This project in Cambourne, Cambridgeshire demonstrates that SuDS work and should cost less than conventional piped drainage in terms of construction, maintenance and whole-life costs. It also highlights the robust performance of concrete block permeable paving with minimal maintenance requirements – and lower whole-life costs.
It demonstrates the use of as many SuDS techniques as possible, including concrete block permeable paving, used in combination with other elements to form an effective management train. Despite being retro-fitted to a conventional housing layout, the SuDS are fully integrated with the landscape and have proved to be effective in managing rainfall as well as popular with residents.
