Water Conservation

The City has developed a Water Conservation Plan to manage our water resources, and plan for drought contingencies. Ordinance No. 03-35.

Water Conservation is the most effective way to make the best use of our existing water resources, and it's also a great way to save money on your household's (or business's) water bill.

Make your pledge to conserve more water as part of the National Mayor's Challenge for Water Conservation (April 1-30, 2014)

Test Your WaterSense
Did you know that the average American uses 100 gallons of water every day? But we can all reduce our water use by as much as 30 percent by taking a few simple steps, such as installing high-efficiency plumbing fixtures and using water efficiently in our yards.

The City of Olathe has teamed with the U.S. Environmental Protection Agency's (EPA) WaterSense program to help consumers conserve water for future generations and reduce costs on their water bills.

Look for the WaterSense label on home plumbing fixtures.


When Heat is on the Rise, Be Water Wise! Think WOW: Wise Outdoor Watering

In the summer months, more than 70% of the water delivered to Olathe households and businesses is used for watering lawns.  You can reduce your household's (or business's) outdoor water use with a few easy steps.

  • Select the right trees, shrubs and grasses. Plant drought-tolerant bushes, trees and grasses, or plants that are native (naturally found) in the area. They will do well with the amount of rain that normally falls.
  • Condition your soil. Of all the improvements that can be made to soil to help conserve water, adding organic matter, such as compost, is by far the most important - and as an Olathe resident, you can pick up FREE compost when it's available.
  • Mulch! A good mulch conserves moisture, keeps weeds under control, and maintains a cool soil - all of which help save water in your gardens. And as an Olathe resident, you can pick up FREE mulch.
  • Water efficiently. Heat and wind cause water to evaporate. Avoid watering on windy days, water in the cool of the day (morning) to avoid excess evaporation. Be sure to avoid watering sidewalks, patios, and driveways, and consider using a soaker hose to water plans more efficiently.
  • Limit watering to evenings and weekdays. Watering after 6 p.m. and limiting outdoor water use on weekends is a great way to be "water wise."
  • Cut it high, let it lie. Set your mower blade higher and allow your grass clippings to decompose on your lawn. Grass clippings are about 90% water, so they decompose quickly and return valuable nutrients to the soil.
  • Program your irrigation controller. If you have a lawn irrigation system, the key to watering efficiently is to obtain a controller that can handle diverse landscape and weather situations and then to program it properly.
