Jwalo ka moetsi wa pele wa lehae wa mohala wa tlhahiso ya diphaephe tsa ho bokella madi, khamphani ya rona e dula e qapa dintho tse ntjha mme kamehla e boloka boemo bo etellang pele hara balekane ba lehae le ba kantle ho naha. Ho feta moo, mohala wa rona wa diphaephe tsa ho bokella madi o etsa hoo e ka bang 80% ya mmaraka wa lehae, mme ho ka thwe o na le monyetla o moholo ka ho feletseng. Mme matjhabeng, mela ya rona e rometswe Russia, Latvia, India, Turkey, Bangladesh, Kazakhstan, Saudi Arabia, United Arab Emirates le dinaheng tse ding. Ho fihlela jwale, IVEN e se e fane ka disete tse makgolo tsa disebediswa tsa meriana le disebediswa tsa bongaka dinaheng tse fetang 40. Mme palo ya mela ya ho bokella madi e rekiswang kantle ho naha e fetile 30. Dinaheng tse ngata, mela ya rona ya tlhahiso e na le melemo e felletseng, e nkang karolo e ka bang 90% -100% ya karolo ya mmaraka. Nakong ya dilemo tsena tsa ho romela kantle ho naha, re na le boiphihlelo bo bongata mebarakeng ya lefatshe ka bophara, mohala wa tlhahiso ya pokello ya madi a vacuum le wona o ile wa ananelwa haholo ke bareki ba rona ba tshepahalang le ba tshepahalang. Ho feta moo, re thehile botumo bo botle mmarakeng wa Matjhaba butle-butle.
