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.

Santa Margarita River Project - FPUD - Camp Pendleton

Santa Margarita River Project to Increase Local Water Supply

/in , /by

The San Diego County Water Authority’s Board of Directors voted in July to authorize a Local Resources Program Agreement with the Metropolitan Water District of Southern California and the Fallbrook Public Utility District for the Santa Margarita River Conjunctive Use Project.

The Local Resources Program, managed by MWD, provides funding for local water supply projects. MWD is expected to provide final approval of the project in coming months.

Earlier this year, an agreement between FPUD and Marine Corps Base Camp Pendleton settled a lawsuit that was filed in 1951 over the right to use water from the Santa Margarita River.

Water from Santa Margarita River would reduce imported water demand

The upcoming groundwater recharge project will improve existing facilities and build new facilities to capture surface runoff from the Santa Margarita River. When water flows are high, the runoff would recharge groundwater basins on Camp Pendleton. New and existing wells and pumps will transfer the groundwater to FPUD, which will treat and deliver it to customers.

Water from the river would reduce FPUD’s demand on imported water and minimize Camp Pendleton’s reliance on imported water.

Project would provide 30% of Fallbrook’s total water supply

Facilities will be constructed by Camp Pendleton and FPUD. Camp Pendleton has already constructed its own bi-directional pipeline and related infrastructure, as part of the project, which received congressional funding.

FPUD will construct groundwater extraction wells, a groundwater treatment plant, pump station, storage tank and conveyance and distribution pipelines among other things. The cost of the project is $54.4 million.

FPUD expects construction of the pipeline and treatment plant will begin this fall and take about two years. When completed, the project is expected to produce an estimated 3,100 acre-feet a year. One-acre foot, the equivalent of 326,000 gallons, can supply the average household needs of 2.5 four-person families for one year.

The project would provide about 30 percent of FPUD’s total water supply and nearly all of Camp Pendleton’s water needs.

Study to Explore New Regional Water Conveyance System

/in , /by

The San Diego County Water Authority’s Board of Directors last week approved a contract to study the viability of a new regional water conveyance system that would deliver water from the Colorado River to San Diego County and provide multiple benefits across the Southwest.

The $1.9 million contract was awarded to Black & Veatch Corporation for a two-phase study. The engineering firm conducted similar studies for the Water Authority dating back to 1996 but looked at “single use” in those studies.

“A regional system to move our independent Colorado River supplies from the Imperial Valley directly to San Diego County could be more cost-effective, while also providing multiple benefits for California and the Southwest,” said Kelly Rodgers, director of the Water Authority’s Colorado River Program. “The study will assess the potential for new regional and public-private partnerships and funding opportunities.”

Three potential pipeline routes studied

The Water Authority currently pays the Metropolitan Water District of Southern California to transport Quantification Settlement Agreement water through the Colorado River Aqueduct to San Diego.

The pipeline under study would be designed at a capacity to convey the QSA water, which in 2021 will reach its full amount of 280,000 acre-feet of water annually. The current Water Transfer Agreement between the Imperial Irrigation District and the Water Authority continues to 2047. But both agencies can agree to extend the transfer another 30 years to 2077.

Three potential routes for the pipeline will be considered as part of an initial screening of the alternatives during the first phase of the study. The study will also consider elements such as permit and environmental regulations, and risk, cost and economic analysis.

Phase 1 of regional water system study will take one year

The first phase of the study, projected to cost $1.3 million, is expected to be completed in summer 2020. The Board will then determine whether to go forward with phase 2 of the study.

Pending Board approval, the second phase will include the final screening of alternatives based on refinement of site layouts, pipeline alignment and tunneling requirements, and risk, cost and economic analysis. The second phase will cost $590,00 and is expected to take one year to complete.

The Board previously approved funds for this study at its June 27 meeting.

Conveyance routes would connect to All-American Canal

As the study gets underway, there are three routes under consideration. Each of those routes would connect to the tail end of the All-American Canal where it meets the Westside Main Canal in the southwest corner of the Imperial Valley.

