What drainage in Middlesbrough actually looks like
Your water company
Northumbrian Water serves the North East (Teesside). It's responsible for public sewers and the lateral drains beyond your boundary — including build-over agreements.
Who's responsible? →Local ground conditions
Middlesbrough has variable ground and higher rainfall, which puts extra pressure on surface-water drainage. A percolation test decides whether a soakaway is viable.
Soakaway rules & costs →Local housing age
Middlesbrough has a high share of older terraced housing with ageing clay drains, prone to cracks and root ingress — exactly what a CCTV survey finds.
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.
