Stopgap Efforts Aim to Ease Water Shortages

Farmers and water agencies throughout California are turning to the "Three Ts"—water transfers, trades and treated wastewater—as they try to fill some of the supply gaps caused by drought and resulting water shortages.
In farming communities around the state, neighbors are helping each other, for example by running pipes from more productive wells to a neighbor's farm.
Late-season rains improved the possibility for water transfers among water districts. More regions are delving into making treated municipal wastewater available for irrigation.
"It's definitely an 'all-hands-on-deck' approach to an emergency situation," California Farm Bureau Federation Water Resources Director Danny Merkley said. "Some of these stopgap efforts may help farmers prevent orchards or vineyards from dying. We have been encouraging state regulators to remove bureaucratic barriers to short-term water supply plans, while keeping ourselves focused on the continuing need for long-term water storage projects."
In one new initiative, the Sonoma County city of Healdsburg has moved ahead with plans to make 1 million gallons a day of treated wastewater available for vineyard irrigation and construction uses.
Efforts to make the water available began in mid-February, and the first deliveries through two 6,600-foot pipelines began last week. A new, purple hydrant outside the city treatment facility offers free water to farmers who sign up to take supplies by tank truck.
The city estimates the current supply will augment irrigation for about 25,000 acres of vineyards.
Healdsburg Mayor Jim Wood told people gathered to celebrate the treatment plant's first transfers to tank trucks that gaining the necessary permits for the project "turned out to be a lot harder than we thought." Wood said officials worked hard to finalize the project "in an amazingly short amount of time."
The chair of the State Water Resources Control Board, Felicia Marcus, praised the Healdsburg project as an example of local leadership backed up by the work of the regional water board.
"To make recycled water more readily and easily available for other appropriate agricultural and outdoor uses, the state board has proposed a general permit to allow recycled water projects to opt into, or enroll, in a pre-permit program," Marcus said, adding that the new permit program is scheduled for adoption in the first week of June.
There currently are about 250 water recycling plants operating statewide, with more planned for the future. About half of all treated wastewater produced in the state is used for irrigating crops, with additional projects in the planning stages.
"Water recycling will certainly be part of the solution for California's long-term water problems, but farmers who use recycled water should not forfeit their existing, long-term water rights," Farm Bureau's Merkley said, "and the state's water portfolio must also include a commitment to build new storage facilities, both above and below ground, to add the flexibility our current water system lacks."
Water transfers can add short-term flexibility to the system, he added, noting that some transfers appear to be underway this spring to bring partial supplies to certain water-short farming regions.
"People are doing the best they can with the limited water supplies this year, but it won't be enough for many farmers and rural communities that will still face crop failures, job losses and severe economic hardship," Merkley said. "This is going to be a tough year for many people in many parts of California. We hope we can avoid such severe water shortages in the future by investing now in new storage plus recycling, desalination and other strategies to move our water system into the 21st century."
