"In order to prevent this happening again, we will be using a keep net whenever the penstock
valve needs to be opened to ensure no fish are released.
It all depends on stream size, penstock
length, and other variables.
A and Tunnel A had already been plugged with concrete after the accidental discharge of sediment on Aug.
The proposed generating station includes a dam with a water intake and penstock
, powerhouse and tailrace channel.
"Philex is already rehabilitating and strengthening the existing tailings pond and has commenced the construction of an open spillway, which will replace the existing penstock
system for water management," Philex president and COO Eulalio B.
The company is backed by proven, world-class technology for direct bury, slipline, penstock
and microtunneling projects, and all products pass rigid quality control procedures to meet or exceed ASTM, AWWA and NSF requirements.
The leak was found near an underground tunnel, beneath a penstock
which channels rainwater out of the dam and toward the closest waterway, the Balog Creek.
Meandering through New Hampshire's White Mountains, a large wooden penstock
pipeline served as the main water supply for a local hydro facility, Jackman Station.
"Today we have successfully plugged our tailings pond's Tunnel A, and we are now focusing our resources on the making of a spillway to replace the penstock
system for draining water from the pond," Philex senior vice president for corporate affairs Michael Toledo said in a statement.
