Peterborough City Council has installed the Arborflow tree pit system – a flow-control chamber positioned on the outfall of tree pits - to help provide a more cost-effective water management solution as part of the Flecton Quays mixed use development.
The Council set up the Peterborough Investment Partnership to work with businesses and householders to develop this project; and it says the implementation of innovative SUDs has saved almost £1m, having negated the need for excavations and piped solutions. The other solutions implemented include permeable paving and swales.
"SuDS has to work for a variety of stakeholders, it has to be cost-effective and if we want it integrated across a variety of land uses, there will be compromise, design change, and multidisciplinary working required," GreenBlue says.
"You won’t always be able to achieve the optimum design given site constraints, but this should not deter us from striving to achieving a more natural means of managing flood risk, of coping with surface water during those heavy rainfall events."
