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 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 (formerly 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 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.
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 services that allow you to track and control utilities to keep costs within budget. If you had a leak or running toilet, CostWatch would highlight this immediately. If you do suspect a leak, contact a licensed plumber as soon as possible.
At Cayman Water, in September 2022, the first 3,000 US gallons for a residential customer was charged at CI$18.98/1000 gal. Anything above that costs CI$22.77/1000 gal. An energy adjustment factor surcharge is applied each month that varies according to the cost of electricity. Monthly meter charges also vary depending on the size of the meter, from CI$3.50 to CI$40 for meter sizes ranging from 5/8” to 6”. Cayman Water’s website provides additional information to customers, such as current water quality data and answers to frequently asked questions.
At Water Authority - Cayman, 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 Water Authority’s website allows property owners to register for an online account and pay their bill electronically. For emergencies outside of business hours, call (345) 946 4357.
Locally bottled water is clean, affordable and comes in large blue reusable BPA free five-gallon bottles that are delivered to your home or office by the water company. You can also buy imported bottled water from grocery stores although this is being strongly discouraged as most of the plastic is not being recycled.
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 www.ionfaucet.com.
For those who need their cisterns filled, Flowers Block provides bulk water.
