Phuket has a government water supply network with direct metered supply, however it does not cover the entire island. So there are generally three main possibilities for water supply; governement metered water supply, deep well water and delivered by water truck.
Being connected directly to the government water network is generally the optimum solution, which means a direct metered supply to your property at "government rates", which is between 10 baht and 22 baht per unit (1,000 litres), depending on your area.
The most important utility - and potentially the most costly in terms of new installations - is electricity. All other things being equal, land prices tend to be higher if there is an existing electricity supply, or electric has been brought to the boundary of the land. The next thing to check is whether the Phuket land for sale has single-phase or three-phase electricity. Important Tip: Three-phase electricity is superior. Three-phase is more efficient for high loading, like running multiple air-conditioners together with swimming pool systems.
