NORTH TYNESIDE BATHING WATERS SCHEME

The North Tyneside bathing waters' scheme reduces the frequency and qu ality of storm sewage which is discharged inshore from existing interc eptor sewers along the coast. Flow-simulation modelling is applied to the existing system to determine the frequency and volume of intercept or sewer overflow against a range of storm intensity and return period s. The models are extended to an evaluation of new systems of storm-se wage management. An optimized solution is described in which new storm sewers are utilized for the storage of all storm-sewage overflow disc harges prior to screening and pumping of the storm sewage to sea via a n outfall.
