A first in Metro Manila, the NBAQ4 Project used a Tunnel-Boring Machine (TBM), which the team named, “Dalisay” which means pure in the English language.
WD News: East Zone concessionaire Manila Water recently inaugurated one of its flagship projects that seek to boost water security and service reliability for its more than 7.4 million customers in eastern Metro Manila and Rizal Province.
The P5.6-B Novaliches-Balara Aqueduct 4 or NBAQ4 project consists of laying a 7.3-kilometre, 3.1-diameter aqueduct via a tunnel boring machine, a first in an urban setting in the country. Other components of the project include constructing an intake facility at the La Mesa Reservoir, an outlet structure at the Balara Treatment Plant 2, and the downstream network system.
An aqueduct is a pipe, a tunnel, or any form of structure constructed to convey water from a source to a distant distribution point.
The risk of aging infrastructure and the rising demand for water supply about the continued increase in population continues to accentuate the critical need for another conveyance system to avert any impending disaster should any one of these aging aqueducts be compromised; hence, Manila Water embarked on the project of building a 4th aqueduct.
With the completion of the NBAQ4 last year, the sequential temporary service suspension of the 3 existing aqueducts for inspection, assessment, and subsequent rehabilitation may now be conducted. The NBAQ4 will also provide emergency redundancy in the event of a failure in any of the existing aqueducts.
“Part of our service obligation is safeguarding the quality of life of our 7.4 million customers, providing 24/7 water supply and making sure it will be sustained through projects like the NBAQ4,” says Jocot De Dios, President and CEO of Manila Water.
