Knights period
Water PROVISION IN BIRGU DURING THE ADMINISTRATION OF THE KNIGHTS OF ST. JOHN
“….. the Knights of St. John took possession of the Islands in October 1530, fixing their residence at the Borgo (now called Vittoriosa), a small town behind the Fort of S. Angelo.
The springs nearest to the Borgo where those of the Marsa, so that for its water supply the town depended mainly on tanks cut out under the houses and in the public streets. The Marsa springs were very important at the time, as they were used extensively by the ships in the harbour and by the galleys of the Order.”
Sir T. Zammit, The Water Supply of the Maltese Islands, 1931
“During the Siege, the people of the Borgo were in great distress due to the want of an adequate supply of water. The Grand Master caused the Commander Geofre de Loaysa and Jacopo Colorati, who were in charge of the water supply to make enquiries as to the possible increase of the water in the besieged city, and on the 21st of July 1565, a tank was discovered under the house of a certain Doctor Cadamosto and found to be connected with a spring of running water which, though was brackish, was fully utilized by the public during the Siege.”
Sir T. Zammit, The Water Supply of the Maltese Islands, 1931

The rainwater harvesting capacity of cisterns was therefore of extreme importance for the harbour area, and in particular the three cities. It is definitely not surprising to find that in late 1722, Grand Master António Manoel de Vilhena ordered the engineer Romano Fortunato Carapecchia to carry out a detailed inventory of all the cisterns and wells that existed at the time in Valletta, Vittoriosa, Senglea and Cospicua. The results of this survey are found in Romano Carapecchia’s 1723 “Ristretto generale di tutte le Cisterne e Gebbie publiche e private con l’acque ritrovate nelle medesime, tanto in questa Citta’ Valletta, come nelle Citta’ di Vittoriosa, Senglea e Bormola.”
