 why is agricultural usage over- then under-reported,
why were water consultants not given correct(ed) numbers
 as they formulated what would become the
2012 Master Water Plan?


Could the incomparable (i.e. datasets of the following) reports be the reason Duteau Creek Water Treatment plant was overbuilt...which led to minimal separation of potable and non-potable waterlines over the last decade?

Many figures are not only incomparable, they're unbelievable for reasons GVW themselves provide:

"...improvements to the SCADA system over the last 3 years has resulted in some loss of data."

Plus this one:
"...leaks and theft, unmetered use of private fire hydrants, use of water for civic purposes such as irrigation at unmetered green spaces, or inaccurate water meter data (due to reporting errors or ageing(sic) meters) are also potential sources of unaccounted for water consumption."

Plus this one:
"Kalamalka Lake agricultural supply estimate from 2015 consumption and we are unable to accurately meter actual agricultural consumption from the Kal Lake source."

Plus this one:
"...data recorded in 2014 for Parks/Road medians, which is primarily irrigation water for civic lands, is likely an under-estimate of total use as this was a transition year and the centralized irrigation control system use to monitor water output was discontinued in some parks as a result of the re-organization of parks management within Greater Vernon."



Ya think?
Some data?
Likely an under-estimate?
Unable to accurately meter actual agricultural consumption?

GVW, basically, hasn't a clue of the destination
of more than one-third of the water they provide.

At issue was the first of the questions asked during SAC deliberations:
(The question is clickable, and leads to GVW's "reply").



Compare those 2012 through 2015 numbers to GVW's annual reports detailing consumption:

GVW reported that 12,639,961 m3 water was "inflow" to the system in 2014, with 6,811,837 m3 used for Agriculture. 

In this table for 2011, GVW reports agriculture usage of 7,810, Domestic/ICI category as 531.

GVW in this table for 2012 reports it includes water from all sources, and that the table represents "the most complete picture of water consumption as numbers include any water not captured by meters -- leaks, fireflows and watermain flushing". 

In this table, GVW reports 2013 metered and unmetered consumption, where metered equals 12,858 and unmetered is 3,359.  Metered consumption equates to 79% of total flow. 


Having fun yet?
Sure you are...trying to make sense of the apples/oranges data comparisons of those tables?



"They've got more excuses for bad data," offers Kia, "than Carter's got little liver pills."

Different data for different audiences.
Different strokes for different folks, as the saying goes.
So...which numbers are correct?
