In the summer season, every living being needs water to quench the thirst which is so often felt again and again during the day and night. People even feel the need of water while they are sleeping and head towards their refrigerators to find a bottle of cold water to quench their thirst. This huge spike in the water consumption graph is a huge challenge for the authorities who have to prepare in advance to provide their cities with abundant water flow. Hence the spring time is the busiest for the water management authorities who are not only focused on cleaning the pies and tanks, but are also replacing the old and worn out liquid level indicator to avoid any mishap in the summer season.

The clean water flowing in the taps is a blessing for the people who live in developed cities. But this water which appears out of nowhere as soon as the knob is turned is not the work of a magician, but it is due to the untiring work done by the water treatment and supply authorities in the back end. It all starts from the small duct present in the stream of a drain which passes the dirty water from all over the city. The authorizes have total control over the duct’s opening and closing of the lid which allows them to operate it from their control rooms and let the water fall inside the pipe of the duct which leads it all the way to the water treatment and filtration plant.

As soon as the need for more water is felt, the duct is opened and the drain’s water starts entering the duct and into the huge water tank in the treatment plant. As soon as the drain’s water fills the water tank, it is then opened towards the huge filters from where the water is allowed to flow and the filters keep the leaves and stones present in the dirty water to pass on. Hence the first stage of filtration has started and as soon as the water passes through the first set of filters, the second ones are even smaller nets which let the water pass on but takes away the dirt from it.

Now the water is filled in a water tank and using the ultrasonic level indicator, the water level is noted which gives the staff an idea about how much dirt has been removed from it. After measuring the water, a sample is taken to the laboratory and the bacteria present in it are identified. Reading the results, the amount of chlorine is added to the tank which makes the water safe for drinking but has some chlorine present in it. Removing the extra chlorine would make it completely fit for human use and that is exactly what is done. The water is passed through the final filters which remove the chlorine and the once discarded water is again transported to the taps of the homes and all other taps present in the city.
