Put Your Irrigation to the Test

/in , /by

Turn on each valve of your irrigation system, and observe how quickly water begins to run off your landscaping. Note the time when each runoff occurs. For some systems, this could be immediately. For others it may take as long as five minutes.

Make sure that the spray irrigation is never running for longer than eight minutes at any one time.

Take notes on your irrigation plan, and turn off your irrigation until you are able to fix the follow issues:

• Do you have broken sprinkler heads?
• Are there heads that are blocked by plants or objects such as planters or lights?
• When the system turns off, does water come out of the lowest heads in the landscape?
• Are any heads in need of adjustment to they don’t directly spray onto the hardscape, such as sidewalks or patios?

Adjust your sprinklers to eliminate runoff

Several things can be done to minimize runoff due to irrigation. This is among the most important factors in using irrigation efficiently.

• Tune up spray irrigation systems so there is no overspray on hard surfaces
• Do not install spray irrigation in areas that are too narrow (generally eight feet wide or narrower)
• Move spray heads 24 inches away from buildings or impermeable surfaces
• Convert spray systems to micro or drip irrigation with the lower precipitation rates, pressure regulation and a filter
• In lawn areas, be sure to follow the organic maintenance practices to keep your soil ‘spongy’
• Replace standard overhead sprayers with high-efficiency rotator nozzles, or other types of low precipitation rate nozzles

Staying on top of your irrigation system can mean the difference between maximizing your water efficiency and unknowingly wasting water running down sidewalks unused into the storm drain.

Watering your plants by hand is a great way to control exactly how much water they receive and observe them closely to be sure they are flourishing in the early stages.

Top Irrigation Tips for Smart Landscape Management

/in , /by

Use these helpful tips to get the most from every drop of irrigation applied to your landscaping through the smart use of irrigation systems and supplemental hand watering.

Keep water on your landscaping

Watch your irrigation while the system is running. Check to make sure sprinkler heads aren’t spraying water onto sidewalks, patios or structures.

If water is being applied too fast for your soil to absorb it, runoff will occur. Puddling and pooling water may be an indication your water is being applied too fast or too often. Adjust your system to prevent this from happening.

Repairs to broken pipes and sprinkler heads should be made immediately, or your system should be turned off until those repairs can be made.

Cycle and soak programming eliminates runoff

Watch how quickly runoff occurs when you’re running your irrigation. This is the maximum run time for your irrigation controller in a particular hydrozone.

Divide the total minutes required in the hydrozone into blocks of time no longer than the observed runoff time. Allow a 30-minute rest period in between irrigation cycles.

Example: If you need 12 minutes of water in a certain hydrozone, but there is runoff after three minutes, you need to break down the 12 minutes into four separate three-minute long cycles, with 30 minutes between each cycle.

Best methods of hand watering

Hand watering is especially good when your garden is getting established. You can spend more time watching your plants to be sure they are flourishing in the early stages.

When your landscape plants are new, you may need to water more frequently because roots are shallower. Roots on a newly planted one gallon plant are only four to ten inches deep. This is why it’s a smart idea to plant during the rainy season.

Before hand watering, look at your plants. Do they appear droopy? Is the soil very dry? If so, give the plants a good drink. Don’t water more than two days in a row. Let soil dry out completely before watering again. Overwatering and underwater symptoms can be similar.

Once your plants are established after the first year, your sustainable garden will not need watering more than once or twice a month – if at all. Stop watering after the first seasonal rains begin and let nature take over.

San Diego County residents have embraced the new WaterSmart approach to their landscaping, installing water-efficient gardens and removing thirsty turf in increasing numbers.

One of those swapping turf for sustainable landscaping is San Marcos homeowner Rhonda Holmes. She won the 2018 Vallecitos Water District Landscape District contest. Holmes transformed the landscape at her home shortly after buying it. Her outdoor remodel included replacing the front and backyard turf areas with water-efficient plants.

