Water tank selection is often left to the last stage of a project and compared only on price per ton. In reality, GRP water tank price depends on many technical variables, from capacity and panel thickness to certification and installation conditions. This guide summarises what to check when you request a quotation.
1. Capacity and dimensions
Sectional GRP tanks are built from standard panels, so the first price driver is the net volume (m³) and the length × width × height combination that delivers it. A taller tank uses fewer base panels but needs panels and supports rated for higher pressure.
2. Panel thickness and height
Lower panel rows carry higher hydrostatic pressure, so thicker panels are used as height increases. Ekomaxi panels are pressure-tested at up to 4 times their working pressure. Always ask which thickness is used on each row.
3. Potable water approval (WRAS, TS EN 13280)
For drinking water, independent proof that the panel material does not affect water quality is essential. WRAS is the most requested approval internationally. Ekomaxi is the first Turkish manufacturer with WRAS approval up to 50 °C for composite panels.
4. Bracing and support system
Internal tie rods and external supports may be hot-dip galvanised or stainless steel, depending on the environment (indoor, outdoor, coastal, chemical) and the stored water.
5. Insulation and climate
Insulated panels prevent freezing in cold climates and overheating where temperatures reach +50 °C, as in the Gulf, Iraq and North Africa.
6. Accessories and connections
Manholes, ladders, vents, level indicators, overflow and drain lines, flanged nozzles and partition walls change the scope of the offer — make sure you compare like with like.
7. Freight, installation and site
Shipped knocked-down, GRP tanks have low freight costs, but distance, site access and location (roof, basement, ground) still matter, as does who provides the concrete plinth or steel skid.
Look at total cost, not just the first price
Concrete tanks take weeks to build and may crack and leak over time. GRP sectional tanks are installed in days, can be expanded or relocated and offer a minimum 50-year economic life.
Ekomaxi exports GRP sectional water tanks to more than 60 countries. Contact us for project-specific sizing and a quotation.
