Louisville residents encouraged to keep conserving water, limit watering to two days per week

Thank you to everyone in our community for doing your part to conserve water this spring. We truly appreciate it! We know many of you have been eagerly waiting for an update, and we’ve started hearing a few rumors swirling around, too. So, here's an update on Louisville’s current water situation.

Water levels are stable, but we're not in the clear

• While some much-needed moisture has passed through, it was not enough to move us out of voluntary restrictions.
• There has not been a significant change in conditions, and we are still in drought-response mode.
• There are currently no mandatory restrictions in Louisville, but participation in the voluntary restrictions outlined below is highly encouraged.

Limit watering to twice a week, between 6 p.m. and 10 a.m.

• We know many folks have started turning on sprinklers after holding off in April. Thank you for waiting! You are in the clear to use irrigation systems, but the watering scheduled below is highly encouraged.
• We highly encourage you to limit watering (irrigation and hand-watering) to two days per week, between the hours of 6 p.m. and 10 a.m.
• Hand water gardens, shrubs, and trees on the same schedule.

Smart watering tips

• Aim sprinklers at grass and plants — not streets and sidewalks
• Promptly repair leaking sprinkler systems.
• Use buckets or a hose nozzle with a shut-off valve if washing your car.

City following best practices for conserving water while maintaining infrastructure

We know that maintaining what we have is a key priority for the community. Thoughtful decisions are being made to reduce water use while protecting the community's land, infrastructure, and public spaces for the long-term.

You've probably noticed that Louisville Sports Complex, Miner's Field, Coal Creek Golf Course, and Community Park are being irrigated normally. That's because these locations are irrigated with reuse/reclaimed water. Using this non-potable reuse water for turf irrigation preserves treated water supply for higher-priority needs. Reclaimed water would otherwise go unused and be returned to Coal Creek.

Ways to make your yard more waterwise Resource Central programs The City, in partnership with Resource Central, offers programs to help residents use water more efficiently and create beautiful, low-water landscapes. Available resources include: Garden In A Box kits Free sprinkler evaluations (“Slow the Flow”) Lawn replacement incentives Virtual waterwise yard seminars

Northern Water also has a variety of valuable landscape resources with a wealth of information. Take advantage of these programs to reduce water use, save money, and choose plants and grasses that are well-adapted to Colorado's climate.

Collect rainwater with a rain barrel

It's been raining — do you have a rain barrel? Rain barrels conserve water by collecting rainwater that would otherwise run off your roof and into storm drains, allowing you to store and reuse this captured water to irrigate your lawn and garden.

Keep It Clean Partnership is hosting a free rain barrel webinar on Wednesday, May 20 from 6:00–7:30 p.m. To register, or to learn more about how to choose, install, and maintain a rain barrel, visit KeepItCleanPartnership.com/RainBarrel.

New lawns

Due to the amount of water needed, if you are considering establishing a new lawn this year, we strongly recommend that you hold off. We also recommend that you opt for drought-tolerant landscaping over a traditional lawn!

Stay tuned for updates

The City continues to monitor conditions and water supply projections to make thoughtful recommendations for restrictions. We will keep you updated.

Every gallon counts! Thank you for all you've done to save water this spring. We appreciate your continued help as we head into summer.
