Water Play Areas & Interactive Fountains

Keeping Water Play Areas / Interactive Fountains Clean


A water play area filled with parents and children.

A more recent addition to the recreational water attraction scene is the water play area (may also be called an interactive fountain, wet deck, splash pad, spray pad, or spray park). People may not realize that although there is no standing water in these attractions, the spray water will rinse any contaminants (for example, diarrhea, vomit, and dirt) down into the water holding area and be sprayed again. In other words, the water is recycled through the system. As a result, it is possible for the water to become contaminated and cause outbreaks of illness.

Title: Make a Healthy Splash! Sub-title: Swallowing water in interactive fountains, splash pads, and spray parks might make you sick.(Cartoon image of a germ) Germs can get into the water through poop coming out or washing off our bodies.(Icons of head swallowing water with germs and head with thermometer getting sick) Swallowing water containing germs can make you sick with diarrhea.(Icon images of children playing in an interactive fountain with the tank of recycled water below and images of germs in the water). Water in interactive fountains is typically recycled and might contain germs. Water treatments like chlorine don’t kill germs instantly. Pee in water weakens the germ-killing power of chlorine.(Banner across water tank image) Keep pee and poop OUT of the water. DO:

Because water play areas / interactive fountains are relatively new, health departments may not have specific requirements for how this water is treated. It pays to be proactive by building water play areas or interactive fountains like any other water attraction is built. They should include adequate disinfection and filtration systems even if this is not currently required by the local or state pool code. The addition of secondary disinfection, like ultraviolet light or ozone, should be considered and is now required in New York State. Health departments should also ensure that pool codes are updated to include water features that do not have standing water.


Outbreaks Associated with Water Play Areas / Interactive Fountains

During the summer of 2005, an outbreak of cryptosporidiosis occurred at Seneca Lake State Park in New York. Over 1,700 people may have been infected with 425 laboratory-confirmed cases of cryptosporidiosis and 1,374 probable cases were identified (1). Cryptosporidium was traced to the water tanks that supplied the 11,000 square foot wet deck (spraypark). In response, New York passed emergency public health regulations to govern the design and sanitation of such attractions statewide.

A 1999 outbreak of diarrheal illness affected 44% of patrons (an estimated 4,800 people) who visited a new interactive fountain in a beachside park (2). When officials from the health department inspected the interactive fountain, they found that the water drained from the play area into an underground reservoir for recirculation. The problem turned out to be a result of inadequate chlorination and the lack of a filtration system. The chlorine tablet erosion feeder had not been filled for weeks and the designers did not include a filtration system.
