Initially, occupiers of Zuccotti Park were relying on fast-food restaurants and other establishments in the area for their restrooms, the Los Angeles Times reported.
But neighbors of the park complained to public officials that protesters were urinating and defecating in public spaces.
Occupy Wall Street's Web site said Friday the group "is providing access to porta-potties in a private, well-lit space with 24-hour security, only 2 blocks away from the square," adding, "We will continue to work hard to improve the quality of life at and around Zuccotti Park, as we continue pursuing our larger purpose of improving the quality of life for all."
Singer Bette Midler offered to pay for toilets for the group last week, but a permit requesting to put them in the park was denied. The portable toilets are located on a loading dock of the United Teachers Federation building.
In a joint statement, several local politicians praised the protesters, saying, "We appreciate their attention to this issue."
The statement went on to say, "The fact that both the City and OWS are making progress in addressing serious quality-of-life issues signals that there is a path for solving these and other emerging concerns."
