How Much Water Do Plants Need?

It’s important to assess how much water your outdoor plants need to stay healthy. The heat and humidity in San Diego County is far from over, with the official start of Fall September 23. Irrigation needs are generally highest during these warm months.

Did you know that plants can be classified by their water needs?

Landscaping professionals use a resource called the Water Use Classification of Landscape Species, or WUCOLS, to classify plants according how much water they need to thrive.

It might sound complex, but it’s very useful because it breaks down the water requirements for each type of plant. There are four categories: Very Low, Low, Moderate, and High. These water requirements are also called Plant Factors. They are an important tool for transitioning to a more water-efficient landscape. By knowing exactly how much water your plants need, you can cut down on your water usage while also keeping your plants happy.

Calculating water requirements for outdoor plants

To calculate a Plant Factor, compare the plant’s water use to cool season grass in a given climate zone.

Why is that? Turf is among the thirstiest of all types of plants. When you replace turf areas with climate-appropriate plants with lower water requirements, and irrigate them with more efficient systems, you can greatly increase your water efficiency. You don’t have to turn your landscaping into a dry moonscape to do it.

Plant factors, or PF, categories:

Plant Factor categories from high to low water use. Graphic: Water Authority

High: Plants need from 60 to 100 percent of the water needed for a grass lawn (PF of 0.6 – 1.0)

Moderate: Plants need 30 to 60 percent of the water needed for a grass lawn (PF of 0.3 – 0.6)

Low: Plants need 10 to 30 percent of the water needed for a grass lawn (PF of 0.1 – 0.3)

Very Low: Plants need 10 percent or less of the water needed for a grass lawn (PF of less than 0.1)

Group plants by PF to irrigate more efficiently

In the Water Authority’s Sustainable Landscaping guidebook, plant selections are color-coded to identify their water needs under this system. That approach provides an easy way to group plants by their water requirements in your landscape, so you can irrigate more efficiently.

This article was inspired by the 71-page Sustainable Landscapes Program guidebook available at SustainableLandscapesSD.org. The Water Authority and its partners also offer other great resources for landscaping upgrades, including free WaterSmart classes at WaterSmartSD.org.

New Educational Hydro Station Project Opens in Chula Vista

The first Hydro Station in California opened August 15 in Chula Vista.

The interactive educational space is a joint partnership between the Sweetwater Authority, Otay Water District, and the Chula Vista Elementary School District.

The Hydro Station, at the Richard A. Reynolds Groundwater Desalination Facility, features learning exhibits and hands-on activities to introduce fifth grade students to the ecological cycle of water, water conservation, water quality, and careers in the water industry.

More than 4,000 students are expected to visit the Hydro Station annually.

Making the world ‘a better place’

“The Hydro Station introduces our students to the world of work in the water industry and inspires them at an early age to consider careers in science, technology, engineering, art, and mathematics,” said CVESD Superintendent Dr. Francisco Escobedo. “With this station, we expose students to careers that can change the trajectory of entire families, opening the door to high-wage careers that our students might not have thought were possible.

“The students also explore ways to make the world a better place through clean water, and water conservation,” added Escobedo.

New generation encouraged to consider careers as water industry professionals

More than 2,800 people work in the water and wastewater sector at the San Diego County Water Authority and its 24 member agencies. One-third of these industry professionals will be eligible for retirement in the next few years.

“It’s an opportunity for a new generation to join us in our mission to deliver safe and reliable water to hundreds and thousands of people in communities that rely on us as water professionals,” said Tish Berge, Sweetwater Authority general manager.

As part of the Hydro Station experience, students will have three dedicated days focused on career opportunities in Information and Communication Technologies, Clean Energy, and the Blue Economy. They will learn how their strengths, interests, and values may align with career options. Hands-on activities will also help them make connections to specific careers.

Hydro Station mission is about education and conservation

“I have served many years in the water industry, which has allowed me to experience the evolving industry climate firsthand,” said Mark Watton, Otay Water District general manager. “The high level of retirements, new technologies, and increased demand for safe drinking water all contribute to the availability of good, stable careers and employment.”

“We want to make sure that a rewarding career in the water and wastewater industry is within reach for as many local students as possible who are vocational or college bound, and the Hydro Station helps us do that,” he added.

The Hydro Station’s location is ideal to educate students on how their strengths, interests, and values can connect with careers in the water industry while presenting opportunities to solve real-world problems through the Engineering Design Process. It will also serve to educate children and their families, as well as the community, on the thoughtful use of water resources.

Helix Water District, Sweetwater Authority Offer Smart Leak Detector Rebates

The Helix Water District has rolled out a new smart leak detector rebate program. Helix and Sweetwater Authority customers can get a rebate of up to $100 when they purchase a smart leak detector.

The detectors sync to smartphones, allowing customers to monitor water use 24/7 via smartphone and the devices notify customers of leaks and water consumption amounts.

Smart Leak Detectors

There are two types of smart leak detectors: plumbed devices and external devices, according to Helix.

