Comments on leachpit pourflush latrines
The strategy for leach pit pourflush latrines has been
conceived to provide on-site low-cost sanitation systems
for the poor to improve their quality of life and control
water-borne diseases. Human excreta is a reservoir of
pathogens and viruses. Indiscriminate and open defecation
is a serious pollution source affecting human health and has
thus become a great concern in the field of environmental
sanitation and public health worldwide. With time, the gap
between the growth of population and provision of sanitary
latrines appears to be divergent amongst the economically
weaker sections. Concerted efforts are being made to
close this gap, but the peoples’ response is found to be not
as strong as predicted. In the absence of low cost solutions,
both in construction and maintenance, the sanitation approach
to the community will be ineffective. Thus the
choice of leachpit latrines needs to be popularized, with
remedial measures for its short-comings, as contemplated
and presented in this text
Hydrophytes in municipal wastewater treatment and limitation
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
