Report a Spill or Dumping

Zone 7 owns many flood control channels and creeks in the Cities of Livermore, Pleasanton and Dublin, and in unincorporated areas of Eastern Alameda County. If you see a spill or dumping in any waterway, follow the directions below to report it:
  1. If a spill is currently happening, call 911.
  2. If the situation is not urgent, call:
  • Zone 7 Administrative offices at (925) 454-5000 during business hours, Monday-Friday, 8 a.m. to 5 p.m.
  • Water Treatment Plant Operator at (925) 447-6704, ext. 1, during non-business hours

Zone 7 Proclaims Support for
and Participation in
California Flood Preparedness Week

On Wednesday, September 21, 2016 the Zone 7 Board of Directors announced Zone 7’s support for and participation in the fifth annual California Flood Preparedness Week (2016) to be held October 24-29. Along with the California Department of Water Resources, Federal Emergency Management Agency, US Army Corps of Engineers, NOAA National Weather Service, County of Sacramento, and FloodSAFE California, Zone 7 Water Agency is continuing to support a statewide effort to educate the public about the dangers of flooding, how to prepare their homes and families for a flood, and plan for recovery.

Zone 7 Takes Next Step to Study
Advanced Recycling Options 

As a next step toward enhancing long-term water supply reliability for the Livermore-Amador Valley, the Zone 7 Board of Directors approved funding on Wednesday evening for a study by Carollo Engineers to evaluate the feasibility of advanced water recycling. The feasibility study will be a joint effort by the Tri-Valley water agencies and will evaluate the feasibility of various advanced water recycling options for the Valley; identify the most promising options based on technical, financial, and regulatory considerations; and, assuming that such advanced water recycling is found to be both technically and economically feasible, recommend next steps for the agencies.

Options for using highly-treated wastewater (recycled water that has also been processed through both reverse osmosis and advanced disinfection) include groundwater recharge (either injection or surface water recharge possibly using the Chain of Lakes), surface water augmentation, or blending and connection upstream of surface water treatment plants for additional treatment. Direct potable reuse (connecting the treated wastewater system to the water transmission system) is not being considered at this time based on input from the Tri-Valley’s elected representatives at a February 2016 Water Liaison Committee meeting and, again, at a September 22, 2016 Water Liaison Committee meeting. The study is expected to kick-off in late October 2016 and should be completed by the end of 2017. The findings and recommendations from the study will be presented to the governing bodies of the Tri-Valley water agencies for their consideration and potential actions.

Zone 7 Invests
in Reservoir Expansion Studies

The Board approved approximately $210,000 for Zone 7 to participate in two reservoir expansion studies aimed at diversifying storage options for the agency. As part of a collaboration with the other two South Bay Contractors (Alameda County Water District and Santa Clara Valley Water District), up to $75,000 would be invested in evaluating the feasibility of increasing storage capacity in Lake Del Valle through optimized reservoir operation and/or physical modifications to the facilities. Lake Del Valle is the only State Water Project storage facility on the South Bay Aqueduct, providing emergency reserves in the case of aqueduct failure. The reservoir is also used for Valley flood protection and to collect a small amount of local runoff.

The second storage study that was approved this week was participation in a Los Vaqueros Reservoir study with about eight other partners. Approximately $100,000 plus another $35,000 of in-kind services from Zone 7 staff will go towards environmental assessments, engineering and technical studies to determine the costs and benefits of expanding Los Vaqueros Reservoir and the possible construction of a pipeline to connect the reservoir to the South Bay Aqueduct system. The results of the study will also allow Los Vaqueros Reservoir Expansion Project to potentially qualify for funding from Proposition 1, the 2014 water bond. The added capacity and connectivity to the regional delivery systems potentially resulting from this effort could reduce the risk of water supply shortage to Zone 7 and facilitate a regional desalination project.

Both efforts will be funded through Zone 7’s Fund 310, Water Supply and Reliability Fund, which funds future water storage and Delta-related projects. Zone 7 has also approved participating in Phase 1 of the Sites Reservoir Project, which could potentially provide both water supply and water storage benefits. Sites Reservoir would be a new, offstream reservoir with 1.3-1.8 million acre feet of new storage capacity with a large portion earmarked for environmental water. In July of 2016, Zone 7 submitted a “Proposal to Participate” requesting a participation level of 20,000 acre feet.
