Constructed during the 19th-century agricultural expansion, Levada da Achada Grande (Levada Nova da Boaventura) was excavated to capture perennial mountain springs and transport fresh water across the steep volcanic slopes of São Vicente. Local stonemasons (cabouqueiros) worked suspended from hemp ropes against vertical basalt scarps, chiseling the channel bench by hand and laying fitted basalt masonry bonded with hydraulic lime mortar to maintain a gentle, continuous fall. Water distributors (levadeiros) historically patrolled this narrow service ledge to manage sluice gates (tornas) and apportion timed irrigation shares (giros de água) to local farmers cultivating sugarcane, bananas, and terraced vineyards.
