MANILA — With the coming rainy season and expected inclement weather that could lead to heavy rains and storms, the Metropolitan Manila Development Authority (MMDA) is rushing repairs to the damaged Navigational Gate which has caused flooding in low-lying areas in the Navotas and Malabon areas.

Since the Navigational Gate’s downtime in March, most of the barangays located in low-lying areas of the aforementioned cities were greatly affected and experienced severe flooding during high tides in their vicinities.

According to MMDA Flood Control and Sewerage Management Office (MMDA-FCSM) chief Engr. Baltazar Melgar, they have decided to temporarily stop the operations of the Navigational Gate located at the mouth of the Tangos River in Navotas City to give way to its immediate repair.

“The Gate needs to undergo emergency repair since we have already encountered problems last March. The structure is already more than a decade old since its completion in 2008 and some of its mechanical and electrical components have deteriorated and would continue to deteriorate if not repaired,” Melgar pointed out.

Repair work on the Navigational Gate will include the re-alignment of the link arm and replacement of damaged parts.

“We have to admit that (our) private contractors are having difficulty since repairs are conducted underwater. Also, the silt and damage accumulated on the gate and chamber were severe, thus, mud blasting and de-silting activities have to be conducted to lessen the weight of the gate leaf and prevent the gate’s trunnions from further misalignment,” the MMDA-FCSM head noted.

Meanwhile, MMDA chairman Atty. Romando Artes cited how the floodgates have been affected by the waves of boats passing through the Dampalit River.

“Private contractors have been conducting the repairs of the Navigational Gate for four weeks now. We are giving them 10 days to complete the repairs so that the flooding in the communities would subside,” Artes disclosed. (AI/MTVN)
