Well Re-Casing

We specialize in well re-casing for the residential and commercial sector. Many wells located in the great valley have steel casings with no annular seal. As the casing ages it rusts and holes can develop and, in many cases, lead to a contaminated well. We recommend having your well tested for Coliform Bacteria and E. Coli. Bacteria once a year. If your well water has changed colors after a heavy rain fall that is a sign that the casing may have holes.

We begin the job by placing a camera down the well to determine several aspects of the well (i.e. casing depth, well depth, and geological formations). All recordings are captured on a hard drive then put on a DVD for the owner's records. We use PVC F480 casing and install it inside of the steel casing. We use a packer at the bottom of the new casing and place the new casing below the existing casing. We pump cement above the packer to anchor the new casing. The remaining portion of the annular seal is either cement or bentnight, depending on application and code. 

Well Rehabilitation

Over time a well can get build ups of sediment, sand, iron scaling, bacteria, and more, all of which can reduce the performance of a well--especially if the casing has perforations. Furthermore, sand can harbor bacteria in between the grains.

We use a few methods to clean and re-condition water wells. We develop a well using the air lift method to blow out any sand, sediment, or casing debris. This method consists of using a trailer mounted air compressor and injecting high volumes of air and pressure down the well. In conjunction, we sometimes will use a large diameter brush to clean the side of the casing and clean any perforations.
