Regional Groundwater Storage

Project Details

The concept of groundwater storage and recovery consists of storing water in wet years and recovering that water for use during dry years. As part of the RGSR project, surface water will be used instead of groundwater in wet years, allowing the groundwater to recharge through rainfall and decreased pumping. This will create a savings account of up to 20 billion gallons of groundwater that will be stored in the aquifer.

SFPUC contracted Ranger Pipelines to drill, install and construct 13 groundwater well facilities including site prep; clearing/grubbing and grading; various work on existing groundwater wells; 8 well building construction including foundations, temporary shoring and retaining walls; new pumps, motors, chemical injection systems and related appurtenances; ventilation system; trenching and pipeline and conduit construction; cathodic protection system; chemical treatment equipment, tanks and pumping systems; electrical power distribution systems, SCADA and I&C control systems; perimeter security fence; security monitoring and control systems; final grading and drainage, landscape and irrigation systems; sanitary and storm drain piping and connections to municipal systems; 7,000LF of 8″ and 12″ diameter (DIP) ductile iron water transmission pipeline.
