Saudi Arabia Customer Project: Customized FRP Covers for Square and Circular Wastewater Tanks
With the increasing demand for environmental protection and industrial wastewater management, reliable tank covering systems have become an important part of wastewater treatment projects. Recently, we successfully completed the production of customized FRP wastewater tank covers for a customer project in Saudi Arabia.
As a professional FRP / GRP manufacturer, we supplied customized pultruded FRP covers and FRP dome covers according to the customer's tank structure and project requirements. The products were completed ahead of schedule, providing an efficient and durable solution for wastewater tank coverage, odor isolation, and corrosion protection.
Customized FRP Covers for Different Tank Shapes
Different wastewater treatment projects have different tank structures. Some tanks are rectangular, while others are circular. Our FRP cover systems can be customized according to various tank shapes and dimensions.
Our solutions include:
Pultruded FRP Covers for square and rectangular tanks
FRP Dome Covers for circular tanks
FRP Arch Covers for large wastewater basins
Customized fiberglass tank covers for industrial applications
Whether it is a square wastewater pool, circular settling tank, chemical tank, or industrial process basin, FRP covers can be designed to achieve effective coverage and protection.

Pultruded FRP Cover System for Wastewater Treatment Plants
The Saudi Arabia project used a pultruded FRP cover structure, which combines FRP structural profiles and cover panels to create a strong and lightweight covering system.
Compared with traditional metal covers, FRP wastewater tank covers provide excellent advantages:

Excellent Corrosion Resistance
Wastewater tanks often contain corrosive gases such as hydrogen sulfide (H₂S), which can accelerate corrosion of steel structures.
FRP covers are resistant to:
Chemical gases
Moisture
Acid and alkali environments
Industrial corrosive conditions
This makes FRP covers an ideal choice for wastewater treatment plants, chemical plants, and environmental projects.
Odor Control and Gas Isolation Solution
One of the main purposes of wastewater tank covers is to control unpleasant odors.
By covering wastewater tanks with FRP odor control covers, the released gases can be collected and transported through duct systems to further treatment equipment.
A complete odor control system can include:
- FRP Tank Covers
- FRP Duct Pipes
- FRP Scrubber Towers
- Biofilters
- Biotrickling Filters
This solution helps improve the working environment and supports environmental protection requirements.
Protection Against Rainwater and External Pollution

In addition to odor control, FRP covers provide effective protection against external factors.
The closed cover structure helps:
Prevent rainwater from entering wastewater tanks
Reduce dilution caused by stormwater
Protect treatment processes
Reduce exposure to outdoor conditions
Especially in areas with heavy rainfall or harsh climates, FRP wastewater covers provide an effective protective barrier.
Lightweight, Strong and Easy Installation
FRP materials offer a unique combination of strength and lightweight properties.
Advantages include:
✔ Lightweight structure
✔ Easy transportation and installation
✔ Long service life
✔ Low maintenance requirements
✔ Customizable size and design
FRP covers are suitable for both new wastewater treatment projects and upgrading existing facilities.
