歐巴馬政府宣布,聯邦政府將投注5千萬美元預算,用於提升這幾年旱災頻繁的美西12州的用水效率與水源保育。
這筆預算將用於移除草皮、改種較耐旱植物、升級灌溉系統、減少管線漏水、收集雨水、提高地下水補注和改善鮭魚生存棲地。

珍惜每一滴水
這項計畫稱為「WaterSmart」,意謂透過協力合作,企圖在水資源的供給與需求之間,尋求更有效率水資源管理策略與增進水源保育。
內政部長Sally Jewell在簽屬合作協議上說:「面對嚴重旱情,州政府和聯邦政府必須整合資源,善用與珍惜每一滴水。」
Sutley說:「聯邦政府對用水效能與回收水的計畫資助別具意義,特別是現今加州正遭逢歷史大旱。這些資金將協助許多城市朝向水資源永續使用的目標、未來還可興建當地供水站,減少對外來水的依賴。我們對此計畫抱著高度期望。」
節水回收 增進管線效率
WaterSMART由聯邦政府內政部開墾局資助,將在12州推動64個子計畫。開墾局官員Estevan López表示,「我們建議加州政府推動實施任何可以紓解旱災的節水方案。同時應用聯邦資金提升水回收再利用的效能,為加州環境與民眾創造雙贏。」
開墾局現正針對西部12州推動50個子計畫,總金額超過2千4百萬美元,還有提供加州7個水資源開發與再造計畫,總額約2千3百萬美元。還有約2百萬資助加州與德州的水資源相關研究計畫。
未來,開墾局還將提供1百萬美元交由加州Fresno市執行幾項大計畫。例如:名為「Friant-Kern Pipeline」的水道工程計畫,建設直徑60英吋、長7.4公里的水道結構調整,以連結Fresno市東北方的汙水處理廠,總計約1千7百多萬。
新的管線規劃可讓Fresno市繞過75.6公里的現有水圳,提升管線效率、減少蒸散量,估計每年可省下4,050英畝英尺的水資源。不過,接下來2-3年,此50項子計畫一半費用需仰賴聯邦政府以外的資源支持。
水資源保育長期計畫 約380萬人受益
加州7項計畫執行費用達約2千3百萬美元,農工、民生用水、地表水等。開墾局提供的費用佔總經費25%,其他則由贊助單位提供。
另外,開墾局還特別提供160萬美元給地方社群調查未來再生水利用與需求的前期研究計畫。今年加州獲得4個研究贊助、德州則有3個。
WaterSMART計畫始於2010年,已提供約2億5千萬美元給原民部落、水源區、直轄市與大學等非聯邦政府管轄的機關團體。在這些資助下執行的水資源保育計畫,估計讓超過380萬人獲得充足用水。

The Obama Administration will invest nearly $50 million to improve water efficiency and conservation in California and 11 other western states squeezed by years of crippling drought, Secretary of the Interior Sally Jewell announced today.
Funded projects will replace thirsty grass with drought-tolerant plants, upgrade irrigation controls, line canals to prevent seepage, capture stormwater runoff, increase groundwater recharge and improve salmon habitat.
“In a time of exceptional drought, it is absolutely critical that states and the federal government leverage our funding resources so that we can make each drop count,” said Secretary Jewell. “Being ‘water smart’ means working together to fund sustainable water initiatives that use the best available science to improve water conservation and help water resource managers identify strategies to narrow the gap between supply and demand.”
Jewell made the funding announcement at the Donald C. Tillman Water Reclamation Plant in Van Nuys, California, where millions of gallons of wastewater are purified each day.
She was joined by Chief Sustainability and Economic Development Officer of the Los Angeles Department of Water and Power Nancy Sutley, who headed the White House Council on Environmental Quality during President Barack Obama’s first term in office.
“The federal government’s support for critical water efficiency and reuse projects is most valuable especially during this historic drought in California,” said Sutley. “The investments will help cities like Los Angeles carry out our sustainability objectives, further build our local water supply and reduce our reliance on imported water. We look forward to all these important opportunities ahead of us.”
The funding to suppport 64 projects in 12 states will come from the Interior Department’s Bureau of Reclamation through the WaterSMART Program.
Reclamation Commissioner Estevan López said, “We commend the state of California for all the steps they have already taken to alleviate the impacts of the drought. We hope this federal funding for water reuse and efficiency will help us leverage scarce resources between the state and federal governments to bring much-needed relief for the people and environment of California.”
The Bureau of Reclamation is investing more than $24 million in grants for 50 water and energy efficiency projects in 12 western states. The agency will provide more than $23 million for seven water reclamation and reuse projects in California, and nearly $2 million for seven water reclamation and reuse feasibility studies in California and Texas.
Reclamation will contribute $1 million to several projects, including the largest funded project, which will be carried out by the City of Fresno, California. The Friant-Kern Pipeline Project will install 4.6 miles of 60-inch diameter pipe and a new turn out diversion structure, connecting the Friant-Kern Canal with Fresno’s Northeast Surface Water Treatment Facility at a cost of $17.85 million.
The new pipeline will allow Fresno to bypass 47 miles of lined and unlined open channel canals that are now used to deliver water to the Treatment Facility. The project will reduce seepage and is expected to result in annual water savings of 4,050 acre-feet. Conserved water will be delivered to the Treatment Facility, where it will be treated, then delivered to meet domestic, potable water demands in the City of Fresno.
The 50 projects announced today will be leveraged with at least 50 percent non-federal funding for a total of $133 million in improvements over the next two to three years.
For a complete description of the 50 projects, visit the WaterSMART Water and Energy Efficiency Grantwebsite.
Seven projects in California will receive $23.2 million to reclaim and reuse municipal, industrial, domestic or agricultural wastewater and naturally impaired ground or surface waters.
The Bureau of Reclamation provides up to 25 percent of project costs. Project sponsors provide the remaining 75 percent.
For a complete description of these seven water reuse projects, please visit theWaterSMART Title XVI website.
Reclamation is providing $1.6 million for communities to study whether water reuse projects would help them to meet their future water needs.
Four feasibility studies in California and three studies in Texas were selected this year. Feasibility studies are funded jointly by Reclamation and project sponsors. A cost-share of at least 50 percent of study is required.
A complete description of the seven new studies selected for funding are online at the WaterSMART Title XVI website.
Since it was established in 2010, WaterSMART has provided about $250 million in competitively-awarded funding to non-federal partners, including tribes, water districts, municipalities and universities. The agency says these investments have conserved enough water to meet the needs of more than 3.8 million people.
