10-mld treatment plant in Kallara panchayat

A 10 million litres a day (mld) drinking water treatment plant (WTP), which will serve nearly two lakh people in five grama panchayats spread across two Assembly constituencies, was commissioned on Wednesday, after a wait of nearly 20 years.

The treatment plant forms the axis for two major drinking water supply projects, one launched in 1991 and the other, in 1998.

The projects — the Kallara-Pangode Accelerated Rural Water Supply Scheme (ARWSS) in the Vamanapuram Assembly Constituency, and the Panavoor-Pullampara-Vembayam ARWSS in the Nedumangadu Assembly Constituency — were also inaugurated on the day. Both will be served by the 10-mld plant at Thengumkode in Kallara grama panchayat and a pump-house at Aruvippuram, with water drawn from the Vamanapuram river.

Water Resources Minister P.J. Joseph inaugurated the schemes.

The Kallara-Pangode scheme will ensure piped water supply to 74,500 people while the Panavoor-Pullampara-Vembayam ARWSS will benefit 92,750 people.

The Kallara-Pangode scheme, launched in 1998, will see water from the Vamanapuram river drawn by a pump-house at Aruvippuram of Pullampara grama panchayat and pumped to the treatment plant at Thengumkode.

New distribution lines

Treated water from the plant will reach a 14 lakh-litre overhead tank at Kodithookikunnu, from where it will be distributed through existing pipelines in Kallara and Pangode grama panchayats.

A 17-km new distribution network was laid here, apart from installing 35 public taps, while work on laying another 37-km network for areas that currently do not have a distribution system is in progress.

Sanction for phase II

The second phase of this scheme, which comprises a Rs.8 crore-project to install pipelines for another 125km in the two grama panchayats, had also been sanctioned by the government, the Minister said on the occasion.

The Panavoor-Pullampara-Vembayam ARWSS, envisaged in 1991, was launched in 1998 under the Centre’s ARWSS. However, work came to a standstill when funds from the Centre dried up. Work was revived a few years ago and a few final touches, including work on a 35km-distribution network in Vembayam grama panchayat, were progressing, the KWA officials said, adding that Rs.15 crore had been spent on this project so far.

Quality of pipes

Mr. Joseph, inaugurating the projects at functions organised at the Kanyakulangara Junction and on the WTP premises at Thengumkode, also said the government had decided to insist on the use of quality pipes instead of concrete or asbestos pipes for laying distribution networks, so as to do away with the recurring problem of pipe-bursts.

Koliyakode Krishnan Nair, MLA, presided over the function at Thengumkode, while Palode Ravi, MLA, presided over the function at Kanyakulangara Junction.

Ashok Kumar Singh, Managing Director, Kerala Water Authority (KWA), T. Subran, Technical Member, KWA, presidents of the five panchayats and other public representatives and officials of the KWA were present.

Malkapur gets Rs 40 crore funds for sewage treatment

KOLHAPUR: The Union government has sanctioned Rs 40.91 crore for the sewage treatment plan of Malkapur Municipal Council, the hometown of chief minister Prithviraj Chavan. His aide and deputy chairman of the council Manohar Shinde said the council was among the first five in the country to receive such a sanction from the Centre.

Shinde said, "The scheme includes laying down a 59-km network of drainage pipelines in Malkapur town. The work would be completed in three years. The sewage would be treated and usable water would be supplied to the agricultural sector."

Of the total cost of the project, 70% would be borne by the Centre, while the remaining would be jointly borne by the state and the Malkapur municipal council, he added.

Shinde said the previous proposal of the scheme included treatment of sewage based only on the existing network of drainage pipelines. After discussions with the chief minister, we were told to revise our proposal, which was made to fit the norms of the Union government's Urban Infrastructure Development Scheme for Small and Medium towns (UIDSSMT). The scheme is the part of Jawaharlal Nehru National Urban Renewal Mission (JNNURM), which was launched on 3rd December 2005 with an investment of Rs 1 lakh crore, with a fixed seven-year period from 2005-06.

He added, "The topography of the town will help us. The design of the drainage pipeline network would be made to use the gravitational force to accumulate sewage at three locations across the town for treatment. It would save expenses on pumping as well as electricity charges."

Malkapur is a town located adjoining Karad on NH-4 in Satara district. The town had won a national-level award for its round-the-clock drinking water supply scheme.

