Water filtration plant at Satpur to be revamped

NASHIK: The mechanical department of the Nashik Munciipal Corporation (NMC) has proposed to revamp the water filtration plant at Satpur at an estimated cost of Rs 13.09 lakh.

The plant has been operational for the last eight years and needs repair and maintenance at various levels. For the purpose, the mechanical department had prepared the proposal, which has been approved by the municipal commissioner.

The proposal include repairing the building of phase II of the filtration plant, colouring it and constructing a compound wall for it, fitting mesh over the chambers, a pipeline for liquid alum and other important works. An engineer of the department said that the works related to buildings inside the filtration plant, cleaning up of water tanks, etc., will be done through a contractor by inviting tenders.

"At present, there is only one pipeline for passing liquid alum for purifying water. If this pipeline gets chocked, then we will need to have another line as a standby as liquid alum is necessary for the purification process. Hence, we have included installation of a standby pipeline in the proposal," the engineer said.

"After getting the municipal commissioner's nod, we have to get the proposal approved at the next general body meeting. We will call for the tenders and get the work done before monsoon season starts," he added.

Desalination project mooted

It looks like there is an end in sight for the water and power problems of residents in Kumbalangi and Chellanam panchayats. A desalination plant for these pockets of West Kochi is in the pipeline.

 Proposed by a private company, the plant is expected to bring relief to the coastal panchayats where drinking water has been a burning issue for years.

According to sources the company would set up the plant at an estimated cost of `16 crore. The operation of the plant and distribution of water will be vested with the Kerala Water Authority.

The promoters also claimed that the plant would be eco-friendly. “It will function on conventional energy, available locally. It will be cost-effective too, with the  production cost per litre as low as 10 paise.

Drinking water will be produced through vapourisation of saline. The plant will be capable of producing 1 MLD (Million Litres per Day) of water,” said M P Sivadathan of the Kumbalangi Model Tourism Development Society.

 The plant will also generate around 2400 units of electricity. He said the Kerala Water Authority is likely to operate and take over the distribution of water produced at the plant. “Certain minerals will be added to the water produced at the plant to raise its quality to international standards,” said Sivadathan, who is a member of the committee constituted to look into the project.

 A similar project has been implemented at Ramanathapuram in Tamil Nadu which a team of officials of KWA and representatives of local bodies recently visited.

“The plant in Tamil Nadu is smaller in size compared to the one proposed for West Kochi.

A final decision regarding the project is to be taken at a meeting of KWA officials and representatives of Kumbalangi and Chellanam panchayats and other organisations in the region, in Thiruvamnanthapuram, on Wednesday,” he said.

Are you a nature lover but had to helplessly witness a lake getting encroached? If yes, and if you are willing to help the local authorities avert such a thing from happening again, then here’s your chance.

‘Adopt A Lake’ is a new initiative conceived by the Hyderabad Metropolitan Development Authority (HMDA) to save the  lakes with public participation.

“We had a draft memorandum of understanding (MOU), which was approved by the seventh Lake Protection Committee (LPC) whereby we agreed to invite expressions of interest (EOI) from willing stakeholders in this regard to have discussions on the MOU, and finalise it,” said Neerabh Kumar Prasad, HMDA metropolitan commissioner, at a press conference here on Wednesday.

At present 501 lakes have been identified in the erstwhile HUDA area, 176 of which  now fall in the Greater Hyderabad limits and the remaining in the metropolitan area. Further, in the entire HMDA area, 2,845 lakes have been identified apart from those  in the  aforementioned areas.

“This is an opportunity to all the concerned citizens to help us protect the lakes. This is a responsibility. The draft is for three years for now,” said Prasad. However, under this scheme, the maintenance expenditure will have to be borne by the interested person himself or herself. “We will help them mark the lakes up to its full tank level (FTL) boundaries and buffer zones, including its inlets and outlets, by constant vigil.”

Prasad explained that interested persons would have to assist the officials of HMDA, GHMC, irrigation and revenue departments in marking the FTL levels, buffer zones, inlet and outlet levels. But big water bodies like the Hussainsagar, Himayatsagar and Osmansagar are not up for adoption under this scheme.

“We decided to initiate this as several people from resident welfare associations, NGOs and corporate sector have expressed interest in conservation of lakes.” 

He warned that the scheme was simply meant for taking care of the lakes and not for their commercial exploitation. “No water should be drawn from the lakes and any construction of any sort is also prohibited. And the adopter cannot restrict access to anyone nor can lease the lake. It is merely a public service,” said the metropolitan commissioner. Only acknowledgment will be in the form of a small board which will be put up, stating that the person or organisation is maintaining it.

“We all know about the current scenario and the problems concerning the lakes. As of now, we are trying to prevent further encroachments and, under the scheme, we will also take up identification of all the encroachments of the lakes,” Prasad ascertained.

