Community Water Treatment, Purification and Filtration Plants
Community Water Purification Plants
In the past few years, water borne diseases have assumed alarming
proportions. Major portion of people falling victim to these stomach,
blood and liver ailments are children mainly through consuming water
that does not meet the requisite hygiene standards. Aging and
neglected water pipelines passing through sewage drains, leakages
created in them due to corrosion, vacuums, unauthorized connections
and contamination of sub surface water with fertilisers, pathogens and
faecal material are health hazards. In addition there has been a
consistent salting of the aquifers resulting in brackish water of
varying degrees, unfit for human consumption. Our research indicates
that most of the water filtration plants installed in various
municipalities in Pakistan are not designed for optimum efficiency.
These designs are only suitable for already treated public water
supplies that pass through fool proof lines and are safe from cross
contaminations. By the time the water reaches the users, it again
develops various contaminations like bacteria, micro organisms, lead
etc. Some of the main sources of contamination are: -
·
Cross contamination
through pipelines
·
Untreated water
·
Deficient designs of
water treatment plants
·
Presence of harmful
elements/compounds like Arsenic in the entire central and
southern Punjab including cities like Lahore, Multan, Rahim Yar
Khan, Sukker etc.
·
Presence of nitrates and
nitrites along with coli forms in Rawalpindi/Islamabad and many
other areas of Pakistan.
·
Absence of effective
regulatory boards.
