Schemes to provide potable water for fluoride-hit villages

Lift irrigation schemes for 38 villages on uplands



KADAPA: Inclined sliding pumps, developed with the latest technology, will be introduced for the first time in the State in Brahmamsagar and Mylavaram comprehensive protected water schemes, Superintending Engineer of Rural Water Supply B. Rajendra Prasad said on Tuesday.

Under the new technology, two parallel rails would be erected alongside the dam inclination and the pumps can be manually moved from a higher to lower plane and vice-versa, depending upon the rise and fall in water levels in the reservoirs, the SE told The Hindu.

The technology was being introduced first in Kadapa district to pump potable water to about 100 fluoride-affected villages, the official said.

RWS has forwarded proposals for the State Government’s approval to supply drinking water from Jharikona medium irrigation project to villages in Chinnamandem and Sambepalle mandals in Rayachoti constituency and it was under investigation, Mr. Rajendra Prasad said.

Similarly, two other CPWS schemes to pump drinking water from Telugu Ganga subsidiary reservoir I to villages in Duvvur mandal and subsidiary reservoir II to villages in Mydukur mandal, both costing Rs. 31 crore, were also forwarded for the Government’s approval, he explained.

The schemes envisaged supply of potable water to fluoride-hit villages.

Tenders called for

Tenders were called for a CPWS scheme for Pulivendula and 99 villages with an outlay of Rs. 14.40 crore, but the first call received no response, the SE stated.

The scheme was originally designed to cover 137 villages and 99 would be taken up in the first phase. The remaining 38 villages were uplands and they would be taken up through lift-irrigation subsequently.

A CPWS scheme to cover Lakkireddipalle and 432 habitations in three mandals of Lakkireddipalle constituency, costing Rs. 39 crore, was awaiting forest clearance.

Two infiltration wells, collection well and a foot bridge were completed and gallery lines connected already. Perforated pipes were laid at a depth of 14 metres to ensure that clean groundwater was supplied for drinking purposes, he said.

Lakkireddipalle and 432 habitations required seven million litres per day (MLD) but 12 MLD of water was available.

Other ongoing CPWS schemes at Muddanur (Rs. 7 crore) from Galeru Nagari Sujala Sravanthi backwaters, Mylavaram, Mydukur, Pullampet from Annamayya project backwaters and Rollamadugu in Lakkireddipalle (Rs. 8 crore each), Badvel from Brahmamsagar reservoir (Rs. 18 crore) were affected due to rise in reservoir levels on account of recent heavy rains, Mr. Rajendra Prasad said.

They were slated for completion between December 2007 and April 2008, but would be delayed, the SE added.
