Metrowater to install new system to monitor water treatment

CHENNAI: Chennai Metrowater will soon float a tender to upgrade some of its facilities. The State government has already sanctioned funds for the project.

An order was issued recently by the Municipal Administration and Water Supply Department sanctioning Rs.7.75 crore for the project. Officials of Metrowater said Supervisory Control and Data Acquisition System (SCADA), a computer system to monitor the process, would be installed at the Surapet water treatment plant and Perungudi sewage treatment plant at a total cost of Rs.41.1 crore. The SCADA would help in monitoring the volume of water treated and pumped out to the pipeline and the quality of water treated and effluent quality. The water agency would also use the funds to procure 25 flow meters to be fixed at nine water distribution stations, including Vysarpadi, Choolaimedu and Mylapore, and water treatment plant at Kilpauk.

The flow meters would facilitate accounting the volume of water being pumped into the main pipeline for distribution and also check for loss of water enroute, an official said. Moreover, the training centre of Metrowater would also be provided with additional facilities, including hostel, at a cost of Rs.1.70 crore. The centre provides skill upgradation training to nearly 800 staff of various government agencies, including Tamil Nadu Water Supply and Drainage Board and MAWS department.

The project is expected to be completed in nine months, the official added.

Tirupur: 100 dyeing units get closure orders

Power supply to these units disconnected

They failed to comply with Supreme Court orders Consent order given to 13 CETPs

Tirupur: The Tamil Nadu Pollution Control Board (TNPCB) on Friday ordered closure of 100 dyeing units in the Tirupur knitwear cluster which failed to comply with the recent Supreme Court order pertaining to pollution caused by the dyeing units on River Noyyal. The power supply to these units was also disconnected.

TNPCB District Environmental Engineer R. Kannan told The Hindu that according to the Supreme Court ruling, the units which either failed to remit the fines imposed for polluting River Noyyal or those units which were members of Common Effluent Treatment Plants (CETPs) which failed to fit Zero Liquid Discharge (ZLD) system all before January 5 evening, should be closed.

The Supreme Court verdict was pronounced after hearing the Public Interest Litigation filed by ‘Noyyal River Ayacutdars Protection Association.’

The bench comprising Chief Justice K. G. Balakrishnan and Justice B. S. Chauhan observed that “Undoubtedly, there has been unabted pollution by the members of Tirupur Dyeing Factory Owners Association” and hence, “they were bound to meet the expenses of removing sludge in the river as well as cleaning of Orathupalayam dam.”

The court also asked the dyeing units to carry out further operations without polluting the river anymore. The TNPCB on Friday gave the consent order to operate 13 Common Effluent Treatment Plants (CETPs) set up in the cluster which had completed fitting ZLD system in it. But not given to six others.

India-Tamilnadu-Erode-Govt. urged to take up effluent treatment

Staff Reporter
It will help textile processing industry and agriculture
 

ERODE: Textile processing units have urged the State Government to take up effluent treatment.

In a letter to Chief Minister M. Karunanidhi, they have said that the government must come forward to take up the work because those involved in the trade would not be able to do so.

“More than 3,500 of the 5,000 persons involved in the trade operate with a capital as low as Rs. 50,000, for whom a treatment plan is impossible. And, given the state of textile industry, it is extremely difficult for processing units to set up treatment plant,” the association has reasoned.

It has said that the Rs. 1,000-crore required is not a big amount for the government that spends thousands and thousands of rupees to protect farmers’ and poor people’s interests.

Environment

The processing industries association has cited the environment angle to urge the government to set up a common effluent treatment plant and added that if the government was to implement the project it will help both the textile processing industry and agriculture.

India – Bangalore – BWSSB plans mega water treatment plant

BANGALORE: Bangalore Water Supply and Sewerage Board (BWSSB) will construct the country’s second biggest water treatment plant at Torekadanahalli (TK Halli) to supply drinking water to the city under Cauvery IV stage II phase project.

BWSSB will be supplying 500 million litres per day (MLD) under Cauvery IV stage II phase and the water treatment plant will have a capacity to purify 500 MLD of water. Delhi Jal Board has constructed three water treatment plants of 550 million litres capacity.

Raw water from Cauvery river will be pumped from Shiva Anicut to TK Halli, which is at a distance of 18.5 km, through open channel and steel pipeline. The water will be purified and treated at TK Halli and will be pumped to the city in three phases, after treatment.

Nine working pumps and five standby pumps of high pumping capacity will be installed at TK Halli, Harohalli and Tataguni to pump water to the city, which is 98 km away from TK Halli. These pumps will be regulated with the supervisory control and data acquisition system.

The water will be pumped to the city in a steel pipeline of diameter 2700 millimetre and the water will be directed to six different ground level reservoirs (GLR) that are to be constructed at Jambu Savari Dinne, Uttarahalli, Parappana Agrahara, Gandhi Krishi Vignan Kendra, OMBR and Hudi.

These GLRs will have a collective storing capacity of 147 million litres of water and will help in regulating and diverting water to different parts of the city through 40 GLRs that are already existing and nine GLRs that will be constructed with aid from Bangalore Development Authority at different parts of the city.

All the aforesaid works will be undertaken under Cauvery IV stage II phase and will be jointly funded by Japan government and state government.

One of the BWSSB officials said, “Some of these works are yet to commence. If everything goes according to the plan, they should be completed by the end of 2012.”
