Water Sub-System in the Sustainable Texel Island

It is consider possible to develop a fully sustainable water cycle sub-system, however water is just one component- module- part of the true holistic urban concept.

Water cycle subsystem for Texel design, as one module- unit of the whole system, although it is designing independently from the other sub-systems, it still corporate with them (more or less) creating an integrated whole. All sub-systems are characterised by synergy and interdependence.

Water Cycle management is closely linked with the whole urban development and consequently almost with all the other sub-systems.

A lot of economic activities in a city are dependent on a reliable supply of water. But there are also other examples of urban sectors such as energy, waste, health, transport etc. that are influenced by, and have an influence on, the successful management of water in a more or less obvious way.

The most efficient way to explain the relation between water cycle sub-system and the others sub-systems is by referring examples.

- Building Environment: The construction of new building developments creates additional water demand and the need for new distribution infrastructure.

- Health & Happiness: A reliable water supply of sufficient quality and quantity is essential for the health of a city’s population.

- Economic development: Many industries rely on a large supply of fresh water for production, washing and cooling purposes. Industrial productivity and growth therefore depends on a reliable source of supply.

- Public Space: Land uses such as parks and gardens rely on large quantities of fresh water for irrigation.

- Host: Tourist destinations, like Texel, can experience huge peaks in water demand during the high season. Water supplies need to be able to cope during these peak periods if hotels and other facilities are to remain operational.

- Energy: Water availability from reservoirs may be restricted due to conflicting interests from hydro-power generation. Water treatment and pumping costs are also dependent on a reliable supply of energy.

- Materials & Waste: Poorly managed urban waste can cause the pollution of ground and surface water sources that a city’s water supply may be reliant on

- Mobility: Most distribution pipelines run underneath roads and pavements. Rehabilitation of the network and the fixing of leaks cause disruption to the flow of traffic.
