In case you are wondering what that noise is on the main floor of the Davis Family Library today, it is the installation of a new ADA-compliant water fountain that is designed to fill water bottles too. 
The Library Space Team successfully applied for an Environmental Council grant to cover the cost for one. The fountain will count the number of times a water bottle / glass is filled. Next time you are thinking of buying bottled water, think instead about using a refillable container (and thus avoid landfill waste or the energy and financial costs of recycling). It will also be the only ADA-compliant fountain in the Library, so if someone in a wheelchair needs a water fountain, be sure to direct them to this one, which is just opposite the print copy room on the main level.
