Capturing the First Flush of Rainwater

/in , /by

The most important water to capture in your landscape is the first inch of rainfall after a dry spell. This is called the “first flush.”  

Rainfall in dry climates like the San Diego region is often a “first flush” repeatedly due to long stretches between rainy periods. 

The first rainfall washes away pollutants that have gathered on hard surfaces since the last rain. It needs to be filtered as much as possible by landscaping before it goes anywhere else, especially into storm drains that empty into the oceans. 

How much water comes off your roof? 

The shape of your roof doesn’t make any difference. The same amount of water falls on the roof whether sloped or flat. Measure a sloped roof either using an aerial view or from the ground without worrying about the slope itself. Just measure the outside edges the same way you would if it was flat, and calculate the square footage. 

Flat roofs covering a building in one contiguous shape are easier to measure. Some roofs are more complicated. Divide this type of roof into individual squares or triangles. Measure each one at a time, then add the figures together for your total roof area.  

Calculate your potential water capture  

Once you know the total roof area, you can determine the amount of rainfall it generates in gallons, then use the following formula to convert square feet to gallons.  

Formula: Rainfall in Inches x Total Square Feet x 0.62 = Gallons of Rainwater From the Roof 

Example using a 1,000 square foot roof: 1 inch of rain x 1000 x 0.62 = 620 gallons. 

San Diego’s rainfall total for “water year” 2018 was about 3.3 inches. Imagine this amount falling on a 1,000 square-foot roof. The total amount of water runoff during this water year would be 3.3 X 1000 X 0.62 = 2,046 gallons.  

Even in our dry climate, this rainfall adds up to a lot of water runoff. It’s easy to see how important it is to save as much of this water as possible in a landscape designed to be a sponge instead of a brick.

National Report Highlights Success of San Diego Sustainable Landscapes Program

/in , /by

San Diego’s Sustainable Landscapes Program ranked among the most effective landscape transformation programs in the nation in a study released today by the Chicago-based Alliance for Water Efficiency. The “Landscape Transformation Study: 2018 Analytics Report” compiled data from 14 similar landscape conservation programs in the U.S. and Canada.

The Alliance for Water Efficiency concluded that San Diego program participants reduced water use by an average of 114.8 gallons per day, or 34.8 percent. “The Water Authority has established a high benchmark for landscape transformation programs that include rigorous program requirements that result in the achievement of multiple benefits,” according to the report.

By saving about 42,000 gallons of water per project each year, Sustainable Landscapes Program participants who transformed their landscapes save enough water to supply the average four-person household in San Diego County for more than three months.

“This study highlights our success improving water-use efficiency across the San Diego region,” said Jim Madaffer, chair of the Water Authority’s Board of Directors. “We empower program participants to take a hands-on approach to WaterSmart living, and it’s gratifying to see their pride of ownership in these projects that are changing the way San Diegans think about landscapes. An enhanced environment and happy homeowners are part of the promise of sustainable landscaping.”

The national report was accompanied by a survey of more than 3,000 homeowners across North America, which emphasized that residents are ready to embrace new landscape ideals.

“Beautiful landscapes are a source of pride for homeowners, but the emotional connection we have with our outside spaces is not in conflict with a more sustainable approach. People also want to be smart water users,” said Mary Ann Dickinson, president and CEO of the Alliance for Water Efficiency, in a press release today. “Whether it’s installing a more efficient irrigation system, opting for drought-tolerant turf or re-landscaping with climate-appropriate plants, we need to communicate that a sustainable landscape can be beautiful and water-conscious.”

Empowering WaterSmart lifestyles

Efforts to develop the San Diego landscape program began in 2010 with a successful Proposition 84 grant application. Known as the SLP, the program was developed to help homeowners upgrade their yards with climate-appropriate plants, high-efficiency irrigation equipment, rainwater capture and detention features, and soil amendments. The sum of these measures results in multiple environmental benefits, including water use efficiency.

The SLP was a partnership by the San Diego County Water Authority, the City of San Diego, the County of San Diego, the Surfrider Foundation, the California American Water Co. and the Association of Compost Producers. Although the grant-funded SLP pilot has been completed, the Water Authority continues to offer and promote SLP-related programs and resources, such as classes and personalized advice from landscape design professionals, a comprehensive guidebook, financial incentives, a demonstration garden and SustainableLandscapesSD.org.

