What drainage in Colchester actually looks like
Your water company
Anglian Water serves Essex and the East of England. It's responsible for public sewers and the lateral drains beyond your boundary — including build-over agreements.
Who's responsible? →Local ground conditions
Colchester sits on clay-influenced ground — often poor for soakaways and a higher risk for subsidence and root ingress. A percolation test decides.
Soakaway rules & costs →Local housing age
Colchester has a high share of Victorian and Edwardian housing. 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.
