Water in Chennai comes from many sources — Metro supply, borewells, private tankers and, in some areas, desalinated water — and each brings its own problems. Coastal borewells turn salty, inland borewells carry iron and hardness, tanker water can be muddy or contaminated, and stored water can grow bacteria. Intellect Aqua designs and installs water treatment plants in Chennai that target the exact problems in your water, for apartments, hotels, hospitals, schools, offices and industries.
Common Water Problems in Chennai
- Salinity and high TDS: Common in borewells near the coast and in low-lying areas. Water tastes salty and damages fittings.
- Iron: Yellow or brown water, rust stains on tiles and clothes, metallic smell — typical in many suburban borewells.
- Hardness: White scale on taps, geysers and tiles; stiff laundry.
- Turbidity: Muddy tanker water, especially after rains.
- Odour and colour: Organic matter and hydrogen sulphide in some borewells.
- Bacteria: Contamination in sumps, overhead tanks and old pipelines.
Because sources mix — Metro water one week, tanker the next — a good treatment plant must handle changing quality, not just one test result.
Water Treatment Systems We Build
Pressure Sand and Multigrade Filters
Remove mud, suspended solids and turbidity. The first line of defence for tanker and borewell water.
Activated Carbon Filters
Remove chlorine, odour, colour and organics, and protect softeners and membranes.
Iron Removal Filters
Oxidation and special media remove dissolved iron and manganese, ending rust stains. See our iron removal plants.
Water Softeners
Ion-exchange softeners remove hardness and stop scale. See water softener plants in Chennai.
Ultrafiltration
Removes fine particles, bacteria and cysts while keeping minerals. See UF plants in Chennai.
Reverse Osmosis
Reduces TDS and salinity for drinking and process water. See RO plants and industrial RO.
Disinfection
UV, ozone or chlorination for microbiologically safe water.
Choosing the Right Combination
| Problem | Typical solution |
|---|---|
| Muddy tanker water | Multigrade filter + ACF |
| Rust stains, iron smell | Iron removal filter + ACF |
| White scale, hard water | Filter + ACF + softener |
| Salty borewell water | Filter + ACF + antiscalant + RO |
| Bacteria in stored water | UF or RO + UV, tank cleaning |
| Boiler and process water | Softener / RO + DM |
We do not sell RO where a softener will do, or a softener where the problem is salinity. The water test decides.
Designing for Changing Water Sources
Because many Chennai buildings switch between Metro, borewell and tanker water, we design for the worst likely source, not the best. That may mean extra filtration capacity, an iron removal stage that can be bypassed when not needed, or an RO sized for the highest TDS you might receive. We also design sump and overhead tank layouts to avoid stagnant water.
Whole-Building and Point-of-Use Solutions
For apartments and hotels, a central plant treating all water entering overhead tanks protects every flat or room. For drinking water, a dedicated RO plant feeding kitchens or dispensers is more economical than treating all water to drinking standard. We help you choose the right mix.
Keeping Sumps and Tanks Clean
Even the best treatment plant cannot help if water is stored in dirty sumps and overhead tanks. Sediment, algae and bacteria build up over time, especially after monsoon flooding or when tanker water is stored. We recommend periodic tank cleaning and disinfection, and design treatment so water is filtered before it enters the overhead tanks. For apartments, we can include tank cleaning in the AMC schedule.
After the Monsoon
Heavy rains can push contaminated water into sumps and change borewell quality for weeks. After floods, we recommend testing water, cleaning sumps and tanks, backwashing filters thoroughly and checking softener resin and RO membranes for fouling. Our AMC clients receive a post-monsoon inspection so water quality is restored quickly.
Industrial Water Treatment
For factories in Ambattur, Guindy, Sriperumbudur, Oragadam and beyond, we design complete systems for boilers, cooling towers and process lines — softeners, RO, DM plants, UF and dosing.
Service and AMC
Filters need backwashing, media needs replacing, softeners need salt and resin care, and RO membranes need cleaning. Our AMC in Chennai covers it all, including plants installed by others.
