Fontus water offers a range of reverse osmosis [ro] drinking water systems. A basic problem faced today is water scarcity, which is worsening by the day, and stringent legislative measures have been undertaken in major metros like mandtory incorporation of rain water harvesting and water recycling. Deteriorating quality of water is another concern due to the increasing pollution of water supply sources [surface and underground]. With 80% of diseases water borne, it becomes increasingly important to safeguard against contaminated water. Where municipal treated water is not available or is inadequate, residents rely on bore well water or tanker water, which is affected by bacteria, viruses and pesicides. Even treated municipal supplies can get re-infected in storage or contaminated in old distribution lines before it reaches homes. Installing domestic water purifiers is not the only solution. It makes economic sense to provide for central drinking water purification system that supplies purified water to every home. Features of ro drinking water systems: simple and compact; effective and versatile to treat water from any source; easy to operate; minimum maintenance; pre-engineered standard plants; available on boo and bot basis also; and purifies water from 100 litres/hr onwards.
