New Master Roadmap Guides Industries To Invest in Low-Cost, Low-Energy Ways To Treat Salt Water & Recycle Wastewater
Agriculture accounts for about 90% of total water consumption in the western United States and around 80% in the rest of the country.
This year, droughts, ferocious wildfires, and extreme heat waves are turning farmlands dusty and ranchlands into grass stubble too short to feed livestock. Without adequate water supplies, farmers and ranchers are suffering, facing unprecedented restrictions on water supplies they have relied on for decades.
But even without historic droughts, growing demand for clean water will create shortages — and soon. Water managers in 40 U.S. states expect some portion of their community to experience shortfalls by 2024. But there is a solution waiting in runoff drains, farmlands, and even the ocean.
As water insecurity grows and populations continue to increase, the country could tap unconventional sources, like salt water and wastewater, for agriculture (including irrigation and animal management), thermoelectric cooling, mining, oil and gas extraction, industrial and manufacturing processes, care for city parks and cemeteries, and even drinking water.
Still, technological, economic, social, and cultural barriers staunch the flow of a circular water economy — where water can be recycled again and again. That is why the National Alliance for Water Innovation (NAWI) just published a master roadmap to help guide future national (and international) technology investments that will not only help keep crops watered and livestock well-fed but also make sure no one goes thirsty when devastating droughts sap our water supplies.
The U.S. Department of Energy formed NAWI in 2019 to accelerate the development of energy-efficient desalination technologies, which extract salts and other impurities from both salt water and wastewater. Their goal is for such devices to produce clean water with the same (or higher) quality as current water treatment methods for 90% of nontraditional resources within the next 10 years. Led by Lawrence Berkeley National Laboratory in Berkeley, California, the NAWI collaboration includes the National Renewable Energy Laboratory (NREL), Oak Ridge National Laboratory, the National Energy Technology Laboratory, and more than 250 industry and academic partners.
Waste not. Growing demand for clean water will create shortages—and soon. Now, the National Alliance for Water Innovation’s new Master Technology Roadmap can guide industries to invest in the most promising technologies, so we can recycle salt water, wastewater, and other waste products again and again.

The master roadmap synthesizes the results of the 2020 NAWI Roadmapping initiative, which focused on technical challenges across five sectors: power, resource extraction (mining and oil and gas exploration and production), industrial, municipal, and agriculture. Though NAWI previously published individual roadmaps tailored to each industry, the master roadmap compiles research opportunities that span more than one industry and could speed the transition to a circular water economy.
“Sector-specific roadmaps gave us almost 90 different things we could focus on,” said Jordan Macknick, NREL’s lead energy-water-land analyst and NAWI’s topic-area lead for data, modeling, and analysis. “There’s no amount of money in the world that can address all those in one project in one coherent way.”
The master roadmap distills those 90 options into a smaller list of those with the greatest impact potential. One of those areas is cost.
Desalination devices that filter contaminants out of salt water or wastewater are not cheap. “We’re currently using these very big bulk separation technologies, like reverse osmosis, which use a lot of energy and are also very expensive, to remove trace contaminants,” Macknick said. “It’s almost like you’re using a sledgehammer to put a tack in a bulletin board.”
He and the broader NAWI team are researching ways to extract contaminants faster, cheaper, and smarter. For example, bulk separation technologies are not necessary to extract microscopic contaminants, like selenium or boron. Smaller, more precise technologies could perform the same job for less money and energy input.
Their goal is something called pipe parity. In Denver, Colorado, for example, if traditional water sources run out, what happens then? The city could pump water over the mountains, but that method gets expensive fast. If the NAWI team can design technology that makes recycled water the cheapest back-up option, that is a win.
But cost is not the only barrier.
“The traditionally conservative water industry is understandably risk averse,” Macknick said. “In general, that’s a good thing for our health. But it also makes the pace of innovation more challenging.” To incentivize the water industry to incorporate nontraditional water sources into their current infrastructure, Macknick and the cross-institutional team need to bring the costs down but also ensure the science is “bulletproof,” Macknick said.
And the water industry is not the only group that needs some convincing. Some consumers still balk at the idea of drinking recycled water.
“There’s a major perception issue when we talk about recycling or reusing water that, somehow, it’s not clean enough or as pure as the water we might get from a river and treat, when in fact, we’re oftentimes treating it to a higher standard than the water that we might pull directly from a river,” Macknick said.
Changing perceptions might take time, but, in the meantime, NREL can help speed the development of more efficient, cost-effective technologies that edge recycled water closer to widespread use. No single technologic breakthrough will get the job done; water treatment often uses a dozen different processes strung together. But with NREL’s deep knowledge of systems analysis, the laboratory’s researchers can analyze these processes as a whole and determine which changes might have the biggest impact.
NREL also previously led the development of an analytical tool called the Water Technoeconomic Assessment Pipe-Parity Platform (Water-TAP3), which evaluates water technology costs, energy use, environmental impacts, and resiliency trade-offs. NREL researchers also developed a data repository called the Water Data Analysis and Management System (Water DAMS), a national go-to for water technology and treatment data. And the laboratory does not just collect and analyze data. NREL’s advanced manufacturing researchers can help design entirely new materials to extract contaminants with greater speed and reduced cost.
NAWI’s new master roadmap will help guide future research at NREL and beyond. “The master roadmap is what is guiding our future investments,” Macknick said. “As the field advances, not only in the United States and with NAWI but also internationally, we want it to be a living document that changes as the sector advances and adapts.”
New technology, developed with guidance from the NAWI master roadmap, could allow farmers to reuse wastewater and even some of its extracted contaminants — phosphorous and nitrogen — as fertilizer. As climate change incites more droughts, wildfires, and extreme heat waves, farmers and ranchers could stay afloat with unconventional water sources.
Despite its name, wastewater need not be wasted.

