The City of Amarillo, Texas has been using Boreline by Hose Solutions since 2010 in its potable water wells. It is a great product to use for work in tight applications where you cannot get a rig in. Our first time to use it was in a well about 600’ deep. Boreline also allows you an energy cost saving over time because it maintains its smooth wall vs the corrosion aspect of steel pipe. Very simple product to use. It has a NSF rating.
