From the NYC DEP:
Environmental Protection Commissioner Cas Holloway today announced the demolition of two elevated water storage tanks in Queens. The tanks – located at 93-02 199 Street, in Hollis, and 84-02 164 Street, in Jamaica Estates – are no longer part of the water distribution network, and local elected officials and community organizations have requested their removal. Site mobilization for the demolition process started March 1. The 199 Street tank will be demolished next weekend and the tank at 164 Street will be demolished the second week of April. The cost for both demolitions is $545,000.
The two 250,000 gallon capacity tanks were built in 1930 by the Chicago Bridge and Iron Company on behalf of the former Jamaica Water Supply Company. The tanks were originally used to store water and maintain pressure in the distribution system. DEP assumed control of the tanks upon the purchase the Queens portion of the company in 1996. Since then, DEP has replaced and upgraded water mains in Southeast Queens to improve distribution and water quality. For example, a network of 20-inch mains was installed in the last 10 years in the surrounding community and large numbers of outdated fire hydrants were replaced with standard ones to enhance the fire fighting ability of the system. Several other projects are currently under construction, including over three miles of a 48-inch water main in Jamaica and Hollis. Due to investments like these over the years, the tanks have been obsolete for more than a decade.
