What drainage in Southampton actually looks like
Your water company
Southern Water serves Hampshire. It's responsible for public sewers and the lateral drains beyond your boundary — including build-over agreements.
Who's responsible? →Local ground conditions
Southampton has chalk and gravel soils in places, with soakaway viability that varies by location. A percolation test is essential before any surface-water work.
Soakaway rules & costs →Local housing age
Southampton has a high share of Victorian and Edwardian terraces. Older clay drains here are prone to cracks, displaced joints and root ingress — what a CCTV survey pinpoints.
Why drains keep blocking →When to book
Blockages spike in December–January as festive fat and wipes hit the sewers (Water UK). Autumn is the best time to survey — before winter rainfall raises the risk of flooding and backing up.
