U radu se prati razvoj dubrovačkoga vodovoda tijekom XIX. i XX. stoljeća, čija je okosnica (sve do sredine XX. stoljeća) bio vodoopskrbni gravitacijski sustav izgrađen u XV. stoljeću. Na temelju dosadašnjih saznanja, arhivskih dokumenata, starih novinskih napisa te dokumentacije iz pismohrane današnje gradske tvrtke „Vodovod Dubrovnik” prate se rekonstrukcije i popravci dotrajaloga vodovodnoga kanala i popratnih objekata, izgradnja i održavanje gradskih fontana, provođenje vodoopskrbne infrastrukturne mreže prema privatnim objektima te u konačnici projekt izgradnje cjelovitoga suvremenoga vodoopskrbnog sustava polovinom XX. stoljeća, kojim se i danas vodom napaja gradsko područje.; Based on existing knowledge, archival documents, old newspaper articles, and documentation from the contemporary city company ‘Vodovod Dubrovnik’ (Dubrovnik Waterworks), this paper follows the development of the Dubrovnik waterworks during the 19th and 20th centuries. The backbone of the new waterworks until the mid-20th century was the gravity flow water distribution system built in the 15th century. This was an important project that signified a turning point in socio-economic progress and left a significant mark on the further development of Dubrovnik. Its communal value is also apparent from the fact that a water canal was built at that time and, with several extensions and modifications, continued to provide water to the city area until the mid-20th century, when construction of the contemporary Dubrovnik water supply system began. Due to financial difficulties, repair work was limited to the most critical issues, while the increasing demand for water was met by smaller-scale reconstructions of the aging water canal and reinforcing the existing gravity flow system. However, with the increase in the urban population in the late 19th century and the introduction of water into certain institutions and private objects, supplying water became increasingly problematic and the necessity of building a new, complete water supply system increasingly apparent. The first attempt to improve the water supply took place in 1897, when a contract was made with the owner of the mills at the spring of the river Ombla, the most abundant source of potable water in this area, to transmit a certain amount of water to the old water canal.
