GRP Sectional
Water Tanks
MED-Bahrain approved modular GRP water tanks for potable, industrial, firefighting and irrigation storage — engineered, laminated, and installed by Zarwan Fiberglass in Al Hamala, Bahrain.
Bolted, modular GRP tanks
built for Bahrain.
Zarwan GRP sectional water tanks are assembled from high-strength glass-reinforced plastic panels, sealed with food-grade gaskets, and bolted into a monolithic, leak-proof structure. The modular design lets us configure any volume — from compact rooftop tanks to million-litre reservoirs — without the heavy civil works or long lead times of concrete alternatives.
Every tank is produced in our Al Hamala facility under ISO 9001:2015 quality procedures and can be supplied with MED-Bahrain approved documentation for Ministry of Works and municipal projects.
Specifications
& sizing
All dimensions and capacities are project-specific. Standard designs are engineered for the GCC climate — high salinity, UV exposure, and seismic loads. We can provide structural calculations, GA drawings, and hydrostatic test reports for consultant approval.
Applications
across every sector
WRAS/food-grade resin options for drinking water and municipal supply.
Cooling water, demineralized water, and process-water storage for plants.
Large-volume agricultural water storage across farms and landscaped developments.
Dedicated fire-water reservoirs and sprinkler make-up tanks.
Balancing tanks, thermal storage, and grey-water systems for commercial towers.
Vinylester resin builds for aggressive water chemistries.
Outperforms steel
and concrete.
Unlike steel tanks, GRP sectional tanks do not corrode, require no repainting, and are safe for potable water. Unlike concrete tanks, they are lightweight, leak-tight, and can be installed in days rather than weeks — with minimal foundation requirements.
GRP panels will not rust, rot, or scale — even in Bahrain's coastal atmosphere.
Bolted panels ship flat and assemble on-site to any footprint or height.
