Rooftop Water Tanks Proper Maintenance is Essential

New Yorkers love to brag about having the best-tasting drinking water in the country, although

residents of high-rise buildings may not realize that their water makes an extra stop on its way from the reservoir. When high-rise residents turn on their taps to have a drink of water, take a shower or wash the dishes, the water comes from a tank located on the roof of the building. In addition to serving as a storage device, the tank creates water pressure through gravity which brings water to each apartment as needed.

Like other building components and systems, water tanks have to be routinely maintained so they can continue to operate safely and efficiently. A decision to put off maintenance today will most certainly be regretted tomorrow, says Anita Sapirman, president of Saparn Realty, Inc., a Manhattan-based residential property management firm. When it comes to water tanks, preventive maintenance is the name of the game. The water tank requires regular attention to prevent the need for emergency interventions which can be enormously expensive.

Richard Silver, president of American Pipe and Tank Lining Company, a Manhattan-based firm that specializes in water tank maintenance, adds, The cleaning of water tanks is not just prudent maintenance, but New York City law. Tanks containing potable waterthat is, water for consumption purposesmust be cleaned and disinfected no less than once a year. According to New York City Department of Buildings spokesperson Ted Birkhahn, the Building Code sets forth specific guidelines for cleaning the tank as well as for maintaining the physical structure including supports and covers.
