They are NEWater, desalinated water, imported water from Johor and local catchment water.
A catchment is an area or a structure for collecting water, most often for collecting rain water.
Every area is a water catchment area to a greater or lesser extent.
The four national taps are the Local Catchment water, Imported water, NEWater and Desalinated water.
Local catchment water has advantages such as reducing reliance on distant water sources, promoting self-sufficiency in water supply, and decreasing energy costs associated with water transportation. Additionally, it helps to conserve water resources, enhance water quality through natural filtration processes, and reduce the risk of water scarcity during droughts.

Via the mouth of the river into the sea. Also as a watershed just describes where surface water travels in the catchment water can infiltrate into the rock and travel into a different catchment / watershed.
Some advantages of a local catchment include reduced transportation costs and carbon emissions associated with importing goods, supporting local economies and businesses, and promoting food security and resilience by ensuring a local supply of resources.
Catchment yield refers to the amount of water that flows out of a watershed or catchment area as surface runoff, groundwater flow, or streamflow. It is typically measured in volume or depth over a specific period of time and is influenced by factors such as precipitation, geology, land use, and vegetation cover within the catchment. Understanding catchment yield is important for managing water resources and assessing the potential impacts of land use changes or climate variability on water availability.
