BMC marks out no-digging zone around water tunnel

After an arterial, large-volume water tunnel at Malad was punctured while an illegal borewell was being dug, the Brihanmumbai Municipal Corporation (BMC) is readying regulation to prevent a repeat.

It has prepared a circular banning borewell digging in the tunnel zone plus a buffer zone of 100 mtr – comprising 50 mtr on either side of the tunnel.

“For any request to dig a borewell, the ward office will have to first ensure the digging spot is not in the tunnel zone or the buffer zone,” said Vinay Deshpande, chief engineer, Hydraulic Department.

Water department officials said repairs on the Malad tunnel breach could take more than five days to complete since they haven’t yet located the damaged portion. “The area where the tunnel was punctured will have to re-excavated, so we can get a camera inside and understand the exact extent of damage,” said Vinay Deshpande, chief hydraulic engineer.

The breach occurred on February 14 on the Malad Marve Road, during the digging of a borewell inside the compound of an under-construction one-storied structure.

The 12-km tunnel, running from Liberty Garden to Charkop, supplies water to Malad, Goregaon, Kandivli and Jogeshwari, and is around 80 feet below the ground.

Water supply from Malad to Borivli will be affected for those five days, and pressure is expected to be minimal even after the work is complete.

“We hardly got water for 15 minutes today, that too at minimum pressure,” said Borivili housewife Harsha Joglekar. The two men arrested for the unauthorised digging, Vilas Kadam and Jagdish Talreja, were released on bail.

“The estimated Rs 25 lakh repair bill will be sent to the accused,” said Standing Committee Chairman Ravindra Waikar.

City teeters on brink of water crisis

Summer’s early arrival has brought with it the municipality’s most urgent challenge – how to manage its water stocks to last until July 15, when the monsoon hopefully breaks over the city.

On March 2, water stock in the city’s six lakes was 4.57 lakh million litres, which is far lower than the 6.68 lakh million litres that we had during the same time last year.

With the Irrigation department releasing more water to Mumbai from the two state-owned dams, Bhatsa and Upper Vaitarna, the BMC now supplies 2,900 million litres of water daily (MLD).

Due to deficient rainfall, reserves in dams supplying water to the city are depleting. A 15 per cent water cut is already in place across the city, and civic officials fear that may increase if our water position does not improve soon.

The BMC will begin artificial rainfall seeding in May. Agni Aviation, which was contracted for the exercise last monsoon, has been re-appointed.

Dy. Mayor defends alternate day water supply

Dorabbayee says the practice is being resorted to prevent crisis in future

 


At present the city has been receiving 50 mgd of water, says Dorabbayee

‘Demand for drinking water has gone up after merger of 32 villages with GVMC’


VISAKHAPATNAM: The water levels in Raiwada, Thatipudi, Yeleru and Meghadrigedda Reservoirs are at their lowest with only about 10 to 15 per cent availability of storage capacity available in them at the moment. The supply of water on alternate days has been resorted to avoid drinking water crisis in future, said Deputy Mayor Kotharu Dorabbayee.

Addressing a media conference here on Tuesday, he said at present the city was receiving 50 mgd (Million Gallons/ Day) which includes 28 mgd from Godavari, 13 mgd from Raiwada and six mgd from Thatipudi Reservoir. Of the 50 mgd, 10 mgd was being supplied to meet industrial needs, while the remaining 40 mgd water was being supplied to meet the drinking water needs of the city. The alternate day supply of one hour would ensure that the available water resources could be used till April-end.

Mr. Dorabbayee said daily water supply could be restored if the city received a few spells of rain in between. He felt that the suggestions being made in some quarters that instead of alternate day supply for an hour, the supply could be made daily for half-an-hour, were not feasible. Line discharges and wastage could be minimised if water was given for one hour at a stretch, he said.

He said the demand for drinking water has increased after the merger of 32 villages in Greater Visakhapatnam Municipal Corporation (GVMC). It would go up further with the population of the city projected to reach 30 lakhs by 2020 due to large-scale migration as a result of the proposed petro corridor complex and IT hubs.

Referring to the release of 175 cusecs of water to farmers from the Raiwada Reservoir from February 26, the Deputy Mayor said he had written to the District Collector seeking a temporary reduction in the supply for irrigation as it would result in a drastic fall in the water level in the reservoir and thereby affect the drinking water supply to the city.

Mr. Dorabbayee said the GVMC had proposed Rs.14 crores for repair of bore wells and public taps under the Summer Action Plan. The approval of the State Government was awaited in this regard.

Replying to queries, he said 10 per cent of the 6,000 borewells in the city needed repairs and an additional 265 bore wells were sanctioned this year. He said DPRs (Detailed Project Reports) were sought for a laying of a pipeline for bringing Godavari water to the city with about Rs.1,000 crores and for the Raiwada pipeline with Rs.200 crores to meet the future water needs of the city.

He said de-silting at Mudasorlova Reservoir would be regulated and in other reservoirs it had to be taken up by the Irrigation Department.

Chief Engineer B. Jayarami Reddy, Superintending Engineer V. Chandrayya and Corporator Hanumantha Rao were also present at the media conference.

Contingency plan to be chalked out

 


Collector reviews water supply, demand position with officials

Villages prone to drinking water shortage to be identified


NALGONDA: The district administration has mooted a contingency plan to check drinking water scarcity and ensure adequate supply of drinking water in the rural and urban areas in the district during the ensuing summer.

Collector S. A. M. Rizvi has reviewed the status of drinking water schemes and chalked out arrangements for meeting the drinking water requirements during summer with the officials concerned at a meeting held here on Tuesday.

Addressing the meeting, Mr. Rizvi asked the allied government departments and agencies to work in tandem and formulate comprehensive action plans for proper supply of drinking water till the end of summer.

He directed the municipal officials to remove illegal motors if any from the Pedda Devulapalli Cheruvu, the main drinking water source for Miryalaguda town, and take appropriate steps for preventing drinking water shortage during the next 4 months.

Requirement

The civic officials of Bhongir municipality informed the Collector that the town was receiving 30 lakh litres of drinking water from Sainikpuri metro water works as against the total requirement of 60 lakh litres per day. The remaining quantum of drinking water is being tapped from power bore wells and two open wells in the town, they said.

The Collector asked them to ensure early completion of the four overhead tanks under construction in the town.

The Suryapet municipal officials exuded confidence that the present water level at Anajipuram Cheruvu would meet the drinking water needs of the residents of the town for around 198 days.

The Nalgonda civic officials expressed their preparedness to meet the drinking water needs of the town to the tune of 180 lakh litres per day till August.

The Collector asked the Rural Water Supply officials to identify the villages prone to drinking water shortage division wise and utilise the funds earmarked for transportation of drinking water through tankers.
