Aquacomb

Aquacomb® is a modular underground water tank designed for both stormwater detention and water reuse. Integrated into slabs, driveways, or under landscaping, it frees up valuable space without compromising on capacity.

Key Features:

- Modular and Customisable: Average installation ranges from 3,000 to 30,000 litres to suit project needs.
- Hidden Integration: Installed within the building’s structure for a clean, unobtrusive look.
- Cost and Time Efficient: Reduces engineering and excavation costs while speeding up installation.

Aquacomb Pod Options

An Aquacomb AquaPit is the one point of entry and exit of water to and from your Aquacomb system. 

All of your downpipes will be brought underground into the AquaPit. 

Re-Use AquaPit

We install a suction feed with a filter which the pump will pull water from to supply toilets/laundry and outdoor taps. This AquaPit also has an overflow for when the tanks are already full.

Detention AquaPit

We install an outlet orifice which restricts the outflow of water down to a much lower speed, this attenuates the water, reducing peak runoff volume to the main stormwater connection. It also has an overflow for when the tanks fill up.

FenceTank

FenceTank™ transforms the conventional water tank into a design feature. With a sleek, slim profile of only 410mm deep, it doubles as a functional fence element—ideal for sites where space and aesthetics are key.

Key Features:

- Aesthetic Integration: Blends into property perimeters with available colour options (Birch Grey, Slate Grey, Black).
- Quick and Easy Installation: Secure mounting without the need for extensive foundations.
- Cost-Effective: Optimises water reuse while reducing water bills by up to 56%.

Approved for use on and within 1 metre of a boundary or building

Residents of a Hobsonville Point subdivision that use the FenceTank system to collect rainwater have saved an average of 56% on their water bills. This represents the same amount of water that they can use for potable purposes, such as washing the car, watering the garden, and flushing toilets.

High Density Developments

Our tanks can withstand 15,000 hours of harsh UV lights, 8,000 hours above what is legally required.

Made with Rotathene Tank Grade plastic which is globally recognised as the most appropriate grade for New Zealand’s harsh conditions and UV light.
 
This grade carries a series of certifications and complies with many international standards within the tank industry. It is designed for potable water or stormwater and is ideal for re-use systems.

SLIM CITY

SLIM CITY Tanks are designed specifically for urban environments. With ultra-slim profiles and available capacities of 2,000L or 3,000L, they offer a compact, efficient solution for rainwater harvesting without compromising on capacity.

Key Features:

- Compact Design: Depths as low as 510mm (2,000L) and 750mm (3,000L) to maintain a low footprint.
- High-Quality Materials: Manufactured in New Zealand using accredited, food-safe, UV-resistant polyethylene.
- Design Flexibility: Available in multiple colours to complement any architectural style and integrated with installation kits.

Unique Slim Design

With flat sides and a slim profile these tanks fit well in any city or suburb where your design requires 2 or 3,000 litres for detention or re-use.

The 2,000l tank is only 510mm deep (should leave room for a bin to pass) or 750mm for the 3,000, so it has a low footprint. 

With its compact design and range of colours it will blend seamlessly into a property without being an eyesore.

Made For NZ Conditions

Made with the highest accredited food-safe polyethylene in NZ at a competitive price.
 
Moulded in one piece and designed to ensure that stresses are contained within the patented ribbed walls and domed construction.
 
Manufactured to the Australian and New Zealand water tank standard AS/NZS 4766:2020 and are independently certified by a professional engineer.
