Water Rates $ $$ $$$ $$$$ Colorado River State Water Spot Water p Loss of Sales Water Project Transfers (Shortage) <2003 2003-2007 2008> Now Supply challenges make securing water more expensive Shift to more-expensive supplies is driving up the cost of water from MWD, the Water Authority’s largest supplier Water Authority passes increased costs to member agencies Member (retail) agencies pass costs to ratepayers Lower sales increasing unit cost ($/af) of water 24

Impacts on Supply Reliability By disguising true cost of i f imported water, t d t MWD discourages local supply development Disincentive to pursuing conservation and local supply projects Disincentive to transfers that require use of MWD’s facilities Desalination membranes These kinds of projects help protect region from supply shortages 40