Water Authority Water Conservation Program Manager Carlos Michelon said the SLP sets high standards for efficient water use and other sustainable practices above and beyond standard turf removal programs. Participants achieve multiple benefits, including water efficiency, drought tolerance, stormwater management, water quality enhancement and aesthetically appealing designs.

“Using smart irrigation technology and climate-appropriate plants to increase water-use efficiency makes sense,” Michelon said. “Doing so while also tapping rain water as a resource, improving soil health, and creating other environmental benefits makes even more sense. That’s sustainable landscaping in a nutshell.”

Recognizing the variety of landscapes and microclimates in San Diego County, SLP resources helped to inform and empower participants each step of the way.

“When it comes to sustainable landscaping, planning and collaboration are as critical as soil amendments or detention basins, Michelon said. “The synergy resulting from our collaborative partnerships with other agencies and non-profit organizations has created even more value for participants and the region.”

Financial incentives help fund landscape projects

During a pilot period, the Water Authority and its partners provided more than 325 Sustainable Landscape Incentives to San Diego County homeowners to help transform their landscapes into beautiful, climate-appropriate mini-watersheds.

While this locally-administered program is no longer accepting applications, the Landscape Transformation Program administered by the Metropolitan Water District of Southern California is open to qualifying water customers in the Water Authority’s service area. Effective April 1, 2019, residential rebates will start at $2 per square foot, for up to $5,000 square feet. Added funding by local water agencies (where available) means total incentives may be as high as $3.25 per square foot. An online incentive calculator at SoCalWaterSmart.com identifies incentives for specific proposed projects.

The SLP was made possible by an Integrated Regional Water Management program grant funded by the Safe Drinking Water, Water Quality and Supply, Flood Control, River and Coastal Protection Bond Act of 2006, administered by the California Department of Water Resources.

Where Does Water Flow in Your Landscaping?

/in , /by

To capture rainwater and any excess irrigation inthe soil or rain barrels, it is first necessary to understand what happens when water comes off the roof of buildings and moves across the property.  

Where is water moving? 

Make a copy of your landscaping site plan, and label it “Water Plan.” It should have the position of the buildings and major landscaping structures. During a rainstorm, watch what happens to water as it comes off the roof of the house and moves through the property. 

  • Are there any low spots where water pools? 
  • Does water run entirely off the property anywhere? 
  • Do any buildings or hard surfaces such as patios appear to be damaged by water? Is the damage caused by rain, by irrigation, or by both?

Note the direction water moves around the property from one area to another, or through multiple areas. 

Turn on irrigation systems for three minutes, and make a note about where there is any pooling or runoff.  

Assess the downspouts for water volume

Use the following process to figure out how much water comes off any hard surface, whether it is a roof, patio, driveway, or sidewalk. 

First, imagine the total roof area of your garage is 20 by 20 feet square, or 400 square feet, and water flows off it in two downspouts.  

If half the water goes into each downspout, the roof size for one downspout is half your total area. In this example, that is 200 square feet. 

Multiply the square footage for your downspout area by 0.62 to get the gallons of water per inch of rain coming from your downspout. Using our example of 200 square feet, the formula is 200 x 0.62 = 124 gallons.  

Once you have this number, you can plan for the resources needed to capture this water runoff for later use using tools such as rain barrels.

Opening the Doors to Careers in Water

/in , /by

El Cajon, Calif. – Cecilia Bernal came looking for a career. Essie Mae Horne was focused on occupational advancement. Michaela Maddox-Gomez wanted to explore her options before she graduates from Mt. Carmel High School.

Bernal, Horne and Maddox-Gomez were among the approximately 250 people packing the Center for Water Studies 2nd annual Women in Water – Exploring Career Pathways symposium on Jan. 17 at Cuyamaca College. The event included nearly two dozen speakers, a half-dozen panel discussions, inspirational messages from water and wastewater industry administrators, a day’s worth of networking opportunities and a bevy of information tables.

“I’m already learning so much,” said Bernal, 30, who has worked as a waitress, retail clerk and pharmacy technician. “Water and wastewater is an important industry, and it’s definitely more interesting that what I’ve done in the past.”

