How to use well data to support operations and growth
Understanding the amount of water wineries can reliably draw from their wells on a daily basis can play an important role in planning for future growth.
The maximum pumping rate can be estimated by having a licensed well technician conduct a well yield test to measure the rate of water infiltration into the well.
Since well yield may vary over the course of the year, it is recommended that the yield test be conducted when water levels are lowest to obtain a conservative estimate.
While the minimum duration of a yield test is one hour, it is recommended that the pump test be conducted over a longer period (5-24 hours) in order to provide greater confidence in the ability of the well to sustain a given pump rate.
Well levels can be tracked over the course of the year to identify periods of low water availability and implement water conservation efforts or consider alternative water sources such as rainwater harvesting before water supplies reach critical levels.
Comparing average water levels year-to-year can help wineries identify longer-term trends in water availability and gain a greater understanding of typical water availability to plan for future growth.
With detailed water consumption and well level data, wineries can compare supply and demand throughout the year to identify periods where water supply is at greatest risk of falling short.
A Permit to Take Water is required if you draw more than 50,000 litres per day from wells or surface water.
If you divert and use groundwater for non-domestic purposes in British Columbia, you must obtain a water licence and pay water fees and rentals. This change came into force with the Water Sustainability Act (WSA) on February 29, 2016.
