This article focuses on the development of an integrated waste water management plan to improve the water quality of bathing beaches situated at the mouth of the Ribble Estuary in England. The effects of discharges from the most significant of the existing discharges to the estuary were investigated by means of a series of tracer releases carried out during 1988 and 1989. The main findings are: discharges from Preston Sewage Treatment Works (STW) could be detected in the outer estuary in the waters off Lytham, but not off Southport; discharges from Southport STW were well dispersed in the outer estuary and were not detectable in the waters off either Southport or Lytham; and discharges from Fairhaven Tanks were detectable in the waters off Lytham but not Southport, and during a period of strong south westerly winds could also be detected in water further north along the Fylde Coast. The model used to simulate the dispersion of effluent from outfalls to the estuary and coastal waters was developed by the Water Resource Centre. The dispersion processes are represented by a random walk procedure superimposed on the water movements derived from a hydrodynamic model covering the majority of the Irish Sea. |
