Understanding Your Property's Drainage Responsibilities
across Liverpool, Sefton, Southport, and the Wirral, much of the Victorian sewer network is over 150 years old. Knowing where your private responsibility ends and the public water authority's begins is essential when dealing with a blocked or collapsed pipe.
Private Drains
Homeowners and commercial property owners are generally responsible for the internal pipework and underground drains that exclusively serve their property up to the boundary or the point where they connect with shared pipes.
Shared Sewers & Lateral Drains
Pipes that carry wastewater from more than one property, or sections of drain located outside your property boundary, are typically managed by the regional water and sewerage undertaker.
Building Over Sewers & Surveys
If you are purchasing a property or planning building work near an existing drain, a CCTV drain survey maps pipe locations and checks structural condition for compliance and peace of mind.
Compliant Repairs
Whether carrying out no-dig CIPP drain relining or a full drain excavation, our fully insured engineers work strictly to UK safety and building standards.
