Drainage renewal and structural relining at Barnsbury Estate

First Action Drainage delivered a major overhaul of the drainage system at Barnsbury Estate. The 12 week programme combined pipe replacement, structural relining, drain cleaning and surface repairs, with hired welfare facilities supporting the site management team and engineers.

The estate required a coordinated programme covering underground pipework, access chambers and the roads above them. The scope called for both excavation and structural relining, alongside descaling and cleaning of existing drains. Managing these different workstreams required a dedicated site presence throughout the programme.

Pipework renewal  We excavated and renewed 120m of 100mm and 150mm vitrified clay pipework, replacing it with new vitrified clay pipework of the same diameters.

Structural relining and cleaning  We completed over 320m of structural drain relining and more than 100m of drain descaling and cleaning. These works formed part of the wider renewal programme across the estate.

Manholes and surface repairs  The programme included multiple manhole replacements and road repairs, including asphalt reinstatement. A designated site area accommodated hired welfare facilities for our management team and engineers.

The completed programme brought together 120m of pipe renewal, over 320m of structural relining and more than 100m of cleaning and descaling within a 12 week delivery period. Manhole replacements and road repairs completed the associated infrastructure works.
