Much of southern West Sussex sits above the chalk aquifer — one of the most productive groundwater sources in England. Boreholes in the Chichester and Arundel areas typically reach productive water between 30m and 80m depth. The Wealden Clay belt around Billingshurst, Kirdford and Horsham requires deeper drilling into the underlying sandstone, and water from this geology often requires iron and manganese treatment before use. The Lower Greensand around Pulborough and Storrington offers good yields at moderate depth.
Every site is different. A desk-based geological assessment is always the starting point for any project.
