With the Middle Vaitarna dam project delayed by two years,BMC will now have to spend Rs 144 crore more on the construction of the tunnel which supplies water from the dam to the city. The tunnel from Gundavali to Kapurbavdi is one of the two underground tunnels from Middle Vaitarna.
The cost of constructing the Gindavali-Kapurbavdi tunnel has gone up from Rs 1398.76 crore to Rs 1543.2 crore with an increase in Rs 144.45 crore. The hydraulic department attributed this increase to the rise in cost of raw materials. The total cost of the dam project now stands at Rs 3031.71 crore. The delay in the dam project has caused the price escalation. We will now have to pay more for raw materials like cement,iron plates,fuel,electricity and machinery. The cost of labour has also risen, said Ramesh Bamble,chief hydraulic engineer.
Citing inflation as the reason,the hydraulic department will present a proposal for the increase before the civic standing committee on Wednesday. The construction of the 6.8 km-stretch tunnel started in November 2009.
Till April 2013,5.3 km was completed,said the department. Work on the underground tunnel is expected to be completed by April 2014,informed the department.
The other underground tunnel extending from the dam stretches from Kapurbavdi to Bhandup Complex. The total cost of the two tunnels is Rs 2887.26 crore.
Work on a 50 metre-high bridge at Middle Vaitarna dam was completed last month. After being delayed several times,the Public Works Department (PWD) completed it in five years. PWD was given the task of rebuilding the British-era bridge across the Vaitarna. The old structures height was 20 metre. It had to be replaced so that it does not get submerged once the dam is operational.
The Middle Vaitarna after completion is expected to bring 450 million litres of water to the city.
