Study: California will need 40 percent more water in 25 years

Don Thompson:

California's thirst for water will jump by 40 percent over the next 25 years at current rates, with much of the water going for landscaping in the hot, dry inland valleys that will see the bulk of the population growth, warns a study being released Wednesday.

The nonpartisan, nonprofit Public Policy Institute of California plotted future use from current water consumption, population growth estimates and demographic projections. Fourteen million more people will each be using 232 gallons each day by 2030, at the current pace.

But the institute says conservation, water planning and recycling can help meet the demand as the West struggles with continuous water shortages.

The institute found that a 2001 state law is working well, requiring that housing developers demonstrate in advance that they have lined up enough water for new residents before they start building homes.

Yet one-sixth of large municipal water utilities failed to submit water plans when last required five years ago, and other plans lacked adequate supply and demand projections. A Senate-approved bill pending in the Assembly would increase reporting requirements.

California already has made strides in cutting indoor water use with more stringent plumbing codes and requiring water-efficient appliances.

Outside, however, a lot of water goes to keep suburban lawns green.

And with half of all the state's projected new residents moving to Sacramento, San Joaquin and western San Bernardino and Riverside counties east of Los Angeles, that use will increase dramatically.

Of course, the most effective way to deal with the water situation is to limit population growth and the most effective way of doing that is by limiting immigration.

What has happened to California in the last few decades is really a modern American tragedy.
