California Moves To Boost Recycled Water

/in , /by

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.

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.”

Can Water Agencies Work Together Sustainably? – Lessons From Metropolitan Planning

/in , , /by /California WaterBlogby Jay Lund

It is said that, “In the US, we hate government so much that we have thousands of them.” This decentralization has advantages, but poses problems for integration. Integration is easy to say, and hard to do. Integration is especially hard, and unavoidably imperfect, for organizing common functions across different agencies with different missions and governing authorities. (Similar problems exist for organizing common functions across programs within a single agency.) Much of what is called for in California water requires greater devotion of leadership, resources, and organization to multi-agency efforts.

Sometimes improving your water efficiency is as simple as changing a few old habits. Photo: Karolina Grabowska/Pixabay

Indoor Water Efficiency at No Cost

/in , /by

There are many ways to use water more efficiently indoors, and a lot of these are completely free! You don’t have to go through the expense of replacing appliances or installing new ones to improve indoor water efficiency. Sometimes it’s as simple as changing a few old water usage habits.

Here are some easy ways to reduce water usage inside your home:

  • Use a bowl of water to help thaw frozen food. Did you know that running the tap to thaw frozen meats and vegetables could use up to 2.5 gallons per minute? Using a bowl of room temperature water instead can greatly improve your water efficiency.
  • Scrape dirty dishes first before rinsing them. Not only will this save you time at the sink, but it will also conserve up to 2.5 gallons of water per minute.
  • Wash fruits and vegetables in a bowl of water instead of running water.
  • Run the dishwasher only when it’s full. Too often people are tempted to run the dishwasher as soon as the sink is empty, but standard dishwashers can use 2-4.5 gallons of water per load.
  • Turn off the water when brushing your teeth. This is possibly the easiest habit to change when it comes to water efficiency, and most people are already doing it.
  • Shorten showers to five minutes or less. Setting a timer on your watch or phone can help with this.
  • Use a bucket to collect water in the shower while you’re waiting for it to warm up. Then use this water to water your plants. Sometimes it can take a while for the shower to get to the right temperature before you step in. This is a perfect time to collect some clean water that can be reused around the house.
  • Wash only full loads of clothing – standard clothes washing machines can use a whopping 15-50 gallons per load. By running the washing machine only when it’s full, you can greatly improve your water efficiency.

The Richard A. Reynolds Desalination Facility in Chula Vista is a state-of-the-art groundwater desalination facility designed to use reverse-osmosis membrane treatment to remove dissolved salts and microscopic particles, such as bacteria and other contaminants which can be found in groundwater. The facility can produce up to 10 million gallons of drinking water per day, enough for approximately 18,000 families, and provides Authority customers with about one-third of their annual water supply.

The facility began operating in 1999 drawing brackish groundwater from five wells. That same year, the facility was honored with a San Diego Orchid award in the competition’s environmental solutions category. Its phase two expansion was completed in 2017.

The facility’s sustainable design also includes 2,950 ground-mounted solar PV panels as an alternative energy source. The solar array offsets the cost of treating water and reduces the facility’s overall carbon footprint.

The facility was previously honored with the American Society of Civil Engineers’ Project of the Year award, as well as the South County Economic Development Council’s Corky McMillin/Best of South County Award.

Summer Plant Care

/in , /by

Summer is heating up! While you’re heading to the beach or pool to cool off, your landscape might need a little help keeping cool too. Summer plant care is easy with a little planning.

Native plants

Most native Southern California plants do well in hotter temperatures if they are established before the summer begins. Avoid planting new plants, repotting, or fertilizing during the hot summer months. Fertilizing in the summer can trigger more green growth, which means an increase in water needs. During hot days, it is difficult to keep up with these needs as the soil tends to dry out more quickly.

Pruning is a great summer plant care strategy to help keep growth in check and provide pest control. Save most of the pruning for the cooler months to promote growth, but light pruning in the summer can benefit plant and tree maintenance.

Water deeply and less frequently

It might seem counterintuitive to water less frequently in the summer, but this is important for summer plant care. Watering too frequently on warmer days can cause too much water loss due to evaporation. Less frequent watering will also encourage your plants and trees to grow a network of deep roots. This will benefit them in the long term.

