Water

The water that is extracted is saline groundwater and 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 approved by the NSF International (National Sanitation Foundation) 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 with piped and trucked water. Currently, piped water is only available to customers on the western end of Cayman Brac, up to Watering Place, while the remainder is served by water trucks. Water 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.

New Customer Portal

In February 2024, Water Authority - Cayman announced the release of its new Customer Portal, providing customers better management of their Water Authority accounts. Their easy-to-use interface allows customers to view and pay their bills, schedule payments, pay for multiple accounts at once, manage tenant accounts, request and track service orders, review consumption history and more, including the self-registration of tenants.

Customers with an existing online access to their Water Authority account will receive an email with instructions for accessing this new portal. For those who do not have an online account with Water Authority, including tenants, are encouraged to sign up. Visit the Water Authority website to learn more.

Water Costs

Water costs are typically lower than electricity, but an undetected leak, such as a running toilet or faulty irrigation system, can quickly inflate your water bill to far exceed other household costs. Always be sure to inspect your home regularly for dripping taps and ‘phantom flushing’ toilets to avoid an unexpectedly high water bill.

CostWatch provides monitoring and automation services that allow you to track and manage your utilities, keeping costs within budget. If you have a leak, running toilet or irrigation fault causing high water usage, CostWatch will notify you quickly and could even stop it automatically. If you do suspect a leak, contact a licensed plumber as soon as possible.

Bottled Water

Locally bottled water is clean, affordable and comes in large blue reusable BPA-free five-gallon bottles that can be delivered to your home or office. Flowers Bottled Water (Tel: (345) 949 8688) sells purified, chlorine-free water in five-gallon BPA-free bottles. You can also buy imported bottled water from grocery stores. However, this generates a huge amount of plastic waste, so is discouraged. If you do purchase water from supermarkets, take the time to properly recycle your waste. See Being Green for information on recycling in Cayman.

Alternatively, you can install an under-the-sink water filter system for well water or city water. 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 in the minerals that desalinated water does not have. See the Ion Faucet website for more information.

Bulk Water

For those who need their cisterns filled, Flowers Block provides bulk water.
