Living in Kolkata, but confused, Which is the best water purifier for Kolkata Municipal Corporation’s water in November 2024?
Let’s first understand what are the water sources of KMC for City Supply.
What is the water source of the Kolkata Municipal Corporation
The river Hoogly is the main source of water supply for Kolkata.
After drawing water from the river, KMC treats the water at the Indira Gandhi Water Treatment Plant (WTP) of capacity 260 million gallons per day at Palta Water Works.
Water from these waterworks is sent to Tallah pumping station for temporary storage and onward distribution to the City.
Which is the Best Water purifier for KMC Water in Kolkata
See, there are 3 kinds of water purifiers
- RO (RO+UV+UF)
- Non-RO (UV+UF)
- Gravity Based Water purifier
Following Must be the TDS level of water to use different types of filter
| Purifier | TDS Level |
| RO | Above 350 |
| UV + UF | Below 200 |
| Gravity | Below 200 |
A study conducted by Jadavpur University’s School of Water Resources Engineering has even recommended that residents should opt for the piped water that the Kolkata Municipal Corporation (KMC) supplies for drinking purposes if it is sourced directly from the tap as this is more beneficial than mineral water.
The KMC removes the hardness of water and the water is perfectly fit for drinking purposes.
But wait, water has to travel in underground water pipelines until it reaches to your kitchen tap.
This water is contaminated with dust, human waste, and bacteria and viruses developed at the walls of the pipelines.
It is recommended to purify this water before you drink and use it in kitchen.
What Govt recommend is just a Non-RO water purifier for this purpose.
You can use either one out of two
- UV+UF Water purifiers
- Gravity Based Water purifier
Difference between UV+UF and Gravity based water purifier
| UV+UF | Gravity Based |
| Equipped with UV (Ultraviolet) technology | not equipped with UV technology |
| Required electricity for UV bulb | It operates without electricity |
Main difference between the UV+UF and Gravity based water purifier is the UV technology.
The gravity-based water purifier is a non-electric one and does not come with UV (Ultraviolet light) technology.
UV is an ultraviolet bulb that is fitted into the water tank of purifiers. It prevents the reproduction of pathogens in the stagnant water of the water tank.
My Suggestion:- I suggest you must go with UV+UF Non-RO water purifier as it provides additional protection in the form of UV technology.
