Underground Water Tanks from KHD Landscape Engineering

Underground Water Tanks for Sustainable and Smart Projects
KHD is a long supporter of sustainable projects and in recent years have worked with a number of Architects specifying Underground Water Tanks for interesting and innovative outcomes.
Of note was the Meadows Primary School designed by NOWArchitecture.
The school now enjoys a passive hydrothermal air conditioning where the high raking ceilings allow hot air to rise above activity spaces and exit through upper louvre windows, providing excellent thermal comfort and air quality.
Thermal buoyancy expels hot, stale air and pulls fresh air, which has been cooled by the sub-floor VersiTank water tanks (supplied by KHD), in through floor grilles.
The project won Best New School in Victoria from the Council of Education Facilities Planners International.
VersiTank is a heavy duty plastic tank that allows either sub-surface infiltration or storage tank of stormwater.


VersiTank stormwater tanks provide an efficient at-source management system for rainwater from roofs and other impermeable surfaces such as parking areas, driveways, playgrounds and sports fields.
VersiTank stormwater tanks are available in several sizes and load-bearing capacities cater for the requirement of individual houses up to the largest commercial and industrial developments. Of note is the large Port Pirie project in South Australia.
VersiTank modules are easily assembled on site by clipping together lightweight, high strength interlocking panels. Assembled units can be interlocked both vertically and horizontally thereby ensuring the system remains stable under trafficable or high weight bearing load areas.
KHD also supplied a 47,000 L VersiTank, Bionic Tiles and Australian Bluestone for the Bairnsdale Library and Community Hub Project also designed by NOWarchitecture.
The VersiTank provides water for the toilets and irrigation system but is also used to significantly reduce the running costs of the air conditioning systems. Large diameter plastic pipes were buried beneath the VersiTank to allow tempered fresh air to securely enter the Library at a low level as part of the passive cooling and ventilation system.
