Since 2002, California authorized more than $17 billion in general obligation bonds to fund water-related projects. These funds are disseminated via competitive solicitations. Some of the funds are issued as grants, some as low interest loans (in certain cases, such as for eligible Disadvantaged Communities, loans may be converted to grants).

Water-Related General Obligation Bonds Amount
Parks, Environment, and Water Bond (June 2018)[1] $1.27 billion
The Water Quality, Supply, and Infrastructure Improvement Act of 2014 (Proposition 1) $7.12 billion
The Safe Drinking Water, Water Quality and Supply, Flood Control, River and Coastal Protection Bond Act of 2006 (Proposition 84) $5.4 billion
The Water Security, Clean Drinking Water, Coastal and

Beach Protection Act of 2002 (Proposition 50)

  • That amount does not include the $4 billion for The Disaster Preparedness and Flood Protection Bond Act of 2006 (Proposition 1E) that provides some water supply benefits through plans and structures that divert flood waters to groundwater recharge basins.

    Approved uses of these funds encompassed a diversity of water-related concerns: public water system improvements, surface and groundwater storage, drinking water protection, water recycling and advanced water treatment, water supply management, and conveyance, stormwater management, wastewater treatment, ecosystem and watershed protection and restoration, and drought emergency relief.
