Water level markers on flood-control systems to serve as warning sign
A recently completed flood-control system at Binatagan, Ligao City is painted with yellow, orange, and red markers to monitor the water level. The yellow paint that reaches up to 2 meters signifies that the water level is low and for up to 3.5 meters the area is considered safe.
On the other hand, when the water level reaches above the 3.5 meter-marker (orange), residents must evacuate the area for safety. The red marker signifies alert level on the area with the possibility of water to overflow in the flood-control system and that flooding may occur in the area.
