Manila Water held the ceremonial commissioning of the Novaliches-Balara Aqueduct 4 (NBAQ4) in Quezon City. The new aqueduct, which will convey up to 1,000 million liters of water per day (MLD), will pave the way for the inspection, assessment, and subsequent rehabilitation of three other existing aqueducts, which have been operating since 1929, 1956, and 1968, respectively, to help ensure continuous water supply for more than 7 million customers in the East Zone.