Protect soil with mulch

A good layer of high-quality mulch helps keep soil cool and prevents evaporation. Insulating the soil with mulch can also protect thinner roots that plants use to feed from surrounding soils. Over time, these roots will grow deeper along with less frequent watering.

Mulch is great for summer plant care, but it’s also a good investment any time of the year as it helps maintain a consistent soil moisture so you can water less.

Wait until fall to plant

Timing is important when planting new plants or trees. New plants require more water more frequently to develop their new root systems. Wait until the cooler fall months to begin planting to ensure higher rates of success.

With a little planning, summer plant care is a breeze!

Water Agencies Approve Funds for East County Advanced Water Purification Project

/in , /by

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.

Compost can be beneficial in many ways, including functioning as mulch to prevent erosion and help soil filter pollution. Photo: Ben Kerckx/Pixabay

How to Compost the Right Way

/in , /by

You can make composting on-site a goal for your sustainable landscape maintenance to reduce waste and help the soil thrive. You’ll know when the compost is ready to use when it has an earthy smell, has cooled off, and doesn’t reheat when stirred. Next, look for a uniformly dark brown or even black color. You shouldn’t be able to identify any of the original particles.

Spread compost directly on the soil surface to use it as mulch. That can prevent erosion and help plants and soil filter pollution, such as hydrocarbons and metals from road surfaces. Most greenwaste-based composts can be applied to a depth of three inches. Use up to two inches of bio-solids.

If you don’t produce your own compost on site, get it from a reputable source that guarantees high quality. Commercially produced quality can vary significantly due to the diverse nature of feedstock, processes, and maturation standards.

Use compost to make healthier soil

For native plants in your sustainable landscaping, use roughly 15 percent compost by volume to repair disturbed or damaged soils.

Clay-based soil amended with compost leads to more productive and healthy plant growth at a lower cost than amending the same soil with the necessary 45 percent sand. Therefore, you can mix poor soils that are compacted, lifeless, or subsoils with about three to six cubic yards of high quality compost per 1,000 square feet to improve the soil structure.

If your compost is based on bio-solids, it can be high in ammonium nitrogen. Use this type of compost sparingly.  When using bio-solids, be sure you know exactly where they came from.

OPINION: Vilsack: Partnerships Needed To Promote Sustainable Practices

/in , /by /Capital Pressby Carol Ryan Dumas

Testimony at a recent Senate Agriculture Committee hearing on solutions to climate change focused on what farmers and ranchers are already doing to lighten their impact on the environment and improve sustainability. They also stressed that solutions must be economically feasible, and that these are difficult times for producers to invest in new conservation practices. But Tom Vilsack, president and CEO of the U.S. Dairy Export Council and former U.S. secretary of agriculture, took the conversation to another level, pointing out the opportunities that lie in sustainable practices.

Setting Your Landscaping Objectives for Success

/in , /by

When you’ve taken the time to learn about the concepts behind the watershed approach to creating a healthy and sustainable landscape, you should step back and consider the goals you want to achieve in your garden.

If you’re facing an ocean of grass lawn and you’ve never given much thought to landscaping goals, it might be difficult to know where to start. Here are a few ideas.

Saying goodbye to grass

Remove a thirsty lawn without using any chemicals, in a way that preserves the healthy soil microbes.

Plant local California native plants that will attract birds, butterflies, and bees for pollination.

Create a child or pet friendly garden without thorns or sticky grass seed heads.

Plant fruit trees, edible vines and shrubs, or vegetable gardens.

Using water efficiently

Build healthy living soil that will act like a sponge, even if it rains a lot.

Capture all the rainwater from the roof and re-routing downspouts to fill rain barrels instead of running onto hardscaping.

Convert spray irrigation to micro or drip irrigation, with the intention of turning it off after establishing low-water use landscaping.

Make pathways and driveways more permeable.

Create a garden as a personal art gallery

Make room for a small patio with room for an outdoor table or seating.

Add pathways, Zen gardens, and interesting materials and patterns.

Integrate beautiful objects such as an art piece, interesting container collection, or items like sundials.

One goal we can all support: creating a beautiful sustainable landscape that reduces your water use by 70 percent or more.
