Water is an essential component of wine production. It is a valuable and costly resource and its management with regards to sustainability can be separated into two aspects:

1. Water use reduction: in order to conserve water resources and reduce costs
2. Wastewater reuse, treatment and recycling: to minimise waste, avoid pollution and reduce costs of water use and wastewater treatment.

Good water management has environmental and economic benefits.
Water management starts with effective monitoring of the quantity used in order to set targets for reduction, followed by development and implementation of strategies and methods to reduce uptake and increase reuse and recycling.
