Drinking and domestic water storage, including transfer tanks and rooftop tanks.
General make-up and selected process-water storage for commercial and industrial sites.
Modular water storage for rainwater harvesting and non-potable building services.
Insulated sidewall options where stored-water temperature must remain more stable.
For projects requiring stable water temperatures, FRP tanks can include insulated sidewall panels to reduce heat gain. They are suitable for cooling towers, HVAC and chilled-water systems, make-up and process water, and industrial cold-water storage.
Insulation thicknesses of 25 mm, 40 mm and 50 mm are available based on the project’s thermal requirements.

Since 1 June 2019, only FRP/GRP sectional tanks tested for compliance with SS 245:2014 may be supplied and installed in Singapore for potable water service. It is a regulatory requirement—not an optional quality tier.
The standard covers above-ground tanks of 500 litres and above. Length, breadth and depth follow 0.5 m multiples, with tank depth not exceeding 4 m.
For potable water storage applications, FRP/GRP water tanks should also be maintained according to PUB water tank requirements, including regular cleaning, inspection and certification where applicable.

0.5 m increments, maximum 4 m depth
FRP, GRP and SMC sound confusing? FRP and GRP describe the same tank type; SMC is the panel material.

Sheet moulding compound is hot-pressed into modular panels reinforced with glass fibre. Convex wall panels provide strength, concave floor panels assist drainage, and anti-slip roof panels support safer inspection access.
Panel joints use UV-resistant, food-grade closed-cell sealant. A properly assembled tank is leak-resistant and blocks light penetration, helping prevent algae growth inside potable water storage.
For a simpler introduction to the material and construction, read our guide to how FRP/GRP water tanks are constructed.
Designed to assist drainage and reduce retained residue.
Support safer access during inspection and maintenance.
Food-grade sealing at modular panel joints.
Localised panel damage does not always require full replacement.

Non-insulated panels suit general storage. Standard insulated sidewalls use 25 mm or 50 mm insulation for chilled or expansion water; other builds may be available on request.
The steel skid sits over a reinforced concrete plinth, normally with at least 450 mm support height. The concrete plinth is a separate contractor’s scope.
Typical fittings include a lockable manhole, insect-proof vent, ladders, level indicator and flanged nozzles for inlet, overflow, outlet and drain.
Internal ladders for potable FRP tanks should be FRP or SS316. Aluminium internal ladders are not suitable for potable-water submissions.
Potable tanks require annual cleaning, inspection and certification by the appropriate licensed contractor, with water testing by an accredited laboratory.

Material is not a free choice in Singapore. The application determines it, and specifying the wrong one produces a rejected submission rather than a saving.

A practical sectional tank option that balances initial cost, durability and long-term performance.
Opaque panels and sealed joints prevent light penetration, helping reduce algae growth inside the tank.
Hot-pressed, glass-fibre-reinforced panels provide strength, corrosion resistance and dependable water storage.
Corrosion-resistant panels require no protective metal coating, and individual damaged panels can be replaced.
The tank can be divided into separate compartments to support cleaning and maintenance while retaining water storage.
Modular panels allow the tank to be expanded, reconfigured or relocated where site and design conditions permit.
For a broader overview of why modular tanks are commonly used in commercial and industrial sites, read our guide to the advantages of sectional panel water tanks.
Installation is carried out by our own Singapore crews rather than subcontracted teams, with several installers bringing 10 to 20 years of experience in sectional tank installation and replacement works.
Our in-house installation team delivers safe, efficient works with minimal disruption to your operations.
We specialise in water tank replacement for ageing or leaking systems, ensuring reliable performance and compliance with current standards.
We diagnose and repair tank issues quickly, helping to stop leakage, extend lifespan and avoid unnecessary full replacement.

Our standard warranty for manufacturing defects is two (2) years from the date of tank completion. This may be reviewed and adjusted upon mutual agreement, depending on project requirements.
1 Year DLP
The Defects Liability Period (DLP) for workmanship is one (1) year from the date of completion of installation.
Short answers to the questions most often raised during tank selection and quotation review.
Nothing meaningful. FRP stands for fibre reinforced plastic and GRP for glass reinforced plastic, and in the water tank market the two terms are used interchangeably for the same product. SMC refers to the sheet moulding compound the panels are pressed from.
Yes, provided it is tested for compliance with SS 245:2014. That has been mandatory for potable service in Singapore since 1 June 2019.

4 m. SS 245:2014 caps depth at 4 m, and standard build heights run from 1.0 m to 4.0 m in 0.5 m steps.
Read the FRP Water Tank Sizes, Capacities and Specifications Guide →
Yes. Sectional construction means one panel can be replaced without dismantling the tank, which is often what makes a repair viable instead of a full replacement.

Not for general water storage. Insulation is specified where stored water temperature must stay stable — in practice that means chilled water tanks and expansion tanks. Standard options are 25 mm and 50 mm, and thicker builds including 40 mm can be supplied on request.
