Utility company Maynilad has reduced its water production, citing increased sediment content levels of raw water from the Angat dam in Bulacan.
“Water production at Maynilad’s La Mesa Treatment Plants 1 and 2 has been reduced since yesterday [Saturdy] due to the high turbidity level of raw water…,” Maynilad said in its social media account.
Turbidity level refers to the amount of sediment contained in the dam’s water as soil erosion from the mountain side increased as a result of heavy rains from the enhanced southwest monsoon or “habagat.”
“Normal turbidity in Angat dam is at 300 nephelometric units (NTU). As of yesterday [Saturday], this level has increased to 1,600 NTU, forcing Maynilad to reduce the output of its La Mesa Treatment Plants 1 and 2 by 400 million liters per day (MLD) so it can remove the increased sediments from the raw water.”
Data show that Maynilad accounts for 850,000 households or 66 percent of the West Zone.
“We are continuously monitoring the raw water quality in Angat dam and conducting the necessary system adjustments so we can return to normal water production levels at the soonest possible time,” Water Supply Operations head Ronaldo Padua said in an advisory.
In an interview aired over radio dzBB, Grace Laxa, Maynilad spokeswoman, said they will return to their normal water production of 2,300 million liters per day when the turbidity levels in Angat dam are back to normal.
Meanwhile, the water utility company said it will be deploying 54 water tankers to the affected areas to deliver potable water.
Laxa said affected residents can request a water tanker by callin the Maynilad hotline.
