The recent floods have played havocs with the lives of million of people. Food and clean drinking water are the two urgent requirements for those who are displaced and living in the flood affected areas.

According to the spokesman for the UN Office for the Coordination of Humanitarian Affairs in Islamabad, around 1.5 million people are treated for everything from respiratory and skin infections to diarrhea.

Majority of health patients are suffering from waterborne diseases gastro, diarrhoea, dysentery, typhoid, and cholera.

All these deadly diseases are appearing because of consumption of contaminated water by people. Supply of clean drinking water in a large scale is not possible and a costly venture which cash-starved government of Pakistan can afford.

However, there is a cost-effective substitute to ensure clean drinking water to the people. Hygienic Filter Water Pipe

This pipe cost Rs150 with different construction inside can purify turbid dirty water for human consumption. This type of pipe can be constructed easily in the country.

It is a 25 cm long, 29 mm diameter, plastic pipe filter. The pipe can provide viable means of saving tens of millions of lives from the deadliest waterborne diseases.

Hygienic filter water pipe is water purifier tool with a lifetime of 700 liters approximately one year of water consumption for one person, two years for a child. Positive test results have been achieved on tap, turbid and saline water against common waterborne bacteria such as Salmonella, Shigella, Enterococcus and Staphylococcu.

The remarkable potential of the hygienic water filter pipe is that it does not need electricity but sucking power of the user kills diseases.

Hygienic water filter pipe, the lightweight, 12.2 inch (25cm) device can be carried or worn around the neck and filters a minimum 700 liters of water and requires no electricity or spare parts for the duration of its life. It provides protection from common diarrhea diseases, removing particles down to 15 microns and killing and removing 99.999 per cent of waterborne bacteria plus 98.7 per cent of waterborne viruses.

By using hygienic pipe, the levels of bacteria in the water are reduced to the levels that provide safe water for human consumption. 'Safe' implies water from which any health risk is minimal. The particulate removal suggests that the number of any parasitic ova in raw water is also reduced significantly. The released amount of iodine in water treated from hygienic water filter pipe is not normally damaging to human health. However, people having thyroid problems and allergic reaction to iodine must seek medical advice before using this tool.

DESIGN

The hygienic water filter pipe personal is a plastic tube of 31 centimeters long and 30 millimeters in diameter. Water that is sucked through the straw first passes through a mesh of 100-micrometer spaces, then through a mesh of 15-micrometer spaces. Water then passes through a chamber with iodine-coated beads killing remaining bacteria. The water passes through an empty chamber, and then finally passes through active carbon, removing the iodide taste and medium-sized bacteria. The entire process is powered by suction, similar to using a conventional drinking straw, and filters up to 700 liters of water.

BASIC FEATURES OF HYGIENIC WATER FILTER PIPE

* Offers easy access to safe drinking water away from home

* Filters a minimum of 700 liters of water

* Kills and removes 99.999 per cent of waterborne bacteria

* Kills and removes 99 per cent of waterborne viruses

* Removes particles down to 15 microns

* Requires no electrical power or spare parts for the life time of the straw

* Easy to mass distribute in areas where drinking water is contaminated

People with little amount can start production of hygienic water pipe since it is a technology that can be localised completely. Technology is simple and which based is on three materials.
