    Pipe Drainage an overview ScienceDirect Topics

    One solution for Pittong has been to install a pipe drain at 1.0 m depth down the affected hillslope area and to connect a lateral pipe drain directly from the seepage area. Effectively, this diverts both the saline groundwater seepage and the throughflow into the pipe system, reducing surface discharge of groundwater and reducing waterlogging on the slope.
