The Virgin River cuts through a towering red rock gorge flanked by forested plateaus as it meanders through Washington County in southern Utah. The river is the primary source of water for the fastest-growing metropolitan area in the United States, which includes the city of St. George. Washington County is the largest employment center in southwest Utah, with a population of 200,000 that is expected to double by 2060. 

It’s also the hottest and driest county in Utah, and it’s dependent on a singular water source: the Virgin River Basin. But the Virgin’s waters are thinning from climate-change induced drought and overuse. Water conservation is necessary to meet the increasing demands of growth, and Washington County boasts some of the toughest measures in Utah — including a bold program to “buy” residents’ grass as a way to get them to swap in less water-dependent plants.

Grass is thirsty. Statewide, 70 percent of residential culinary water is used on lawns. By shifting landscaping away from grass and to plants more readily adapted to the climate, the Washington County Water Conservancy District estimates that residents can reduce landscape watering to 11 gallons per square foot annually, compared to 56 gallons for conventional turf.

The Washington County Water Conservancy District began its turf buyback program in December 2022. “Utah is now on the front lines of water conservation,” says Doug Bennett, conservation manager for the district and a leader in developing turf buyback programs across the West. “The turf buyback program is at the forefront of the county’s conservation strategy. Conservation doesn’t require expansion of infrastructure, making it the most cost effective water supply strategy.”

Bennett credits the success of Washington County’s program to a streamlined, incentive-based system. He explains, “I like to say it’s as simple as check in, dig in, cash in.” Residents first register for the incentive program. Next, the conservancy district sends someone to document the square feet of turf to be replaced on the property. Residents then have one year to complete their projects. When the yard is ready, there is one more county inspection. The resident receives a check a few weeks later.

The payout is $2 per square foot of converted turf, up to 5,000 square feet. After that, the rate is $1 per square foot. That money is cost-shared between the Washington County Water Conservancy and the state of Utah, which matches the county dollar for dollar. The Utah Legislature allocated $8 million dollars to launch the program, with $3 million recurring annually. To maintain and grow the program, proponents are requesting an additional $12 million from the state legislature. 

Participants can select from an extensive list of native plants that are adapted to need less water, including fragrant sagebrush, yucca, succulents and wildflowers like the firecracker penstemon. There are some specific parameters to qualify for the program, such as installing drip irrigation. Mulch must be placed on the soil’s surface to reduce evaporation. At maturity, plants must cover 50 percent of the project area. Non-permeable barriers like concrete and plastic are not permitted because they prevent rainfall and air from passing through the soil. Bennett notes, “We want the plants to thrive!” Artificial turf is allowed, so long as it has perforations for water and air. The program also requires a conservation easement for the property, to ensure that current or future residents will never return grass to the project area.

To date, 2,044 applications have been submitted and 918 projects completed in Washington County. “We’re projecting that by the end of 2024, our program participants will have transformed enough nonfunctional lawn to be equivalent to a roll of sod about 280 miles long,” Bennett says. “Collectively, these projects should reach 100 million gallons in annual savings by year’s end.” That is enough water to supply 520 single family households.

Bennett recognizes that increased education will boost public participation. He recalls the slow start when Las Vegas launched a similar program: “In 2000, nobody cared. Then in 2002, the drought was so severe that the Colorado River produced just 25 percent of its typical runoff.” (That same drought across the Southwest has persisted for two decades and is known to be the worst in 1,200 years.) Twenty-two years later, Las Vegas’s daily per capita water use has been cut in half. “It was unprecedented for a community [to] save that much without actually just shutting off the water,” Bennett says.

Since 2000, Washington County has reduced per capita water use by 30 percent, the most significant decrease in Utah. Bennett attributes this success to the realities of living in the desert: “Our residents live on the northern edge of the Mojave Desert, and it’s pretty conspicuous by the native terrain,” he explains. In other words, they have “relatively high awareness of the scarcity of water” they face because the landscape itself provides constant reminders.

That’s not the case elsewhere in Utah. “The other major population centers are in the northern part of the state, characterized by mountain ranges, cold and snowy winters and a perception of water abundance,” Bennett says. “Most recently, drought conditions that affected the Great Salt Lake have escalated awareness of hydrologic conditions in northern Utah.”

Despite Washington County’s per capita water savings, because of its rapid growth and development, its overall water use has still increased by 15 percent since the turn of the century. In short, existing water conservation measures do not fully offset the pressure that growth is putting on the water system. This has pushed the county to set the strictest ordinances for new construction and landscaping in Utah. The county now limits lawns to eight percent of property size on all new residential developments. There is a total ban on “nonfunctional grass” at new commercial, institutional and industrial developments. This even prevents new golf course developments. (The caveat is that golf course developers must come up with their own non-potable water source and secondary recycled water sources for irrigation.) The county also reuses water to irrigate public spaces like parks, schools, golf courses and county facilities. 

