What drainage in Birmingham actually looks like
Your water company
Severn Trent serves the Midlands including Birmingham. It's responsible for public sewers and the lateral drains beyond your boundary — including build-over agreements.
Who's responsible? →Local ground conditions
Birmingham sits on mixed ground with localised clay, so soakaway viability varies by area. A percolation test is essential before any surface-water work.
Soakaway rules & costs →Local housing age
Birmingham has a substantial stock of Victorian and Edwardian terraces. Older clay drains in this housing are more 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.