Lectric launches new and improved XP Trike2 with $227 in free gear for preorder at $1,499
As part of Lectric’s newly launched Better Than Prime Sale, the brand is offering preorder savings on its all-new XP Trike2 that comes with $227 in free gear at $1,499 shipped, while the upgraded 750 model won’t be available for preorder until September. This bundle would normally cost $1,726 in full, but as most folks know, the brand tends to provide discounts on the bundled items over actual price cuts. This all-new commuting solution is getting the first chance at savings through July 28th, when it is slated to begin shipping. Along with the eTrike, you’ll be getting a wider saddle with a supporting backrest, an Elite headlight, and a suspension seat post. Head below to learn more about this model and its upcoming 750 variant too.
The next generation of one of the most popular eTrikes on the market, especially amongst older riders, Lectric’s new XP Trike2 cruises onto the scene with a Stealth M24 500W rear hub motor (peaking at 1,092W) that runs quieter than normal motors, as well as a 624Wh battery. This combination provides top speeds of 14 MPH and a travel range of up to 50 miles on a single charge when the five PAS levels are activated. If you haven’t ridden in a while and want to take things slow, there is a power-limiting preset feature that dials down its max speed until you’re ready.
There’s a bunch of notable upgrades coming with the Lectric XP Trike2, like the Cloud 50 suspension fork to take pressure off your joints, as well as hydraulic brakes for guaranteed stopping power, a headlight and taillight that provides amber side lighting, turn signals, brake lighting, plus reflective tires – all in the name of keeping you seen and safe. You’ll also be getting puncture-resistant tires with fenders over each, a 20A internal controller with an IPX5 water-resistance rating, parking brakes, a rear cargo rack with a 75-pound payload, a half-twist throttle, a new TFT LCD display, keyless riding functionality, and more.
Now, if you want to hold off for the upgraded Lectric XP Trike2 750 model, there are a few key differences to consider. First, it will be available at $1,799 shipped come September, with a larger 840Wh battery and Stealth M24 750W rear hub motor (peaking at 1,310W) that provide increased 17 MPH top speeds and a travel range up to 70 miles with the pedal assistance activated. From there, the big changeup comes from the inclusion of the brand’s Quick Switch tech that allows you to switch between cadence and torque sensors.

Get $2,200+ savings on Greenworks’ 60V Crossover-Z riding mower with six 8Ah batteries at a new $2,797 low
As part of its Prime Day Competitor Sale, Walmart is offering the best pricing yet on the Greenworks 60V Crossover-Z 42-inch Cordless Zero Turn Riding Lawn Mower with six 8Ah batteries and three dual port turbo chargers at $2,797 shipped. Normally, this package would run you $5,600 direct from the brand’s website, where it’s currently marked down to $5,319, but fetches $4,997 at Walmart. The already significant difference in price only gets better with the $2,200 markdown we’re seeing during this sale that beats out all the pricing we’ve seen up until today to land it at a new all-time low. You won’t find this package at Amazon, where only the bundle with four 8Ah batteries is offered – plus, that’s sitting nearly $1,000 higher in price, so you’re getting a lot more here for a lot less.

Ford has a new idea to help you save this summer: $0 down payment, 0% interest, and zero payments for the first 90 days. The new summer sales promo is available on most Ford and Lincoln models. Those buying an electric vehicle can also score a free home EV charger.
In April, Ford launched the “From America, For America” campaign, offering employee pricing to all. According to Ford, the offer helped make it the number one selling brand in America in the first half of 2025.
Despite the success, Ford is shaking it up for the second half of the year. Starting July 8, Ford is transitioning to its new “Zero, Zero, Zero” offer.
The summer sales promo features a $0 down payment, 0% interest for 48 months, and zero payments for the first 90 days on most Ford and Lincoln vehicles.
Although the employee pricing plan turned out to be a success, Ford dealers said buyers could benefit from less out-of-pocket expenses.
Those shopping for an EV can also score a free home charge. Ford extended its Power Promise program through September 30.
The program offers buyers a free Level 2 home charger (plus standard installation) and other perks like 24/7 live electric vehicle support, roadside assistance, and an 8-year, 100,000-mile battery warranty.
Despite strong overall sales in the second quarter, Ford’s EV sales fell by nearly a third. Ford spokesperson Martin Gunsberg told Electrek the lower EV sales were due to the Mustang Mach-E recall and changeover to the 2025 model year. “Our dealers can’t sell what they don’t have,” he said.
Although the Trump administration is ending the federal EV tax credit, you still have until September 30 to snag the savings on eligible models.
Ready to test one out for yourself? You can use our links below to find deals on the Mustang Mach-E and F-150 Lightning at a dealer near you.
