The following day, November 11, 2020, Ulysses strengthened and was now classified into a typhoon; Signal No. 3 was raised in the western portion of Luzon, including Metro Manila. Packing heavy winds and rains, Ulysses was poised to bring destruction to the areas it will affect as soon as it made landfall.

On the morning of November 12, 2020, the heavy rains brought by Ulysses has already caused flooding in low-lying areas, including those within the East Zone Concession. The City of Marikina was heavily affected, by 7 A.M. the Marikina River water level reached 20.7 meters which prompted the nearest Manila Water facility, the Olandes Sewage Treatment Plant, to shut down. Similarly, flood levels in the Municipality of Cainta also caused one of the Company’s facilities in the area, the Brookside Pumping Station, to shut down. Also, due to the strong winds and flooding, power provider, Meralco, had to implement power outages to avoid electrocution in flooded areas.

As Typhoon Ulysses continued to move westward, Tropical Cyclone signals were downgraded, which prompted the Company to lower its alert level to Yellow in the evening. As a result of the onslaught of the typhoon, the Company experienced damages and disruptions to the operations of the East Zone Concession.

Securing the Safety of Employees

During the onslaught of Typhoon Ulysses, Manila Water ensured that all of its employees were accounted for, triggering a classification system that would identify the magnitude by which the typhoon affected their respective households. Through this, the Company identified that among its over one thousand employees, 445 were affected though on varying degrees.

Rescue operations were also implemented by the Company to those who were extremely affected or stranded due to the flooding. The Marikina North Sewage Treatment Plant was used as an evacuation center for heavily affected families of employees.

Disrupting East Zone Operations

Due to the flooding and power outages, most, if not all, water and wastewater facilities of Manila Water were affected, several of which were forced to shut down during the typhoon. Also, both Angat and La Mesa Dams breached their spilling levels, reaching over 214 meters and 80 meters, respectively.

Manila Water continuously assessed the conditions of all its water and wastewater facilities over the course and after the onslaught, regularly providing Management reports through the IMRT. The IMRT immediately decided on the courses of action necessary to ensure that immediate response was made. Overall, 5 water and 11 wastewater facilities had to shut down, as well as 31 facilities shifted to genset operations due to power outage. Ongoing projects were also affected by Typhoon Ulysses, damaging project sites across the East Zone Concession.

After the typhoon, Manila Water immediately assessed the status and extent of damage to all of its facilities. It’s noteworthy to report that all water facilities of the East Zone Concession were in good condition after the typhoon. Clean-up operations on all facilities was prioritized with all facility personnel working hand-in-hand to clear the mud and revert back to normal operations.
