You can still recycle frack water for use over and over again, which is increasingly common. By necessity water recycling has become a big business in the fracking industry.
"Sensing a chance for a big return, private-equity firms have invested more than $500 million into wastewater-disposal companies such as Solaris Water Midstream LLC, WaterBridge Resources LLC, Goodnight Midstream LLC and Oilfield Water Logistics LLC. There are roughly a dozen of these water-focused companies that analysts said could each be worth hundreds of millions of dollars. ... Some companies have a longer-term plan: recycling the wastewater to sell it back to drillers to reuse."
"The oil and gas industry is finding that less is more in the push to recycle water used in hydraulic fracturing. Slightly dirty water, it seems, does just as good a job as crystal clear when it comes to making an oil or gas well work. ... Until recently, many companies considered recycling too expensive or worried that using anything other than freshwater would reduce well output. But oil and gas companies are increasingly treating and reusing flowback water from wells, which unlike freshwater is very high in salt, with good results."