Retirements create room for job growth

The opportunities are ample due to an imminent glut of retirements by an aging workforce. Forecasts call for between 1,200 and 1,500 open positions in the next three to four years in San Diego County alone, said Sandy Kerl, the San Diego County Water Authority’s deputy general manager. Forty percent of employees at the Padre Dam Municipal Water District will retire within the next three to five years, said Lisa Sorce, human resources director. Representatives from other utilities presented similar numbers.

“Our industry is experiencing a record number of job openings,” said Sweetwater Authority General Manager Tish Berge. “At Sweetwater Authority, we recruited for almost 10 percent of our workforce just this past year. In addition, water and wastewater jobs are recession-proof, especially working in the public sector. I am excited to show young women that there are great opportunities throughout our industry.”

Maddox-Gomez said she was excited to explore those opportunities.

“This is an area that is really important to our future and to my generation, and I want to learn more about it,” said Michaela, 16, who heard about the symposium from an aunt. “I want to see what kind of options I have.”

Symposium’s success a team effort

Women in Water – Exploring Career Pathways, was made possible by a grant from the National Science Foundation to promote the career advancement of women in the water industry through community college programs, industry internships, curriculum development, and outreach to high schools, transitioning military and military veterans.

Kerl, the keynote speaker, detailed the technological advances in recent years and noted there are more than 200 unique occupations in the water industry.

“If you want an exciting career, be a part of water,” Kerl said. “If you want to be a part of the future, be a part of water.”

Lisa Sorce, human relations director at Padre Dam Municipal Water District, echoed that theme. “There are so many careers in the water industry. You really have to figure out where you want to go.”

Sorce made the comment during a presentation on preparing for career advancement and promotions. For those looking to advance, Sorce said getting ready to be ready is a must. Among her suggestions: Keep an eye on who is getting promoted and find out why; secure the certifications required for positions drawing your interest; and seek out a mentor.

“Make sure your boss knows what your career plans are,” Sorce added. “Look for ways to pitch in.”

The suggestions were helpful to people such as Horne, who was so inspired by last year’s inaugural event that she recruited friends and co-workers to attend this year’s event, too.

Said Horne: “I’m looking to move forward in my career, I’m looking to network, I’m looking to see what opportunities are out there.”

Forum topics something for everyone

Discussions throughout the day ranged from a question-and-answer session during a general manager’s form, to building leadership skills, to internships, cooperative experience and volunteerism. Following a lunch break, Cuyamaca College officially dedicated its new Center for Water Studies and welcomed several dozen guests to an open house at the technology rich learning hub.

Approximately one-third of the attendees at the symposium were girls from local high schools, and scores sought advice from other attendees from the industry.

“I’ve been doing this kind of work for 30 years and I’ve never seen anything like this before,” said Tisa Aguero, a water systems tech supervisor for the City of San Diego Public Utilities. “This event is just amazing.”

A simple, quick test will tel you how well your soil drains. Photo: Greywater.org landscape soil

Take a Soil Percolation Test

/in , /by

In the San Diego region, rainfall can be unreliable and insufficient to sustain landscaping without careful planning and a little help. An alternate water source, such as irrigation, may be required.  

To make choices about the best, most efficient irrigation system for your landscape, it’s important to learn how well your soil drains.  

How does your drainage perform? 

Assessing how well water drains through your soil involves a simple percolation or drainage test. Follow these four steps: 

1) Dig a hole the size of a one-gallon plant, about 12 inches deep and 12 inches wide. 

2) Fill the hole with water and wait. Time how long it takes the hole to drain completely. This is needed to saturate the soil. 

3) Once the water has drained and none is visible in the hole, fill the hole with water again.  

4) Lay a stick or a shovel handle across the top of the hole, and measure the distance from the top of the hole at the handle or stick to the top of the water once every hour until it drains completely the second time. You may want to set a timer so you don’t forget to make your measurements. 

Percolation and soil quality 

If your soil drains more than four inches per hour: You have sandy soil. You need to add organic matter to improve the soil.

If your soil drains less than one inch per hour: Your soil needs extra help to drain. Try sheet mulching (link to page 19) 

If your soil drains from one to four inches per hour: Good news, your soil is a sponge and drains well. This is the goal.    

It isn’t difficult to build healthy, well-draining soil. Get our tips on how to create health soil here.