Persons interested in adopting lakes can apply online from Thursday on the HMDA website. The last date for sending in applications is May 31.  “After the expressions of interest (EOI) are submitted, we will discuss with them the nitty-gritty, including the financial aspects. Once a consensus is reached, we will sign the MOU,” Prasad said, adding that the current statistics of the lakes were on the satellite images, and topography maps provided by the Survey of India.

 

Desalination plant planned near Gopalpur

Desalination plant planned near Gopalpur

BERHAMPUR: A desalination plant that will convert seawater into potable one is being planned near Gopalpur in Ganjam district. The Indian Rare Earths Limited (IREL) has decided to install a 5-million litre per day (mld) capacity plant to meet the industrial and potable drinking water requirements for its Odisha Sands Complex (OSCOM) at Matikhala near Chhatrapur.

The Rs 112.90-crore project is scheduled to be completed by March 31, 2019, the Union minister of state for personnel, public grievances, pensions and prime minister's office V Narayanasamy told Rajya Sabha member Renubala Pradhan in a reply recently.

"The Bhaba Atomic Research Center (BARC) will set up the hybrid seawater desalination plant for the IREL. It will comprise 4.5-mld seawater reserve osmosis (SWRO) and 0.5 mld multi-effect distillations (MED) system for producing water," the minister said. "The project is intended to meet the industrial and potable drinking water requirements of OSCOM," the minister said.

The OSCOM is currently meeting its water requirement for industrial and drinking water purpose through the Rushikulya river water system at Madhapur, near Chhatrapur. The urban water supply department is currently supplying around 1.1 mld (0.4 mld for drinking water and 0.7 mld for industrial purpose) to the IREL unit, said executive engineer (Urban water supply),Berhampur P K Mohapatra.

Pradhan urged the IREL authorities to enhance the capacity of the proposed desalination plant and supply potable drinking water to some more areas including Chhatrapur town and some portions of Berhampur under its Corporate Social Responsibility (CSR) activities.

The Rushikulya river water system, which can yield around 20 mld water, is supplying to OSCOM, Berhampur University, Army Air Defence College and Berhampur town. Since water supply from all sources to Berhampur is not adequate, the town is reeling under acute shortage of drinking water, particularly during peak summer.

"When the IREL authorities increase the capacity of its proposed desalination plant and supply potable water to the periphery areas of the OSCOM and Berhampur, the town will get more potable water and scarcity of drinking water will be solved partially," Pradhan said.

 

MWTPs: Making even filthiest water absolutely drinking-fit!

MWTPs: Making even filthiest water absolutely drinking-fit!

During Shrawani mela, at haat-bazaars or congregations like the ones that happen at Morhabadi Ground almost every week many consume water served in small water pouches.

Not many know that the water in small pouches (not the one sponsored by Ranchi Municipal Corporation) might be originally resourced from drains, sea and even septic tanks.

But there is no need to worry. The water is absolutely drinking-fit.

The impure water is collected, processed and purified in the system mounted on a van- that is why it is mobile. The entire system is called Mobile Water Treatment Plant (MWPT). The treated water comes out from the machines in small packages, the packages which carries potable water.

The MWTPs move from places to places collecting contaminated water which is processed on the van and instantly made drinking-fit. The venture was rolled out in late 2011.

As of now there are five MWTPs in State working in Sahibganj, Ranchi, Garhwa, Dumka and Palamu.

“The entire purpose was to meet the water needs during disaster. We wanted to purify impure water even from sources like drains, sea or even from septic tanks,” said Shardendu Narayan, Chief Engineer, Public Health Engineering Department.

One might get upset discovering that the MWTPs uses drain water and even the septic tank water! Also one might wonder when the department talks of using the sea water. Since there is no possibility of sea water being available in State like ours, flanked by land from all sides.

Shardendu has answers to all these concerns.“The MWTPs are part of our contingency measure. During disasters people die even for a drop of water. We have to make them available drinking-fit water. Here you don’t have to care about the source of water. All you need is the water that is non-contaminated, fit for drinking- which is what MWTPs do. Even I would be willing to consume the purified drain water in case of emergencies,” he said.

Explaining the use of sea water he says that this has been done keeping in mind not only the State’s needs but country’s needs.

“States like West Bengal, Odisha are prone to Tsunamis, earthquakes and others disasters. Sea water has invaded residential areas in such states in pasts and (God forbid!) can hit in future. The MWTPs will be handy in purifying sea water in these situations,” he said.

May regions in Jharkhand are confronted with severe water crisis. Can the MWTPs be of any help in the situation?

“No,” says, Shardendu. “Ours is small venture for making available potable water during disaster. For fighting the current water crisis, enough number of handpumps are there, though they are defunct. Departments need to take steps to repair the defunct pumps.”

He however added that if the district administrations demanded for the services of MWTPs the departments was ready to consider it.
