ting legal obligations under the EU bathing water directive, has involved t
he company in a pound 266 million investment programme around its coastline
. This paper describes the programme, called project Clearwater, and the ra
nge of engineering solutions devised. It indicates how attention paid to ma
rine modelling, linked to engineering work on intermittent discharges as we
ll as the continuous discharges, has led to a successful outcome, namely th
e first UK water company to achieve 100% compliance at its designated bathi