New Partnership Introduces South Bay Students to Water Industry Career Opportunities

/in , /by

Sweetwater Authority and Otay Water District have forged a new partnership with the Chula Vista Elementary School District to introduce fifth grade students to opportunities and issues in the water and wastewater industry – including compelling career options.

The “Hydro Station” program is designed to address a significant shortage of skilled workers entering these career fields. Water agencies are facing a wave of retirements by Baby Boomer employees and a lack of skilled workers ready to replace them. Professionals surveyed for Water & Wastes Digest’s 2018 State of the Industry Report cited workforce development as one of the most important issues for 2019. Utilities nationwide are developing new ways of reaching students to encourage their participation in the industry.

Locally, more than 2,800 people work in the water and wastewater sector at the San Diego County Water Authority and its 24 member agencies. The Chula Vista-based Sweetwater Authority, for example, anticipates a staffing crunch on the horizon. In the next five years, 50 percent of the agency’s workforce will be eligible for retirement.

Agencies restructuring educational outreach programs for 2019

While Sweetwater and Otay have conducted educational outreach programs since the 1990s, both agencies have experienced cutbacks due to budget constraints and navigated changes in science education standards.

Valuing the importance of education and working with local students, the two agencies are restructuring their educational outreach programs and focusing on partnerships with schools and community groups to reinvent and modernize the programs. The program design fits in with recent recommendations from the Brookings Metropolitan Policy Program on renewing the water workforce and creating a broader pool of prospective workers.

“We are super excited about our partnership with the Chula Vista Elementary School District and Otay Water District in service to children and their families in our service area,” said Sweetwater Authority General Manager Tish Berge. “This program is the first of its kind in our region, and we look forward to making an impact by educating our youth about the wide variety of careers that we have to offer in the water industry.”

Program launches in Spring 2019 with 5,000 fifth grade students

The initial “Hydro Station” pilot program will launch in Spring 2019 with approximately 5,000 fifth grade students from the Chula Vista Elementary School District participating in the program annually.

Students will have three dedicated days focused on career opportunities in Information and Communication Technologies, Clean Energy, and the Blue Economy. Students will learn how their strengths, interests, and values may align with career options, and hands-on activities will help them make connections to specific careers.

The new Hydro Station is at the Sweetwater Authority’s Richard A. Reynolds Groundwater Desalination Facility – an ideal location 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.

The program is funded in part by a grant from the Hans and Margaret Doe Charitable Trust. Funds from the trust cover production and distribution costs of educational materials, including field trip journals students will use during their experience at the Hydro Station.

 

 

Capture as much rainfall runoff as you can and put it to use as landscape irrigation. Photo: StevePB/Creative Commons rainfall as resoure

Rainwater as a Resource for Your Landscaping

/in , /by

During the rainy season, runoff from hard surfaces around the home such as roofs and patios can be directed to the permeable landscaping. By capturing as much rainwater as possible in the soil, it is possible to build an ecosystem that can last through the summer months with minimal additional irrigation.  

The entire built environment can be re-imagined and transformed into a living sponge. If more rain falls than can be absorbed, or if the soil is particularly impermeable, rainwater can be directed through landscaped areas to remove pollutants before it flows downstream. 

Adjusting systems to maximize rainwater capture

There are three basic steps to capturing rainwater. First, check your roof to determine where precipitation is directed after it hits the surface — whether into rain gutters, off the edge, or elsewhere. Second, choose how and where to hold excess rainwater based on this assessment. Last, consider making upgrades such as adding rain barrels or making changes in your landscaping. For instance, landscaping soil may need amendments to hold more water. 

Is your soil more like a brick or a sponge? 

If your soil is more like a brick, it will affect how landscaping is contoured to capture water. Adding soil amendments will help it become more like a sponge that retains water for drier weeks and month. If the soil doesn’t drain well, take special care to avoid drowning new plants. 

When choosing landscaping plants, match them to the soil type. If the soil is sandy, look for plants with “dry feet” that prefer free-draining soil, If the soil is harder clay, look for plants that do not mind heavy soil.

Optimal landscape soil can capture rainwater and allow it to soak in completely in 24 to 48 hours.  

Many homeowners also use rain barrels to capture rainfall before it reaches the ground so it can be released during dry times. For more information about rain barrels, go to WaterSmartSD.org for information about purchase, rebates, and a one-minute video guide to installation.
