The construction of the Cardiff Bay Barrage created a freshwater lake with unique water quality and associated groundwater management challenges.  For example, the Cardiff Bay Barrage Act’s requirement to maintain dissolved oxygen levels above 5mg/l in all places and at all times is not known to exist anywhere else in the world.  Similarly, the groundwater monitoring system installed and the database containing groundwater level, river, bay and sea level and rainfall data is the largest urban system of its kind in the world. Permanent groundwater control systems have also been installed. Also, the undertaking of condition surveys of over 20,000 properties between November 2001 and November 2002 is believed to be the largest project of its type undertaken. 

The Cardiff Harbour Authority’s commitment to environmental management is demonstrated by it becoming the first Harbour Authority to attain ISO 14001 (Environmental Management Systems) accreditation in March 2004.

Further information regarding the Harbour Authority’s environmental management policies and initiatives may be accessed under Groundwater, Groundwater Protection, Water Quality, and Conservation pages.  The latter also provides information on the Harbour Authority’s renewable energy projects and sustainability strategy amongst others.
