The southern sectors of Chandigarh are not conducive to the installation of tubewells as these become defunct within two to three years. Rather than water,these start drawing out sand. This is in contrast to the northern sectors,where tubewells have proven more successful. The Municipal Corporation (MC) is now contemplating the installation of tubewells only in the northern sectors.

The city receives 87 million gallons daily (mgd) water,of which 20 mgd is through tubewells. However,it has been found that the tubewells that are installed in the southern sectors are lacking in output.

There are around 200 tubewells in the city and every year 10 per cent of these become defunct. The rate is higher in the southern sectors.

More canal water is being supplied to the southern sectors than water from tubewells. Around 70 per cent of those installed are now defunct.

In a recently prepared report,MC officials stated that the water level is falling by 1.5 to 2.5 metres per year. Concern has been expressed at this fast depleting level. The sediments are coarser in the northern part and towards the south,the sediments grade into finer material.

Superintending Engineer (Public Health) R C Diwan said,“In the northern sectors,the quality of water drawn from the tubewells is better. In the southern sectors the tubewells become defunct,with there being a difference in the quality of soil between the northern and southern parts of the city. Since the number of tubewells cannot be increased,we are contemplating that the tubewells that are to be installed in lieu of those that are defunct should be in the northern sectors.”
