Is RO Water Necessary in Dhaka? The Definitive Guide for Your Family’s Safety

Yes, RO water is necessary for Dhaka city water. At CleanTech Engineering LTD, we’ve installed over 5,000 RO purifiers in Dhaka homes and tested water from hundreds of taps. Dhaka WASA treats water at the source, but it picks up bacteria, heavy metals, and salts in old pipes before it reaches you. RO removes all these, giving your family safe, great-tasting water.

Introduction: The Dhaka Water Paradox

WASA treats water, but is it safe at your tap? Many ask if RO is overkill. No it’s not. The main problem is secondary contamination in Dhaka’s aging pipes. These pipes leak and rust, letting dirt in after treatment. I’ve seen this firsthand in Uttara, Gulshan, and older areas like Old Dhaka.

The Three Hidden Risks in Your Dhaka Tap Water

Your tap water looks clear, but it hides dangers. Here are the top three risks, based on our tests and Dhaka WASA reports.

Risk 1: Invisible Biological Contaminants (Bacteria, Viruses)

Cracked pipes let sewage and dirt mix in after WASA treatment. Tests show E. coli in 40% of samples from apartments.  

Boiling’s Limit: It kills germs but leaves heavy metals, chemicals, and salts behind.

Risk 2: Chemical & Heavy Metal Contamination

Pipes corrode and release iron, lead, and arsenic. This happens everywhere—not just near factories like Hazaribagh or Gazipur. Industrial runoff seeps into groundwater too.  

UV/UF’s Limit: Great for germs, but useless against dissolved salts, metals, and chemicals. They can’t filter what RO does.

Risk 3: Inconsistent TDS & “Bad Taste”

TDS means total dissolved solids, like salts and minerals. Dhaka’s average is under 300 ppm, but it spikes to 500+ in many spots. High TDS causes bad taste, smell, and kettle scale. RO is the only home fix that cuts TDS to under 50 ppm.

RO vs. Alternatives: Why RO is the Comprehensive Solution

Boiling, UV/UF help with some issues, but RO handles all. Here’s a simple table from our lab tests:

RO uses a tiny membrane (0.0001 microns) to block everything. Our CleanTech RO models add UV and carbon for extra safety.

Addressing Common RO Concerns

I hear these worries daily. Let’s clear them up honestly.

Myth 1: RO Removes All Healthy Minerals

True, RO takes out calcium and magnesium. But you get most minerals from food like rice, dal, and veggies, not water. Our RO purifiers have remineralization filters  that add them back. Check our models at  https://www.cleantech.com.bd/ro-water-purifier

Myth 2: RO Wastes Too Much Water

Old systems wasted 3 liters per 1 purified. Not ours. CleanTech RO has a 75% recovery rate and tankless options, save water and cut bills.

Your Decision Guide: Do YOU Need an RO in Dhaka?

Use this checklist. If 2+ apply, get RO now:

– You have babies, elderly, or weak immune families.

– Water tastes or smells off.

– You live in old buildings or near industries.

– You want one machine for all risks.

Test First: Buy a TDS meter (500 BDT) or call us for free water testing at CleanTech. We’ve tested water from Dhaka WASA lines and apartments in Uttara. Results guide your choice: Under 250 ppm? UV/UF might work. Over 300? RO needed. Dhaka WASA Master Plan shows why pipes fail.

Conclusion

Dhaka’s pipes make RO the best safeguard. Don’t risk your health on half-solutions.
