The gardens of the rotonda is a terraced garden, situated close to the historical centre of Padua, behind the sixteenth century wall and the Rampart of the Cat.
The name is connected to an episode which occurred during the 1509 siege by the German King Maximilian I during the War of the League of Cambrai. According to legend, a cat was flayed alive to frighten the enemy with its screams. A sculpture of a cat jutting out of a niche was placed on the outer part of the tower facing Codalunga Street in order to commemorate this event, as well as symbolize the freedom of the people of Padua.
The garden is so called because it was planned around the area where a monumental suspended tank with a circular shaped base was built. It is the first water tank to be built in Padua, a prestigious work of engineering dating back to the 1920s. It can hold 200 cubic metres (44,000 gallons) of water and was considered not only the best aqueduct in Italy but also one of the best water tanks in Europe.
It is also remarkable as regards the construction materials since it is one of the earliest examples of the use of concrete in Padua. The decision to build the water tank and Codalunga water power plant just on this spot was due to the following events:
The space between the water reservoir and the wall was used for a public garden, inaugurated in 1925 and named della Rotonda. To enter the garden one cross a stepped path starting from Vicolo Mazzini and continuing parallel to Viale della Rotonda. The path is characterized by five balconies with a circular fountain in the centre and each balcony is framed by a simple ring of grass. The presence of many fountains is due to the presence of the water reservoir. In every fountain there are many water-lilies which fill the visitors with a sense of pleasure and serenity.
Every terrace is separated from the next by gardens and gravel paths shaped like a circular geometric garden with an axis perpendicular to the water reservoir. The style of the Rotonda Garden is a mixture of Liberty and Classicism but it also presents features of the 20th century. The architectural style recalls the late baroque, but it is also rich in classical references, for example the flower urns and the tower mausoleum are carried out with a secessionist taste, while the shape of the flower beds, (round elliptic and drop-like), are typically liberty. In the flower beds are low bushes that are reminiscent of palms and agaves. At first the garden was apparently meant to hold few shrubby plants to be exposed to the light so as to put the main elements in contact with the water of the garden. At present the garden is being neglected and the trees that live here have no intrinsic value. These trees represent a serious problem for the masonry banks because their roots push on them. The main entrance is characterized by an imposing wrought-iron railing in liberty style. The garden has and overturned- L-shape which proceeds long and narrow in the balcony and terraces and widens at the end of these, where the water reservoir is situated. On it there are geometric elements in the lower part, floral decorations in the central park and Padua coat of arms in the upper part.
At the bottom of the garden there is the stately water reservoir; its main fountain, which has a temple form, is close to a strong terraced wall structure. Inside there are some circular pilasters connected to each other by means of perimeterl and radial concrete arches, disposed on two overlapping floors because they have to support the suspended water reservoir properly.
The story of the aqueduct started on 26 August 1875, when the Mayor said
“water is so vital to man and society, like air and light, that an abundance of water distribution and a regular distribution to the whole city, deserve to be fully kept alive in the citizens’ memories”.
Following study, water from the Brenta and Bacchiglione rivers was excluded owing to their torpidity and bacterial counts, instead water of Dueville source was chosen. On 17 February 1886, the Padua town hall granted the management of the new aqueduct to Società Veneta per Imprese and Costruzioni Pubbliche. On 13 1888 in Unità d’ Italia Square, the much expected event took place: in front of an exulting crowd of Paduans the first pure water flow was raised. The water transport from Dueville was carried out by means of an underground supply 42 km (26 mi) long made of concrete and bricks, thoroughly plastered in order to ensure the complete isolation from external agents; this supply is still working. The reservoir, however, did not slacken the use of wells by Paduans, who avoided the costly aqueduct water. This bankrupted the Società Veneta administration. Accordingly, the commune, in 1892, decided to manage the service on its own through a special town hall authority.
This office ceased its activity in 1904 when the town hall administration decided to combine the water and the gas service. Two Municipal Companies were set up and these merged into one in 1984, when the AMAG or Azienda Municipalizzata Acqua-Gas of Padua was established.
Construction of the "Rotonda" building, located at the corner of Via Citolo da Perugina, was begun on 21 September 1923. It was planned for dual functions: first as an elevated water tank and second, as to house in its base a chapel commemorating certain refugees killed in the recent world war. Its round shape resembles the Ancient Roman Tomb of Caecilia Metella in Rome.
The aqueduct monumental reservoir is 36 meters (118 feet) high; at the base, a small chapel was in memory of refugees from Padua, looking for shelter in the nearby courtyard of the Burlini family's house, and who died during an Austrian aerial bombardment during the war. Around the base is an inscription recalling the event:
“ SANGUINEM OLIM ATROCITER EFFUSUM AQUA PIE DEFLUENS LAVET MOLES IN CAELUM PROFERAT PERPETUO”.
