These carbon steel casing pipes are often the best choice for use in unconsolidated sand and gravel aquifers. They are constructed by winding and attached with a triangular strand of wire around a set of vertical rods. The triangular design is used with the flat face towards the aquifer and the triangular face towards the pump. This design allows small particles to pass completely through the screen without becoming wedged in and clogging the screen.
