National construction and engineering company, JN Bentley, is working with Anglian Water on a major 63km pipeline project to take water across Lincolnshire – supplying drinking water to homes and businesses in Boston, directly from the Covenham reservoir near Louth.
Work has now begun on site for the first 40km section of pipeline – linking the Covenham and Miningsby Reservoirs. Engineers are busy welding together 18m sections of pipe ready to be laid underground with work expected to finish later this year. The second 20km section will be installed in 2013; stretching from Miningsby Reservoir to Boston where it will be linked to the existing water distribution system.
The new pipe is necessary to cope with greater demand for drinking water in south Lincolnshire which is more densely populated. In particular, the scheme will provide an important additional water supply for Boston residents. The town’s population is expected to grow significantly over the next 25 years and the scheme is therefore essential to address the challenges posed by low rainfall and the needs of an expanding population. When complete, the pipeline will be able to carry up to 26 million litres of water every day.
The £40m project, which is one of a number of large capital investment projects planned by Anglian Water, supports the water company’s ‘Love Every Drop’ campaign. To support this initiative, which highlights the impact of water consumption and its effect on climate change, Anglian Water challenged the companies working on the pipeline project to reduce the scheme’s embodied carbon emissions by 50%.
Teams from JN Bentley and Mott MacDonald, the engineering and development consultancy, have been working closely together to find an affordable solution that successfully halved the carbon used. This collaboration led to the development of two new products which reduced the use of concrete and lessened the environmental impact of the project. As a result, the scheme has scored a provisional ‘excellent’ rating from the CEEQUAL assessment scheme for the design phase of the project. The site team is continuing the challenge, using additional collaborative tools and the CEEQUAL process to focus their environmental delivery of the project - identifying further opportunities and turning them into reality with the help of the whole project delivery team.
Both JN Bentley (jnbentley.co.uk) and Mott MacDonald were previously involved in the design and construction of Anglian Water’s 41km Wing pipeline and have been able to draw on this expertise for the Covenham to Boston pipeline project.
