Loveland, CO Landscaping Rules: Water Restrictions (2026)

04 sets the standing rules for lawn and garden watering, backed by emergency shutoff authority. 210, consumers may not sprinkle with a hose larger than three-fourths of an inch in diameter, and a nozzle must be attached; sprinkling without a nozzle or with a nozzle opening larger than one-fourth inch is strictly forbidden. Maximum simultaneous use is capped at 10 gallons per minute for lots up to 10,000 square feet, plus 5 gallons per minute for each additional 10,000 square feet. 210, while approved clock-operated systems running at the water superintendent's designated times may use up to double that rate.

All underground systems must carry cross-connection prevention devices approved by the State Board of Health. 235 gives the city manager standing authority to impose an outright ban on some or all outdoor potable water uses during a catastrophic event or other emergency that leaves the water utility's supply insufficient to meet demand. The city manager triggers a ban by publishing notice in a Loveland daily newspaper specifying the effective date (no earlier than the day after publication) and exactly which uses are prohibited, and can later modify or lift the ban using the same published-notice procedure as conditions change. 170 separately bars any consumer from wasting water or leaving outlets running when not in use, on pain of having service discontinued.
