This project will restore the Main Avenue and Madrone pipelines to full operating capacity of conveying 10 cubic feet per second (cfs) and 27 cfs, respectively, for a total of 37 cfs from Anderson Reservoir or the Santa Clara Conduit for groundwater recharge via the Main Avenue Recharge Ponds and the Madrone Channel. The project will plan, design, and construct approximately 14,000 linear feet or 2.6 miles of 30-inch to 36-inch diameter pipeline and associated appurtenances.
Valley Water began construction on this project January 2018. In January 2019, Valley Water completed major construction along Cochrane Road from the Anderson Dam outfall to Half Road and along Half Road from Cochrane Road to the Madrone Channel, which included trenching, installation of pipes, backfilling the trenches and repaving the roads. Crews may be observed on Cochrane Road and Half Road performing minor facility, site restoration and quality check work. Major construction work will continue on the remaining section of Cochrane Road and East Main Avenue and is scheduled to be completed in June 2019.
What to expect during construction
Construction hours will be from 7 a.m. to 5 p.m. Monday through Friday.
Public access to residential and commercial properties will be maintained when possible throughout this phase of construction, but anticipate minor delays, pedestrian detours, intermittent road closures, noise and other minor impacts. When possible, Diana Avenue, Peet Road, Mission View Drive, and Condit Road should be used to bypass construction on Cochrane Road and East Main Avenue.

Key Performance Indicators for the Safe, Clean Water Program
Restore transmission pipelines to full operating capacity of 37 cfs from Anderson Reservoir.
Restore ability to deliver 20 cfs to Madrone Channel.
Increases groundwater recharge by about 2,000 acre-feet per year in South County’s Llagas Groundwater Sub-basin, a sufficient water supply for 4,000 families of 5.
Improves operational flexibility.
Maximizes the delivery of imported water to treatment plants supplying drinking water to North County.
Saves energy, reduces operating costs, and cuts CO2 emissions by reducing dependence on Coyote Pumping Plant.

About the Safe, Clean Water and Natural Flood Protection Program
In November 2012 the voters of Santa Clara County overwhelmingly approved Measure B, the Safe, Clean Water and Natural Flood Protection Program, as a countywide special parcel tax for 15 years with a sunset date of June 30, 2028. This Program replaced the Clean, Safe Creeks and Natural Flood Protection Plan, which voters approved in November 2000.
The Safe, Clean Water Program was developed with input from more than 16,000 residents and stakeholders and was created to match the community’s needs and values. The voters of Santa Clara County identified five priorities:
Priority A: Ensure a Safe, Reliable Water Supply
Priority B: Reduce Toxins, Hazards and Contaminants in our Waterways
Priority C: Protect our Water Supply from Earthquakes and Natural Disasters
Priority D: Restore Wildlife Habitat and Provide Open Space
Priority E: Provide Flood Protection to Homes, Businesses, Schools and Highways
Other: Six projects from the Clean, Safe, Creeks Plan have been carried forward into the Safe, Clean Water Program.
Each year, Valley Water prepares a report providing a progress update for each of these Program priorities, along with fiscal year accomplishments.
To ensure transparency and accountability to the voters, the ballot measure also created an Independent Monitoring Committee, appointed by the Santa Clara Valley Water District Board of Directors. The Independent Monitoring Committee annually reviews the Program’s progress to ensure the outcomes are achieved in a cost-efficient manner and reports its findings to the Board.
In addition, the Program requires three independent audits, the first of which was conducted in FY 2017.