Through turf buyback and other conservation measures, Washington County aims to reduce per capita water use by another 14 percent by 2030. The county also has a 20-year plan to diversify and conserve water sources, which includes tiered water rates, water recycling and education.

As part of this effort, the new Chief Toquer Reservoir is under construction 20 miles northeast of St. George. The $75 million project, slated for completion in 2025, includes a 19-mile underground pipeline intended to retain up to 3,500 acre-feet of water that is currently lost to seepage at nearby Ash Creek Reservoir.

Meanwhile, a controversial proposal for a 143-mile Lake Powell pipeline, which would import 86,000 acre-feet of water to Washington County, has not progressed amid ongoing efforts to maintain adequate water levels in the reservoir. This was previously considered the savior of Washington County’s water woes, but the hamstrung project has pushed the region to look toward conservation instead. Despite last winter’s above average precipitation, the Colorado River’s Lake Mead and Lake Powell — the largest reservoirs in the country — are only at 36 and 31 percent of capacity respectively. 

The Colorado River supplies water to 40 million people across its basin. The Virgin, a tributary of the Colorado, cascades from a cave tucked high in the pink cliffs of the Markagunt Plateau, before flowing through Zion National Park on its way to a 500-million-year-old gorge. On its descent, it enters seven reservoirs that distribute water across Washington County. One hundred and sixty miles from its source, the remaining water arrives at Lake Mead in the northern Mojave Desert. 

High demand and aridification have reduced the Colorado River system’s flows — including the Virgin’s. Utah is one of seven states (along with Arizona, California, Nevada, New Mexico, Colorado and Wyoming) that must cut down on Colorado River consumption and create a new drought management plan by 2026. While the states don’t yet align on the best approach, there is one water conservation effort they all agree upon: to reduce non-functional turf by 30 percent.

In 2023, the Utah Legislature approved a water-efficient landscaping program as part of the state’s goal to reduce per-capita water use by 25 percent by 2025. Utah is implementing landscaping parameters that restrict lawns to no more than 50 percent of a landscaped area in new residential developments (still much higher than Washington County’s eight percent.) Three other water conservancy districts in Utah have implemented landscaping ordinances, but they are not as expansive as what is included in Washington County’s program. “The state funding may not be used on parks or golf courses, but Washington County’s program includes them,” Bennett notes. “We also rebate conversion of manmade water features such as swimming pools, ponds and ornamental streams.” The county also created its own customer engagement process, which Bennett points to as one reason that participation has been higher here than in the other districts: “It makes it a bit easier for customers to communicate with our program and understand the status of their project.” 

While removing turf can make a big difference in residential water use, that alone cannot shoulder the burden of reducing water consumption. The majority of Washington County water is used for irrigation; statewide, a whopping 68 percent of diverted water is used to grow alfalfa for the beef and dairy industry. This is even higher than other Colorado River states, which utilize an average of 46 percent of water diverted from the river to grow alfalfa and other cattle feed crops. A recent study shows that reducing demand for these products can create some of the biggest water savings from citizens. 

And while turf buyback programs and other water conservation measures are designed to ensure an adequate water supply for a growing population, it’s also important to consider a more fundamental need: to keep water flowing in the Virgin River. The river shapes the iconic landscape of Zion National Park, which draws five million visitors per year, and supports wildlife habitat within the park and beyond. Six native fish call the Virgin River home, two of which are endangered.

“There are tremendous water demands on [this] small river,” explains Elaine York, West Desert regional director for The Nature Conservancy in Utah. York says a significant portion of the river between Zion and St. George is conserved, meaning owned and managed by organizations or government agencies to maintain a relatively natural state and function as part of a healthy river system. This includes two parcels purchased by The Nature Conservancy, which is working with the Virgin River Program — a collaborative effort between local, state, and federal partners — on efforts to balance human water use with conserving the Virgin River ecosystem and protecting native (and some endangered) species. Among these projects, The Nature Conservancy is working with Hurricane, a small city near Zion National Park, to fund and redesign a more efficient water delivery system that reduces water loss during transport.

While grass buyback programs alone won’t save the Virgin or the Colorado River, they are an effective way citizens can cut their daily water use — and a clear demonstration of how successful and lasting changes in water use can begin with government-led incentives that incite broader cultural shifts. For now, Bennett is encouraged by Washington County’s buy-in to rip out turf. “Southern Utah residents have been very receptive to water conservation measures,” he says. “The projects we’re seeing are proof that we can sustain an even higher quality of life while leaving a smaller footprint on our watersheds.”

