Pevensey Haven rises at the confluence of two smaller streams in the neighbourhood of Rickney (BN27)—Hurst Haven to the northeast, and Glynleigh Sewer to the west. Pevensey Haven flows a southerly course before turning east; after it receives the waters of Chilley Stream (east), it commences a southeasterly course into the civil parish of Pevensey. Pevensey Haven then turns south and flows underneath the Pevensey Bypass section of the A27 road via a culvert, where it receives the waters of Old Haven. When Pevensey Haven reaches Westham, it curves east to become known as Salt Haven.[2][3]
