This is a reverse osmosis plant that has been there for many years. It has grown and has been expanded over the years. Yes, it effects your property in value in terms of possibly being an eyesore. I have not found the smell to be a problem in that area unless you are actually AT the plant. There is the ambient sound of humming machinery, though they have done a good job if minimizing that. I found homes to be a little more difficult to sell there, though if priced well, folks will overlook certain things like that plant. How much is your view worth? This is a "clean water" plant. It's purpose to take water from the underground aquifer, and convert it into drinkable water.
