CHENNAI: The ‘Sustainable Water security mission’, which was begun in Chennai, will be replicated across the State by the next financial year, says Phanindra Reddy, principal secretary, Municipal Administration and Water Supply Department.

He was speaking to the Express on the sidelines of the Water Conclave 2017. The sustainable water security mission that was launched by Jayalalithaa had five components: campus rain water harvesting; grey water recycling and reuse; storm water harvesting; restoration and rejuvenation of water bodies; and research, documentation and outreach.

SS Rajagopalan, former director, State Water Resources Management Agency and former chief engineer, Water Resources Department, said the State Water Policy was not renewed since 2002. Reddy reacted to it saying that while the policy remained on paper, sustainable water security mission would play the role of an action plan instead.

Around 280 water bodies were identified in Chennai, of which 32 were shortlisted for the project and a detailed report was prepared for four to five. Pilot projects were initiated for 15 water bodies.

“We’ve instructed each municipality to desilt and deepen reservoirs in their area without expecting extra Government funds,” he said. “Apart from cleaning natural reservoirs, we have extended the project to temple tanks,” he said. In Chennai, 17 temple tanks was identified to ensure that the tanks were replenished and cleaned and if there was no inflow of water, the reason would be analysed. “We have completed restoring two of these tanks,” he said.

Corporation to set up rainwater harvesting cell to disseminate information

| Updated: Mar 23, 2017, 01.00 AM IST

Madurai: With the city facing its worst water crisis in 142 years this year, the Madurai Corporation has decided to establish a rainwater harvesting cell, through which residents can get technical details on its setting up and maintenance, corporation commissioner, Sandeep Nanduri said on Wednesday. The cell would be set up in co-ordination with the Young Indians chapter of the CII (Confederation of Indian Industry) and Rainstock, an organisation into rainwater harvesting.

Nanduri was speaking at the 'World Water Day' event organised by the corporation at the Gandhi Museum campus in Madurai on Wednesday. He said that this was by far the most important event being conducted by the Madurai Corporation and the importance of conserving and saving water was a message that has to be taken to all.

Water awareness will be intensified in the city corporation limits in the next two months, before the next monsoon to harvest the rain, he said. While many houses having already established their own structures, as there is a government order which makes it mandatory, campus rainwater harvesting systems in large complexes and institutions are to be intensified, he said. These structures set up over a decade ago have to be maintained regularly, he added.

Collector K Veera Raghava Rao, who flagged off the World Water Day rally in which hundreds of students from many city colleges participated said that students of both schools and colleges in the districts should act as ambassadors of water conservation.

He urged the students to take the message on water conservation to all the 1946 hamlets in the district and said that the district administration was ready to help them in this initiative. The only solace is that this March, the district received four times more than its average rainfall, which helped it have water for an additional 15 days. "Just imagine what we would have to face if the failure of just two monsoons, led the district to face the worst drought in 142 years," he said.

Chairman, CII Madurai Zone P Srinivasavaradhan said that the CII would work in co-ordination with the district administration to maintain water bodies in the district.
 

City’s ground water very poor in quality, says survey

City’s ground water very poor in quality, says survey

| Updated: Mar 23, 2017, 01.00 AM IST

Madurai: The quality of the ground water, which is used for many purposes except drinking, in the city and its outskirts is fast degrading. While the total dissolved solids (TDS) was found to be high in deeper borewells, it was worse in shallower ones too, probably due to external contamination, reveals a survey on TDS in ground water, conducted by Rainstock, an organization working on rainwater harvesting, on the occasion of World Water Day.

Founder of Rainstock, K Sakthivel, said they had done the survey in various parts of the city for the past three weeks, and found that the TDS had increased many fold in some places when compared to the statistics obtained during a similar survey in 2015. According to the World Health Organisation (WHO), any TDS concentration below 1000 mg/litre is acceptable to be used by consumers. The Bureau of India Standards (BIS) has fixed the upper limit for drinking water at 500 ppm (parts per million). TDS comprises organic salts and small amounts of organic matter that are dissolved in water.

The members of the organisation had also engaged students in the survey and pamphlets and questionnaires were handed over to the residents, to find the depth of their residential bores and many of them had said that they had gone for deepening of their old wells, while many houses had said that they had multiple borewells in their homes to meet their needs.

Some places like Iravathanallur, Thiruparankundram, Kochadai, Pamban Nagar, among others had a ground water level, where water was available at 250 feet. Whereas in places like Gomathypuram, Aathikulam and Jahindpuram, which were in the vicinity of huge water bodies such as the Vandiyur tank, water was available beyond a depth of 450 feet. The TDS in Gomathypuram on an average was 1704 ppm.

Many residents of the city are prone to seeking residences in places where there is a good ground water table at around 250 to 300 feet, since it would ensure that they would not have to face a water crisis during drought periods. "But, the irony is, that in places where there is copious ground water, the TDS was seen to be hovering along the danger limit during our survey," Sakthivel said.

For example, in Iravathanallur where the average ground water level was 295 feet, the TDS stood at an alarming 1237 ppm. Though the survey had not gone into the individual elements in this water, Sakthivel says that many minerals could be harmful if they exceed the limit and that the high TDS is a result of contamination from external sources including open sewage.

Another example was Pamban Nagar, which is situated near the corporation dumping yard in Vellakkal, where the ground water was available at a depth of 170 feet, but the TDS was 2,960 way above the permissible level of 1000 ppm. Residents had told the survey team that there water had been good before the dumping yard was established. Though water is available at a very accessible depth these people get their drinking water from a place eight km away.

TDS levels in areas in - 2015 - 2017

K K Nagar - 405ppm - 1208 ppm

Thiruparankundram - 717ppm - 936 ppm
