Every project has unique water storage requirements. So, standard GRP tank sizes may not always fit site conditions, capacity demands, or regulatory specifications. Custom GRP Water Tank Size offer complete design flexibility, ensuring optimal performance, space utilization, and long-term reliability.
GRP water tanks in UAE are customized to meet project-specific requirements such as capacity, layout, installation location, and operational use. These tanks are manufactured using high-grade Glass Reinforced Plastic (GRP) and can be configured in various shapes, sizes, and compartment arrangements.
Custom solutions are ideal when standard sectional tanks cannot meet space, capacity, or design constraints.
At Colex GRP Tanks Trading LLC, we specialize in designing and supplying custom GRP water tanks in UAE tailored to residential, commercial, and industrial applications.
Each tank is engineered to match exact project requirements, including footprint, height, and compartmentalization.
Custom designs maximize available space, making them ideal for rooftops, basements, and restricted areas.
Custom tanks can be designed with separate compartments for: Potable water, Fire fighting water, Process or utility water.
Tanks can be designed to allow future expansion or additional compartments as project needs grow.
Manufactured using premium GRP materials, custom tanks offer excellent resistance to corrosion, chemicals, and harsh UAE weather conditions.
Colex offers extensive customization options to ensure your tank meets all technical and operational requirements.
Available options include:
Recommended for outdoor installations to maintain water quality and reduce temperature rise in the UAE climate.
Suitable for indoor installations such as basements and pump rooms where temperature control is less critical.
One water tank is a limited space creates an effect of installing multiple tanks, which is an economical alternative and efficient for maintenance. Performance Maximize volume in a limited space: The partitioned water tank can maximize the tank volume compared to installing separate water tanks, especially for limited spaces, such as a basement or small areas. Precautions when cleaning: One of tank must maintain less than 50% of the water level for safety when cleaning the other tank. Easy Maintenance: Two tanks are installed as one, which enables easy maintenance and does not require a water supply cutoff for cleaning. Economical: The partition water tank is more cost-effective, including the cost for labor work, and installing separate tanks for different purposes. Various Stage : When a partition is applied, one tank can be utilized as a potable water tank, and the other for utility water (for fire hydrant).
