If you do not take any measures to purify it, the water carries a risk of contamination. This happens because of old building plumbing or unclean storage tanks. In 2019, a study by the Bureau of Indian Standards took samples from 21 cities, and only Mumbai\u2019s sample passed every check. TDS value for tap water ranges between 80 and 320 mg\/L. On the other hand, the TDS for groundwater averages around 719 mg\/L.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">You should know how safe your water is in Mumbai because it may be safe to drink at the reservoir but not from the kitchen tap.

On the other hand, Panjrapur Water Treatment Plant treats water from Bhatsa, Vihar, and Tulsi. The plant supplies the eastern suburbs from Mulund to Sion, and Sion to Mazgaon.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The plants use the traditional treatment method. A coagulant is added so that mud and fine particles clump together. The clump settles out, and the water then passes through sand filters.

The treated water flows to 27 service reservoirs across the city and from there into the distribution network that reaches your building.\u00a0<\/span><\/p>\n<p><strong>Also Read: <a href=\"https:\/\/www.rentomojo.com\/blog\/tds-level-in-water-purifier\/\">TDS Levels In Water Purifier: What Is The Ideal Range?<\/a><\/strong><\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Does_BMC_Tap_Water_Contain\"><\/span><b>What Does BMC Tap Water Contain?\u00a0<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">BMC tap water contains a small amount of dissolved minerals, chlorine, and very little else when the treated water leaves the plant.

India&#8217;s drinking water standard (IS 10500) requires at least 0.2 mg\/L of residual free chlorine. The small amount kills germs as the water travels through kilometres of pipes.

If you leave white crust on the kettle or faucet, it is because of the excess levels of minerals. So, your water might have moderate TDS, but it may still feel soft because the dissolved solids are not calcium or magnesium. Lakewater is usually soft.

BMC water is low in TDS, but it can pick up germs in the pipes. An RO water purifier on 60 ppm water wastes water and leaves you with water that has almost no minerals.\u00a0<\/span><\/p>\n<table>\n<tbody>\n<tr>\n<td><b>Your water source<\/b><\/td>\n<td><b>Typical TDS<\/b><\/td>\n<td><b>Purifier you need<\/b><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">BMC supply only<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Low (under 200 ppm)<\/span><\/td>\n<td><span style=\"font-weight: 400;\">UV + UF + activated carbon<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">BMC + occasional tanker water<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Varies<\/span><\/td>\n<td><span style=\"font-weight: 400;\">RO + UV with a TDS controller or mineral cartridge<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Borewell or mostly tanker water<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Often 500+ ppm<\/span><\/td>\n<td><span style=\"font-weight: 400;\">RO + UV (the right water purifier for borewell water)<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Old building, frequently cloudy or brown water<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Any<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Any of the above, plus a sediment pre-filter<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><span style=\"font-weight: 400;\">A handheld TDS meter can tell you the range of TDS in your water.

Also, you might need an RO in this case.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">No matter what purifier you choose, it depends on whether you maintain it well. Check for clogged UF membranes or dead UV lamps. Rentomojo\u2019s own purifiers, including DriftGo, DriftLux, Nirapure, and DriftPro, are available with free filter changes every six months. When you know you will shift to another building and are not yet sure of the building\u2019s water quality, renting a water purifier is practical.
