Color Changing Shower Head Promotes Water Conservation

Written by Megan Treacy

A new shower head technology alerts you when you’ve been bathing for too long and helps you to cut down on the water you use in the shower. A light turns gradually from green to red as time ticks on, and when it reaches red, it’s time to get out.

“It encourages [people] to take shorter and more energy efficient showers,” said one of the co-inventors of the Uji Showerhead, Brett Andler to NPR. “By letting people become aware of how long they’re in the shower, we’ve actually been able to cut shower time by 12 percent.”

Of course there’s no major consequence like the water shutting off once time’s up or anything like that, but just the reminder that a set amount of time has passed helps people to take water conserving action. Currently the prototype hits red at seven minutes so that people will be out of the shower by minute eight, but the inventors are considering having a model with an adjustable time limit once it hits the market.

Priced at $50, Uji’s website says: ”The Uji showerhead will pay for itself in energy and water savings after only 7 months of use. After this the showerhead will save you about $85/year installed. Its great for families with smaller hot water tanks or teens who take too long in the shower.”

The product received grants from the DOE’s Lawrence Berkeley National Laboratory for prototyping and testing, and Uji has already gotten commitments from at least four universities to pilot the shower heads in their dorms to save water. As for the rest of us, Uji plans to have the shower head on the market by early 2014.

Great idea, it needs a control valve/button you can use to shut off the water when shampooing or shaving that will keep the water at the same temperature. Most water companiesin Los angeles give low flow showerheads away for free to help with water conservation.

Try your water agency you might be surprised at the giveaways for water conservation.

Looks great, as long as I have enough time to wash body & hair - and rinse.

It's too pretty. One wants to keep the light going.

is there a choice of color? It might have the opposite effect - I might want to stay in longer just because I like the colored light :) Or, instead of a light, a voice could be stored in the device that says "get out of the damn shower already!"

I've seen this in the PCH advertisements that you sometimes get in your mailbox. @ Gloria p., I suspect it may use an infrared light that you could shine a laser pointer at to stop it's cycle a bit to shave your legs, ha! Just guessing. ;0)
