Creating a water-sensitive north-west Cambridge master plan

Abstract

An integrated approach to water management and urban design has actively been sought in the development of the master plan for a major urban extension in north-west Cambridge. A multidisciplinary team of urban designers, landscape architects, engineers, ecologists and planners have developed a water-sensitive urban design strategy for the site. From the concept stage, integrated sustainable drainage measures and extensive green corridors have been integrated into the site, to treat and store surface water above ground while also supporting urban design and place-making aspirations. A site-wide strategy for water management is also being developed to utilise opportunities to integrate the entire water cycle and progress towards water neutrality, including consideration of site-wide wastewater recycling for non-potable reuse; site-wide stormwater harvesting, using sustainable urban drainage systems features to filter water for non-potable reuse; and specifications for water efficiency in buildings and the landscape. The case study demonstrates how the consideration of water management upfront can be used to shape the spatial layout, utilities and infrastructure strategies, and the urban design vision for new development.
