GRP Sewage Tanks manufactured by Eissa Fiberglass LLC are advanced storage solutions designed for the safe collection, storage, and management of wastewater and raw sewage. Manufactured using premium Glass Reinforced Plastic (GRP), these tanks offer unmatched resistance to biological corrosion, hydrogen sulfide (H₂S) gas attack, and aggressive chemicals typically generated in domestic and industrial sewage networks.
A key advantage of GRP sewage tanks is their uncompromising ability to safeguard the surrounding environment. The seamless, non-porous composite construction eliminates micro-fissures and prevents leakage, ensuring wastewater never seeps into the soil or contaminates groundwater tables. For critical projects, tanks can be engineered in double-wall configurations with integrated interstitial leak detection systems.
Every sewage holding tank and septic system is engineered to handle dynamic hydraulic head and aggressive subterranean stresses, configurable with multiple functional internal treatments:
| Feature / Component | Design Details & Operational Benefit |
|---|---|
| Internal Baffle Walls | Integrated multi-chamber GRP baffle partitions for settlement, primary anaerobic digestion, and clarification of solids before discharge. |
| Anti-Corrosion Barrier | Isophthalic / Vinyl ester resin inner contact layer formulated specifically to resist acidic biological slime and volatile sewage gases. |
| Inspection Manways | Reinforced composite manhole chimneys (600 mm to 900 mm clear opening) with odor-tight sealed covers for desludging and maintenance. |
| Ventilation Provisions | Heavy-duty flanged vent nozzles engineered to allow gas relief and prevent hazardous atmospheric vacuum or methane build-up. |
| Ribbed Structural Shell | Circumferential exterior stiffening ribs built to resist high overburden loads, soil compaction, and high water table buoyant uplift. |
Our GRP sewage and effluent tanks are manufactured in standard and customizable capacities to match residential clusters, worker accommodations, and large municipal networks:
Concrete septic and holding tanks crack over time and suffer from microbiologically induced acid corrosion (sulfuric acid created by bacteria digesting H₂S gas). GRP is 100% rust-proof, immune to acidic gas erosion, lightweight for transport, and completely non-porous, ensuring zero groundwater contamination.
Yes. We manufacture multi-chamber septic tanks featuring two or three internal GRP baffle walls with transfer slots, allowing effective solid settlement, oil/grease separation, and clarified water decanting.
Our underground cylindrical tanks feature molded structural ribs and can be fitted with GRP anchor straps and hold-down brackets that tether directly to a concrete ballast slab, preventing flotation in high water table conditions.
Yes. For eco-sensitive coastal sites and municipal conservation zones, we engineer double-wall composite tanks with an interstitial chamber that accepts visual or electronic liquid sensors to immediately signal an internal breach.
