Experts share tips, insight into water-saving strategies

OK, Coloradans, let’s clear the shampoo out of our eyes: Your shower water is likely connected to the Colorado River water supply crisis. But can you really help by conserving water at home?

In recent years, two decades of drought and prolonged overuse have brought the Colorado River Basin’s largest storage reservoirs to the brink of collapse. e crisis is reaching Coloradans’ lives in the form of summer lawn watering restrictions, higher utility bills and even a shortage of Sriracha. Some cities have bought agricultural water rights for more municipal water, and people with junior water rights often have their water supply cut in dry years.

Water experts say Colorado residents can help with the crisis, and they have plenty of tips to help the conservation-minded Coloradan start saving water at home. One drawback: In many cases, there’s no guarantee that in-home savings help re ll the system’s struggling reservoirs.

“It’s like, OK great, our city is now saving 10% of what it was using,” said Gregor MacGregor, a water law expert at the University of Colorado. “ e question is, what is your city going to do with that 10%? Are they going to leave it in the Colorado River Basin? Are they going to leave it in a reservoir for drought conditions? Or are they simply going to divide that savings out to build more and then use that savings on new development?” e average American family uses more than 300 gallons of water per day at home, and about 70% of that use is indoors. In the arid West, states have some of the highest per capita residential water use because of landscape irrigation, according to the Environmental Protection Agency. at means that the impact of inhome water conservation is going to be limited in the grand scheme of water use in the Colorado River Basin, where the amount of water stored in reservoirs like Lake Powell and Lake Mead has declined dramatically.

In Colorado, water users run through 5.43 million acre-feet of water per year. One acre-foot supports two families of four to ve people for one year.

Of that, 90%, or about 4.8 million acre-feet, is used by the agriculture industry. About 380,000 acre-feet is used in cities and towns, and of that, only about 46% goes to indoor water uses like toilets, faucets, laundry machines and showers.

“While the bulk of that water to help prevent Lake Powell from collapsing will come from agriculture, cities need to do their part,” said John Berggren, senior regional water policy analyst for Western Resource Advocates. “Municipalities’ water use matters. It’s small … but it matters.” at leaves them with plenty of opportunities for conservation — and accidental waste.

Home water use falls primarily into two categories: indoor and outdoor.

In Colorado, residents tend to use more water outdoors watering their lawns and gardens. at’s led to the rise of water-wise landscaping e orts, like those currently being showcased at the Denver Botanic Gardens.

Indoors, Colorado residents use about 60 gallons per capita each day.

In 2016, toilets were the main culprits of water use in homes nationwide, using 24% of household water, followed by showers, 20%; faucets, 19%; and washing machines, 17%, according to the EPA.

Americans use more than 1 trillion gallons of water each year just for showering. e average shower is eight minutes, which means it uses more than 16 gallons of water at 2.1 gallons per minute.

Letting your faucet run for ve minutes while washing dishes can waste 10 gallons of water. Each year, household leaks waste nearly 900 billion gallons of water nationwide, which is enough to supply water to 11 million homes. And about 50% of the water used outside is lost because of wind, evaporation and runo from inecient irrigation systems, according to the EPA. e EPA says households can boost their water e ciency by 20% when residents switch to products with WaterSense labels. And a shower that lasts for ve minutes using a low- ow showerhead uses 12 gallons of water, according to a 2014 Colorado State University water use fact sheet. the safety or mental health needs of those involved, according to the complaint.

“We’re now in a world where feet matter in Lake Powell. Drops of water matter because we’re on a knife’s edge. When you’re in that tight of a spot, every single water use matters. No matter how small,” Berggren said. ere are a few simple ways to cut back on water use at home, including some Colorado-speci c programs.

Yes, taking shorter showers can decrease water use and cut back on your water bill. e EPA says that, if all 300 million people in the U.S. reduced their shower time by one minute each time, the country could save 170 billion gallons each year.

Turning o the tap while brushing your teeth can save 8 gallons of water per day, and only running the dishwasher when it’s full can save the average family about 320 gallons of water per year, according to the EPA.

But Berggren says rather than changing habits — which we all know can have a hit-or-miss success rate — he’d start with making purchases, like a more e cient shower xture.

Similar savings are possible with toilets: ose made before 1993 use 3.5 to 8 gallons per ush, while high e ciency toilets made after 1993 use 1.6 gallons per ush or less. at means a family of four can save 14,000 to 25,000 gallons per year by switching to more e cient toilets. ( e date of manufacture of most toilets is on the underside of the tank lid.)

Updating your washing machine can also make a big di erence. Conventional, top-loading washing machines use 35 to 50 gallons per load. Newer front-loading machines use 18 to 20 gallons per load, according to CSU.

For those who have updated their appliances and are careful about water use around the house, there’s a way to take at-home e ciency a step further: grey water reuse.

For example, after “Bianca” asked guards to transfer her to another room because she was receiving threats from another woman at the facility, sta told her the women should ght each other, according to the com-
