향후 25년의 물공급 안정성을 유지하는 방안에 대한 개요를 나타낸 서던캘리포니아(Southern California)의 장기 수자원계획이 주 전역을 덮친 기록적인 가뭄과 이용가능한 물공급 변동성이 증가한 가운데 도심수자원구역 이사회에 의해 업데이트됐다.

수자원국의 업데이트된 2015 통합 수자원계획인 ‘오늘날 수자원 핵심 포인트(Key points of Water Tomorrow)’는 잠재적인 물부족으로부터 지역을 보호하기 위한 향후 투자 자원을 확인하는 내용을 담고 있다.

 

 

 

Southern California’s long-term water resource plan that outlines ways to maintain supply reliability for the next 25 years was updated today by Metropolitan Water District’s Board of Directors in the midst of a record statewide drought and increased volatility in the available supplies for the region.

 

Key points of Water Tomorrow, Metropolitan’s updated 2015 Integrated Resources Plan, include identifying resources for future investment to protect the region from potential water shortages. The plan also emphasizes lowering demands through conservation and other actions as well as the need for developing new supplies through more local projects like water recycling.

 

“The updated plan offers an evolving roadmap for maintaining regional water supply reliability through 2040,” said Metropolitan board Chairman Randy Record. “It provides the vision for Metropolitan’s strategy to ensure future supply reliability by adaptively managing through change.”

 

Metropolitan General Manager Jeffrey Kightlinger said action and additional investment are essential to ensure water reliability for the Southland’s future.

 

“One of the major findings of the 2015 plan update is that, without further regional investment, supply reliability could significantly degrade to the point where the Southland could face mandatory cutbacks in eight of every 10 years by 2040,” he said.

 

The updated plan builds on the strong foundation of diversification and adaptation fostered in Metropolitan’s inaugural IRP in 1996 and through subsequent updates in 2004 and 2010, Kightlinger added.

 

“The key to managing risk and future uncertainty is through an adaptive management strategy that stabilizes and maintains the region’s imported supplies through the State Water Project and Colorado River Aqueduct, builds on our successful conservation ethic, and sustains and develops new local supplies,” Kightlinger said.

 

“We also need to pursue water transfers and exchanges, increase storage to manage drought, and look at other supply actions,” he said.

 

Today’s decision follows nearly a year of comprehensive technical analysis of regional supply reliability through 2040, while also identifying reliability targets for conservation and local supplies.

 

Along the Colorado River, the success of Metropolitan’s partnerships and land management programs, including the fallowing program in the Palo Verde Valley which makes conserved water available to urban areas, points to the potential of new collaborations to maximize river supplies, particularly during dry years.

 

The plan’s goal for State Water Project supplies is a wide-ranging strategy that would effectively manage water flow and export regulations in the near term and achieve a long-term solution to the ecosystem and water supply reliability issues in the Sacramento-San Joaquin Delta. Completion of California WaterFix would create the infrastructure needed to move additional supplies in wet years.

 

While Metropolitan and its 26 member public agencies focus on California’s goal to lower residential per-capita water use 20 percent by the year 2020, the Water Tomorrow plan emphasizes increased outdoor water-use efficiency to achieve greater savings, largely through the region’s compliance with the state’s Model Water Efficient Landscape Ordinance.

 

Following today’s adoption of the 2015 update, Kightlinger said there are remaining policy discussions that will be critical to guiding the development and maintenance of local supplies and conservation.

 

“Over time, we will begin policy discussions that will be led by the board and our member public agencies to address a variety of questions, including how to meet regional reliability targets, what constitutes local and regional responsibilities and how to finance regional projects,” Kightlinger said.
