The TUB is primarily focused on restricting household water use, but it also includes certain non-essential activities relating to upkeep of grounds of public service buildings and non-commercial workplaces. For example, activities such as filling or maintaining an ornamental fountain, watering gardens or cleaning paths and patios using a hosepipe at a workplace will be restricted. However, premises that have ponds with fish and other wildlife are able to continue to use whatever they need to keep the environment healthy.
The TUB does not impose restrictions on essential and commercial uses of water. For example, commercial window cleaners and car washes, or businesses that need water as part of their operations like pharmaceutical companies and zoos.
