WELL TROUBLES

Failure of the well or reduction in the yield is not uncommon.

Following may be the reason and remedies.

• Reduction of discharge may be due to a draft greater than the percolation of water.
• Lowering the pumps may increase the yield for the time being, but permanent remedy is to reduce pumpage.
• The casing pipe or screen pipe may have collapsed, partially or completely, blocking the flow of water.
• This trouble necessitates replacement of the casing or screen pipes.
• If the material in which the well is drilled is unconsolidated it may have to be abandoned.
• Casing pipe may have corroded or leaked.
• Due to this, water may escape out into the ground or contaminated ground water may enter the well.
• The remedy lies in withdrawing and replacing the casing pipe.
• The life of the casing pipe depends upon the character of water handled by it.
• If water being handled is highly corrosive, C.I. or concrete casing may be used.
• Screens cause trouble by corrosion or incrustation.
• There is little that can be done about corrosion, but some remedies are available against incrustation.
• All forms of incrustation are remedied by acid treatment.
