Protecting Sensitive Waters
Under European legislation, Southern Water is reducing the levels of nitrogen nutrients in treated wastewater before it is recycled into sensitive waters.
The company is carrying out £87 million of environmental improvements at six wastewater treatment works in Hampshire and Sussex to add extra treatment processes.
The Solent and Langstone Harbour, in Hampshire, and Chichester Harbour, in Sussex, have been identified as being at risk of eutrophication where nutrients increase plant growth.
This growth can reduce the amount of oxygen in the water, causing other creatures such as fish to die.
Work started in 2005 and is due to finish by Spring 2008.

Otterbourne Water Supply Works
Underground Victorian water tunnels built more than 110 years ago have been brought into the 21st century in an improvement scheme.
A new lining has been fitted in an underground shaft at Otterbourne Water Supply Works, which pumps 54 million litres of water a day to households in Hampshire.
Two shafts more than 25 metres deep, were cleared by divers working in a cage and have been relined with a stainless steel casing.
The work has secured both the quality and quantity of groundwater from the well and tunnel for at least another 100 years.
