This paper describes the current groundwater situation and warns that the unsustainable use of groundwater stands to significantly impact a host of hydrological, ecological and other natural resources and services, including freshwater bodies, and aquatic, riparian, transitional, and terrestrial ecosystems.

The Water Integrity Network is seeking information on initiatives addressing corruption related to water and climate change for the Water Integrity Case Information Sheet series.

Case studies should address questions such as 

What obstacles are rendering water-related climate change adaptation strategies inadequate or inequitable?; What types of initiatives have been put in place to avoid or address climate-related water integrity issues (regulation, policy, monitoring, advocacy, project design, etc.)?; How do local, national, and international groups and organisations tackle such problems?; and What other special problems is climate change implicating for water integrity?

The deadline is 1 June 2009.

The principles and ideas presented have been shown to be effective in increasing the capacity of water, and are based on extensive experience in upgrading a variety of treatment plants throughout the world. The procedures proposed apply not only to the optimization of existing treatment plants but also to the design of new ones.

The term "Operation and Maintenance" has been used as a general concept covering a wide range of activities carried out by utilities, government and communities in order to sustain their services and to maintain existing capital assets.