On the reservoir, there is also the tombstone of Mr Andrea Moschetti, with the following inscription:
“Il martirio di 93 innocenti (....) salga a Dio olocausto perenne di futura grandezza alla patria di un nuovo patto d’amore tra i popoli”, it can be translated as: “May the torture of 93 innocent persons reach God as eternal holocaust and a new pact of love among the peoples.”
The reservoir aimed mainly to increase the daytime water availability by collecting it during the night. While its external shape recalls an ancient Roman mausoleum, the inside was technically innovating for its days. The essential lines that show the main structures, are so modern that it seems as if they are drawing the route of the water while falling down to the ground floor and into the earth.
According to the increasing need of water during the time period up to Second World War, water had been taken from the water-layer of the town of Dueville.
After the war, this system was not efficient enough anymore, and the lack of water became a serious problem. Consequently, studies and projects to sort out this matter became more intensive, and from the year 1955 the Town Hall Council of Padua decreed to devise the construction of the “New Aqueduct”.
The most important action was building a second water-supplier called the “900 metres Conveyance”; whose construction was ended in 1961.
In the meantime, in order to cope with water emergency situations an auxiliary aqueduct was also built; it consisted in a system for purifying the superficial water of the river Brentella, which partially overcame the shortage of water complained by the citizens. Afterwards relevant actions were taken in order to improve the efficiency and the functionality of the whole water system in Padua. Among the many actions taken, we can mention the following most important ones:
Padua aqueduct contributed to solve the problems related to water supply of some smaller distribution authorities. The following are the most significant data concerning the aqueduct management:
The water arrives to the receiving system after undergoing a long natural conditioning process in the deeper layers. The most varied rock fragments melt and shed their salts into the water, mineralising it. Therefore, Padua waters are classified as “medium-mineral” waters. The AMAG company has been dealing with the disinfection treatment of the waters introduced into the pipes since its start.
Despite concerns in the 21st century about water quality; however the water is tested and drinkable according to legal standards, so much so that the administration is currently planning to build some cleaning up systems to keep the water within optimum quality standards.
A fountain is a piece of architecture which pours water into a basin or jets it into the air to supply drinking water and/or for a decorative or dramatic effect.
The Massachusetts Water Resources Authority (MWRA) is a public authority in the Commonwealth of Massachusetts that provides wholesale drinking water and sewage services to certain municipalities and industrial users in the state, primarily in the Boston area.
The Delaware Aqueduct is an aqueduct in the New York City water supply system. It takes water from the Rondout, Cannonsville, Neversink, and Pepacton reservoirs on the west bank of the Hudson River through the Chelsea Pump Station, then into the West Branch, Kensico, and Hillview reservoirs on the east bank, ending in at Hillview in Yonkers, New York.
Mt Evelyn Aqueduct was a former feature of the Melbourne water supply infrastructure that was built by the Melbourne and Metropolitan Board of Works The O'Shannassy Water Supply. Where the aqueduct crossed the lower lying areas around Wandin and approaching Mount Evelyn, it was in steel or wood-stave piping, converting to open concrete-lined channel when the higher levels were reached. It went through the township of Mount Evelyn in open channel winding around the local contours to just above what is now Johns Crescent, then part of the 'Pine Mont Estate.'
A combination of aqueducts, reservoirs, and tunnels supply fresh water to New York City. With three major water systems stretching up to 125 miles (201 km) away from the city, its water supply system is one of the most extensive municipal water systems in the world.
The Aqua Virgo was one of the eleven Roman aqueducts that supplied the city of ancient Rome. The aqueduct fell into disuse with the fall of the Western Roman Empire, but was fully restored nearly a millennium later during the Italian Renaissance to take its current form as the Acqua Vergine. The Aqua Virgo was completed in 19 BC by Marcus Agrippa, during the reign of the emperor Augustus. Its source is just before the 8th milestone north of the Via Collatina, in a marshy area about 3 km from the Via Praenestina. It was also supplemented by several feeder channels along its course. The name is thought to be derived from the purity and clarity of the water because it does not chalk significantly. According to a legend repeated by Frontinus, thirsty Roman soldiers asked a young girl for water who directed them to the springs that later supplied the aqueduct; Aqua Virgo was named after her.
The Romans constructed aqueducts throughout their Republic and later Empire, to bring water from outside sources into cities and towns. Aqueduct water supplied public baths, latrines, fountains, and private households; it also supported mining operations, milling, farms, and gardens.
The Bog Brook Reservoir is a 379-acre (153 ha) reservoir in the Croton Watershed in southern New York State, part of the New York City water supply system. It is located in the town of Southeast in Putnam County, approximately 38 miles (61 km) north of New York City. It was formed by the damming of Bog Brook, a small tributary of the East Branch of the Croton River. The reservoir was put into service in 1892, making it one of the older in the system.
The Diverting Reservoir is a reservoir in the New York City water supply system in the town of Southeast, New York, in Putnam County immediately south of the village of Brewster, New York. Part of the system's Croton Watershed, it lies about 50 miles (80 km) north of New York City. Construction impounding the East Branch Croton River began early in the 20th century and was completed by 1911.
