How To Keep Water Storage Areas Clean For Good Health.
Let’s consider the first possibility where a water tank continues to receive clean water, there is no dirt or sand but still continuous water storage causes the growth of algae. Algae growth should be particularly taken care of from day 1. Use chlorine(bleach) that is readily available in markets or use chlorine tablets according to manufacturer recommendation that will protect from algae and give bacteria free water.
Now lets point out another possibility which is common in Karachi and Lahore that the source of water is not clean with presence of mud, bacteria and other contaminants, then it is recommended to maintain scheduled cleaning of your water storage tank. In areas like DHA and Clifton, there is water shortage and almost 90% of water comes from tanker services which is unprocessed and extremely muddy. In these areas scheduled water tank cleaning should be conducted monthly or quarterly basis, or depending on the water usage.
Because of the ill-maintained water supply lines in Karachi, even the water coming directly from filter plants is not safe for health. There is a mixture of contaminants from sewage lines and surrounding. As a general practice, we must avail water tank cleaning services after every six months. This applies to chlorine treated tanks too as bacteria production in our underground or overhead tanks is much speedy and need timely attention
