Cayman Water and Water Authority - Cayman supply Grand Cayman with quality water. In the case of both companies, 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.
Cayman Water serves the Seven Mile Beach and West Bay areas, while the Water Authority serves the rest of Grand Cayman and Cayman Brac (piped and trucked water). Currently piped water is only available to customers on the western end of the Island, the remainder is served by water trucks. The Authority will continue to expand its network in Cayman Brac, with a new Bluff Water Works facility.
Both companies require you to fill out an application, present your Land Registry form for proof of ownership and pay a non-refundable connection fee that varies according to the size of your water meter. Please note that both companies only allow property owners (not renters) to apply for water service. If you are a tenant, please arrange with your landlord to receive duplicate billing.
Always be sure to inspect your home regularly for dripping taps and “phantom flushing” toilets to avoid an unexpectedly high water bill. If you suspect a leak, please contact a licensed plumber as soon as possible.

The Water Authority’s website allows property owners to register for an online account.

It also provides information on outages, tips on saving water, water and sewage application forms, meter reading request forms and online fault reporting. For emergencies outside of business hours, please call (345) 946 4357.
Locally bottled water is clean, affordable, and tastes good. It can be found in grocery stores and petrol stations. Alternatively, you can install an under-the-sink well-water/city-water filter system. The 'City Water Filter' from Ion Faucet removes all the chlorine that is put in desalinated water and you can add a remineralising filter to put minerals back in which desalinated water does not have. See www.ionfaucet.com.
For those who need their cisterns filled, Flowers Block provides bulk water.
