‘Chennai’s sewage generation 3 times that of official figure’

CHENNAI: How much sewage does Chennai actually generate? According to Arappor Iyakkam, a Chennai-based organisation, the city generates 1500 million litres of sewage a day (MLD), a figure that is three times more than what is stated by Chennai Metropolitan Water Supply and Sewerage Board (CMWSSB). Of this, only 427 MLD of sewage is being treated, the organisation said.

The citizens’ group claimed that the findings of the report titled ‘Why Chennai Stinks’ that was released on Wednesday, was based on a series of RTIs and inspections carried out by a team from the organisation. “The first step towards finding a solution for the sewage problem is to acknowledge it, something that the government is failing to do,” said  Jayaram Venkatesan, convenor of Arappor Iyakkam.Even by consolidating the data acquired from the CMWSSB, the team found that at least 604 MLD of sewage was being pumped in the 245 pumping stations across the city, revealing a difference of over 50 MLD with the CMWSSB estimates for 2017.

Out of the 27 sewage pumping stations that were audited for the study, the report alleged that 10 stations released untreated sewage into waterbodies. In the team’s social audit of pumping stations, no plant operator was reportedly assigned to several pumping stations like the South Mada street pumping station at Tiruvottriyur.

“There was only a field operator with high school education in most of the pumping stations that we audited, and the operator did not know even basic details like the measure of total flow of sewage,” Jayaram said. The operator’s work was limited to switching the motor on and off based on the level of sewage in the well.

A plant operator, on the other hand, is required to have an associated degree or diploma and keep himself updated on the functioning of the pumping station. At the stations, three operators are required during each shift - one plant operator and two field operators.
“There was even an instance when we found the operators drinking at the time of our visit,” he said. According to the report, at Manali, a large quantity of untreated sewage was let into a pond, called an ‘oxidation pond’, which had been apportioned near the Kosasthalaiyar, solely for the purpose of collecting untreated discharge. This was later verified through  RTI.

The report also detailed the team’s observations on  sewage treatment plants in the city, concluding that it lacked monitoring mechanisms like flow metres and had insufficient aeration. It also noted that the main equipment in many of these plants, including the primary clarifier and bio gas engine, were not functional.


The group has recommended the installation of automatic flow controllers to publish live data on sewage flow and holding the CMWSSB responsible for prevention of discharge of untreated sewage into waterbodies.

Corporation hopeful of maintaining water supply for a month

2,000 tanks to be installed at vantage locations to help in water distribution

The Corporation is hopeful of distributing water to the residents without difficulty till the first week of May, said Commissioner Sandeep Nanduri here on Wednesday.

Speaking to reporters, he said that despite the stoppage in the discharge from Periyar dam to the Vaigai reservoir, the storage level in Vaigai dam was around 25 feet which was expected to feed the residents for the next 30 days from today.

The infiltration wells at Melakkal, Kochadai, Manalur and Tiruppuvanam were expected to feed water beyond May first week, and the engineers have also identified spots for borewells, which would be dug up in as many as 200 points. “We have to supply potable water to the residents and will accord top priority towards this,” he responded when asked how they would face the opposition from people to the Corporation digging borewells in public places.


Summer showers

Above all, the summer showers, which is usually experienced by April-end, may bring in some relief. While drinking water provision would be in place for devotees visiting the city for the chitirai festival, the water for Lord Kallazhagar’s entry into the Vaigai river, would be made known at an appropriate time, he also added.

The Corporation has procured 2,000 water tanks, which would be installed at vantage locations, and water distribution would be done easily through this. The GPRS facility has been very useful and payments to contractors were being made only after verification with the logsheets in the modern control room at the Anna Maaligai, the Commissioner said.

"Also, we are having a dialogue with the industries and regulating their supplies," Satyagopal said adding that steps are being taken to tap drinking water by putting subsurface bags at places with adequate water resources.

Asked about the water situation in Chennai, Satyagopal said, "There will be regulations but we are confident that the supply of water will be steady." Besides, water tankers will be used to supply drinking water in areas that cannot be covered by the distribution system, Satyagopal told reporters on the sidelines of a summit on climate change & disaster risk reduction.