Iowa is getting federal help to eliminate lead water pipes in the state.

The Iowa Department of Natural Resources is working with local water agencies, planning where to prioritize funds.

As part of the Bipartisan Infrastructure Law, cities and towns in Iowa are reducing the number of dangerous lead water lines.

The Iowa Environmental Council's Director of Climate Initiatives Cody Smith said even homes built as recently as 1988 are connected to the local water utility with lead lines - which leaves people at risk, even in Iowa's big cities like Des Moines and Council Bluffs.

"Particularly with the most vulnerable groups, such as unborn babies or young children, they have extreme and outsize risk related to exposure to lead through lead service lines," said Smith. "That can cause higher levels of lead in the blood and lead to developmental issues for children."

The State's Revolving Fund, which is the primary source for water infrastructure updates, has received more than $620 million as part of the Bipartisan Infrastructure Law.

The IEC says more than 700 communities have benefited so far.

Beyond replacing lead pipes and updating water system infrastructure, Smith said Iowa could also benefit from help with what are known as non-point source projects.

"Which is runoff from agricultural fields and from livestock operations that lead to nutrient pollution in source water," said Smith. "And source water is water that's used for drinking water somewhere in the state."

Smith said those strategies can help farmers and local utilities reduce nitrates and other pollutants in the soil.

The Biden administration has a goal of replacing all lead water service lines in the U.S. by 2031.

Nearly a year after the U.S. Supreme Court left key watersheds unprotected by the Clean Water Act, the Polis administration has designated new protections for some 385 miles across 15 rivers and streams in the Upper and Lower Colorado, Eagle, Yampa and Roaring Fork river basins.

Chad Rudow, water quality program manager with the Roaring Fork Conservancy, said the Outstanding Waters designation is an important tool for protecting drinking water.

"Which means it's protecting the actual quality of the water, and that's the highest level of protection that can be given to a stream within the state of Colorado," he said.

The designation aims to protect existing high-quality waterways from any future degradation, including pollution from development, mining, oil and gas extraction, and other uses. It does not affect any existing uses in the watershed, so long as they don't degrade current water quality.

The designation, which won unanimous approval by the Colorado Water Quality Control Commission in late August, comes after years of work done by conservation groups.

Carrie Sandstedt, senior officer with The Pew Charitable Trusts, said protections are still needed for many streams in the state, and added that protecting water quality is critical not only for drinking water but also healthy wildlife habitat and ecosystems.

"This designation not only protects rivers and streams, it also protects their associated wetlands. It helps preserve important plant life and other species critical for healthy freshwater habitats," she said.

The designation also protects one of the state's biggest economic drivers. A recent study found that Colorado's river basins generated nearly $11 billion in outdoor recreation spending in 2019. Rudow noted clean water is essential for swimming, rafting and other activities across the Roaring Fork Valley.

"We have the second longest contiguous reach of Gold Medal water in our watersheds, so that's high-quality fishing streams. People come from all over the world, literally, to go fly fishing," he explained.

World Water Week is underway, as leaders forge discussions on the global water crisis. Supply issues aren't as urgent in North Dakota, but that doesn't mean conservation is an afterthought.

Dani Quissell - executive director of the North Dakota Water Education Foundation - said the state is lucky to sit on a more predictable water supply, namely the Missouri River, when compared to elsewhere in the U.S.

But she acknowledged that droughts in recent years serve as a reminder for state & local governments, and residents, to not take this precious resource for granted.

At home, she said basic conservation tips still apply.

"Being mindful on when we're letting the tap run where you're filling a pitcher," said Quissell, "and then you walk away for a minute to go let the dog out or something, keeping in mind that that water is running over and right down the drain."

She said that mindfulness should also come into play with other daily practices, like brushing your teeth.

As for policymakers, Quissell encouraged strong communication across various agencies - to ensure water supplies are prioritized when mapping out commercial and residential development.

Surging demand and uneven regulations have plagued western states as key water sources dry up.

Quissell argued that North Dakota closely monitors water use around the state. As climate change threats take shape, she said that has to be the approach moving forward.

"It's a mindset to have in wet periods and dry periods," said Quissell. "I think you build those habits over the long term. I think it's important to be thinking about being a good steward of the resource to have available for our children and our grandchildren."

Agriculture is one sector that has come under scrutiny for how it uses up water for food production. But Quissell said innovation and technology have helped to address that problem.

For homeowners irrigating their lawns, she urged them to run sprinklers at dusk or pre-dawn. That way, the water won't quickly evaporate in the midday heat.