The Staines Reservoirs are two large pumped storage reservoirs that lie to the east of the King George VI Reservoir near Heathrow airport in the county of Surrey and within the Colne Valley regional park. The village of Stanwell is to the north east, and the town of Staines is to the south. The two reservoirs are situated between the A3044 and the A30. They were completed in 1902.
Joseph Monier was a French gardener and one of the principal inventors of reinforced concrete.
De aquaeductu is a two-book official report given to the emperor Nerva or Trajan on the state of the aqueducts of Rome, and was written by Julius Sextus Frontinus at the end of the 1st century AD. It is also known as De Aquis or De Aqueductibus Urbis Romae. It is the earliest official report of an investigation made by a distinguished citizen on Roman engineering works to have survived. Frontinus had been appointed Water Commissioner by the emperor Nerva in AD 96.
The Weston Aqueduct is an aqueduct operated by the Massachusetts Water Resources Authority (MWRA). Now part of the MWRA backup systems, it was designed to deliver water from the Sudbury Reservoir in Framingham to the Weston Reservoir in Weston. The 13.5-mile (21.7 km) aqueduct begins at the Sudbury Dam, and passes through the towns of Southborough, Framingham, Wayland, and Weston. In 1990, the route, buildings and bridges of the aqueduct were added to the National Register of Historic Places as the Weston Aqueduct Linear District.
The Sudbury Aqueduct is an aqueduct in Massachusetts. It runs for 16 miles (26 km) from Farm Pond at Waverly Street in Framingham to Chestnut Hill Reservoir in Boston’s Chestnut Hill neighborhood. A later built extension main runs from the Farm Pond gatehouse to the gatehouse at the Stearns Reservoir where additional mains connect to the Brackett and Foss Reservoirs Going east from Framingham, it runs through Sherborn before entering Natick. From Natick it runs east through Wellesley and Needham to the Charles River, which it crosses on the Echo Bridge into Newton. It ends at the Chestnut Hill Reservoir on the Newton side of the Newton-Boston line. The Massachusetts Water Resources Authority (MWRA) operates the aqueduct.
The Mokelumne Aqueduct is a 95-mile (153 km) water conveyance system in central California, United States. The aqueduct is supplied by the Mokelumne River and provides water to 35 municipalities in the East Bay in the San Francisco Bay Area. The aqueduct and the associated dams, pipelines, treatment plants and hydroelectric system are owned and operated by the East Bay Municipal Utility District (EBMUD) and provide over 90 percent of the water used by the agency.
Nahr water system provided clean water for the people of Aurangabad and its suburbs. It was created by Malik Ambar who founded the town under the name Khadki and was later expanded by Aurangzeb in order to facilitate the military activity that became prevalent under Mughal rule during the 17th century.
An aqueduct is a watercourse constructed to carry water from a source to a distribution point far away. In modern engineering, the term aqueduct is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose. The term aqueduct also often refers specifically to a bridge carrying an artificial watercourse. Aqueducts were used in ancient Greece, ancient Egypt, and ancient Rome. In modern times, the largest aqueducts of all have been built in the United States to supply large cities. The simplest aqueducts are small ditches cut into the earth. Much larger channels may be used in modern aqueducts. Aqueducts sometimes run for some or all of their path through tunnels constructed underground. Modern aqueducts may also use pipelines. Historically, agricultural societies have constructed aqueducts to irrigate crops and supply large cities with drinking water.
The Greater Winnipeg Water District Aqueduct supplies the city of Winnipeg, Manitoba with water from Shoal Lake in the Kenora District of Ontario. It was put in service in 1919 and cost nearly CDN $16 million. It has a capacity of 85 million Imperial gallons per day and extends approximately 96 miles (154 km) from an intake structures on Shoal Lake to the Deacon Reservoir on the east side of the city. Water flows by gravity from the lake, since the aqueduct drops about 300 feet (91 m) over its length. The Greater Winnipeg Water District Railway was built for construction and maintenance of the aqueduct. The capacity was planned for a city of one million inhabitants; peak water usage by the city was in 1988 and the capacity of the aqueduct has never been entirely used. An additional 12 miles (19 km) branch was completed in 1960.
Paddington Water Tower is a heritage-listed water tower at 16 Garfield Drive, Paddington, City of Brisbane, Queensland, Australia. It was designed by Metropolitan Water Supply & Sewerage Board and built by day labour in 1927. It was added to the Queensland Heritage Register on 23 June 2000.
The Upper Canal System, also called the Southern Railway Aqueduct and the Cataract Tunnel, is a heritage-listed operational gravity-fed aqueduct that supplies some of the potable water for Sydney, in New South Wales, Australia. The aqueduct comprises 54 kilometres (34 mi) of open canals, tunnels, and closed pipelines that connect the Upper Nepean Scheme with the Prospect Reservoir. The aqueduct is managed by the Sydney Catchment Authority on behalf of WaterNSW, an agency of the Government of New South Wales. It was listed on the New South Wales State Heritage Register on 18 November 1999.