She designed a garden that was smart on water while being beautiful at the same time.

“It’s really easy to do,” Holmes said. “I’d love to see more people try to do their part.”

The contest aims to inspire residents to consider a landscape makeover by showcasing the beauty and variety of water-efficient landscapes.

Many previous winners have taken advantage of the San Diego County Water Authority’s free WaterSmart landscape makeover classes to help them successfully create and complete their projects. More than one million square feet of turf has been targeted for removal by course participants, generating a water savings potential of 36 million gallons annually.

Interested residents can learn about the next series of Landscaping Makeover classes and register on the WaterSmartSD website.

In addition to the benefits of reducing water consumption, water-efficient landscaping can improve a home’s curb-appeal and value, and reduce the need for costly, time-consuming maintenance. Many native plant selections also have fire-resistant qualities and provide habitat for local wildlife.

Outdoor watering accounts for roughly half of statewide urban use, and more in inland areas, according to a Public Policy Institute of California report. Savings can come from installing more efficient irrigation systems and replacing thirsty lawns with less thirsty plants.

Irrigation Efficiency Impacts Plant Health and Water Use

/in , /by

Irrigation systems have a lot of interconnected mechanical elements. They must be thoughtfully designed, installed and programmed. Once in place, irrigation systems must be maintained properly for optimal performance.

“Irrigation efficiency” is a way of describing how well your irrigation system is delivering water for the beneficial use of the plants in your landscaping.

Issues that adversely affect the performance of your irrigation system can greatly reduce its efficiency and cause you to use more water than needed. The issues fall in three major categories: site conditions in your landscaping, irrigation control, and the uniform distribution of water by your irrigation system.

Three ways to maximize irrigation impact

There are three ways to improve your irrigation system efficiency by upgrading and continuously maintaining it for maximum efficiency.

• Smart Irrigation Management
• State of the Art System Upgrades
• Matching Irrigation to Your Hydrozones

Intelligent irrigation begins by understanding that “setting and forgetting” your irrigation controller is a thing of the past. Even if you don’t have a “smart” irrigation controller to adjust your program for weather conditions, you should be more proactive in managing your watering, and more closely try to match your watering schedule with the actual water needs of your landscaping.

Upgrading your system with state-of-the-art components is a good investment and the single most significant thing you can do to save water.

Tips on professional help with your irrigation needs

You may decide to get professional help with your irrigation system. Look for designers or contractors qualified to provide these services. Credentials such as the Irrigation Association’s Certified Irrigation Designer designation can help assure your project will be successful. You can also ask if your contractor is a Qualified Water Efficient Landscaper (OWEL).

Contouring Tips Help You Make The Grade  

/in , /by

It’s smart to use existing depressions, slopes and contours for guidance when planning your landscape grading. If your yard is perfectly flat, you’ll need to move soil and features around to create more rain-holding contour areas.  

Do a Percolation Test, and prep your soil as needed to make it as much of a water-retaining sponge as possible before getting to work on rainwater capture plans.  

NOTE: If you are working with existing hillsides, it’s best to get professional advice before grading or other significant changes. Before any digging, call Dig Alert 8-1-1 or visit digalert.org

Basins and swales are shallow depressions or channels no more than 24 inches deep on gently sloped or nearly flat landscapes. Basins and swales move water over short distances. The plants in and around the depressions capture and sink small volumes of surface water.   

Small, shallow depressions work best in clay soil areas, while sandy soils may accommodate deeper depressions up to two feet. Channels can be planted or lined with rocks and small boulders to resemble natural creek beds. 

Berms 

Berms are mounds of raised soil, usually planted, that can border basins and swales or be used alone. They help contain and move water around, increasing the holding capacity of basins and swales   

Boulders

Save Water During Fix a Leak Week

/in , /by

Local water agencies are planning to offer rebates or professional help to customers who find and repair water leaks as part of national Fix a Leak Week activities March 18-24.

Fix a Leak Week is a reminder every March to check indoor and outdoor plumbing systems for leaks.

