City News/Important Updates

Great job, Louisville! Thanks to our community's voluntary water conservation efforts, Louisville's water use in July was 6% below the 25-year average, and 12% below average usage during a dry year. These reductions have helped Louisville preserve water resources and avoid mandatory water restrictions.

Summer may be coming to an end, but our need to continue conserving water isn't. The City is encouraging residents to end lawn watering by Thursday, October 1. Ending lawn irrigation at this point in the season will reduce demand and help preserve stored water for 2027 while presenting a relatively low risk to established lawns.

For residents, that means turning off regular lawn irrigation for the season. Targeted hand watering can continue as needed for trees, shrubs, gardens and other vulnerable plants.

To be clear, there continue to be no mandatory water restrictions in Louisville. The City is asking the community to voluntarily stop lawn watering by October 1. Voluntary conservation now can help preserve Louisville's water supply now and for the future.

How we're managing public spaces during a drought

Like residents, the City is being mindful of the water we use and is taking measures to reduce water use in parks and other shared public spaces. We are carefully managing irrigation, reducing or eliminating it where possible, and only using the water needed to protect established turf, trees, and landscaping. We’re also using reclaimed water where available.

At the same time, some of these shared community spaces and public investments need a minimum amount of water to prevent long-term damage. For that reason, you may still see sprinklers running at night in some City-managed spaces beyond October 1. Parks, fields, and other public landscapes give everyone places to play, gather, and enjoy the outdoors. Properly maintaining these assets helps ensure that they remain safe, usable, and available for the community — now and into the future.

Why we haven’t started mandatory restrictions

With only a short time left in the watering season and residents already reducing water use, the City has decided to continue to ask for voluntary conservation rather than move forward with mandatory restrictions. Water conditions and conservation needs vary by community. While some neighboring communities have implemented mandatory restrictions, Louisville's voluntary conservation efforts are reducing demand and helping us manage the dry conditions.

Saving water now will help protect our supply if drought continues or worsens into 2027. We’ll continue monitoring our water supply and provide updates as conditions change. In the meantime, please continue to be mindful of your water use. Every drop counts!
