Basically Union Co. buys water from Lancaster County, SC. I read this in the Lancaster paper a couple of times when water restrictions was in the news for both counties.
I found this short description on Lancaster's water and sewer page.
Lancaster Water and Sewer District - About Us
I wonder if there's a difference in what a Lancaster and Union resident pays for water. It costs me about $30 for 3,000 gallons of water and $20 for 3,000 gallons of sewer service. Can anyone comment? Do some areas of Lancaster or Union have better or worse service?
I live in the Indian Land area of Lancaster, not far from the state line. I have high speed internet. I'm sure large areas of Union have access to high speed internet through Time Warner Cable and maybe even DSL providers. I see Time Warner and Windstream trucks all the time.
Hope this helps.