  • Plumbed Devices
    Plumbed devices are plumbed into your existing water lines. Most of these devices can automatically shut the water off at their point of installation, or allow you to shut your water off remotely, in case of a leak. Since these devices tap into your existing plumbing system, a licensed plumber and permit may be required for installation. Plumbed devices are typically more expensive than external devices.
  • External Devices
    External devices attach to the outside of your water meter, typically with some type of strap, making them simple to install. Since external devices are not directly attached to your plumbing system, they do not have the ability to automatically shut off your water, or allow you to shut off your water remotely, if a leak occurs. External devices are typically less expensive than plumbed devices.

Measure All of Your Water Use

To monitor indoor and outdoor water use, install the leak detector before the point where your irrigation line branches off. This way, the device can alert you of faulty irrigation programming, broken sprinklers or outdoor leaks. This is important, because outdoor use is about half of a typical home’s total water use.

To monitor indoor water use only, install a smart leak detector on your water service line after the point where your main irrigation line branches off.

July is an ideal month to perform a check on current irrigation systems and determine whether any practices can be improved to save water. The San Diego County Water Authority offers these nine Smart Irrigation Month tips:

  • Select sprinkler heads and nozzles that apply water uniformly to the target area.
  • Inspect your sprinkler heads regularly to make sure they are not obstructed or watering onto pavement or other hardscapes.
  • Upgrade to a smart controller. Weather and soil moisture-based controllers can automatically adjust your watering schedule based on the conditions at your location.
  • Use drip or low pressure, low volume irrigation which applies water directly to the base or roots of plants.
  • If water is applied too quickly, it can run off into the street or sidewalk. Smart irrigation regulates water pressure, ensuring water has a chance to soak into the ground.
  • Less is more when watering turf. Water long enough to soak down to the root zone, then don’t water again until the soil is completely dry. If the grass springs back when you step on it, it has enough water.
  • The greatest waste of water in landscape irrigation comes from watering too much, too fast. Instead of watering 20 consecutive minutes, run sprinklers in four five-minute sessions. This allows water to soak into the soil and minimizes runoff.
  • A rain shut-off device is an inexpensive gadget to add to your sprinkler system.
  • Improve efficiency by watering at the coolest time of day. When it’s hot or windy, more than a third of the water can be lost to evaporation.

Water Payments Projected To Exceed Cash Reserves By $3.4M

The ag community at a Friday afternoon IID water conservation meeting wanted to know what the IID plans to change with water conservation payments projected to exceed the budget by $11.7 million. IID’s conservation needs under water transfer agreements with the San Diego County Water Authority and others are 303,000 acre feet. Of that, 103,000 acre feet comes from system conservation. The rest comes from on-farm water conservation.

High-Tech Tools Help Detect Possible Pipeline Problems

It’s a whole new ballgame for the San Diego County Water Authority when it comes to finding leaks in major pipelines with cutting-edge technology.

One new tech tool deployed for the first time in February actually looks like a tennis ball that floats through water-filled pipelines scanning for potential trouble.

Of course, the new device is much more complex inside than a tennis ball – in fact, the Nautilus is among the most advanced tools of its kind in the world.  It not only detects defects that are invisible to the human eye, it does so without requiring pipes to be drained, which saves a significant amount of water and disruption to customers.

Innovation Leader

The Nautilus is just the latest component of the Water Authority’s cutting-edge Asset Management Program that has been adopting and developing innovative tools for more than two decades. In fact, the Water Authority has been recognized by the American Water Works Association as a leader in the water industry for its focus on asset condition assessment, risk management, proactive pipeline replacement, and use of cutting-edge technology that saves ratepayers money.

“These high-tech tools are cost-effective and fit perfectly with our proactive approach to managing our infrastructure, including 310 miles of large diameter pipelines and 1,400 pipeline structures,” said Nathan Faber, an operations and maintenance manager with the Water Authority. “Our mission is to find potential failures in the system in advance, rather than react after a failure.”

‘Listening’ for leaks

The Nautilus uses acoustic feedback to detect leaks or abnormalities in active pipelines without causing any disruption to water service or supply, Faber said. About the size of a tennis ball, the Nautilus is placed inside a larger, sterilized foam ball, to float through operating pipelines.

For the First Aqueduct scan, 26 sensors, called synchronizers, were installed on various structures on the outside of the pipeline. Those sensors relayed information to the Nautilus as it floated between checkpoints. No leaks were discovered in the tested portions of the pipeline.

Digital Resolution

Leveraging new technology to gather data and pinpoint pipeline problems saves water and money.

“Responding or reacting after failures can cost up to six times the cost of proactive repairs,” Faber said.

He pointed to a recent pipeline repair project in La Mesa, where a Light Detection and Ranging device, or LIDAR, was used inside a pipe to provide highly-accurate digital measurements.

“The LIDAR took 1,600 measurements in five seconds,” Faber said. “The high-resolution images showed stressed pipe and verified cracking issues that allowed crews to make an efficient, proactive repair.”

Save Water During Fix a Leak Week

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.

 

Conserving Water Is Still A Priority For California. How About Other States?

The Metropolitan Water District last week re-upped its turf-removal program, providing greater incentives for homeowners to replace thirsty lawns with drought-tolerant plants. In Utah, the state’s Division of Water Resources is encouraging residents to use more water so it can justify spending $3 billion on a pipeline that will take more water from Lake Powell, which is fed by the Colorado River, a source of water for Southern California residents. This tale of two states brings up an interesting question: Is water conservation de rigueur or passé?
