Herriman asks residents to drain sprinkler lines and insulate pipes before freezing weather

Herriman residents should shut off and drain their sprinkler systems before freezing temperatures arrive, the City said in a notice dated Oct. 21 1. Freezing temperatures can cause water left in pipes and sprinkler systems to expand, which the City says can crack pipes, break sprinkler components and lead to costly repairs 1.

Sprinkler lines should be drained so water does not freeze inside them. Depending on the system, that means opening drain valves or having the lines professionally blown out 1. The City also asks residents to disconnect and drain garden hoses, shut off outdoor faucets where that applies, and insulate exposed pipes in garages, crawl spaces and other unheated areas 1.

The notice also addresses watering. As lawns and landscaping enter their dormant season, cooler temperatures, shorter days and reduced evaporation cut how much water the plants need, and the City asks residents to adjust their schedules and stop outdoor irrigation as the season ends 1.

That matches the timing of the City's irrigation system. Herriman began the seasonal shutdown of its secondary water system on Oct. 13, when Jordan Valley Water Conservancy District had already discontinued service to the Blackridge area; the untreated irrigation supply is typically available from early May to mid-October 24. The conservancy district's own conservation guidance says lawns need far less water in spring and fall and advises adjusting a schedule to temperature, rain and soil moisture rather than watering out of habit 3.

The City says winterizing now protects a home's plumbing and irrigation system and prevents repairs when warmer weather returns 1. Its notice does not give a date by which the work should be done, or name a contractor for blowing out lines 1.
