Fix a Leak, Protect a Creek

Join others around the nation in celebrating National Fix a Leak Week, March 13th-19th, 2023! This week is a great reminder to not only step up efforts to find and fix leaks inside and outside your home to save valuable water and money, but to also learn how to better manage outdoor leaks and irrigation runoff to prevent water pollution. An average household's leaks can account for nearly 10,000 gallons of water wasted every year with ten percent of homes having leaks that waste 90 gallons or more per day. Runoff from outdoor leaks can carry pollutants such as pet waste, trash and yard waste, fertilizers, and pesticides to storm drains which can end up untreated in our local waterways and cause harm to our environment.

Follow these tips to prevent water pollution and water waste.

  • Fix leaks and sprinklers – Fix sprinklers and other outdoor water leaks immediately. An irrigation system that has just a small hole about the thickness of a dime can waste about 6,300 gallons of water per month. If your garden hose is leaking, replace the nylon or rubber hose washer and ensure a tight connection. Watch the County of San Diego’s video on Stormwater Best Management Practices for Irrigation Repair for simple fixes for your irrigation system. For more involved repair work and to ensure your in-ground irrigation system is not leaking, consult a local irrigation professional certified by a WaterSense labeled program.
  • Ensure sprinkler system and timer are operating efficiently – Check your irrigation system to look for water efficiency improvements, and test it to ensure the zones are programmed correctly. Use the EPA’s WaterSense brochure, Is Your Watering Under Control? to reduce waste and prevent polluted runoff from leaving your property. Learn more about the mechanics and programming options of your irrigation timer by watching the instructional video Understanding Your Irrigation Controller.
  • Irrigate intelligently – Adjust sprinkler heads so they don’t spray onto streets or sidewalks. Water in short cycles and in the early morning or late evening when it’s cooler outside to allow water to absorb into the soil. Use a watering calculator to receive customized watering schedules for your landscape. For more information on how you can best utilize your timer, check out the County of San Diego’s video on Stormwater Best Management Practices for Irrigation Controllers and Timers.
