Water Authority - Cayman

The Water Authority provides pure, wholesome and affordable water to Grand Cayman and Cayman Brac.

The Authority supplies piped water, trucked water, sewerage and septage services to their various service areas throughout the Cayman Islands.

Water is extracted from deep underground via a series of abstraction wells. The water that is extracted is saline groundwater that has to be treated using Reverse Osmosis. This process, with the addition of three fluoride-free chemicals, makes the water safe to drink straight from the tap. All chemicals added to the water are National Sanitary Foundation approved for potable water use.

The first 12 cubic meters (m³) (approximately 3,200 US gallons) is charged at CI$4.34/m³. Anything above that costs CI$5.57/m³. In addition, there is also a statutory fee of $0.22/m³, and an energy adjustment factor charge (that varies monthly and covers the fluctuations in the cost of electricity to produce the desalinated water). Monthly meter charges also vary depending on the size of the meter, from CI$5 to CI$58 for meter sizes ranging from 20mm to 150mm.

The Authority’s website allows property owners to register for an online account. While the Authority offers a variety of payment methods, anyone can pay their bill online at the Authority’s website regardless of whether they have an online account or not. It also provides information on outages, tips on saving water, water and sewage application forms, meter reading request forms and online fault reporting.
