Water Tank Installation Singapore | Tank Contractor & Supplier

Water tank contractor Singapore

Complete water storage tank installation

Water tank installation covers far more than lifting panels into place. It means selecting the right tank material for the water being stored, sizing the tank to the building's demand, preparing the plinth or steel base correctly, bolting and sealing the panels, fitting the internal and external ladders, vents, level controls and pipework, then testing the tank for leaks before handover.

Waves Fluid Engineering Pte Ltd installs panel-bolted water storage tanks across Singapore, from potable water tanks in condominiums and commercial buildings to fire, sprinkler, hosereel, cooling tower, NEWater and chemical storage tanks in industrial facilities. Because we also install and service water pump systems, we can take responsibility for the complete storage and pumping installation rather than leaving you to coordinate two contractors.

We handle new installations, tank replacement, panel repair and leak rectification, and the annual inspection and cleaning that PUB requires, whichever contractor originally built the tank.

Which water tank do I need?

In short: FRP / GRP panel tanks are the standard choice for potable water storage in Singapore and must comply with SS 245:2014. HDG and bitumen painted pressed steel tanks are used for fire, sprinkler and hosereel water to SS 22. SS304 suits non-potable duties such as fire, chemical and treated water, while SS316 is used for drinking water and food-grade applications.

Quick comparison

Which water tank material for which application?

Tank material is chosen by what the water is used for and the standard the installation must meet, not by price alone. This table summarises the usual selection in Singapore.

Tank type	Typical application	Standard referenced	Notes
FRP / GRP (SMC panel)	Potable water, NEWater, cooling tower, rainwater	SS 245:2014	Most common domestic and commercial tank in Singapore; insulated option available
HDG pressed steel	Sprinkler, fire and hosereel water	SS 22:1979, SCDF requirements	Hot-dip galvanised finish, suitable for outdoor installation
Bitumen painted steel	Indoor sprinkler, fire and hosereel water	SS 22:1979, SCDF requirements	Black enamel bituminous coating, for indoor plant rooms
SS304 stainless steel	Hosereel, sprinkler, fire, chemical, treated water	Grade 304 stainless	Non-potable duties; strong corrosion resistance and long service life
SS316 stainless steel	Drinking water, potable water, food processing	Grade 316 stainless	Higher corrosion resistance than 304; used where potable or food-grade quality is required

FRP, GRP and SMC are not three different tanks

FRP stands for fibre reinforced plastic and GRP for glass reinforced plastic. They describe the same tank. SMC (sheet moulding compound) is the process used to make the panels.

Water tank panels

Panel sizes and tank configuration

Panel bolted tanks are assembled from modular panels, which is what lets us build a tank to fit an awkward plant room and bring it in through a normal doorway. FRP / GRP panels are available in the following sizes.

1m x 2m (H)

Standard large panel

1m x 1m (H)

Standard panel

1m x 0.5m (H)

Height adjustment

0.5m x 0.5m (H)

Fine adjustment

This range of panel sizes gives a wide choice of tank dimensions, so the tank capacity can be matched closely to the building's storage requirement and the space available. We also supply individual replacement panels, so a single cracked or leaking panel can be changed without rebuilding the tank. See our FRP / GRP tank page for full panel details and repair options.

Site requirements

What a correct tank installation involves

Most tank problems that appear years later start at installation. These are the points we check and get right on every job.

Plinth and base

1m centre-to-centre plinth spacing is standard. Where 2m centre-to-centre is used, an I-beam skid base is required to carry the load.

Tank height limits

Potable water tank height in Singapore is restricted to a maximum of 4m. Non-potable tanks have no such restriction.

Safety features

Tanks 3m or higher require a perimeter guard rail on the roof panels and a safety cage on the external ladder.

Air vents

Each compartment normally has one air vent, though a consultant may specify more than one per compartment.

Compartments

Dual-compartment tanks let one cell be isolated for cleaning or repair while the other keeps the building supplied.

Access and security

Lockable manhole covers, internal and external ladders, and level controls fitted so the tank can be inspected safely.

Regulatory compliance

PUB compliance and annual tank inspection

Water storage tanks in Singapore are regulated, and the responsibility sits with the building owner or MCST. Under the Public Utilities (Water Supply) Regulations and SS 636: Code of Practice for Water Services, whoever is responsible for a water service installation with a water storage tank must engage a Licensed Plumber at least once every 12 months to inspect the tank, clean and disinfect it where necessary, and certify it.

