Douglas Demonstrates Cost of Water

Alan Hutson

For the 2015 Houston WaterWeek, the Southeast Chapter of Texas American Water Works Association (TAWWA) sponsored a demonstration tent at the City of Houston’s Northeast Water Purification Plant. Treatment, Transmission and Utilities Engineer Lizanne Douglas is an active member of the chapter and volunteered in the tent.

The plant, near the shores of Lake Houston, is home to the City’s WaterWorks Education Center. The one-of-a-kind water destination is designed to inspire citizens of all ages to conserve drinking water resources and protect our environment. 

The Southeast Chapter TAWWA tent demonstration was called “The Cost of Water Game.” It included a 5 gallon bucket (filled with water at the plant), a gallon jug of milk, a gallon of bottled water, a gallon plastic gas can and four Mason jars filled with different quantities of pennies: $8, $4.50, $3 and 3 pennies. 

The four items were set in a row on the table with the jars placed in front of them — out of order. Student volunteers attempted to match the jars to the items according to cost. Answers stimulated teaching moments to explain the relatively cheap cost of tap water compared to other items, especially bottled water.
