Water management

Water impoundment at Sanglay and Casay in Barangay Semirara remain as main sources of freshwater for both industrial and domestic use in 2015, but more sources of freshwater were developed and tapped in anticipation of the effects on the island of the El Niño phenomenon.  

Water for domestic use, especially water from Bunlao Spring in Bgy. Alegria, feeds into a PhP40 million filtration plant that was installed in June 2012. The use of reverse osmosis technology at the refilling station started in October 2015 which improved the quality of potable water available for island residents.
