Most of us focus primarily on the purification of the water that we drink or use for cooking purpose. But we rarely pay attention on cleaning of the water tank where water is stored. Every day we use the tank water for brushing and bathing, for cleaning and moping, for washing clothes and in other household works.With the passage of time, sediments, scale and algae get deposited on the walls, ceiling and floor of the water tank. This deposition contaminates the water and makes it unfit for use. With time algae and bacteria grow and breed in this water, infect it and could make us fall sick eventually. It simply means that our ignorance towards water tank cleaning may take a toll on the health of our family. WATER TANK CLEANING SERVICE Tank cleaning is very necessary and should be done at least once in a year. But it also depend on the quality of water supplied into homes. If the water is very hard and high in TDS, then sedimentation will happen more often. In such cases more than one annual water tank cleaning is required.
