North Tyneside Bathing Waters’ Scheme

Abstract

The North Tyneside bathing waters’ scheme reduces the frequency and quality of storm sewage which is discharged inshore from existing interceptor sewers along the coast. Flow‐simulation modelling is applied to the existing system to determine the frequency and volume of interceptor sewer overflow against a range of storm intensity and return periods. The models are extended to an evaluation of new systems of storm‐sewage management. An optimized solution is described in which new storm sewers are utilized for the storage of all storm‐sewage overflow discharges prior to screening and pumping of the storm sewage to sea via an outfall.
