A major contract for the supply of CO2 will see the industrial and special gases company BOC help Severn Trent Water sustain the supply of good quality drinking water to the city of Birmingham (UK).

The five year contract awarded to BOC\\$quot;s water processes team after lengthy tendering, allows for an annual supply of 2300 tonnes of CO2 to the Severn Trent Water Frankley water treatment plant which supplies drinking water to homes and businesses around the city.

CO2 is crucial to Severn Trent\\$quot;s long term plans to manage the supply of good quality drinking water and improve and modernise the 46,000 kilometres of water pipes. Mixing lime, water and CO2 hardens the water and helps to prevent mineral contamination especially from lead water pipes.

The new contract strengthens the ties between the two companies with CO2 just one of a number of products BOC supplies Severn Trent Water for the treatment of drinking water and wastewater.

BOC\\$quot;s technical manager Cedric Hanson said: \\$quot;BOC works closely with its water customers, providing expertise and technical solutions in water treatment to help water utilities meet environmental and consumer targets.

\\$quot;All water utilities have stringent water quality targets so it is important to have a secure supply of CO2 to ensure water is kept free of contaminants and the life of an extensive network of pipelines is sustained.\\$quot;

BOC account manager Tim Wigfall added: \\$quot;This is a major win for BOC and comes from the water processes team building a thorough understanding of Severn Trent Water over the past five years. Over the course of the contract we will be looking for further opportunities to strengthen our partnership with the water utility.\\$quot;

Matthew Griffiths from Severn Trent Water said: \\$quot;We are investing £120 million every year for the next five years on water management, including improvements to the network of water pipes, in order to sustain the supply of high quality drinking water to our customers.

\\$quot;BOC\\$quot;s water processes team is contributing to that investment. Through a constant drive for efficiency and the expertise of BOC\\$quot;s technical, engineering and safety services Severn Trent Water is already seeing significant benefits.\\$quot;
