Leiden University is committed to reducing our water consumption.

We use water for many things: not only for drinking but also for lab research and flushing the toilet, for example. By looking critically at our water needs, we can limit the environmental impact of our water consumption. Water-saving toilets and taps are standard therefore and are being installed everywhere, especially in renovations and new builds. Lower water consumption means less wastewater and treatment, which in turn means a smaller carbon footprint.

Tap water stations

Together with Join the Pipe Foundation, the University has had more than 30 tap water stations installed in its buildings. Students, staff and visitors can fill their reusable water bottles here. This saves a lot of disposable water bottles and CO2 emissions related to the production and transport of bottled water. For the locations of the tap water stations on Leiden en The Hague campuses.

What you can do

One easy way to save plastic is to bring a water bottle. Report leaking taps and toilets to the Servicedesk in that building to stop water from being wasted. If you think lab equipment is using too much water, let us know and we’ll install a water meter to see if this really is the case and if measures need to be taken.
