Understanding Northern China's Water CrisisJulian Wong
Northern China faces a serious water crisis as the region accounts for a large portion of China's population, GDP, and agricultural production but only 19% of the country's water resources. Water scarcity is concentrated in the north, where per capita water availability is below thresholds considered water scarce. While government reforms aim to address this through improved management and conservation efforts, fragmented institutions and a lack of secure water rights have limited progress addressing northern China's critical water challenges.
Sprayed Away: Seven Ways to Reduce Texas’ Outdoor Water UseDanousis85z
Texas is the fastest growing state and faces increasing pressure on its limited water supplies. Outdoor water use, primarily for landscape irrigation, increases dramatically in the summer and accounts for about half of total municipal water usage. Implementing various conservation strategies like improving irrigation systems, incentivizing water-efficient landscaping, enacting watering ordinances, and expanding education programs could reduce outdoor water usage by 25% on average across 18 major Texas cities, saving over 147 million gallons per day. Doing so would benefit both utilities and customers by decreasing costs and better preserving water resources for the future.

2. The preferred project is a large infrastructure project to deliver water through the Delta and costs have increased to an estimated $14.9 billion.
3. There is uncertainty around supply benefits without an NCCP/HCP and around how costs will be allocated.
This document provides background information on California's efforts to address water supply issues related to the Sacramento-San Joaquin Delta and transport of State Water Project water. It summarizes the history of initiatives including CalFed and the Bay Delta Conservation Plan (BDCP). The document then outlines topics discussed at recent Metropolitan Water District board meetings regarding the BDCP/California WaterFix, including project details, costs, risks and timeline. It concludes by summarizing the key aspects and public review process for the recently released recirculated draft environmental documents.
1) The document discusses the estimated costs of the Delta conveyance facility for urban and agricultural water users in California and their capacity to pay.
2) It analyzes the potential costs to the Metropolitan Water District (MWD) under different scenarios for cost allocation between the State Water Project and Central Valley Project, ranging from $211 million to $546 million.
3) It notes that there are important financing risks still to be resolved, such as construction cost overruns, regulatory uncertainty, and whether habitat funding will be provided, that could jeopardize operating the tunnels or affect the ability to issue bonds.
1) The document discusses the financing issues around building a Delta conveyance facility, known as the BDCP.
2) It analyzes the potential costs to water contractors like MWD under different scenarios, finding their peak annual costs could range from $168 million to $378 million depending on how costs are allocated.
3) It notes a number of important financing risks still need to be resolved, including the revenue stream certainty required to issue bonds and developing credit for CVP contractors to finance their share.
This document discusses a government relations program on imported water and the Bay-Delta Conservation Plan (BDCP). It notes the competing interests in the Delta region involving water supply, ecosystem, and transportation. It outlines the Water Authority's analysis of the BDCP plan and environmental reviews over several years. Key questions are identified regarding project size, costs, water supply benefits for San Diego, and financial obligations. The Water Authority will continue engagement to ensure a cost-effective Delta solution that balances environmental and water supply needs and limits financial obligations proportionate to benefits received.
The document summarizes a presentation made to the Imported Water Committee about the Draft Implementing Agreement for the Bay Delta Conservation Plan (BDCP). The Implementing Agreement describes the roles, responsibilities, and commitments for implementing the BDCP, including regulatory assurances, funding, and governance. It is required for the BDCP to receive permits as a Natural Community Conservation Plan and is a typical agreement for a Habitat Conservation Plan. Key topics covered in the presentation include regulatory assurances, funding obligations of permittees versus state/federal entities, governance structure, and decision making. Areas for public comment on the draft agreement are identified as governance, funding, regulatory assurances, adaptive management and future modifications, and water operations decision trees.
1. The BDCP is a massive infrastructure project that will be difficult to implement and costs are likely to increase.
2. How project costs are allocated among contractors and who will ultimately pay are important issues that could significantly impact water rates.
3. The San Diego County Water Authority's region has explored additional local projects that may help address supply impacts, but would come at a cost and allow more local control compared to relying on the BDCP.
This document provides an overview and agenda for an Imported Water Committee meeting regarding review of the Bay Delta Conservation Plan (BDCP) documents. It summarizes prior board briefings on BDCP issues, the BDCP review process, the environmental review process for BDCP under CEQA and NEPA, and initial subject areas proposed for comment in a letter, such as governance, funding, economic analysis, and project risks. The staff recommendation is to authorize submitting a formal comment letter on the BDCP Draft EIR/EIS.
