Data from DeGolyer, Vol 66 pp. 262+. Works numbers were 54552, 54561 in February 1921 and 54564-54565 in March.
The sides of these wood-burning tanks were lettered "Inspectoria Federal de Obras Contra As Seccas [sic]", a Brazilian government agency tasked with bolstering the frequently dry northeast's ability to store and deliver water to its various communities and agricultural plantations and ranches.
