A Packaged Drinking Water Unit is a small to medium scale enterprise that manufactures purified drinking water using modern filtration, purification, and bottling technologies. The production process involves procurement of water, filtration through sand and activated carbon filters, purification using reverse osmosis, ultraviolet treatment, ozonation if required, quality testing for microbial and chemical safety, bottling or pouching, labeling, and packaging. Packaged drinking water is valued for its safety, convenience, portability, and purity, making it essential in households, offices, hotels, restaurants, hospitals, and retail stores. The unit requires moderate investment in machinery such as water treatment units, RO systems, UV sterilizers, ozonation units, filling and sealing machines, labeling machines, and packaging equipment, along with skilled and semi skilled labor. With growing awareness of safe drinking water and hygiene, the market for packaged water is strong and continuously expanding. By producing high quality, safe, and hygienically packed drinking water, the unit can achieve steady demand, repeat orders, and good profitability, while also exploring opportunities in branded retail packs, bulk supply, and institutional contracts.
