Chennai:
It was for more than two days Chennai was short of 135 MLD
treated water from Chembarambakkam Lake when a three tonne shutter in the
treatment plant collapsed, according to Metro water sources.
Metro water sources said that the shutter provided in the
Intake tower to control the water transferring into treatment plant fell down
on December 30 after the connecting shaft gave away.
As a result the treatment plan could not receive water from
the intake tower. This posed a huge challenge for metro water officials and
engineers. While Metro water immediately sought the help of water tankers to
supply water in south Chennai, top officials were working on several measures
on how to tackle the situation.
“For the next two days, efforts were on to restore the three
tonne shutter. Rectification of the shutter work was carried out by Metro Water
and Public Works Department officials,” said Metro water sources.
The biggest problem was the narrow working space besides 20
feet water level. This delayed the restoration work. Later skilled workers were
also engaged to lift the shutter but that also proved futile.
It was then, metro water sought the help of experienced sea
divers on the midnight of January 1, 2013. The divers using safety equipments
lifted the shutter and water was received at Chemabarambakkam Water treatment
plan, Metro Water sources said.
