The water cycle

The water system

The water system is the natural cycle of water: the continuous movement of water on, above and below the surface of the Earth. Water passes through different processes, from rain water to surface water and ground water. Our responsibilities start with rain water. We keep track of the levels of ground water and surface water. These levels may not vary too much. This is how we prevent floods and make sure people can continue to sail on rivers and channels. 

The water chain

The water chain is also a cycle, however it is set up by people. Waternet produces tap water and supplies this to the residents of Amsterdam and surrounding area. We also ensure that the waste water is transported to the waste water treatment facilities via the sewer system.

1. The water chain starts with the process of retrieving water from the ground, rivers and lakes.
2. We treat this water to make it safe to drink or so that it can be used for other purposes.
3. Afterwards, the water flows down the drain or toilet. This waste water ends up in the sewer system and is transported to a waste water treatment facility.
4. From there, the water is returned to the surface water. The cycle is complete.
