The Town Hall School has Reverse Osmosis plant to provide drinking water to the college. Hot Water is also made available round the clock. Town Hall School has reverse osmosis plant to purify water. Reverse Osmosis is a process in which dissolved inorganic solids (such as salts) are removed from water. This is accomplished by household water pressure pushing the water through a semi permeable membrane. The membrane allows only the water to pass through, not the impurities or contaminates. These impurities and contaminates are flushed down the drain. It produces high-quality dematerialized water. It uses most modern membrane technology.
