O.C. Water District Approves Updated Terms For Buying Water From H.B. Desalination Plant If Poseidon Gets Final Permits

/in , /by /Los Angeles Timesby Priscella Vega Mentioned: San Diego County Water Authority

Despite pushback from about 80 environmentalists and other residents, the Orange County Water District board Wednesday approved an updated term sheet for buying water from the proposed Huntington Beach ocean desalination plant. The 6-2 vote established the terms for a contract if plant builder Poseidon Water receives final permits necessary from the Regional Water Quality Control Board this year and the California Coastal Commission next year. It also increased its project study budget from $320,000 to $370,000 to hire consultants to help evaluate different aspects of the proposal. Board members Roger Yoh and Bruce Whitaker dissented, James Vanderbilt abstained and Philip Anthony was absent.

Desalination Plant Brings Relief To Ensenada Residents Struggling With Limited Water Supply

/in , /by /The San Diego Union-Tribuneby Sandra Dibble

Baja California’s first utility-scale desalination plant has launched operations, supplying 5.7 million gallons a day of converted seawater to municipal water users in the port of Ensenada. The reverse-osmosis facility, which has the capacity to double in size, is seen as a critical piece of infrastructure for Ensenada, whose 390,000 residents have been almost entirely dependent on aquifers for their water supply.

OPINION: State Water Board’s Delta Plan Is No Fix For Fish And Hurts Farms

/in , /by /Water Deeply (New York)by Mike Wade

In announcing its new Bay-Delta Water Quality plan, the California State Water Resources Control Board said it wanted to “change the channel” on California’s water debate. We completely agree it’s time to move away from outdated thinking and embrace new, collaborative, science-based solutions and therefore are puzzled that the board is stubbornly clinging to the same failed approach of the past.

Federal Watchdog Urges Better EPA Oversight After Flint Water Response

/in , /by /USA Todayby Carlos Osorio

A federal watchdog is calling on the Environmental Protection Agency to strengthen its oversight of state drinking water systems nationally and respond more quickly to public health emergencies such as the lead-in-the water crisis in Flint, Michigan. In a 74-page report released Thursday, the EPA’s inspector general report pointed to “oversight lapses” at the federal, state and local levels in the response to Flint’s contaminated drinking water.

Heat To Build, Elevate Fire Danger In Southwestern US Next Week

/in , /by /Accuweatherby Renee Duff

Near-record heat will set the stage for a heightened risk of wildfires in the southwestern United States, including Southern California, next week. While the Southwest is no stranger to intense heat in the summer months, the upcoming pattern is likely to put several decades-old high temperature records to the test. The area of high pressure that has brought record-breaking temperatures to the South Central states will build westward from Sunday into the middle of next week, according to AccuWeather Senior Meteorologist Ken Clark.

Knowing Your Plants’ Water Needs

/in , /by

Landscaping professionals use a resource called the Water Use Classification of Landscape Species (WUCOLS) to classify plants according to their water needs.  

It might sound really complex, but it’s really useful because it breaks down the water requirements for each type of plant into four categories: Very Low, Low, Moderate, and High. These water requirements are also called Plant Factors, and they are an important tool for transitioning to a more water-efficient landscape. 

Water Requirements by Plant Factors 

To come up with a Plant Factor for a given plant, that plant’s  water use is compared 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 realize a tremendous amount of water savings. There is no need to turn your landscaping into a dry, brittle moonscape to do it.  

Here are the Plant Factors, or PF, categories:

High: These plants need from 60 to 100 percent of the water needed for a grass lawn (PF of 0.6 – 1.) 

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.   

 

 

  

Here’s How The Largest Dam Removal Project In The U.S. Would Work

/in , /by /Water Deeply (New York)by Tara Lohan

No one is popping the champagne corks just yet, but the process to remove four hydroelectric dams on the Klamath River just took a big step forward. On June 28, the Klamath River Renewal Corporation released the Definite Plan for the Lower Klamath Project, a 2,300-page detailed analysis of how the reservoirs would be drawn down, the dams removed, the materials disposed of and the formerly inundated land restored.

1954: Final Pipe Installed for Pipeline 2, San Vicente Aqueduct

/in , /by

Thanks to an intensive lobbying effort and consensus building by the San Diego County Water Authority’s first chairman, Fred Heilbron, the San Vicente Aqueduct’s second pipeline was constructed between 1951 and 1954.

The effort paid off when the second pipeline, parallel to and the same size as the first, began delivering water to the San Diego region. But even the doubling of capacity was insufficient to supply the growing population. The Water Authority had grown to 18 member agencies, and was four times the service area it had when it was originally formed ten years earlier in 1944.

Planning immediately began for a third pipeline, Pipeline 3.
