Denver Water outdoor watering rules depend on the address

A sprinkler controller does not know what year it is. Plenty of Denver lawns get watered on a schedule a previous owner set, or on the day a neighbor happens to run theirs. Denver Water assigns watering days by address, with rules that steer the heaviest watering into cooler hours, so the right schedule starts with your own service address rather than with habit.

A handful of plain expectations come with those days. Skip watering when it is raining or windy. Fix a leaking or broken sprinkler system within the listed repair window. Keep the spray off pavement, sidewalks, and streets. And when you hand-water or wash a car, use a hose with a shutoff nozzle so it is not running the whole time.

These limits also tighten during drought, which is why last year’s settings can quietly be wrong this year. The schedule that was fine in a wet spring may not match a dry one, and what a landlord or neighbor remembers may already be out of date.

So look up the current rule, match it to your address, and then do one thing more: walk the zones while they run. A head spraying the driveway or a soaked corner of the yard is not just wasted water. In a Front Range climate that swings from heat to hard freeze, the runoff becomes ice on the sidewalk, moisture against the foundation, and the kind of overspray that draws a neighbor’s call.
