Our "20 by 20" Conservation goal
In Madison, we use 65.2 gallons of water per person, per day. But our Water Conservation & Sustainability Plan outlines an ambitious goal. By 2020, we want to see that number drop by about 20 percent to 58 gallons per day.
Even as our population rises in Madison, good conservation practices will ensure that our overall water use as a city will stay the same. And that means paying close attention to how much water we're using on our lawns and gardens.
Indoor Vs. outdoor water use
On average, 30% of residential water consumption is devoted to outdoor use. But according to the EPA, as much as half of the water we use on our lawns and gardens gets wasted because of overwatering, improper landscape design and evaporation.
Outdoor conservation tips
- An established lawn only needs one inch of water per week. Use a rain gauge and take a look at our lawn watering guide.
- Avoid cutting more than 1/3 the length of the grass at one mowing.
- Leave grass clippings on the lawn, spreading out clumps; the clippings will disappear after giving up their moisture and nitrogen.
- Use a rain barrel. Capturing water from gutters and downspouts in a well-designed rain barrel conserves the municipal supply while providing the best water for lawn and garden.
- Use native plants, which need little water beyond normal rainfall. Or install a rain garden: City of Madison Engineering, Water Quality Initiatives, Rain Garden
