Installation Best Practices for GRP Tanks: A Complete Guide

GRP (Glass Reinforced Plastic) water tanks are increasingly becoming the go-to solution for large-scale, hygienic, and durable water storage across East Africa. However, even the highest-quality tank panels can underperform or fail prematurely if not installed correctly. Proper installation is key to ensuring long-term safety, efficiency, and durability.

At Aquosys Limited, we don’t just supply GRP sectional tanks—we also provide professional installation services that comply with international standards. This guide walks you through the best practices every engineer, contractor, and project manager should follow when installing a GRP tank.

Why Proper Installation Matters

A correctly installed GRP water tank offers:

• Structural Integrity – Prevents panel deformation or leakage.

• Hygiene – Ensures water remains clean and safe for consumption.

• Longevity – Extends tank lifespan, reducing maintenance costs.

• Compliance – Meets regulatory and engineering standards.

Discover how our Installation Services ensure every project is executed to perfection.

Pre-Installation Considerations

Before tank assembly begins, project teams must carefully evaluate:

1. Site Assessment

• Check for accessibility of trucks and lifting equipment.

• Evaluate soil bearing capacity for ground tanks.

• Confirm structural strength for rooftop installations.

2. Foundation Requirements

A solid, level foundation is crucial for stability. Options include:

• Reinforced concrete bases.

• Steel frames for elevated or rooftop installations.

Refer to our Reinforcement guidelines for large-capacity tanks.

3. Tank Design and Partitioning

The tank must be designed to fit the site while accommodating the required capacity. Our Partition Types allow flexible designs for basements, rooftops, or ground-level installations.

Best Practices During Installation

1. Proper Panel Handling

• GRP panels should be lifted with care to avoid cracking.

• Avoid dragging panels on rough surfaces.

• Store panels in a shaded, dry area before assembly.

2. Bolting and Sealing

• Use stainless steel bolts to prevent corrosion.

• Apply approved sealing materials between panels to ensure watertight joints.

• Tighten bolts systematically to maintain even pressure distribution.

3. Reinforcement and Bracing

• Install internal braces for larger tanks to prevent panel bulging.

• For high-capacity tanks, consider external reinforcement.

• Follow engineering specifications for safe pressure resistance.

Check our Caution guidelines for common installation mistakes to avoid.

4. Insulation and Protection

For sites prone to extreme heat or cold, additional Insulation solutions are recommended to maintain water temperature stability.

5. Inlet, Outlet & Overflow Connections

• Position inlets to minimize turbulence.

• Ensure outlets are properly aligned to avoid leakage.

• Install overflow pipes with mosquito-proof mesh for hygiene.

6. Hydrostatic Testing

Before commissioning, tanks should be filled with water for leakage and load testing.

• Fill gradually, checking for leaks at each stage.

• Confirm structural stability under full load.

Post-Installation Maintenance Best Practices

Even with proper installation, routine checks are necessary:

• Inspect bolts and joints regularly.

• Clean tanks periodically to maintain hygiene.

• Re-seal joints if any signs of leakage appear.

Common Mistakes to Avoid

1. Installing tanks on uneven or weak foundations.

2. Using low-grade sealing materials that compromise hygiene.

3. Ignoring reinforcement requirements for large capacities.

4. Over-tightening bolts, causing panel cracks.

5. Skipping hydrostatic testing before handover.