PUB carries out random inspections to check that tanks are properly maintained and secured, and issues reminder emails for the annual certification. You should not wait for the reminder before arranging the work. Note that the mandatory annual inspection does not apply to landed residential properties and certain private housing arrangements, though those owners are still responsible for keeping the tank clean and safe.

For new installations, tanks storing potable water must comply with SS 245:2014, and fire, sprinkler and hosereel tanks are built to SS 22 and SCDF requirements. We handle the PUB submission as part of the installation where the scope requires it.

FAQ

Frequently asked questions

Common questions about water tank installation, repair and maintenance in Singapore.

What types of water tanks are used in Singapore?

The main types are FRP / GRP (SMC panel) tanks, HDG pressed steel tanks, bitumen painted pressed steel tanks, and stainless steel SS304 and SS316 tanks. FRP / GRP is the most common for potable water storage, while pressed steel tanks are typically used for fire, sprinkler and hosereel water. Glass fused steel and insulated panel tanks are also available for specialised applications.

Which water tank is best for drinking water?

For potable water storage in Singapore, FRP / GRP panel tanks compliant with SS 245:2014 are the standard choice. Where a higher specification is required, such as food processing or pharmaceutical use, SS316 stainless steel tanks are used because of their greater corrosion resistance. SS304 is generally used for non-potable duties such as fire, chemical and treated water.

What is the difference between FRP, GRP and SMC?

FRP and GRP describe the same tank. FRP stands for fibre reinforced plastic and GRP stands for glass reinforced plastic. SMC stands for sheet moulding compound, which is the process used to manufacture the panels. So an FRP tank, a GRP tank and an SMC panel tank all refer to the same product.

Is annual water tank inspection mandatory in Singapore?

Yes, for applicable installations. Under the Public Utilities (Water Supply) Regulations and SS 636, the person responsible for a water service installation with a water storage tank must engage a Licensed Plumber at least once every 12 months to inspect the tank, clean and disinfect it where necessary, and certify it. PUB also carries out random inspections. The requirement does not apply to landed residential properties and certain private housing arrangements, though those owners remain responsible for keeping the tank clean.

How long does a water tank installation take?

It depends on the tank size, the access route into the plant room and whether an existing tank has to be dismantled first. A straightforward panel tank can be assembled in a few days, while larger or restricted-access installations take longer. We confirm the programme in the quotation after the site visit.

How much does water tank installation cost in Singapore?

There is no single price. Cost depends on the tank material, the capacity required, whether the base or plinth needs preparation, access and rigging into the plant room, and whether an old tank has to be removed. We provide a written quotation after a site visit, at no obligation.

Can a leaking water tank panel be replaced without a new tank?

Yes. Panel bolted tanks are modular, so a single cracked or leaking panel can usually be replaced without rebuilding the tank. We carry out leaking panel replacement, joint and sealant rectification and other tank repair works. If the tank is at the end of its service life, we will advise on replacement rather than repeated repairs.

What panel sizes are available for FRP tanks?

FRP / GRP panels are supplied in 1m x 2m (H), 1m x 1m (H), 1m x 0.5m (H) and 0.5m x 0.5m (H). This range allows the tank dimensions to be matched closely to the available space and the storage capacity required, which is useful where the plant room is an awkward shape.

Is there a height limit for water tanks in Singapore?

Potable water tank height is restricted to a maximum of 4m. Non-potable water tanks have no such restriction. Separately, any tank 3m or higher requires a perimeter guard rail on the roof panels and a safety cage on the external ladder.

Do you deliver water tanks as well as install them?

Yes. We supply and deliver the tank panels, fittings and accessories to site and carry out the installation with our own team. Because panel tanks arrive as modular components, they can be brought through normal doorways and assembled inside the plant room.

Do you service tanks installed by another contractor?

Yes. We repair, clean, inspect and maintain existing water tanks regardless of who originally installed them, and we can advise whether repair or replacement is the better option for your building.

What warranty do you give on a new water tank?

Newly installed FRP / GRP water tanks come with a two-year warranty from the date of installation, subject to terms and conditions. Products and spare parts we supply are from globally recognised manufacturers.
