Irrigation Season

When is Irrigation Season?

Pursuant to City Code Title 5, Chapter 17, establishing an outdoor irrigation season, the Public Works Director, Les MacDonald, has consulted with appropriate staff, researched temperature and precipitation information, and determined that the 2015 Irrigation Season for the City of Moscow shall start May 1st. 

Since the implementation of the Irrigation Season program by the City of Moscow, this is the earliest the season has opened.  This is a result of the abnormally dry and warm spring weather conditions experienced in 2015.

Note: Watering of impervious surfaces is prohibited at all times.

What is Irrigation Season?

In 2007, a new Water Conservation Ordinance was accepted by the City Council. The first conservation ordinance was established by the City in 2004. That ordinance has since evolved into the 2007 ordinance, with two major amendments:

  1. Declared Outdoor Season: The allowed dates of the Outdoor Irrigation Season will vary each year and will be dependent on the current year's climate. Visit this website each year to find out during which months you are allowed to irrigate. Outdoor irrigation shall be prohibited at all times not within the declared Outdoor Irrigation Season. For new landscaping, apply for a variance with the Water Department:  Variance Application
  2. Prohibits the Watering of Impervious Surfaces: Examples of impervious surfaces include gravel, asphalt, concrete, brick, or a combination thereof. Make sure your sprinkler heads are not spraying into the sidewalk or street. For help with getting your system running efficiently, take a look at some lawn watering tips.

This can be a little confusing, so hopefully the boxes to the right can help to clarify when you can and cannot water. The City offers a variety of hardware and tips to help you with your efficient landscape goals.
