BWSSB, former mayor stresses on use of recycled water

BANGALORE: P R Ramesh, former mayor of Bangalore recommended that the government, BWSSB and BBMP should stop imposing rain water harvesting on citizens but channelize rain water through storm water drains to tanks and lakes and rejuvenate the water catchment areas of Bangalore.

"It is only 20% of the water that we consume while BWSSB pumps 1200 MLD of water everyday for the city spending thousands of crores. Tertiary and secondary treated water should be used for non potable purposes. The argument that it is sewage water which is treated fails because even Cauvery water which is pumped is also treated and sent," said Ramesh.

He criticized the government for thinking to meet the present crisis and then sit back and leave the city at the mercy of rains. "The government should think beyond Cauvery'. Is there a way to tap other sources like Nethravathy or Hemavathy. How can ground water table be replenished should be the main concern for the water board and government. They should also remove all encroachments around catchment areas or lakes," he added.

Meanwhile, the BWSSB chief Gaurav Gupta also stressed on creating mass awareness for using recycled and treated water. At the workshop organized in the board based on the MoU signed with Singapore on tertiary treatment, he said, "We need specific plans for developing capabilities to use treated sewage as a sustainable source of water. We have to emulate Singapore and other countries on loss reduction and leakage control of water".

BWSSB is sharing technological knowledge on developing capabilities for alternate sources of water through recycle and reuse of reclaimed water. The understanding was made on October 9, 2012.

Technical issues related to feasibility are being discussed in the four-day workshop and how to tap various means to educate the public with the involvement of the NGOs.

BWSSB seeks S'pore help in recycling waste water

Bangalore Water Supply & Sewerage Board (BWSSB), on Monday, called upon team of Singapore officials to prepare an action plan to successfully implement the recycle and reuse reclaimed water in Bangalore.

At a joint workshop with Singapore Cooperation Enterprise, on ways to reduce losses and leakage control, BWSSB Chairman Gaurav Gupta exhorted Singapore officials to provide “specific plans for developing capabilities to use treated sewage as a sustainable source of water.”

Further, he said, in a press note, that it was necessary to carry out public out-reach programmes six months before the implementation of recycle and reuse project.

“People have accepted the concept of recycle and reuse of reclaimed water to some extent and it is feasible. We have to work on safety measures that are to be implemented before undertaking the project,” Gupta said.

BWSSB and Singapore Co- operative Enterprise had entered into a Memorandum of Understanding for developing capabilities for alternate sources of water through recycle and reuse of reclaimed water for Bangalore on October 9, 2012.

Under this three workshops, two in Bangalore and one in Singapore, have already been conducted, educating BWSSB officials about the various aspects of recycling and reusing of the used water.

Another workshop is currently on in City, wherein technical issues related to feasibility report is being discussed besides exploring various means to educate the public with the involvement of NGOs on the issue.

Decks cleared for STP at Autonagar

G.V.R. Subba Rao

MBBR technology to be used for construction of the plant

A first of its kind Sewerage Treatment Plant (STP) will come up at Autonagar in the city shortly. The Vijayawada Municipal Corporation (VMC) has cleared decks for construction of the STP with Moving Bed Biofilm Reactor (MBBR) technology.

The STP is estimated to cost Rs.10 crore and will cater to the needs of 90,000 people in and around Autonagar. The corporation will invite tenders shortly for construction of the STP with a capacity of 10 MLD. The proposed STP is one of the treatment plants taken up under the Jawaharlal Nehru National Urban Renewal Mission (JNNURM) programme in the city.

Unlike other STPs where anaerobic process is involved, the MBBR uses aerobic process. Hitherto, the VMC had constructed the STPs with Upflow Anaerobic Sludge Blanket (UASB) technology. The new method makes it possible to attain good efficiency results of disposal with low energy consumption and the process is used for the removal of organic substances.

The biological oxygen demand has to be less than 30 to meet the national standards. These standards could be met with the MBBR technology. The STP is cost-effective, efficient, environment friendly and will bring down expenditure on the power and maintenance, according to officials.

The VMC will construct four STPs and six sump-cum-pump houses under the JNNURM programme in the city. The corporation has planned to construct two STPs at Jakkampudi and another two at Ajithsingh Nagar. The VMC constructed a 40 MLD STP at Ajitsingh Nagar replacing a 27 MLD STP constructed decades ago.

Another two STPs, each with a capacity of 20 MLD, have been taken up under the JNNURM. A 20 MLD STP at Ramalingeswara Nagar has already been completed, while an STP at Jakkampudi is nearing completion, and remaining are in different stages. The works have come to a grinding halt ever since the government froze the release of funds.

DDA told to remove rubbish from Yamuna bed by July 17

While hearing the case of Manoj Misra against the Union of India over dumping of debris on the Yamuna river bed, a five-member bench headed by NGT chairperson Swatanter Kumar also observed that affidavits submitted by government departments and Delhi Metro stating how much debris had been dumped by each of them and what had been done to remove it from the riverbed were incorrect.

"Affidavits on behalf of the public authorities including DDA, PWD, CPWD, DMRC, state of Uttar Pradesh and different corporations have been filed and we have no hesitation in noticing that these affidavits are entirely incorrect and do not comply with the directions contained in our orders," the order says.

The court has now asked all heads of department including the vice-chairman of DDA, directors general of CPWD and PWD, chief secretaries of UP and Delhi and municipal commissioners of Delhi to file fresh affidavits stating how much debris, construction and demolition waste has been generated by each agency in the last 10 years, where this debris has been dumped as per the their contracts and a list of contractors hired by these authorities who have worked on different projects and the payments made to each.

The affidavits are to include steps taken for removal of the debris till May 23 and the extent of removal of debris till the next date of hearing on July 17. The affidavits are to be submitted in court within the next six weeks.
