Lantana offers water delivery in Austin, Marble Falls, and the surrounding area. Furthermore, Lantana provides rainwater for thirsty lawns, wineries, and nurseries.
The Red Caboose winery is Meridian, Texas, is a good example of how rainwater harvesting is used for better grapes, fire protection, and well water conservation. Lantana does not provide this water to the winery, but appreciates the proactive efforts set forth by these folks.
