MMDA plans rainwater harvesting system on flyovers, MRT posts

The Metropolitan Manila Development Authority (MMDA) plans to collect rainwater from flyovers and Metro Rail Transit (MRT) elevated structures to conserve water resources ahead of a potentially prolonged El Niño dry spell, agency officials said Monday.

Atty. Victor Nuñez, director of the MMDA's Traffic Discipline Office, said the agency is designing catchment systems to hook directly onto downspouts on flyovers and MRT support columns.

The authority also plans to distribute rainwater collection barrels to schools and government facilities across the capital.

"One of the plans is to put rainwater catchments on the downspouts of flyovers and MRT posts," Nuñez said.

Collected rainwater will be used to maintain urban foliage and clean public areas, helping offset demand for treated municipal water.

To protect field personnel from rising temperatures, Nuñez said the MMDA will adjust working conditions for its traffic enforcers beginning in January. Modifications include rolling out lightweight short-sleeved uniforms and introducing mandatory 30-minute hydration breaks.

Nuñez cited that hydration breaks will be staggered among personnel to ensure continuous coverage at key intersections.

"Not everyone will take a break at the same time," Nuñez explained. "When officers share a post, half will take 30 minutes so that fixed posts remain manned."

The agency is also coordinating with private firms to urge heat and hydration precautions for outdoor workers.
