Monday morning was again a difficult time for city residents with taps remaining dry and the work on replacing the burst main water pipeline continuing near Aruvikkara pumping station. The work on plugging the leak detected on Saturday night exceeded the set deadline of Sunday evening and again of Monday noon.
The excavation work that began on Saturday night was made difficult by the depth (of 4-5 metres) at which the 1,200-mm pre-stressed concrete pipe was laid and also the loose soil, Kerala Water Authority (KWA) officials said.
“Since we discovered a second rupture, we had to re-lay around 11.5 metres of the old concrete pipe with mild steel,” said the KWA Executive Engineer at Aruvikkara.
“We began welding by around 2.30 pm on Monday. This is a time-consuming process that should take about six hours,” he said.
Meanwhile, KWA was beseeched with requests from city-zens for the services of its water tankers. The Authority has eight tankers of varying capacities - 6,000 litres, 9,000 litres and 10,000 litres - under its various section offices in the city, officials said.
“Around 71 loads of water were sent on Sunday and 43 on Monday, as of late evening,” said the KWA Helpline Centre officials. “Private tankers have also been operating in certain areas,” they said.
Water was also diverted to the PTP Nagar tank and from there to Vellayambalam region from the new water treatment plant of JICA at Aruvikkara, said KWA Chief Engineer Sreekumaran Nair.
Several regions under the Peroorkada section also were supplied with water, said an Executive Engineer. Areas like Manvila, Powdikonam, Sreekariyam, Technopark and high-lying regions remained short of water even afterwards, he said.
