Like Bruce Gibson said, “You are going to have people punching holes in the ground like mosquitoes on a Minnesota camper.”
This may well be what happens when the Paso emergency water rule expires in August, just about the time when continued drought is likely to really rear its ugly head locally (again).
Requiring vintners who want to plant new grapes to offset the water use with the conservation of an equal amount of water just seems to make sense to me. There are multiple ways of doing it. Rainwater harvesting on ground that is not in production might be one way, as well as implementation of efforts to restrict water use in industrial and residential buildings on site.
Do you think vintners will do all this unless it is required? I doubt it, and the problem of wells drying up will just persist.
An article I wrote on the subject of rainwater harvesting appears in the current issue of nationwide Countryside and Small Stock Journal Magazine. It includes calculations of how much water can be saved provided by San Luis Obispo County’s Office of Appropriate Technology. Go to http://www.countrysidemag.com
