Westby Reservoir Roof Refurbishment

Westby Reservoir is located in The Fylde and stores water to supply the Lancashire towns of Blackpool, Lytham and St Annes. Although the reservoir dates from the 1930s, a roof was fixed over the open reservoir approximately 50 years ago to keep the seagulls away. A major overhaul of the roof was required to keep it up to a serviceable standard.

Client: United Utilities
Location: Fylde
Value: £450k

The refurbishment of the 3,00m2 roof was let through United Utilities’ Asset Maintenance Service (AMS) Framework and involved the project management to coordinate many specialist operations including –

Overhaul and repair to the corrugated sheet roof including the replacement of over 20,000 fixing rivets and hook bolts
Concrete repair works to the structure
Application of new sprayed waterproof coating to roof gutters, perimeter channels and flat roof areas around access hatches
Replacement of flashings and sealing of gaps around the perimeter with new foam filler blocks
Repointing of brickwork and repointing of all expansion joints to the reservoir floor and walls
Refurbishment of existing access ladders and handrails

All works within the covered reservoir were carried out under a highly regulated confined-space policy. Internal works were undertaken to strict levels of hygiene and full cleaning of the reservoir completed before re-introducing new supplies of drinking water.
