The fountain (185 x 60 feet) is covered by a thin scrim of water with programmable three-foot-high spouts that create a dancing water feature throughout. Sections of the fountain can be turned partially or completely off to allow for concerts or events. Rainwater is captured on site and stored in a cistern below the park to feed the fountain and to support the park's landscaping irrigation system.

Water Safety Management

The Center City District follows industry-recommended, best practices for proactive water-safety management of the fountains in John F. Collins Park, 1707 Chestnut Street; Sister Cities Park, 18th Street and Benjamin Franklin Parkway; and Dilworth Park at City Hall.

Using an authorized testing kit recommended by water treatment experts Klenzoid, Inc. of Conshohocken, CCD staff test the water in all fountains and water features twice a day in each park to insure there are no health or safety problems. In addition, Klenzoid, Inc. visits each park once a week and independently takes samples of the water and sends them to a certified laboratory. The operating systems for each fountain mechanically control the level of chlorination and can be easily and immediately modified if any deficiencies are found in water quality.

Please note that since the fountain water is chlorinated it may not be safe for pets.

Rothman Institute Ice Rink

In October, the fountain at Dilworth Park is turned off for the season to begin installation of the Rothman Institute Ice Rink. The fountain and subsurface reservoir and pumps are drained to prevent freezing and will remain dormant until spring.


Pulse, a specially commissioned work of public art created by internationally recognized artist Janet Echelman will be integrated into the programmable fountain at Dilworth Park and will trace the path of trains traveling on the three lines below the park in real time, coded to the colors associated with each transit line. Thin columns of dry mist will emanate from the fountain, evoking the steam that rose from the city's first water- pumping station that was located on this site as well as the steam from the trains at the Pennsylvania Railroad Station that was located across the street. Echelman's use of dry mist enables people to walk through the installation without getting wet. A description of the installation, including a simulation of this work of art, entitled Pulse, can be found by clicking here.
