Improving groundwater sustainability in California

California is facing a water crisis. Not only are its reservoirs already at critically low levels due to unrelenting drought, residents and businesses across the state are also using more water now than they have in seven years. In total, California is set to lose 10% of its total water supply in th

Exploring groundwater as an option

A groundwater reservoir, known as an aquifer, is a hidden subsurface water resource and offers an opportunity to store water for future supplies. This is particularly important to secure reliable drinking water provisions in a time with more extreme weather conditions.

The Danish groundwater example

A national water supply entirely based on groundwater has required development of standardised data collection and public databases, enabling national hydrogeological groundwater models aid in the sustainable abstraction and protection of groundwater.

Good governance for sustainable groundwater management

Integrated groundwater management is key to preserving a sustainable and pollution-free resource, therefore Danish authorities and water utilities have, and have had for over three decades a, dedicated and focused approach towards protection of the natural groundwater resources. However, more and more groundwater abstraction wells are being closed due to pollution.

Sustainable utilisation of groundwater

Minimising stress on water resources and the energy consumption used to provide drinking water must be addressed at all steps throughout the drinking water production cycle. This involves abstracting the necessary quantity of water only, without abundant consumption or losses.
