Coimbatore: The second phase of the Pilloor Drinking Water Supply scheme will be ready by mid 2010, said Collector P. Umanath and Corporation Commissioner Anshul Mishra here on Thursday.

They were talking to reporters at the Vellingadu water treatment plant about 45 to 50 km from here after inspecting the six packages of works under progress. Though the contract agreement period stretches up to September/October in all the six works, officials were confident of work being completed a few months ahead of schedule.

Once Pilloor II phase scheme was commissioned, Coimbatore Corporation would get about 200 mld.

At present, Siruvani scheme was getting about 65 to 70 mld per day while of the 120 mld withdrawn from Pilloor, the city was getting close to 65 mld.

When the dedicated Pilloor water supply scheme is commissioned, it would give 120 mld. The scheme has been designed in such a way that the infrastructure would hold good for the next 40 years.The supply of 65 mld drawn from the existing Pilloor water supply scheme would be then made available to the wayside habitations being served now and to 440-odd new habitations.The six packages of works included two pumping stations at Periyakombai Hills and Kattan hills and in other places the flow would be by gravity, officials said.

Regarding construction of overhead reservoirs, Mr. Anshul Mishra said that the work was being entrusted to consultants for deciding on the number of over head tanks, capacity and their locations.

Of the entire route length of 34.25 km, 9.4 km would be pre-stressed concrete pipes and the rest would be mild steel pipes.Once Pilloor scheme is commissioned, the dependency on Siruvani would come down to just 33 per cent, Mr. Mishra said.

Dr. Umanath and Mr. Mishra said that water level in Pilloor was comfortable and the storage in Siruvani scheme had improved to 870 ft as against the full reservoir level of 878.5 ft.

The reservoir area witnessed a rainfall of 115 mm, highest rainfall in the last one year. From a lowest of 864.9 ft, the storage had improved by more than 5 mts in the last two to three weeks.

With rainfall and inflow into the reservoirs continuing, officials said that if the rainfall level continued at the same rate the reservoir would surplus in the next 10 to 15 days.

Going hi-tech: The multi-purpose mobile van for testing drinking water and to detect water leaks. —

Tirupur: The corporation will commission the Rs. 15.36-lakh multi-purpose mobile van for testing the quality of drinking water and to locate leaks in water supply lines on June 24.

The van, named ’Blue Brigade’ and embedded with modern gadgets like water leak detector and a water testing laboratory, among others, is undergoing last-minute modifications before it starts rolling through the city roads. City Engineer K. Gautaman told ‘The Hindu’ that the water testing laboratory would be equipped with accoutrements to measure the level of total dissolved solids (TDS), turbidity and hardness at different points of distribution.

“This is to ensure that the residents will have access to high quality drinking water even at the tail-ends of distribution as any increase in TDS and hardness levels beyond the permissible limits set by the Central Public Health and Environmental Engineering Organisation can lead to gastro intestinal problems and skin irritations,” he said.

Regarding the portable water leak locator in the van, Mr. Gautaman said that it would be useful to locate and pinpoint leaks in buried pipelines, which were otherwise difficult to trace with conventional leak detecting methods. “This instrument comprising variable sensitivity and volume control panels provides both visual and audible indications to detect leak points,” he said.

A salient feature of the leak detector is that its sensitive ground microphone picks up vibrations caused by water leaking from the pipe which are strong and normally in the frequency range of 100 to 800 Hz.
