Here in austin, they have worked hard to shrink the amount of time allowed to water. Thankfully, the city listen to our suggestion to exempt drip...my push was for the city to reward more efficient irrigation systems that used drip , mps, moisture sensors...they chose to go to a static two day a week policy 12am to 5am and 7pm to 11.59pm on your watering day. Variences are available for large commercial properties, but no deviation from the mentioned hiurs...all variences subject to inspection by a nonirrigator. I think we are going to submit a few properties into a pilot program which will allow us to control the water. Large commercial has been difficult to color in the lines....one property has 600, 000sq ft spread out on both sides of mile roadway including medians. Multiple start times .... Thank goodness my bro watches it weekly!
