At Alconbury, initial discussions with Anglian Water identified the need to provide extensive off site works to deliver a suitable supply of clean water to the site. During the course of these discussions, we collectively identified an alternate and innovative approach to reinforce Anglian Water’s wider existing network of clean water distribution by running a new strategic reinforcement main through our land from Huntingdon rather than along the existing adopted highway of Ermine Street through the Stukeleys, which saved the excavation of over 4km of public highway with the commensurate disruption that would have caused to both transport and general movement over a nine month period. Undertaking the design and construction of the works in this manner not only positively corrected the potential environmental impact of the scheme but also contributed positively to the financial viability of the strategy for the overall development.
