Protecting groundwater

Concerned that the region is slowly using up a vast reserve of water stored beneath the San Fernando Valley, Los Angeles, Glendale and Burbank have agreed to limit the amount of groundwater they pump so the basin can refill. Kerry Cavanaugh in the Daily News.

Under the proposed agreement approved Tuesday by the L.A. Board of Water and Power Commissioners, the cities can still pump their annual allotment of groundwater - which is the cheapest water available.

But they won't use most credits that would allow the cities to draw extra water during dry years and save millions of dollars spent on purchased water.
