California Cities Develop Surface Water Supply To Reduce Dependence on Groundwater

摘要

Woodland and davis are among the largest of the municipalities in northern California that rely exclusively on groundwater to meet their drinking water needs. Faced with declining ground-water quality and increasingly stringent discharge requirements, the two cities have long been working together to develop a reliable source of surface water. In mid-October the efforts of the two cities came to fruition when the Woodland-Davis Clean Water Agency-the entity formed for the purpose of developing the new surface water source- awarded a $141.2-million contract to CH2M HILL, of Englewood, Colorado, to design, build, and operate a surface water treatment system that will rely on water from the Sacramento River.
