A homeowner in the Bahamas faced challenges with his public water supply due to poor water quality and low water pressure on the property, resulting in not enough pressure in the faucets. For that reason, the owner developed an interest in desalination options.
Through a local installer, he learned about and was recommended AqSep desalination solutions. Subsequently, a WM9000E desalination unit was installed in 2011, which has had significant implications for his water supply.
After installing the WM9000E desalination unit, which produces 9,000 liters/2,300 gallons of fresh water per day, the water supply has been running perfectly. The homeowner expresses great satisfaction with the implementation of the product and the local service. Service has been conducted continuously by a local AqSep partner over the years.
The homeowner says: “It has made a major difference in the daily life of my family. We have perfect water for showering, washing clothes without discoloring and other daily needs. But most important, we can drink the water from the tap, and we can make our perfect Italian espressos. Every day!”
The AqSep turnkey solution has reduced his water costs and supplied him with his own independent and durable water supply of high quality. This enables him to have pure water for all his household purposes. The purchase of the desalination unit has thus been highly valuable to him.
The private estate is situated at Jumby Bay; a private island off the coast of Antigua. The island has no natural water supply, and the private homes therefore depend on the island’s central water supply for fresh water and electricity.
AqSep found the perfect solution for the customer and his needs. For a private estate of this size covering 18,000 ft² (1,672 m²) with an 82’ (25 m) pool and multiple acres of land, a single watermaker is not enough to supply the estate with the required amount of water. For that reason, four WM11000E desalination units were installed at the private estate. With this desalination system, the owner can self-sufficiently meet the demand for drinking water.
As the desalination units obtain power from the estate’s own solar power plant, they predominantly run during the hours where the sun reaches its highest point. The units then reap excess energy and harness this to produce fresh water. If required, power can also be taken from the solar cell system’s battery storage. Each WM11000E unit can run individually or in parallel depending on available power and water demands.

The private luxury estate is situated on a large private cay beach lot with extensive new landscaping which requires large volumes of continuous irrigation. With a daily consumption of 5,000-10,000 gallons, the island’s “city water” costs would be very high. Moreover, the private cay constitutes a challenging location as the island can only be reached by private plane or private sea plane and boat transfer from a neighbouring island with a runway.
Thanks to AqSep desalination technology, the customer is now supplied with an independent and cost-efficient water supply that consists of a dual system of a WM11000E and WM22000E desalination unit. Running two desalination units in parallel provides the added benefit of system redundancy. City water is therefore only considered as an emergency backup.
The turnkey installation features a submerged Grundfos pump intended for seawater operation, and both desalination units are equipped with a Danfoss variable speed drive that helps to protect against power quality fluctuations. The units are installed on rack in a pump house in the private estate, and both of them allow for remote monitoring and control.
One of the first activities in the construction process was to establish an AqSep water supply as a temporary setup in order to produce water during the construction period. This is what appears from the photo.
The AqSep solution has not only reduced the customer’s water costs and supplied him with his own independent and durable water supply of high quality, it has also made the customer’s dream of having extensive landscaping on a tropical island possible.
