Water shortage points out tough choices

Recent news that this winter's heavy rains have not completely recharged valued underground aquifers was not completely unexpected.

Water managers routinely remind us that a few days of heavy rain, particularly following dry conditions, is no reason to forget about conserving water. That's because much of the rain ends up as runoff from bone-dry land. It doesn't get underground.

Still, the story is a reminder of a larger public policy issue that is not being discussed as much as it should. It is becoming increasingly obvious that our fresh-water supply is not infinitely sustainable.

There will come a time when no amount of rainfall will be able to compensate for increased use.

This is important as the state — particularly O'ahu — looks to what promises to be a substantial housing boom.

Thousands of new civilian homes are being projected, particularly in the Leeward and Central areas of the island. In addition, the military has a big housing construction program of its own tap.

All these homes, and the people in them, will have a demand for water. Will we be able to keep up with the demand?

The water boards in the various counties have in place a variety of programs, ranging from conservation to resource development, that help keep ahead of the curve. Every bit helps.

Eventually, policy-makers will be forced to make calls about how much development, how much demand on water resources, is sustainable. Are there reasonable, affordable alternatives to the groundwater we depend on today?

The time to begin thinking of such matters is now. The latest advice from water officials is just another timely reminder.
