Made For Concrete Slabs

Not Your Usual Water Tank

The Aquacomb water storage system is a series of interconnecting polyethylene water tanks or ‘pods’ that are positioned inside a concrete slab to capture, store and either re-use or release rain water.

The system is designed to manage rainwater (OSR) and stormwater (OSD) for residential, industrial and commercial properties.

Key Design Principles

The four key principles for designing an Aquacomb® system are:

  1. Aquacomb® is incorporated into a concrete slab as a non-structural, void former element.
  2. To allow water to enter the system, an atmospheric vent must be installed.
  3. The location of the Aquacomb® pods within the concrete slab requires a clear area where penetrations for services are not present i.e. bathrooms, laundries and kitchen sinks.
  4. A pump provides water services to the property from the Aquacomb®.

Design On-Site Retention (OSR)

On-Site Retention System Design (OSR)
The term “retention” is used to describe the capture, storage and reuse of clean rainwater. Generally the water is used for washing machines, flushing toilets and also provide water to outside taps for cleaning and gardening.

There are three main considerations when designing an Aquacomb® retention system.

  1. Soil type or category classification that determines the slab thickness and therefore the pod depth.
  2. The total volume of stored water that is required by councils, water authorities or DA calculations such as SMAF (Stormwater Management Areas: Flow) etc.
  3. The position of the system within the concrete slab.
