Davis is no exception to the California tradition of putting off difficult water decisions to get by as problems worsen and become more expensive. Since the 1950s building of Lake Berryessa, Davis has passed up promising but inconvenient long-term water supply solutions, and now finds that expenses have grown and are likely to worsen.
Davis’ groundwater supply is becoming less secure. Relatively exhaustive examinations of supply alternatives in recent years, done by different groups over time, have come to similar conclusions: Today, the least expensive sustainable solution is to combine with Woodland on a joint water supply.
This will be expensive, but deferring a good solution now seems likely to leave us with more expensive solutions later.
