Reliable subsurface drainage systems for groundwater table and salinity control are needed to
maintain or enhance the productivity of irrigated lands and to contribute to the rural development
of lowlands in the humid tropics.
The purpose of this Paper is to provide this practical information to drainage engineers and
contractors. This Paper is based on the current knowledge of water flow into drainpipes and
envelopes, their properties and applicability.
