My day to day experience as a water expert

  At a hotel in T. Nagar, Chennai, the management team began receiving subtle but frequent complaints from guests: “The water feels salty while brushing,” “There’s a residue left on the glasses,” and “The towels feel rough after washing.” Initially, the housekeeping team blamed the laundry detergent, while the kitchen staff suspected the cooking salt. But as the weeks passed, the problem became impossible to ignore. From the bathrooms to the kitchen, every drop of water seemed to carry that unmistakable salty taste. It wasn’t the detergent. It wasn’t the salt in the food. It was the water itself. The Hidden Problem Behind “Salty” Water When the hotel’s water was tested, the results told the real story: High TDS levels (above 1500 ppm) — meaning excess salts and dissolved minerals in the borewell water. Scaling on fixtures — caused by mineral deposits blocking showerheads and taps. Corroded pipes — reducing water flow and affecting the plumbing lifespan. Flat taste in drinking wat...

“Our guests started leaving complaints in the feedback forms — the water in their rooms tasted salty and flat .” That’s how a resort owner from Mahabalipuram described the issue that was troubling them. “Even though we provided bottled water, guests expected fresh, clean water directly from the taps and dispensers. Some said they avoided making tea or coffee in their rooms because of the taste. A few even mentioned it in online reviews, and that really worried us,” he said. The problem wasn’t the service. It was the water. The resort relied entirely on borewell water, which was supplied to every room, kitchen, and restaurant inside the property. Why Did the Water Taste Salty? We asked: “Have you tested the TDS level of your borewell water?” The resort hadn’t. When tested, the results revealed the cause: over 1,000 ppm TDS, indicating extremely high levels of dissolved salts. Here’s what that means: Water with TDS above 300 ppm often tastes salty, bitter, or metallic. Continuous use in...

  I received a call last week from the manager of a mid-sized hotel located near the ECR in Chennai. He sounded rushed and frustrated.  He said, “We need an RO plant for our hotel drinking water. The one we installed last year isn’t working properly, and the vendor has gone completely unresponsive.” I asked him what exactly was wrong, and he explained that guests had started complaining about the taste of the water, and their current system just wasn’t delivering. “Can you install a new RO plant quickly?” he asked.  I understood the urgency, but instead of rushing into a replacement, I asked, “Has your water been tested recently?” He admitted they hadn’t, but assumed a better RO system would fix the issue.  That’s when I knew this was more than just an installation job; it needed a proper diagnosis first. Now, I could’ve just said yes, taken the payment, and replaced the old unit with a new RO plant. But that’s not how we work at Water Sparks. Before replacing anythi...
