What is a GRP Septic Tank?

A septic tank is an underground wastewater treatment system that collects and partially treats sewage from a property through a process of physical settlement and natural biological action. In UAE, septic tanks are the approved solution for on-site wastewater management wherever mains sewage connection is unavailable - residential villas, farms, remote desert sites, labour camps, and construction sites.

Khazzan's septic tanks are manufactured from GRP (Glass Reinforced Plastic) - also known as fibreglass. GRP is the preferred material for UAE septic tanks because it is completely resistant to the corrosive hydrogen sulphide gas produced in sewage environments, unlike concrete which corrodes and fails within 5–15 years. GRP is also watertight by construction - preventing sewage seeping into surrounding soil and groundwater contamination into the tank.

We supply both single-chamber (primary settlement) and two-chamber (primary + secondary treatment) configurations, sized for everything from a 2-person studio to a 500-person labour camp.

Single-Chamber Septic Tank

One compartment handles primary settlement. Solids sink to the bottom (sludge), fats float to the top (scum), and clarified effluent exits through the outlet. Suitable for residential applications with regular desludging service.

300 USG – 5,000 USG

Two-Chamber Septic Tank

Primary chamber for initial settlement, second chamber for further clarification. Produces cleaner effluent - recommended for larger installations, soakaway discharge, or where municipality requires better treatment quality.

1,000 USG – 20,000 USG

Benefits of GRP Septic Tanks

Underground-Rated Construction

GRP septic tanks are engineered for below-ground installation, with reinforced wall construction designed to withstand soil overburden pressure and groundwater buoyancy in UAE ground conditions.

Completely Watertight

GRP construction is inherently watertight - no seepage of sewage into surrounding soil, no groundwater infiltration into the tank. Prevents contamination of soil and groundwater.

Hydrogen Sulphide Resistant

The anaerobic sewage environment produces corrosive hydrogen sulphide gas. GRP's chemical-resistant inner lining handles this environment without degradation - unlike concrete, which corrodes rapidly.

No Odour Leakage

Watertight sealed construction with odour-sealed access covers prevents sewage gases from escaping into the surrounding area - critical for residential and commercial installations near occupied spaces.

Single and Two-Chamber Options

Single-chamber tanks provide primary settlement and storage. Two-chamber tanks provide primary and secondary treatment - better effluent quality for discharge or soakaway applications.

Lightweight vs Concrete

GRP septic tanks are significantly lighter than concrete alternatives, making delivery and installation simpler. No crane typically required for residential sizes - reduces installation cost and complexity.

Long Service Life

GRP does not rust, corrode, or biodegrade. Unlike concrete, it does not crack under freeze-thaw cycles, does not absorb water, and does not require waterproof coating treatments.

Fast Installation

Factory-manufactured to finished specification - delivered ready to install. No on-site concrete pouring, curing time, or specialist construction required. Installation can typically be completed in one day for residential sizes.

UAE Municipality Compliant

All Khazzan GRP septic tanks are compliant with UAE Municipality requirements for on-site wastewater treatment systems across all seven emirates.

Suitable for Remote Sites

Where mains sewage connection is unavailable - desert sites, farms, labour camps, temporary installations - GRP septic tanks provide an immediate, self-contained wastewater solution.

Custom Sizes Available

For large industrial, infrastructure, or multi-building applications, custom-manufactured GRP septic tanks can be fabricated to project-specific capacity and configuration requirements.

Accessible for Maintenance

Standard access manholes and inspection ports on all sizes allow for desludging, inspection, and maintenance without excavating or removing the tank.

Applications

GRP septic tanks are used across all sectors in UAE wherever mains sewage is unavailable:

Residential Villas
Apartment Buildings
Labour Camps
Staff Accommodation
Restaurants & Cafés
Retail Outlets
Commercial Offices
Schools & Nurseries
Construction Sites
Remote Desert Sites
Farms & Agricultural Land
Industrial Facilities
Service Stations
Mosques
Temporary Event Sites
