Off-site wastewater treatment at low cost is a burning
issue in developing countries. Use of water hyacinth and
duckweed have been tried world wide and the findings of
its efficiency have been found promising. The concept has
become old but the work with duckweed is still continuing
at different levels. Time has come to arrive at a conclusive
policy/decision to the extent this water hyacinth (Eichhorina
crassipes) or duckweed (Lemna) may be utilised. The
guidelines in respect of the design parameter and Operation
– Maintenance schedule should be available to the
community. For the strategy of wide scale success of such
system the involvement of NGO’s and community
participantion should be inducted from the initial stage.
Different aspects have been discussed in the text to arrive
at a conclusion upto what extent and at what level the
system of hydrophyte based waste-water treatment will
have wider use by the community.
