Body
SUMMARY:
Project Background
The Main Avenue and Madrone Pipeline system conveyance capacity has deteriorated during the past 60 years, due to excess leakage and invasive tree roots. During the last 20 years, temporary fixes have been implemented, but the condition of the pipelines continues to degrade. In addition, Water Resources Planning Studies conducted in 2005 and 2010 have shown that there could be water supply shortages ranging from 4,000 acre-feet per year (AFY) to 16,000 AFY by the year 2030 in the South Santa Clara County, including the Llagas groundwater subbasin.
The scope of the proposed Project is to design and construct approximately 14,000 linear feet of 30 and 36-inch diameter raw water pipeline and appurtenances to replace the existing pipelines with larger diameter pipelines, restore the system to its full operating capacity, and address the potential water supply shortages. This allows for groundwater recharge via the Main Avenue Recharge Ponds and the Madrone Channel from Anderson Reservoir or the Santa Clara Conduit. Completion of the Project will address current and future groundwater recharge demands.
