The department also instructed provincial offices to check roads along reservoirs and irrigation canals over fears they could subside due to the drop in water levels.
The RRD announced on its website that provincial and district offices will cooperate with provincial administrations nationwide in deploying water trucks to supply villagers in drought areas.
It also instructed RRD officials to check all rural roads along reservoirs and irrigation canals for cracks and other signs of subsidence caused by dropping water levels.
Signs to warn motorists will be erected along roads found to be at risk of subsidence.
The department also ordered offices to be on standby to repair roads immediately if they are hit by subsidence. Roads repaired after subsidence must be checked regularly for further damage due to drought, it added.
