NPC: Pulangi IV Maramag in good condition; flashflood situation: “manageable”

VALENCIA CITY (Bukidnon News/ 28 December) – The National Power Corporation’s Pulangi IV Hydroelectric power plant and dam located near Maramag is in good condition, with no cracks even with the flashfloods Tuesday morning owing to the overflow of rainwater from upstream, plant manager Rudy Brioso told MindaNews Wednesday.
Brioso said he led a team who inspected the power plant and the reservoir Tuesday and found the power complex in “good condition,” and has “no
cause for worry.” He said the flashfloods in the power complex is “manageable” even if he warned residents in
the riverbanks downstream to keep off the river.
But he said they have to open two out of the complex’s seven spill gates early morning to anticipate the flash floods even if he said it
is a standard procedure to avert damage to the power complex structure.
He said that by 4am the water level at the reservoir was at 284.35 meters, which is barely one meter less than the maximum 285.5m water level. They opened the two spill gates by 5am and 6am respectively, about the time residents in Purok 5 and other villages along the Pulangi River banks noticed that water started to creep to their houses. He said when they saw the water level kept rising by 10am they decided to open the third gate. He said they did “gradual” release of water and maintained the level at 285.2, or about 0.3 meters elevation allowance to the maximum level.
He said it is a buffer just in case more flashfloods will come brought by continues rains upstream.
He belied reports of the alleged collapse of the dam further saying the release of water is under control. The 255-megawatt Pulangi IV
hydroelectric power plant in Maramag, Bukidnon resumed was temporarily
shut down in April this year for repairs during the Holy Week.
The National Power Corporation announced on April 20 the maintenance
and repair of three units of the power facility for cracks and leaks.
It announced that maintenance work would be done by April 23, ahead of
the resumption of operations on April 25. Engr. Jimmy Apostol, Bukidnon
irrigation manager of the National Irrigation Administration, admitted
that it was their water siphon facility, which diverts water from the
Pulangi River to irrigation canals that was destroyed.  He estimated
about P50 million worth of irrigation structures damaged, including
the Lateral C canal and two spur dikes in Brgy. San Isidro.
He clarified that their Lumbayao diversion dam, which channels water
from the Pulangi to another irrigation district upstream of the
Pulangi did not gave way or collapse as earlier reported.
He said it is stable and is functional. (Walter I. Balane)
