The Institute for Water Research supports calls for an end to the  use of single-use plastic water bottles except in emergency  situations. The environmental and health consequences of the  manufacture, transportation, use and disposal of these bottles are  well documented. The Institute does not supply single-use plastic  water bottles for meetings, alumni events, conferences, etc. and  requires catering suppliers to comply with this. Both staff and  students are encouraged to make use of multi- use water bottles.
