The WEB Aruba NV (Water- en Energiebedrijf Aruba NV) is a power company in Oranjestad (Aruba) .
history
WEB was founded as an independent company in January 1992 by amalgamating former sole proprietorships and has been responsible for the island's electricity and water supply on behalf of the government. Together with the subsidiary NV Elmar, WEB operates the power plant blocks, seawater desalination plants and the entire supply network for electricity and water to the end consumer.
A central point here is the water supply for the island's residents, as Aruba gets 100 percent of its drinking water from seawater desalination.

water
WEB Aruba NV prepares around 2,000 tons of drinking water per day. Since 1932, seawater desalination has been carried out using a thermal process, whereby the supplied seawater is heated with the waste heat from the caloric power plants and the drinking water is obtained in a multi-stage expansion evaporation system. A reverse osmosis system has also been in operation since 2008 , which uses around 75% less energy than conventional thermal evaporation systems and thus helps to reduce fuel consumption.
WEB opted for ultraviolet (UV) disinfection technology, no chlorine is used in the preparation of drinking water. After the desalination process, the water is treated by seven UV systems before it is transported to the large storage tanks at elevated locations on the island. There are six water reservoirs with a total capacity of 72,600 cubic meters distributed over the island, which supply the entire pipeline network with eight decentralized pump stations.

Wastewater treatment
On Aruba, wastewater is currently being treated by two wastewater treatment plants (ARA), one in Parkietenbos on the west coast and the other in Zeewijk on the east side of the island. The sewage treatment plant in Parkietenbos processes sewage from septic tanks, which is delivered by truck from all over the island, while the Zeewijk sewage treatment plant processes sewage from the urban area of San Nicolas, the second largest city in Aruba, which has a sewer system.
Both wastewater treatment plants use UV as the final treatment step for disinfection after the water has gone through various filtering and treatment steps including grease removal. The biological treatment and the tertiary disc filtration ensure that some of the treated wastewater can be reused to irrigate the two golf courses and other green areas on the island. The Parkietenbos sewage treatment plant treats up to 75 m³ per hour, while the Zeewijk plant can process up to 200 m³ per hour.
electricity
In 2014, around 20 percent of the electricity required was generated from wind and solar power, the remaining 80 percent is generated by steam power plants that are fueled with heavy fuel oil. The fuel for this is imported.
Installed power plant units
- 2 × Babcock & Wilcox , installed in 1958, renovated in 1994
- 3 × Babcock & Wilcox, installed in 1963/1964, renovated in 1995/1996
- 1 × Babcock & Wilcox, installed in 1996
- 1 × Babcock & Wilcox, installed in 2002
The seven boiler systems generate a total of 860 tons of steam per hour; the connected turbines produce around 102 megawatts of electricity per unit. When there is peak demand, the generators can each generate 125 megawatts. The waste heat from the power plants is used for seawater desalination.

Wind farm
Since 2009, the company has been operating a wind farm with ten wind turbines and a total output of 30 megawatts on the east coast of the island near the airport in San Nicolas-Noord . The wind farm was built by a company from Austria; the Vesta V90 / 3000 wind turbines were built by the Danish manufacturer Vestas Wind Systems . 12 ° 28 ′ 26 " N , 69 ° 53 ′ 29" W.
