Incorporated Village of Sea Cliff, 600,000 Gallon Elevated Water Storage Tank
Posted on July 15, 2015
Client: Incorporated Village of Sea Cliff
Location: Aqua, New York
Project Type: 600,000 Gallon Elevated Water Storage Tank
Project Period: 2007-2009
Project Cost: $1,700,000
D&B provided engineering services for the design and construction of a new 600,000 Gallon Elevated Water Storage Tank to replace a 116 year old standpipe located in the Village of Sea Cliff. Rather than making costly repairs and painting the aging standpipe, Aqua New York decided to replace the tank with a larger, more modern elevated water storage tank to meet current Department of Health requirements. The old standpipe tank style does not provide an adequate water supply to meet peak demands or fire protection supply requirements. Further, only 126,000 gallons of the stored water in the standpipe is usable to provide the required distribution system pressures. This can result in poor water quality in the unusable portion of the tank.
The new elevated water storage tank is designed to provide a total of 600,000 gallons of water stored water at an elevation adequate to provide the necessary pressures in highest parts of the distribution system. Since the system has another 500,000 gallon elevated water storage tank, the new tank has been designed with an overflow elevation to match. The system will have a total storage capacity of 1.1 million gallons.
Since the site is located in the center of the Village of Sea Cliff, the Architectural Review Board (ARB) was concerned with the appearance of the tank within the context of the historical Village surroundings. D&B worked with the ARB and the residents of the Village to select the most aesthetically pleasing elevated tank style while still providing the necessary storage capacity and height. Various tank styles were evaluated and presented to the ARB. Visual renderings were prepared and a multi-column style with a conical roof was selected as fitting into the community the best.
The existing standpipe remained in operation during the construction of the new tank. This added to the construction challenges due to the relatively small size of the site. D&B and Aqua NY worked with the Village of Sea Cliff’s Landmark Commission to perform an historical survey and to photographically document both the demolition of the existing tank and the construction of the new tank.
The total construction cost for this facility is approximately $1,700,000. The work is scheduled for completion in 2009.
