With a flood of people comes a wave of water worries.

The population of Frisco, TX, a Dallas-Fort Worth suburb, is expected to almost double between now and 2040. As a result, it leads Texas’ largest cities for projected water needs over the next 25 years.

A data analysis by LawnStarter shows that among the 22 biggest cities in Texas, Frisco will need 151 percent more water in 2040 than it used in 2013. That projection comes from the Texas Water Development Board, which compiles water-use forecasts for cities throughout the state.

In 2013, users in Frisco soaked up more than 8.7 billion gallons of water. That’s the most recent figure available from the Water Development Board. In 2040, water use in Frisco is expected to reach nearly 22 billion gallons. As a means of comparison, the typical Olympic-size swimming pool contains about 660,000 gallons of water, while the typical American family uses 320 gallons of water each day.

‘Precious Resource’

“Texas’ rapidly growing population and burgeoning economy have created new strains on an already precious resource. Recent drought conditions only underline the importance of planning for our future water needs,” according to a report from the Texas Comptroller’s Office.

In the 2012 State Water Plan, the Water Development Board warned that during drought conditions in Texas, the state “does not and will not have enough water to meet the needs of its people, its businesses, and its agricultural enterprises.”

Jean-Philippe Nicot, a senior research scientist with the University of Texas Bureau of Economic Geology, says demand will exceed supply if the population keeps growing and nothing is done to match the supply with the demand. However, Nicot says residents of large Texas cities shouldn’t be “overly concerned” about future water supplies.

“Ultimately, it is a question of cost and economics. Water is available, but it needs to be treated if it’s of poor quality and transported to where it’s needed,” he says.

‘True Change’

In Dallas-Fort Worth, water providers are gearing up for the ramped-up demand.

Denise Hickey, a spokeswoman for the North Texas Municipal Water District, says that about one-fourth of the ballooning demand for water in the Dallas-Fort Worth area will be met through various conservation measures, such as lawn-watering restrictions and water recycling. The district serves a 2,200-square-mile, nine-county swath of the Dallas-Fort Worth region.

From a personal standpoint, Hickey says wasting water must become “socially unacceptable” — just as smoking and littering in public did — before “true change” will happen in water conservation. “A little peer pressure is going to help,” she says.

Here are the 22 largest cities in Texas, ranked in order of their projected increases in water demand from 2013 to 2040.
