Problems Associated With Plastic Water Tank in Africa

Due to our hot climate in so many African countries, the plastic tank when beaten by the sun causes the water inside to become warm. Not only that, plastic water tank made of white, yellow, Red, blue, causes a lot of problems when used. When the sun beats the plastic tank with water inside, made of the above mentioned colors it forms greenish substances called “algae”. The most badly affected are yellow, white, and Red colored tanks. This substance after growing on the inside walls of the tank peels and falls to the bottom of the plastic tanks and with help of the water volume in the tank it goes into the distribution pipe-line which many a time causes water blockages. At some places you will see green particles coming out from the tap whenever the tap is turned on. This irritating particle causes people to ask what has gone wrong. Solution for Algae growth inside the water tank: 1. Constant washing of such colored plastic tanks will reduce the growth and minimized it. 2. Painting the outer body of such colored tanks with black bituminous paint and repeating when the paint wears out. 3. Complete replacement of such colored water tanks. Arrangement is been made to inform manufacturers of such water tanks to stick to production of black colored tank only, which is not affected by algae even if ,left unwashed for two years. But I recommend that black plastic tanks should be washed at least twice a year for hygienic purposes.
