The site of a £300 million scheme to bring cleaner seas to Sussex has been rated as one of the best in the country.

This is the highest score a Southern Water site has ever achieved and puts it in the top two per cent in the country. The new works are being built on behalf of Southern Water by 4Delivery, a consortium between Costain, Veolia and MWH.

The CCS is an independent body that aims to improve the image of construction.  It judges a range of factors associated with the site and the way it is managed by the company and contractors including how clean, safe and environmentally responsible it is, whether it is respectful and considerate to its neighbours and how responsible and accountable it is.

Anthony Harris, the CCS inspector who visited the site, said: “An excellent site-an example for others to follow.”

During the assessment the site scored top marks in three of the eight categories – ‘A good neighbour’, ‘Safe’ and ‘Respectful’ – which look at both the consideration for the local community and the workers on site.

Ben Green, project manager for Southern Water, said: “This is the fourth assessment by the CCS scheme assessor and each time our score has increased. It is a great acknowledgement of the hard work by everyone on the site to ensure that we minimise any disruption caused by the construction and that our staff go home safely every day.”

The new wastewater treatment works are part of Southern Water’s £300 million environmental improvement scheme to bring cleaner seas to Sussex. The project also includes 11 kilometres of new sewer tunnel, three pumping stations and a new 2.5 kilometre long sea outfall.

4Delivery is carrying out a programme of environmental improvement and water quality schemes for Southern Water until 2015. The improvements are taking place across Kent, Sussex, Hampshire and the Isle of Wight.
