San Diego Water Pros Aid Paradise Irrigation District Following Camp Fire

Six water professionals from the Helix Water District and Padre Dam Municipal Water District spent one week in August assisting the Paradise Irrigation District with disaster recovery in the wake of the devastating Camp Fire.

The Camp Fire burned through the town of Paradise, California in November 2018. CAL FIRE reported the fire burned 153,336 acres, destroyed 18,804 structures and resulted in 85 civilian fatalities and several firefighter injuries. The Camp Fire is the deadliest and most destructive fire in California history, according to CAL FIRE.

Ten months later, Paradise remains hard at work on recovery efforts.

The fire caused significant damage to the Paradise Irrigation District’s infrastructure. As a result, more than 10,500 customers fell under a “Do Not Drink” advisory due to contamination from several harmful volatile organic compounds in distribution pipelines.

Padre Dam employees Austin Darley and Jesse Knowles, and Helix employees John Wilson, Dan Baker, Eric Hughes and Bryan Watte, spent a week in Paradise working to help ensure water system safety. While most customers have water service restored, the water quality is being carefully monitored.

“The majority of the work we did revolved around keeping customers in water during a three-day testing period, and reestablishing water service through a plastic jumper after samples had been drawn,” said Darley.

State emergency assistance system activated to provide mutual aid

Helix and Padre Dam are among 14 member agencies and the Water Authority participating in the California Water/Wastewater Agency Response Network, or CalWARN, to support and promote statewide emergency preparedness, disaster response, and mutual assistance processes for public and private water and wastewater utilities.

“This program is like an insurance policy that can provide assistance when an emergency becomes larger than our internal resources can deal with,” said Melissa McChesney, Padre Dam Communications Manager. “The situation Paradise Irrigation District finds themselves in is a good example of this. We also have agreements with neighboring water agencies in which we call upon each other for equipment or staffing when needed.”

The agencies identified staff with the skills and experience to help the Paradise Irrigation District. All agreed to volunteer for the mutual aid mission. Padre Dam employees Jesse Knowles and Austin Darley were selected to help.

“Jesse and I feel very blessed to work for an organization that is passionate about helping those in need,” said Darley. “It was an important reminder that recovery efforts continue long after the disaster leaves the news. Paradise is still in need of our thoughts, prayers, and help.”

Recovery effort not over for Paradise Irrigation District

“There’s a lot of work up here but the town is healing,” wrote Helix employee Dan Baker while working in Paradise. “I think I speak for all four of us when I say I’m proud to be a part of this.”

Water service for burned lots will be replaced as recovery progresses and new homes are built.

“It is a privilege to have the opportunity to assist our fellow Californians with this recovery effort,” added Darley. “Although we exist 600 miles apart we all have the same goal, to deliver safe and reliable drinking water to our residents and communities.”

California Moves To Boost Recycled Water

A new plan recommends four strategies to advance water reuse in California over the next three decades – an important part of both the state and regional water resilience portfolio.

The California WateReuse Action Plan includes a comprehensive set of proposed actions that will more than double the use of water recycling in California and help prepare the state for the impacts of climate change, according to WateReuse California, which released the plan in July.

But getting to that goal will require several steps, including: Completing research to advance water recycling and potable reuse; developing and streamlining recycled water regulations and permitting; increasing grant and loan opportunities to expand recycled water infrastructure; and, implementing integrated regional planning.

The U.S. EPA is developing a similar plan to advance water reuse nationwide.

San Diego water agencies collaborate on plan

Recycled water is expected to be the next major source of local water supply for the San Diego region – and the region has a long history of working together toward that goal.

The San Diego County Water Authority collaborated with its member agencies to provide feedback on the plan’s development.

“We appreciate how this new plan aims to increase water supply diversification, including recycled water,” said Lesley Dobalian, principal water resources specialist with the Water Authority, and a contributor to the final action plan.

“Within the next 15 years, potable reuse and recycled water is projected to make up more than a quarter of San Diego County’s supply, but reaching our potential will depend in part on statewide implementation of the plan’s key findings,” Dobalian said.

Increasing San Diego County's Water Supply Reliability through Supply Diversification

Water Resilience Portfolio

In July, the Water Authority Board endorsed Governor Gavin Newsom’s Executive Order N-10-19, directing development of a water resilience portfolio approach that meets the needs of California through the 21st century.

On July 18, state officials toured San Diego County water infrastructure to see the region’s successful water portfolio approach for supply diversification, as they work to create the statewide water resilience portfolio.

In San Diego County, several agencies are developing or expanding water recycling plans, including the City of San Diego, Padre Dam Municipal Water District, Helix Water District, the City of Oceanside, and several additional projects in North County.

National water reuse action plan

At the national level, EPA is also developing a Water Reuse Action Plan, or WRAP, to advance water reuse. The Water Authority met with its member agencies and submitted comments to the U.S. EPA for the WRAP.

