Saleem Mahmood – District of West Vancouver and Tjaart Van den Berg – Landinfo Technologies present the benefits of Water Metering.
For all the effort put into collecting and distributing potable water, shouldn’t we ensure that the consumer is aware of the costs of providing an “unrestricted” water supply?
Using Environment Canada’s statistics of water metering, shows that the average daily residential flow is lower where the percentage of residences metered is high. In West Vancouver the situation was dire”
you know that every day, the average Canadian uses 589 litres of water;
the average resident of British Columbia uses 677 litres; the average
GVRD resident uses 578 litres, and the average West Vancouver resident
uses 788 litres of water?
West Vancouver’s reduction target was 15 to 30% – able to be achieved through metering. They have installed 12,732 meters – gaining a 20% reduction in overall production.
Universal Metering has these benefits:
- Water Efficiency and Environmental Stewardship
- Economic Management Benefits
- System Management
Tjaart presented the software, SWIFT, a web and desktop interface software to manage water meter data and anylyze individual water usage over time.
Some interesting ideas:
- The consumption at every parcel could be incorporated into the WaterCAD model.
- Unaccounted-for water can be easily acknowledged in this model.
- Management of tariff scenarios – based on historical data.
Monthly readings provide more usable results than quarter readings
Identifies faulty meters early
more accurate water consumption projections
Bulk Meters need to be optimized
Wireless meter readings is effective and provides quick results.
NPV shows metering is cost effective
