The back-wash agitates and dislodges the sand particles in the formation. When water level in the well goes below and air starts escaping through discharge pipe the air valve is turned to activate air lift pump assembly. The pumping starts and sand and water is pumped out. The process is repeated till the well is developed thoroughly.