A draft WRAP is expected to be released by the federal agency at the national WateReuse Association Symposium September 8-11 in San Diego.

“California is widely recognized as a national and world leader in water recycling,” according to the California WateReuse Action Plan. “Recycled water supplies offset approximately 9% of the state’s urban water demands and agricultural reuse provides reliable water supplies for farmers throughout the state.”

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.

Rebates are first come, first served

Rebates are available on a first-come, first-served basis and are not guaranteed. To be eligible for this rebate pilot program you must be a customer of either Helix Water District or Sweetwater Authority and purchase a qualifying device on or after August 1, 2019.

Questions? Customers of Helix Water District can contact Helix staff at 619-667-6226 or ; customers of Sweetwater Authority can contact Sweetwater staff at 619-409-6779 or .

Lake Jennings - East County Advanced Water Purification Program - Woranuch Joyce

Water Agencies Approve Funds for East County Advanced Water Purification Project

The East County Advanced Water Purification Project is moving forward after a new funding agreement was approved.

The program’s partner agencies – Padre Dam Municipal Water District, the City of El Cajon, Helix Water District and the County of San Diego – recently approved the Interim Funding Agreement. The final vote from the County of San Diego took place July 10.

The project is expected to begin producing water in 2025.

Purified water reduces dependence on imported water

The agreement requires each agency to commit $2.35 million ($9.4 million total) toward the program, with the aim to create a new, local, sustainable, and drought-proof drinking water supply using state-of-the-art technology to purify East San Diego County’s recycled water.

“This is an important milestone toward the completion of this innovative and much-needed program, said Allen Carlisle, CEO and general manager of Padre Dam Municipal Water District. “Working together with our partners, we are moving one step closer to reducing our dependence on imported water and putting the mechanisms in place to support our economy and quality of life well into the future.”

Once complete, the East County Advanced Water Purification Program will generate up to 11.5 million gallons per day of new drinking water. This represents approximately 30 percent of current drinking water consumption for residents within the Padre Dam service area (Santee, El Cajon, Lakeside, Flinn Springs, Harbison Canyon, Blossom Valley, Alpine, Dehesa and Crest), and the Helix service area (including the cities of Lemon Grove, La Mesa, and El Cajon, and the Spring Valley area). This represents approximately 373,000 residents.

The project will recycle East San Diego County’s wastewater locally, and then purify the recycled water at an advanced water treatment facility using four advanced water purification steps producing water that is near-distilled in quality. The purified water will then be blended with water in Lake Jennings, treated again at the Helix R.M. Levy Water Treatment Plant and then distributed into the drinking water supply.

Industry Day planned for prospective designers and contractors

Next steps for the project include formation of a Joint Powers Authority between Padre Dam Municipal Water District, the City of El Cajon, and the County of San Diego to serve as the governing body for the program.

An industry day is being planned in mid-August to provide notice to prospective designers and contractors on the initiation of a selection process for the progressive design-build packages that will begin posting in Fall 2019.

Partner agencies also continue to pursue grant and loan opportunities to help fund the estimated $528 million project.

The water-recycling project is intended to diversify East County’s drinking water supply and reduce the region’s dependence on imported water. It also helps the region in achieving long-term compliance with the Clean Water Act.

Padre Dam offers tours of the East County Advanced Water Purification Demonstration Project. To schedule a tour or for more information on the East County Advanced Water Purification Program, visit www.EastCountyAWP.com.

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.

California Native Garden Wins Helix’s 2019 Landscape Contest

Matt and Lauren Kirkpatrick of La Mesa are this year’s winner of the Helix Water District’s ‘WaterSmart Landscape Contest,’ an annual competition recognizing outstanding water-wise residential landscapes based on overall attractiveness, design, efficient irrigation and appropriate plant selection and maintenance.

Compared to the thirsty turf in the Kirkpatricks’ previous landscaping, the growing, colorful and entirely native new landscaping requires much less water and creates a place of inspiration and peace for these outdoor enthusiasts. Over the two-month billing period ending this April, the home used just 13 units of water, which is almost 40 percent less than the average water use of other Helix customers. One unit is 748 gallons.

The Kirkpatricks purchased the home in 2014 with a front yard full of grass that required frequent watering and mowing to maintain a modest appearance. In the end, the lawn’s appearance was lackluster, costly, and time consuming for the couple. Taking advantage of SoCal WaterSmart’s turf removal rebate program, the Kirkpatricks tossed their turf for a beautiful native landscape with less maintenance and less water consumption.

The couple chose a native plant pallet so they could enjoy the look, feel and smell of what they love – the California outdoors.

“California natives were an obvious choice,” said Matt Kirkpatrick. “They are a reflection of our love for the plants we know closely from our experiences outdoors. Native plants make us feel at home and give us an appreciation for the beauty of our state.”

