Advantages for Your Industrial Wastewater Treatment Plant
Our 5000L FRP sewage tank is engineered to reduce downtime and lower total cost of ownership. The corrosion-resistant nature eliminates the need for frequent painting or lining replacement common with steel tanks. Its lightweight design allows for easy handling during installation, even in confined spaces. The 3/4-inch inlet and outlet are perfectly sized for moderate flow rates, and the tank can be paired with pumps, filters, or mixing systems. Additionally, the smooth interior surface minimizes resistance to flow, enhancing treatment efficiency. For plants requiring multiple tanks in series, we offer consistent dimensions and connection compatibility for seamless integration.
Customer benefits:
- Extended service life of 20+ years under normal operating conditions.
- Reduced maintenance costs – no rust, no chemical attack.
- Quick installation – no heavy equipment needed for positioning.
- Customizable accessories – inlet/outlet orientation, extra nozzles, manholes.

Frequently Asked Questions (FAQ)
-
Q: Can this tank be used for underground installation?
A: Yes, the FRP tank is designed for both above-ground and underground applications. However, for underground use, we recommend adding a concrete anchor or using a heavier wall thickness to resist buoyancy. Please consult our engineering team for specific recommendations. -
Q: What is the maximum working pressure?
A: The standard tank is designed for atmospheric pressure. For low-pressure applications (up to 0.5 bar), we can reinforce the walls and add appropriate fittings. Custom pressure ratings are available upon request. -
Q: Can I get a different inlet/outlet size?
A: Absolutely. While the standard configuration is 3/4 inch NPT, we can customize the connection size to 1 inch, 2 inches, or flanged connections. Please specify your requirements. -
Q: Are there any certifications for this tank?
A: Our products are manufactured under ISO9001:2015 and ISO9000 quality management systems. Specific certifications for drinking water or food contact can be provided if required, but for sewage applications, the standard corrosion resistance is sufficient. -
Q: What is the typical lead time for this tank?
A: For standard models, the lead time is 15–25 working days. Custom orders may take longer depending on the complexity. We can expedite sample orders for urgent projects. -
Q: How do I clean the tank?
A: The smooth interior surface makes cleaning straightforward. You can flush with water, use mild detergents, or employ a tank cleaning nozzle. Avoid abrasive tools that may scratch the gel coat. -
Q: Do you offer installation services?
A: We do not provide on-site installation, but we offer detailed installation manuals and technical support. For large projects, we can recommend local partners. -
Q: What warranty do you provide?
A: We offer a 2-year warranty against manufacturing defects. Extended warranties are negotiable for bulk orders.
