the system was constructed a century afterwards, through the exhaustive research of the spanish franciscan friar felix huerta, who was serving as administrator of the san lazaro hospital in manila, using his long-forgotten funds, which huerta tracked down after going through over 300 documents. under his urging, the carriedo fountain was built in may 1882 as part of the carriedo water works system and was inaugurated by governor-general fernando primo de rivera on july 24, 1882. it was named after the man who had conceived of and eventually funded the system, francisco carriedo y peredo (1690–1743).