Although only a few months old, the yard already displays a wonderful spring bloom with a wide variety of colors that native landscapes can offer. There are vibrant oranges from hundreds of California poppies, reds from sticky monkey flower, blues from ceanothus, purples from lupine, yellows from yarrow and plenty of green and golds from various shrubs and grasses. At the center of the landscape is a young but promising Engelmann Oak, a signature Southern California tree among wild and urban landscapes.

Plants receive water from rainwater catchment and through an efficient irrigation system, which the couple installed. The landscape captures rainwater from the roof and diverts it into two separate swales designed to absorb the water and allow it time to soak into the soil. The two swales provide water for half of the yard and prevent rainwater from running off into the street. The remaining plants receive water through high-efficiency spray nozzles that were retrofitted onto the existing irrigation system and use less water than the previous sprinklers. The Kirkpatricks only run the system once per month during the warm season.

Native gardens are just one of many different designs of landscapes available to homeowners looking to redesign their thirsty and traditional landscapes. In addition to requiring minimal irrigation beyond rainfall, native gardens are colorful, low maintenance and provide a natural habitat for local wildlife.

Free WaterSmart Landscape Makeover classes provide blueprint for success

Like the 2018 Helix landscape contest winners, the Kirkpatricks took advantage of the San Diego County Water Authority’s free WaterSmart Landscape Makeover Program four course series to educate themselves about their options. They then chose a landscaping contractor familiar with native plants which thrive in a residential landscape to bring their plan to life.

The Kirkpatricks will receive their prizes including gift cards totaling $250 and an award certificate at the Helix Water District’s June board of directors meeting The family will also receive a ‘WaterSmart Contest Winner’ sign to display in the yard.

The annual landscape contest runs from January through April each year. Visit the Helix Water District’s website, Facebook page or Twitter for more information.

Helix Water District treats and delivers water to over 276,000 people in La Mesa, El Cajon, Lemon Grove and parts of Spring Valley, Lakeside and unincorporated San Diego County.

Drones Offer Water Agencies Cost, Safety Benefits

Water agencies across San Diego County are saving time and money while improving employee safety with drones.

Industry analysts say drone use by water agencies worldwide is growing. The Helix Water District, Otay Water District and the San Diego County Water Authority have embraced the technology, using drones to inspect and monitor facilities, and to map and survey inaccessible areas.

Helix used a drone in February to check rooftop air vents on a water storage tank in El Cajon, rather than send employees high in the sky to do it. The agency determined it was too risky for employees – even with safety equipment – and too costly to have staff inspect the vents outside the 120-foot-high Fletcher Hills Combined Tank.

“We continually look for ways to utilize technologies where appropriate to minimize facility down time and to keep staff safe,” said Carlos Lugo, general manager at Helix. “Drone technology is proving to be a useful and cost-efficient way to survey and keep the district’s facilities properly maintained.”

Drones provide a safe and cost-effective alternative for inspecting the condition of storage tank vents without placing employees at risk or taking the storage tank offline. Photo: Helix Water District

Helix uses drones to inspect interior roof supports of its water storage tanks. The supports are especially vulnerable to corrosion because they are constantly exposed to humidity and heat.

Inspecting the storage tank roof supports requires moving 30-foot-high scaffolding from one support to the next, a time-consuming and labor-intensive process. To cut down that time, Helix used a drone to get high-resolution images of the supports. The drone images showed which ones needed repair without moving the scaffolding to each support.

“Using drones for this type of inspection work is a simple, elegant and safe solution,” said Jim Tomasulo, Helix’s director of engineering. “We anticipate using drones for this and other purposes.”

Drone inspections of reservoirs, treatment plant

The Otay Water District also is finding drones useful to save money and improve employee safety.

After a two-year study and evaluation period, the district is now using two camera-equipped drones to assist with preliminary inspections of its water facilities in eastern and southern San Diego County, including 40 potable water reservoirs, four recycled water reservoirs, 20 pump stations and a recycled water treatment plant.

Drones Reduce Risk

Countywide, the Water Authority uses drones to monitor rights of way and to survey inaccessible landscapes.

When a drone was used to get images and video of steep terrain on the Second Aqueduct west of Interstate 15 and south of the San Luis Rey River, the images were 10 times higher resolution than stock aerial images. Using the drone also kept staff from being exposed to potentially dangerous conditions.

The Water Authority is also exploring using drones for future surveys and potentially at water transportation, treatment, and storage facilities, where cutting-edge technology is used to save ratepayers money.

Drones are helping the Water Authority monitor rights of way, particularly in areas of rugged terrain.

But the potential of drone use is not limited to visual photography of elevated water tanks and surveying remote areas.  Water quality monitoring is another potential application.

Water agencies can use drones with infrared cameras “to monitor water areas remotely at higher spatial resolution than ever before, at low cost and at any time,” Michal Mazur, with Drone Powered Solutions, told Waterworld.com in a recent article about the advances in drone use.
