What drainage in Hemel Hempstead actually looks like
Your water company
Thames Water serves Hertfordshire and the Thames Valley. It's responsible for public sewers and the lateral drains beyond your boundary — including build-over agreements.
Who's responsible? →Local ground conditions
Hemel Hempstead 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
Hemel Hempstead mixes older and newer housing, so drain age and material vary. A CCTV survey confirms the condition of whatever drains your property has.
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.
