Some customers in Sullivan County Public Water Supply District 1 will be without water today, and under a boil advisory once pressure comes back. Officials will shut off water south of Green Castle on Route FF to Port Rd. This includes customers on Iris Drive, Indian Drive and Port Road. The shutoff will happen about 8am today and last until 5pm. Because of the loss in pressure, residents of that portion of the system will be under a boil water advisory until noon Friday.
