As the faultlines have been seen along with the proposed route of the Canterbury's River Project of Hydro-electric Tunnel, it has immediately persuaded the authorities for the redesign of the same.
It is to be mentioned here that the power project was granted the access last month, under which it can use the water from the Lake Waitaki for the $1 billion worth North Bank Tunnel Project, but what has happened is the plan hit a hurdle when the tests have recently revealed that there are issues with the geological structure of the tunnel.
It is to be mentioned here that Meridian spokeswoman Claire Shaw recently said that drilling along the faulted rock makes the entire process of making a tunnel much more difficult and hence it would take much more time.
Moreover, the spokesperson also said that in this case, the kind of risks involves will be much higher.
While it is still early days to figure how much would the redesigning of the tunnel would cost but it is certain that the billion dollar project is a one of the most important to the company.
