Drinking water can be supplied in bulk via drinking water trailers or at water points connected to water tanks. Trailers typically feature two troughs with a number of taps, allowing several people to use the facility at any one time. It is important to consider the volume of water provided by one trailer and relate this to the number of expected attendees and the duration of the event.

It is also important to provide hose pipes with nozzles that have an automatic cut off when people have finished filling larger containers to minimise waste and run off. It is also important to ensure you have a backup supply of potable drinking water, especially when working in rural events.

For other events, such as conferences and meetings, avoid distributing bottles of water or plastic cups by encouraging the use of jugs of water and reusable cups. It is always better to reduce the use of, or reuse, drinking bottles rather than recycling them.
