This bill would require water bottle-filling stations in city buildings operated by the Department of Citywide Administrative Services (DCAS) to be made available for use by members of the public. The DCAS commissioner would prescribe by rule the limitations on such public access to water bottle-filling stations for purposes of safeguarding public safety or health. The bill also would require the locations of city buildings with water bottle-filling stations available for public use to be posted on the 311 website and mobile device platforms.
