A representative of Slipper Rock Ranch attended a community meeting about water concerns.
The Goleta Water District is suing the ranch over its use of well water. The trial began last week.
One of the ranch owners is "Law & Order" creator Dick Wolf.
Ranch neighbors have accused him of trucking water to another property he owns in Montecito and selling it to others.
Ranch spokesperson Cory Black said the accusations aren't true.
Black said the lawsuit is about water rights.
"The ranch is outside the boundaries of the Goleta Water District and also outside the boundaries of the water basin," said Black. He said the district has spent $3 million on this case and may have to pick up legal fees.
But neighbors including Helen Larsen are confident the district will win the case.
"I want them to be aware of the fact that there are other people on the aquifer. I do not want them to be taking out more water that is there share," said Larsen.
Neighbors who live in the foothills above Goleta are worried they will have to foot the bill for another well if their water supply runs out.
