Common blocked drains london problems in Canary Wharf
- ✓ Fat-and-oil (FOG) blockages from the very high density of restaurant kitchens in Jubilee Place, Crossrail Place, and surrounding food courts
- ✓ Shared riser and stack blockages in high-rise residential towers — a single blockage typically affects multiple flats on the same stack
- ✓ Tidal-surcharge backup into basement plant rooms and lower-ground commercial units when check valves are missing or have failed
- ✓ Wet-wipe and sanitary-product accumulation in shared multi-tenant stacks, particularly in older 1990s podium developments
- ✓ Combined surface-water and foul drainage overload during heavy rainfall on estate-managed pump stations