Two of the routes would follow a southern corridor between the Imperial Valley and San Diego, with one route over the mountains paralleling the U.S./Mexico border and the other tunneling through the mountains. Both routes would end at the San Vicente Reservoir in Lakeside.

The third and northernmost route would follow the Westside Main Canal toward the Salton Sea, then flow past Borrego Springs, and through the mountains. It would eventually connect to the Water Authority’s Twin Oaks Valley Water Treatment Plant in San Marcos.

The pipeline system is one of a handful of visionary ideas being discussed by San Diego County water leaders to enhance partnerships and solutions that make sense locally and more broadly as part of Governor Newsom’s Water Portfolio Program to develop resiliency statewide.

Water Authority Board Endorses Governor Newsom’s Water Resilience Portfolio

/in , /by

San Diego, Calif. –  The San Diego County Water Authority’s Board of Directors today unanimously supported Governor Gavin Newsom’s Executive Order N-10-19, directing development of a water resilience portfolio approach that meets the needs of California’s communities, economy and environment through the 21st century. That order also advanced a single-tunnel project to move water through the Sacramento-San Joaquin Bay-Delta, instead of the two-tunnel project favored by former Governor Jerry Brown.

The Water Authority Board made its backing of the single-tunnel proposal contingent on a project financing plan that treats San Diego County ratepayers fairly through the proper allocation of project costs by the Metropolitan Water District of Southern California.

California’s Clean Energy Conundrum

/in , , /by /American Water Works Associationby Gary Bousquet and Mike Lee

San Diego – While California draws nearly one third of its power from renewables, solar and wind energy systems are periodically pulled offline because there’s not enough demand when the wind is blowing and the sun is shining. These so-called “curtailments” increased significantly between 2014 (when they were almost non-existent) and today. They could soon become a major barrier to a more sustainable future as more and more renewable energy sources are developed to meet peak demands.

Thankfully, California water agencies are well-positioned to play a pivotal role with a solution that makes the state’s electrical grid more flexible, stable and efficient. Strategic deployment of large-scale, long-duration pumped storage facilities could minimize curtailments and provide many other benefits.

Strategic deployment of large-scale, long-duration pumped storage facilities could minimize curtailments and provide many other benefits. That would help California achieve its aggressive targets to supply at least 60 percent of the state’s energy from renewables by 2030 and 100 percent from clean energy sources by 2045.

California Funds Atmospheric Rivers Research

/in , /by

A better understanding and forecasting of atmospheric rivers could improve flood control and water management in California.

The 2019-20 California state budget includes $9.25 million to pay for research into how the state Department of Water Resources can more accurately track the intensity and landfall locations of atmospheric rivers. About half of the state’s annual rainfall and 90 percent of its flooding come from such events.

“Improved forecasting and monitoring of atmospheric river storms would benefit not only California, but the Southwest, in managing our water supply,” said Kelley Gage, director of water resources for the San Diego County Water Authority. “With better forecasting, water managers could also prepare and plan for flooding events caused by the atmospheric rivers.”

Rivers in the sky

Atmospheric rivers are relatively long, narrow regions in the atmosphere – like rivers in the sky – that transport most of the water vapor outside of the tropics, according to NOAA. When the atmospheric rivers make landfall, they release the water vapor in the form or rain or snow.

“The rivers can stretch from 250 to 370 miles wide and carry a water amount more than 7 times the volume of the Mississippi River,” said Alexi Schnell, water resources specialist with the Water Authority.

The research funds were allocated to the Department of Water Resources to “improve observations, forecasts and decisions in support of atmospheric river precipitation events” as part of the DWR’s Research, Mitigation, and Climate Forecasting Program.

Volatile water resources

A new study led by Scripps Institution of Oceanography at UC San Diego suggests that a new regime of wet and dry extremes is emerging in California. The study shows that the projected increase of extreme precipitation is likely to be caused by streams of moisture in the sky known as atmospheric rivers.

The study was published July 9 in the journal Nature Scientific Reports.

“California already has the most volatile water resources in the country,” according to a news release from Scripps. “Scripps scientists discovered that the state’s precipitation, as it becomes less frequent but preferentially stronger, will vacillate even more wildly between extremes of drought and flooding as a consequence of climate change.”

