APW Water Scene Investigation
Inspire participants to adopt home water conservation practices through the installation of water efficient technology and the comparison of their savings with other water users'.

Water Scene Investigation

The WSI is a fun and easy way for students and adult community members to become Water Scene Investigators and really save water! This activity starts with an eye-opening examination of water use and water-use technology.  It includes installing a simple water-saving technology in the home: a faucet aerator.  WSI Investigators measure their faucets’ average flow rate before instillation of the new aerator and after the installation of the new aerator.  They report their water savings here.  And they see how their actions compare to and combine with others’ to save more water in Arizona.

The WSI program can be used by educators, businesses, public agencies, non-formal education, and the community to engage 5th through 9th grade students in a project focused on water conservation, efficiency, and water auditing. The WSI is a two‐day, in‐classroom project; the two days can be separated by a week to allow for homework completion. And it may be easily adapted for non‐classroom use, whether that is in community groups or clubs, with youth or with adults.

The WSI inspires simple actions that result in real water savings. This year, students involved in APW programs that use the WSI activity in and out of school saved a projected 18,973,169 gallons of water through applying their knowledge and installing water efficient devices.

WSI Investigators will:

  • Brainstorm household water uses
  • Learn about water efficient technology
  • Learn how to install an aerator on a faucet
  • Follow a set procedure
  • Measure water flow and inventory water use
  • Make mathematical conversions
  • Analyze scientific data and draw conclusions
  • Make recommendations for ways to use water more efficiently
