Westby Reservoir Roof Refurbishment
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.