KIADB to fund construction of sewage treatment plant

The Karnataka Industrial Areas Development Board (KIADB) has come forward to fund the construction of a 40-million litre sewage treatment plant (STP) near Devanahalli to meet the demand of more than 2,000 industries.

The project is coming up on six acres of KIADB land, at a cost of Rs 105 crore. According to an official of the Bangalore Water Supply and Sewerage Board (BWSSB), treated water will be supplied to Devanahalli industrial area from Raja canal STP, located close to Hebbal by laying pipes for a distance of about 18.5 km.

30 pc work complete

Thirty per cent of the work has already been completed and the project is likely to be finished by August 2014.

The industries in Devanahalli utilise the treated water and the effluents released by them will be treated at the proposed STP.

The demand for treated water has been increasing steadily in the City.

According to a recent survey conducted by the BWSSB, the industries located in Devanahalli, Doddaballapur, Nandi Hills and a power plant in Yelahanka together need around 35 ML of water per day. The Board is looking at the feasibility of meeting the demand.

Recently, a private consultant had approached the BWSSB with a proposal for supply of treated water for a golf course and a horticulture park coming up on 210 acres of land near Malur in Kolar district.

The entire project might require 1,200 ML of treated water per annum.

According to an official, the BWSSB has planned one more demand-supply survey of treated water and explore the feasibility of supplying water by laying pipes. Individual demand from industries will be assessed before chalking out a strategy for creating the necessary infrastructure on a cost sharing basis.

At present, the BWSSB has been maintaining 14 STPs which together have the capacity to treat 720 ML a day.

However, the Board has been able to treat around 530 ML a day of which 30 ML is being sold to Bengaluru International Airport, Aravind Mills, Wheel and Axle Plant, BEL etc.

Fluoride treatment plants in nine wards

Fluoride treatment plants in nine wards

The Bruhat Bangalore Mahanagara Palike (BBMP) will instal 1,000-litre-capacity fluoride treatment plants in nine wards of Yelahanka and Mahadevapura divisions.

The Palike decision comes after it discovered high fluoride and nitrate contents and total dissolved solids (TDS) in the underground water in the nine wards – Chowdeshwari Ward, Attur, Jakkur, Thanisandra, Hoodi, Anjaneya Palya, Hagadur, Varthur and Bellandur – while sinking borewells recently.

Moreover, the High Court had directed the civic authorities to provide potable water to citizens and set up water-filter plants in areas where water contamination is very high. The Palike resorted to sinking borewells as the water table had drastically dipped in these areas.

Nitrate and fluoride are often described as silent killers and slow poison. While fluoride can cause arthritis, osteoporosis and other bone-related ailments, high nitrate content can lead to blue-baby syndrome causing heart-related problems among children.

Nitrate occurs in ground water due to sewage. Most of the water bodies in these areas are highly contaminated because untreated effluents are let directly into them by many apartment dwellers.

“Borewells in Attur are going too deep, almost 1,000 feet, where the chances of fluoride content in water is always very high. Tests have confirmed that fluoride, TDS and nitrate are high in Attur. So, the Palike has floated a tender to set up a water treatment plant in my ward,” said Attur Corporator K N Geetha Shashikumar.

She said the lakes in the newly added wards of the BBMP were highly contaminated due to lack of underground sewerage lines. She said her ward has Attur Lake, spread over 84 acres, but it has dried up despite heavy rains this year. “There was little water due to rains this year, but it has dried up again. The water table has depleted so badly that we have to sink a borewell near Attur Lake and the water again is contaminated,” said the corporator.

Ahmedabad Municipal Corporation to reuse sewage water

AHMEDABAD: In a bid to save fresh water, the Ahmedabad Municipal Corporation has decided to use treated water of the sewage treatment plant to water its garden.

The AMC to reuse the sewerage water has decided to have a recycling plant for treatment of sewerage water. The capacity of the plant will be about 10000 liters per day and the same will be set up in Navrang garden.

Officials said the plant, with the capacity of 10,000 litres, will be installed in a small area of 20sqm. According to them, the biological oxygen demand in the water will be less than 10 milligrams per litre.

Officials said that untreated water will be brought in the tank and will be treated in three different tanks. First, solid particles will be separated from the water and then the cleaning process will start.

The AMC, which is using bore water to water the gardens, will not only save on the water, but will also save 40 units of power daily which will help save Rs 73,000 annually per garden. If successful, the AMC will implement the same project in the other 200 AMC gardens of the city.
