At the stated 150,000$ to irrigate 25 acres this is in no way viable.
At a guess this is generally viewed locally as rather pointless as you can store far more water with a simple earthen dam. Basically, the hard part is having water in the first place not storage.
In terms of efficiency, spraying water into dry winter air likely resulted in quite a lot of evaporation. Further 150,000 liters of water sounds like a lot but it’s about 1.5 inch of water across an acre. Which is why you would need dozens if not hundreds of them per farm.
