Terrace Water Storage Tanks for Buildings and Rooftops
Prefabricated steel tanks assembled on terraces and elevated structures — for a building’s domestic supply or fire water reserve, planned with your structural engineer.
- Assembled in place
- Structural coordination
- Domestic or fire reserve
Storage where the building needs it
Many buildings store water at roof level so it can feed the building by gravity, or hold a fire water reserve close to the floors it protects. A terrace tank has to suit the roof as much as the volume.
Because AVM tanks are built from prefabricated panels, the tank can be taken up in panel sets and assembled on the terrace or an elevated platform, subject to site access — rather than lifting one large finished vessel.
AVM Prefabricated Modular Tanks LLP plans each terrace tank around the required capacity, the space available and the structural limits confirmed by the building’s structural engineer.
Key features of terrace water storage tanks
Assembled in place
Panel sets are taken up and bolted together on the terrace.
Structural coordination
Tank size and position planned against the slab or platform design.
Sized to the building
Capacity planned for domestic demand or the fire reserve.
Access & inspection
Ladders, manholes and roof access for cleaning and checks.
Connections planned
Outlets for gravity supply, fire piping, overflow and drain.
Covered tank
Roofed construction keeps stored water clean.
Where terrace tanks are used
Applications to be confirmed with AVM for each project include:
- Residential towers & societies
- Commercial & office buildings
- Hospitals & institutions
- Hotels
- Factory rooftops
- Fire water reserves at roof level
Why modular steel suits a rooftop
No large lift
Panels travel in compact sets instead of one large finished tank.
Planned with the structure
Tank size and support are coordinated with the structural design.
Domestic or fire duty
The same system can hold the building’s supply or its fire reserve.
Planning a terrace tank
The structure sets the limits. Before ordering, confirm with your structural engineer and AVM:
Consider these factors
- Permissible load on the terrace or platform
- Available area and height
- Access route for panel sets
- Required capacity and use (domestic, fire or both)
- Connections, overflow and drain routes

Frequently asked questions
A tank installed on a building’s terrace or an elevated platform to store water for domestic supply or a fire reserve.
It depends on the structure. The building’s structural engineer must confirm the permissible load before the tank is sized and positioned.
Panels are taken up in sets and bolted together on the terrace, subject to site access.
Yes, where the fire protection design calls for a roof-level reserve. Capacity and connections follow that design.
