Backing water-reuse preferred over desal in Singapore

"SMART money prefers backing water-reuse projects over desalination ones, says a study done jointly by Singapore and foreign consultants.

This is because it is cheaper to purify the outfall from water reclamation plants than to turn sea water into drinking water."

Makes sense to me and something that transfers well to California. Think about the massive amounts of energy that we use to move water around the state coupled with the amount of energy that wastewater treatment plants use to cleanse it to secondary or tertiary standards. Why throw all of the energy down the drain or ocean outfall? Take a few more steps and add it back to our water supply. After conservation (think irrigation) I believe IPR is most vital for the future water supply.