The federal Bureau of Reclamation, the Southwest Climate Adaptation Science Center, NOAA, the U.S. Geological Survey, and NASA funded the study, “Precipitation regime change in Western North America: The role of Atmospheric Rivers.”

California weather extremes

“As Mediterranean climate regions around the world are becoming more subtropical, the dry season is expanding. California is no exception,” said Alexander Gershunov, a climate scientist at Scripps. “What is exceptional about California is that the heavy precipitation is projected to become more extreme. We knew this from our past work. Now we have identified the mechanism responsible for this bolstering of extremes, and that gives us a more nuanced understanding of what to expect from future hydroclimate and a clearer interpretation of ongoing changes.”

 

Atmospheric Rivers helped California's snowpack in Winter 2018-19.

For the year-to-date 2019, the precipitation total was 19.05 inches, 3.74 inches above average, and the wettest such period in the 125-year record. Graphic: NOAA

Atmospheric Rivers boost snowpack

During the 2018-19 winter, atmospheric river events significantly increased snowpack in the Sierra Nevada and the Rocky Mountains. Both areas are key sources of water supply for the Southwest, including California and San Diego County.

Precipitation in the contiguous U.S. was above average from January to June 2019, according to a NOAA climate report released this week. The report said the 19.05 inches during the six-month period was 3.74 inches above average and the wettest such period in the 125-year record.

The January-to-June 2019 precipitation map showed California’s statewide precipitation was “above average” and “much above average.”

Safe Drinking Water Fund Passes California Legislature

California Legislature Passes Safe Drinking Water Fund

/in , /by

The state Assembly and Senate passed legislation to provide $130 million to provide safe drinking water for Californians lacking access to healthy water.

The state Senate approved the bill 38-1 Monday. The Assembly passed the bill 68-0 on July 5.

The legislation now heads to Gov. Gavin Newsom for his signature.

No water tax

Newsom and others in the Legislature had proposed a tax on residential water bills to pay for projects to provide safe drinking water for residents that don’t have access to it. Water industry groups, including the San Diego County Water Authority, were among the broad coalition of water, business and civic interests that opposed the tax.

“Thanks to the efforts of Senate President Pro Tem Toni Atkins and her staff, Californians will not face a drinking water tax,” said Glenn Farrel, government relations manager for the Water Authority. “Her leadership was vital to securing the funding needed to provide safe drinking water for the communities in California where unhealthy water is a problem.”

Historic funding solution

Funding to clean up contaminated water will instead come from California’s cap-and-trade program.

SB 200, which creates the Safe and Affordable Drinking Water Fund, is the second part of an historic funding solution for disadvantaged communities in the state that do not have access to safe drinking water.

The first part is in the state’s 2019-’20 budget, which Governor Newsom signed on June 27. The budget allocates $100 million from the Greenhouse Gas Reduction Fund (GGRF) and $30 million from the General Fund for the current fiscal year. SB 200 provides $130 million per year from the GGRF for safe drinking water for future years until 2030.

Safe drinking water

The funding is intended to assist communities in paying for the costs of obtaining access to safe and affordable drinking water, including treated contaminated water.  Many of those residents live in the San Joaquin Valley and rural areas of the state.

Smaller water districts will also be able to tap the funds to help with their operating costs, and possibly merge with other small districts.

The California State Water Resources Control Board has identified 329 water systems statewide that serve contaminated drinking water or cannot provide reliable water service due to unsound infrastructure or lack of resources. Most of the systems are in rural areas and serve fewer than 10,000 people.

A proposed tax on California’s drinking water in 2018 was also scraped by then Gov. Jerry Brown and legislative leaders.

Local Water Providers Have Racked Up Dozens of Violations

In theory, because water is hard to come by in the arid West, it should be well taken care of.

But the West sometimes squanders its limited water. We have contaminated creeks, polluted rivers, broken bays, fouled beaches and, even today, hundreds of thousands of people across California who lack reliably safe drinking water.
