How often does sewage spill near Westbourne?
The Lumley Road pumping station is the only monitored storm overflow within 1.5 km of a Westbourne postcode, on the water companies' 2025 returns to the Environment Agency. It empties into the River Ems and recorded no spills in 2025 or 2024. A storm overflow lets diluted sewage out into a river or the sea when heavy rain overloads the sewers. The counts use the Agency's method, in which the first 12 hours of a spill count as one and each 24 hours after that as another.

How clean is the water for swimming near Westbourne?
Westbourne has no designated bathing water of its own. The nearest beach the Agency does rate is West Wittering, a median 9.7 km from Westbourne's postcodes in a straight line, rated Excellent for 2025; next is Hayling Eastoke, 9.8 km away and rated Excellent. A rating covers the last four summers of samples, not any one day, and new ratings come out each November.
How energy efficient are homes in Westbourne?
About the same as the area as a whole, on their energy performance certificates. Of the 706 homes in Westbourne with a certificate on the government register, 47% are rated C or better, against 50% across the Chichester council area; the most common rating is D. Mains gas heats 87% of the 706 whose main fuel is recorded, and electricity 9%. 31 have a heat pump. Of the 677 whose certificate records it, only 8% have no mains gas connection; 29 certificates do not say. 5% have solar panels, and eleven have solar water heating. A certificate is only made when a home is sold, let or built, so homes that rarely change hands are missing, and an old one shows a home as it was then. Each home's latest certificate is used: issued between 2008 and 2026, half of them since 2019.
