Almost fifty yers ago we visited a waste water treatment system in San Diego County that achieved tertiary treatment by directing the effluent through a series of ponds and wetlands to end up with drinking water quality. Now, we read that the LA water district is considering recycling instead of dumping treated water into the ocean. The estimated cost is a mere $50 BILLION. We need to remember to compare that to the $70 Billion we spend on lottery tickets every year to make the point that we shoukd not be basing decisions on anticipated costs. Avoided disease and drought are not quantifiable.
