Water Smart And Save Money This Summer
Most homeowners overwater their yards, unintentionally wasting money every time they take out the hose or turn on the sprinklers. To raise awareness of the benefits of efficient watering practices, the Irrigation Association has named July Smart Irrigation Month.
Using an automated irrigation system is one of the best ways to keep your lawn and landscape beautiful and healthy, while minimizing water waste. Make time this summer to be sure you’re getting the most out of your irrigation system, while keeping utility bills low and helping to protect the environment.
Smart Start
Creating an efficient irrigation system requires specialized knowledge and understanding of irrigation design principles and local environmental conditions — something most weekend gardeners don’t have. Complying with local installation codes is another consideration.
Even the best irrigation design won’t perform well if installed incorrectly or using inferior components. Something as simple as selecting the correct type of pipe can mean the difference between a system that lasts and one that requires ongoing repairs.
Hiring a certified or licensed irrigation professional and insisting on high-quality components is the smart way to make sure your system will operate at peak efficiency for years to come. Always get multiple bids, check references and confirm your preferred vendor is properly insured.
Smart Planning & Planting
- Consider local climate conditions, as well as your lot’s exact features. Choose appropriate turf and plant species that have low water requirements.
- Group plants with similar water needs close together and separate lawn areas from planting beds.
- Plan your irrigation zones carefully. Be sure that your system will have enough capacity, now and in the future. The more irrigation zones you plan, the more you can tailor watering even if you modify landscaping.
- Consult with your local water provider to see if rebates are available for water-efficient products. Information can be found at Tuolumne Utility District’s website;
- Check the on-site water pressure and select appropriate sprinklers. Low or high water pressure can seriously affect sprinkler performance.
- Include “smart” controls that automatically adjust watering based on rain, soil moisture, evaporation and plant water use.
Smart Installation
Use components that provide the greatest flexibility. Different plants have different watering needs, and these needs may change over time. Your system should allow you to apply the right amount of water for each type of plant by the most effective method.
- Always install excess irrigation zone capacity. Irrigation zones are areas that are watered by the same irrigation valve and plumbing. Installing extra connections now makes it easier and less expensive to expand your irrigation system later.
- Include the right backflow prevention device as required by the plumbing codes for all irrigation systems. Backflow prevention devices prevent irrigation system water from contaminating the water supply.
- Install lines deep enough to protect them from damage from aeration and other lawn maintenance.
Smart Scheduling & Watering
Schedule each individual zone in your irrigation system to account for sun, shade and wind exposure. Consider the soil type, which affects the how quickly water can be applied and absorbed without runoff. Make sure you’re not sending water down the drain by setting sprinklers to water plants, not your driveway, sidewalk, patio or buildings.
Select the right time of day; watering when the sun is low, winds are calm and temperatures are cooler minimizes evaporation by as much as 30 percent. The best time to water is during early morning hours.
Thoroughly soak the root zone (generally within the top six inches of soil for lawns), then let the soil dry. Watering too frequently results in shallow roots and encourages weed growth, disease and fungus. Instal wise water distributors and you will save money and still have beautiful plants. With the California drought entering its fifth year, saving water is essential for our environment.
