As part of the 2014 March Water Awareness Campaign, the HGSE Green Team assembled a water display that demonstrates just how much water the average shower can add up to.

The water display doubles as an art display and can be showcased in a popular common area or public space like HGSE’s Gutman Lobby.  An accompanying poster offers fun tips and educational facts for all those passing by and curious to learn ways to cut that shower time down to five minutes or less!

Super easy to assemble and very portable, the HGSE Green Team can even take this water display on the road and proudly display it at other water-minded sustainability events. 

Create your own display:

1. Gather your supplies: five-gallon jugs,* zip-ties, self-adhesive velcro!

For a 5 min vs. 10 min vs. 15 min shower display you’ll need 12 (five-gallon) jugs total. The EPA estimates that standard shower heads use 2.5 gallons of water per minute (GPM). Our water display assumes a low-flow shower head at 2 GPM.  (*Pro tip: flat-bottomed water jugs are sturdier for stacking and hold onto the self-adhesive velcro strips better!)

2. Locate and reserve some prime real-estate to showcase the water display.

The HGSE Green Team was able to reserve a table in the lobby of the Gutman Library, adjacent to the Café and Student Affairs Office.

3. Design an eye-catching poster.

Include fun and educational water awareness facts and tips to accompany the display and offer passersby more information about curbing their water use.

4. Stack ‘em up!

Use the zip-ties to cinch the handles together and self-adhesive velcro to keep the stacked jugs stuck! 2 jugs = 5 min shower, 4 jugs = 10 min, 6 jugs = 15 min.

5. Assemble your display.

Here’s a quick video of the HGSE Green Team in action! Step back and appreciate how quickly those precious gallons of water stack up in a shower!

Who to contact, partner with, etc:

Contact your school’s Department (Events, Operations, etc.) to see about reserving space in a public area for the water display. Operations/facilities might also have some good leads on offices with five-gallon water jugs on hand.
