Each of the following is a basic step in determining the water use of an irrigation system zone, except:
  1. Calculate the product of GPM and minutes/week
  2. Identify length of irrigation event and frequency of events in a week
  3. Measure size of irrigation zone in square feet
  4. Take initial water meter reading, run zone for X minutes, take another reading
Explanation
Answer: C - The size of the irrigation zone is not a basic step in determining its water use. A calculation involving the amount of water used in the zone in X minutes, the length of one irrigation event, and frequency of events are all required to determine the water use of one irrigation system zone. The same procedure must be repeated for each zone to determine total irrigation water use.
