           Why this guide is needed                               What the guide provides

           Our understanding of the negative impacts              This guide links the design of SuDS with the

           Pipe drainage collects and conveys water
           away from where it rains, as quickly as                This guide promotes the idea of integrating

           standards’ for SuDS.

           The responsibility for ensuring that SuDS are
           designed and implemented to a satisfactory
           standard lies with the Local Planning
           Authority (LPA).

           SuDS Designers will need to meet these
           required standards when submitting

           proposals to the LPA.
