Flood Relief:clean drinking water and PCSIR products

Water gets contaminated in the flooded environment.And the victims are usually out of their homes without any pots and stoves and fuel to be able to boil their water.Disaster aid agencies and NGOs are often asking for donations of water cleaning kits that are imported usually and its supply uncertain.There are several solutions that may be implemented by the agencies:

Household bleach is one of the best disinfectant,approved by such donor agencies as DFID.A few drops per liter and 30 minutes waiting time does an excellent job.NGOs and volunteers should make these supplies available to the flood victims and do some demo and ax plaining.This practice can even be adopted as a routine as well

Another good disinfectant,quite effective and safe,was developed by our PCSIR. It was a pouch containing sand and silver halide.All one was require to do was to put such a pouch in ones water pot or filter ,and drink safe water out of the tap.the product was developed probably in late 80's and was quite visible.Several of my friends and relatives did use it for quite some years when I was weaned on mineral water which i have stopped and have returned to the boiled water at my home.I wonder what happened to the PCSIR product.It is no more visible.It could have proved very handy for the flood victims.Why was it discontinued? May be due to lack of enough demand or having been proved undesirable for some scientific reason.Only PCSIR can tell ? We would like to listen if they are listening us.

Five Reverse Osmosis(RO) plants and three ultra-filtration plants designed and manufactured by EME Karachi garrison of Pakistan Army were dispatched today to various locations in Sindh.Ultra-filtration plants have a capacity of 25,000 liters a day and cost Rs.50,000/- per,while R.O.plants have a capacity of12000 liters a day and a price tag of Rs. 2.5 million.Naturally ROs are quite expensive as the water quality is almost mineral water irrespective of the input quality.We have earlier discussed the case of procuring such plants on rent or lease or outright purchase of even used plants.Some areas permanently require ROs or ultra-filtration plants where these can be dispatched to after the emergency.It is a good idea on the part of EME of Pak Army to have engaged in this kind of endeavor which would have multiple benefits.
