What blocked-drain calls in St Helens actually look like
St Helens blocked-drain work is dominated by wet-wipe blockages and silted shared alley runs in ex-council terraces, plus root-invaded clay laterals in Rainhill and Eccleston.
Where your responsibility ends: St Helens ex-council stock runs a mix of shared and single-property laterals. Rainhill and Eccleston newer estates have single-property laterals.
When a St Helens blocked drain becomes United Utilities's problem
Drainage undertaker for St Helens: United Utilities
Under the 2011 private-sewer transfer, any pipework serving more than one property, and any lateral drain from the boundary of your property to the sewer, is United Utilities' responsibility. That covers most back-alley shared runs and every stretch under the public highway. WA10/WA11 back-alley shared runs are UU laterals — 0345 672 3723 for free clearance if you can wait.
United Utilities 24/7 sewer-flooding line: 0345 672 3723 — free of charge. Call them first if the blockage is beyond your boundary or on shared pipework.
