1. Check your irrigation system for overspray and adjust it accordingly. 

2. Cover pools and spas when not in use. 

3. Use drip irrigation or low volume ray heads and a timer.

4. Scrutinize your watering schedule.  Plants and perennials need deep and frequent watering while multiple start times for turf can reduce run-off and waste. 

5. Maintain healthy soil by adding compost and increase water retention by using an organic mulch. 

6. Mow your lawn to 3" - the ideal height for grass, and take the time to aerate as this will also reduce run-off.

7. Consider losing your lawn and replacing it with drought-tolerant plants or an edible landscape.

8. Collect and use rainwater and greywater in your garden.
