Design Innovation

Government & Industry Bodies regularly consult with Aquatec for guidance on best practice product development & safety standards.

Filament Wound Construction
Aquatec's Storage Vessels are constructed using a state-of-the-art computerised winder and manufactured with the highest-grade resilient resins and rovings to achieve benchmark standards of quality and integrity.

One-piece Chamber
The Storage Vessel cylinder and end caps are mould formed as one piece to strengthen the overall structure. Unlike precast concrete alternatives, horizontal pipes, man-hole risers and end caps are glassed in a factory environment providing an impervious, holistic structure.

Advanced Ribbed Construction
Aquatec’s Advanced Ribbed Construction achieves the equivalent strength of Traditional Flat Construction with less materials at a reduced cost while minimising our environmental footprint.

Installation Process

Aquatec’s Storage Vessels arrive on-site as one-piece for immediate installation, supported by WHS compliant installation manuals & on-site delivery supervision.

Inlet, overflow, vent and conduit penetrations are pre-glassed for easy on-site connections. To overcome buoyancy, Aquatec’s engineers consider weight requirements, water table proximity and ground conditions to identify a Concrete Ballast or Deadman Anchor installation method.

Quality Auditing & Installation Management
Aquatec’s qualified On-Site Supervisors are committed to overseeing the installation of your Storage Vessel, providing product knowledge and on-site support to ensure best practice installation. Following installation, Aquatec’s auditors will carry out a thorough check of the product to ensure no damage has occurred during the installation process in preparation for final testing and commissioning.

    Structural Design

    Aquatec engineers the structural design of every Storage Vessel for optimum performance during projected peak in-flows and ground conditions on-site.

    Geotechnical reports establish the strength required to withstand ground pressure, excavation depth, location and trafficable loading, water table proximity and soil type.

    Product Integrity

    For the past 30 years, Aquatec's commitment to product integrity has remained central to our daily operations.

    Manufacturing Process

    Aquatec's Storage Vessels are manufactured in a controlled factory environment under strict ISO 9001: 2008 standards.

    Unlike cast in-situ Storage Vessels, our product quality is not subject to weather, site conditions and associated time delays.

    Quality Control

    Aquatec’s manufacturing process is subject to a series of strict quality control measures to achieve superior product quality:

    • Controlled factory conditions
    • Computerised winders for controlled wall thickness
    • Strength testing
    • Checklists / hold points
    • Third party engineer certificates
    • Transportation

    Environmental Benefits

    Storage Vessels safeguard the environment against the risk of effluent overflow & environmental damage.

    The Eco Choice

    Every Storage Vessel is designed and sized to handle inflows based on WSAA, Water Authority or Council requirements in emergency situations. Aquatec's ability to deliver our product to site as a one-piece unit reduces excavation periods and secures minimal disruption to flora and fauna.

    Guaranteed Seal Integrity

    Aquatec’s Storage Vessels are manufactured as a completely sealed, one-piece vessel. All penetrations and wall fixings to the structure are carried out in the factory with compatible materials, allowing no chance of ingress or egress.

    Safety Features

    Aquatec incorporates advanced safety features into the design of every Storage Vessel for the safety of installation & maintenance personnel, setting new standards in safety & serviceability.

    Light Weight Chamber
    Unlike concrete precast alternatives, Aquatec’s Fibreglass Storage Vessels are lightweight and arrive ready to install with WHS approved installation instructions. Supported by on-site delivery and supervision, workplace hazards are drastically reduced.

    Access Covers
    Available in 316 stainless steel, aluminium, galvanised or cast iron, Aquatec’s access covers are also available in a range of sizes to suit your application.

    Reduced Excavation Periods

    Site excavations are often left unnecessarily exposed for long periods of time, presenting serious safety risks for installation personnel.

    Reduced Excavation Periods
    Aquatec’s one-piece designs decrease installation time, reducing the excavation period required during installation.

    Optional Safety Accessories

    Access Ladders & Landings
    Available in 316 stainless steel, galvanised, powder coated, or fibreglass, Aquatec’s Access Ladders and Landings can be incorporated into product designs where internal well access is required.

    Our Technical Consultants can advise on landing depths and sizes in accordance with WHS safety requirements. Aquatec’s Ladders can be manufactured with non-slip knurled rungs for added safety protection.

    Aquatec’s range of permanent or portable Handrails offer additional safety protection for maintenance personnel in accordance with AS 1657-1992 or Water Authority requirements. Available in stainless steel, galvanised steel, powder coated or aluminium.

    Safety Grates
    For pits that exceed two metres, an optional safety grate can be supplied. Aquatec’s Safety Grates can be installed underneath Access Covers to provide an additional lay flat, fall arrest safety mechanism for maintenance personnel.
