Several areas of the West Zone being serviced by Maynilad Water Services Inc. (Maynilad) will experience service interruptions for 12 to 41 hours next week.
Maynilad said the water supply to 10 cities and two towns in Cavite province will be cut because workers will realign a seven-foot-tall primary line along Juan Luna St. corner Hermosa St. in Tondo, Manila.
The interruption will also give way to the flood control project of the Department of Public Works and Highways (DPWH).
Among the areas that will be affected are portions of Caloocan, Manila, Pasay, Makati, Parañaque, Muntinlupa, Las Piñas, Cavite City, Bacoor City, Imus City, and the towns of Kawit, Rosario at Noveleta in Cavite.
The rotating water service interruptions will start at 1 p.m. on August 10 (Monday) until 10 p.m. on August 13 (Thursday), and from 1 p.m. on August 17 (Monday) to 3 p.m. on August 18 (Tuesday).
Maynilad urged its customers to store enough water for the duration of the service interruption.
Those with existing overhead tanks were advised to clean them first before storing water.
Maynilad will take about 107 hours to stop water flow through the seven-foot-tall (2,200mm diameter) primary line, insert line stoppers to isolate the segment that will be removed, cut the pipe segment, and allow water to flow through a bypass pipeline while the new cross-under primary line is installed.
“The company is implementing a three-day gap between its scheduled water supply interruptions (August 10–13 and August 17–18) so its customers can replenish their stock of water before the project is resumed,” the water firm said.
Maynilad is realigning its water pipe because it is in the path of the interceptor drainage line of the DPWH, which will be laid along Blumentritt St.
The interceptor project is expected to be finished in March next year, according to Reynaldo Tagudando, director of the DPWH-National Capital Region.
The P500-million interceptor project will direct floodwaters from the northern part of Metro Manila to Manila Bay.
Tagudando said only 480 meters of the 3.3-kilometer interceptor was left unfinished.
