FIBREGLASS . . . UNDERGROUND WASTEWATER TANKS 

PEACE OF MIND . . . IS OUR PROMISE TO YOU

CONCRETE IS DEAD ... LONG LIVE FIBREGLASS

FINALLY ... a Cost-Effective ALTERNATIVE to CONCRETE  for the SAFE CONTAINMENT of WASTEWATER.

Today's designs for Decentralized Wastewater Treatment Systems are becoming Increasingly Sophisticated and also Dependent on Large Capacity Water-Tight Storage and Process Tanks.

INFILTRATION from a Leaking tank can result in an ... Improperly Functioning system, while Infiltration causes POLLUTION of Water Supplies.

GREENTANK Fibreglass Tanks are the PERFECT ALTERNATIVE to  Pre-Cast or Pour-In-Place Concrete Tanks.

ADVANTAGES

  • WATERTIGHT DESIGN - with the option to field pressure test before and after installation
  • LARGE CAPACITIES - available in one-piece factory manufactured sizes from 2,500 to 150,000 litres.
  • QUICK and EASY INSTALLATION - Installed and backfilled in a day or two versus weeks of site construction for a pour in place concrete tank.

WATERTIGHT TANKS FEATURING THE MANY BENEFITS OF FIBREGLASS

A GREENTANK Fibreglass Wastewater Tank, by virtue of its Materials and Design, is inherently the SUPERIOR CHOICE for SAFE, Long-Term Storage and Treatment of Wastewater for a Wide Range of Applications.

The BEST storage system for Wastewater is Structurally Strong,Corrosion-Resistant, Watertight, Easily Installed and Cost-Effective.

All these elements come together in the Design and Manufacture of a GREENTANK Fibreglass Wastewater Tank.

GREENTANK uses only High-Quality Resin and Glass in the manufacture of its Fibreglass Tanks.

For added Structural Strength ... GREENTANK Fibreglass Tanks are designed with Integral Ribs.

Because the Integral Ribs and tank are made of the same materials and are manufactured simultaneously, the GREENTANK Fibreglass Tank is a very Robust Tank.

It is Designed to Accommodate ... Heavy Traffic Loads and HighWater-Table Conditions when properly installed.

Fibreglass tanks available from smaller fabricators may also utilize ribs, but they may not be designed for traffic environments and do not have the same robust design features of a GREENTANK tank.

While CONCRETE Tanks are widely viewed as Structurally Strong ... many are NOT designed for the heavy loading conditions that vehicle traffic and groundwater can present.

Since Water by nature Can Create a Corrosive Environment, RUST can be a major weakness in some underground wastewater storage systems.

The Materials used to Construct GREENTANK Fibreglass Tanks are inherently RUST-PROOF and CORROSION-RESISTANT.

Concrete tanks, whether Precast or Poured-In-Place, are Susceptible to Rust if the steel reinforcement is exposed through Cracks in the concrete.

Exposure to Hydrogen Sulphide Gases, present in wastewater tanks, can also cause Corrosion Damage to a Concrete Tank and Steel Reinforcement ... thereby Limiting the Tank's Useful Life.

Since Wastewater Tanks can be exposed to highly corrosive conditions, selecting a GREENTANK Wastewater Tank gives system owners and designers the assurance that rust or corrosion will not cause a leak or structural failure.

Aside from being Rustproof and Corrosion-Resistant, a GREENTANK Fibreglass Tank is also designed to be WATERTIGHT.

Easily equipped for on-site pressure testing before or after installation, GREENTANK Wastewater Tanks give owners the Confidence that the Tank is WATERTIGHT from the day it is installed.

This feature is of growing importance with today's stringent regulations, many requiring watertight systems.

LEAKING CONCRETE TANKS ... are one of the reasons that GREENTANK Fibreglass Tanks have become such a Popular Choice for Wastewater Applications.

Concrete, by its nature ... is Vulnerable to Cracking. In most cases, Precast Concrete Tanks rely on sealants or adhesives to seal the seams designed into the tank.

When the ground around the tank shifts or settles, or when the tank is improperly installed, these seams are Susceptible to Leaking, causing either groundwater contamination or groundwater infiltrating into the tank, requiring the system to processes groundwater along with septage.

A Structurally Strong, Watertight Fibreglass Tank ... Eliminates both of these problems.

Quality manufacturing is key to producing a Strong, Watertight Tank.

When it comes to the environment, GREENTANK knows that too much is at stake to manufacture anything less than a SUPERIOR Underground Storage Tank.

GREENTANK maintains High Standards of Quality in the manufacture of each tank. The quality control steps are applied in a tightly controlled manufacturing environment.

On the other hand, the same level of quality control may not be maintained in situations where tanks are assembled, in part or in whole, in the field and where weather conditions may not allow careful quality control procedures.