The Water Authority offers tips on how to identify and fix leaks around your home. Check WaterSmartSD.org for tips and for more information about Fix a Leak Week.

The U.S. Environmental Protection Agency reports that household leaks can waste nearly 1 trillion gallons of water annually nationwide. Average household leaks can account for nearly 10,000 gallons of water wasted every year – the amount of water needed to wash 270 loads of laundry, according to the EPA. Repairing a leaky toilet can save up to 500 gallons of water a day. That’s enough to fill a backyard swimming pool.

Common types of leaks found in the home are worn toilet flappers, dripping faucets, and other leaking valves. By fixing easily corrected household leaks, homeowners can save up to 10 percent on their water bills.

Sweetwater Authority offers rebates

During March, the Sweetwater Authority offers its customers rebates of up to $75 for leak repairs. Residential and business customers in the district may also schedule a free water audit to evaluate the water efficiency of their property.

Fix a leak during Earth Month in Oceanside

The City of Oceanside offers a Fix a Leak Workshop in conjunction with its Earth Month celebration in April.

A free three-hour workshop “Common Leaks and How to Fix Them” is scheduled for 9 a.m. to noon on Friday, April 26, in the Oceanside Civic Center Community Rooms.

A plumbing professional will describe how to identify and fix leaks.

Residents are encouraged to bring their questions. Attendees will receive a home water audit and leak detection kit. Attendance is free, but seating is limited. Email  to reserve a spot.

Catch the Rain By Slowing and Storing It

/in , /by

If rain gutters are installed on your house, water will be directed into downspouts, where it can move with great force and speed. This is especially true in a large storm. Instead of allowing downspouts to discharge directly on hard surfaces like a driveway, path, or patio, think about ways to redirect downspout water into vegetated landscape areas. 

One option is to replace downspouts with “rainchains” to slow down the water so it can be more easily absorbed when it reaches your landscape areas. Add a rain barrel or cistern at the bottom of downspouts or rainchains and let it overflow into the garden. 

If rain gutters are not installed, water shears off roof surfaces and can cause erosion damage. Areas under the eaves may be covered in permeable groundcovers such as pea gravel, mulch, or rocks to reduce the compacting force of water falling on bare soil. Spreading fresh leaf and wood chip mulch throughout the garden will slow down water. Healthy soil can withstand even the strongest rain.   

Ways of storing rainfall  

Rainwater can also be harvested and stored. Storage vessels include rain barrels and cisterns directly connected to downspouts  

Stored water can be released gradually into the landscaping between winter rainstorms, building up the soil sponge and ensuring that native plants get adequate water during the winter months when they need it most. If you need water in the summer and capture enough of it during the winter, you may be able to use your cistern water for irrigation  

Both rain barrels and above–ground cisterns can be relatively inexpensive to purchase and easy to install. Mosquitos are kept out using screens. With minimum maintenance and common sense, the water can be kept safe. If you plan to store rainwater, make sure the “first flush” is diverted directly into the landscaping before capturing the rainfall that follows.  

Properly placed trees also are excellent landscaping features to help capture rainfall, allowing it to be released slowly over time into the soil.

2009: Taking A Bite Out Of Water Use

/in /by

Ten years ago, the state and region were facing a water crisis — snowpack levels were below normal and water restrictions were in place.

Thinking outside the box, the Water Authority sweetened its conservation outreach efforts by partnering with the San Diego-Imperial Council of the Girl Scouts to distribute water conservation tip sheets across the region with the scouts’ popular cookies.

In March 2009, 400,000 conservation cards were handed out with 2 million boxes of cookies. “Please take a few moments to implement one or more saving tips,” the cards said. “The amount of water saved could have a huge impact on our region!”

This partnership was part of a $1.8 million outreach program that helped the San Diego region prepare for potential water supply allocations. The campaign was the Water Authority’s largest advertising and marketing effort since the early 1990s.
