My sprinkler controller is an Open Sprinkler model and I wrote a program which periodically pulls the logs off it and stores them in a database. I was checking out my yearly irrigation water usage and noticed that I’m generally getting better every year about keeping the yard alive with less water. Obviously this is heavily weather dependent, but generally our summers are exceedingly dry so the main variation is in the start and stop of the watering season.
The y-axis roughly equates to the number of gallons used but this is far from accurate. The year to year comparisons are completely valid though.
I have similar data showing my HVAC (furnace, AC and fan) usage over the years but I’ll save that for another time. I don’t want to pack too much excitement into a single post.
