Creating comprehensive drainage scheme

The poor performance of surface and subsurface drainage systems is often caused by the mediocre technical quality of drainage networks, improper drainage design and, sometimes, insuffieint involvement of farmers. During and after the installation of such systems, problems can occur owing to the lack of materials, machinery breakdowns and lack of trained staff.
