Potworks Dam

Last updated

Potworks Dam is in central Antigua located close to Bethesda. One of the most significant water treatment facilities on the island is located on the southern shore at the Delapps Water Treatment Plant.

History

The dam has the name of a ceramics company. This area was a sugar cane farm owned by the Codrington family, one of the prominent planter families, constructed between the 18th and the 20th centuries. [1] The potters created clay berets to be exported with molasses- [1] the area touches Willoughby Bay to the southeast of St. John's Harbour and is part of the island's heavy clay soil zone.

In order to stop recurrent water emergencies, the storage facility was constructed in the late 1960s. A 19th-century bridge across Ayers Creek and portions of the manufacturing buildings were covered by the dam when it was constructed. [1] A sudden exceptional downpour occurred just prior to the barrier's completion in 1968, preventing the seabed from being ready. [2] The building could open in May 1970; this is marked by a memorial plaque. [1]

The dam showed its worth in 1974, when there was a severe drought that lasted from January to mid-August. But in the midst of the disastrous 21-month drought that occurred in 1983–1985, the lake finally dried up in late 1984. This led to the total collapse of the water supply, necessitating the transportation of drinking water from nearby islands. This ought to stop now that seawater desalination has taken place. [1]

Functions

Potworks Reservoir

The lake is approximately 2½ kilometers long, 130 hectares in size, and can hold approximately 4 million m³ of water. It is the Caribbean's largest reservoir as a result. [3] It supplies the island's drinking water supply, which is affected by drought, in contrast to other Caribbean islands. [4] About 7 million m³, or 2/3 of the island's entire water storage capacity, is contained in the Potworks reservoir. [5] [6] [7] The watershed area is 2,430 hectares, or 24 square km. [5] [6]

Other than the reservoir, the island gets its water from several tiny cisterns and household fountains, as well as from saltwater desalination plants such Semibcorp Antigua, Camp Blizzard, and Ffryes Beach. [8]

Delapps Water Treatment Plant

The Delapps Water Treatment Plant, located south of the lake and across from Bethesda, receives the water supply. It undergoes reversosmotically treated there before being put into the island's water network. With the half-powerful Bendals Water Treatment Plant (Dunnings Dam) and a few smaller plants, the surface water treatment plants account for 1/3 of the island's current daily requirement. The plant produces 7,000 m³ per day, or around 20% of the total. [8]

Water also flows via Delapps to the smaller Collins Reservoir below Ayers Creek and, if needed, to the agriculturally-oriented Bethesda Dam south of Willoughby Bay. [9]

Water supply and sanitation in Hong Kong is characterized by water import, reservoirs, and treatment infrastructure. Though multiple measures were made throughout its history, providing an adequate water supply for Hong Kong has met with numerous challenges because the region has few natural lakes and rivers, inadequate groundwater sources, a high population density, and extreme seasonable variations in rainfall. Thus nearly 80 percent of water demand is met by importing water from mainland China, based on a longstanding contract. In addition, freshwater demand is curtailed by the use of seawater for toilet flushing, using a separate distribution system. Hong Kong also uses reservoirs and water treatment plants to maintain its source of clean water.

Water supply and sanitation in Singapore are intricately linked to the historical development of Singapore. It is characterised by a number of outstanding achievements in a challenging environment with geographical limitations. Access to water in Singapore is universal, affordable, efficient and of high quality.

The Thames Gateway Water Treatment Works or Beckton Desalination Plant is a desalination plant in Beckton, London, adjacent to Beckton Sewage Treatment Works. The plant takes brackish water from the River Thames and converts it into drinkable water through a reverse osmosis process. The first of its kind in the UK, it was built for Thames Water by a consortium of Interserve, Atkins Water and Acciona Agua. It was opened by Prince Philip, Duke of Edinburgh, on 2 June 2010. It was planned to provide up to 150 million litres of drinking water each day – enough for 900,000 Londoners. – but by 2023 had only operated on three occasions, and at two-thirds of its planned capacity.

The Victorian Desalination Plant is a water desalination plant in Dalyston, on the Bass Coast in southern Victoria, Australia. The project was announced by Premier Steve Bracks in June 2007, at the height of the millennium drought when Melbourne's water storage levels dropped to 28.4%, a drop of more than 20% from the previous year. Increased winter-spring rains after mid-2007 took water storage levels above 40%, but it was not until 2011 that storages returned to pre-2006 levels.

The Sydney Desalination Plant also known as the Kurnell Desalination Plant is a potable drinking water desalination plant that forms part of the water supply system of Greater Metropolitan Sydney.

The SEQ Water Grid is a region-wide, long term, water supply scheme that provides a sustainable water infrastructure network for the South East region of Queensland, Australia. The project was the largest urban response to the drought in Australia, which severely affected water supplies in Brisbane and surrounds, particularly between 2004 and 2007. The basic component of the project was a 535-kilometre (332 mi) network of potable bulk water pipelines that connect areas that have an oversupply of water to those areas lacking water. The project went online in October 2008 and by November 2008 parts of the region were receiving a diversified supply of water for the first time.

<span class="mw-page-title-main">Seawater desalination in Australia</span>

Australia is the driest habitable continent on Earth and its installed desalination capacity has been increasing. Until a few decades ago, Australia met its demands for water by drawing freshwater from dams and water catchments. As a result of the water supply crisis during the severe 1997–2009 drought, state governments began building desalination plants that purify seawater using reverse osmosis technology. Approximately one percent of the world's drinkable water originates from desalination plants.

<span class="mw-page-title-main">Water supply and sanitation in Namibia</span>

Namibia is an arid country that is regularly afflicted by droughts. Large rivers flow only along its northern and southern borders, but they are far from the population centers. They are also far from the country's mines, which are large water users. In order to confront this challenge, the country has built dams to capture the flow from ephemeral rivers, constructed pipelines to transport water over large distances, pioneered potable water reuse in its capital Windhoek located in the central part of Namibia, and built Sub-Saharan Africa's first large seawater desalination plant to supply a uranium mine and the city of Swakopmund with water. A large scheme to bring water from the Okavango River in the North to Windhoek, the Eastern National Water Carrier, was only partially completed during the 1980s.
