Green Cities provides a complete stormwater harvesting solution. We offer stormwater filtration, water storage, integrated irrigation system and the purification of stormwater.
This solution replaces antiquated Roman technology. Pipes, sumps, pits or difficult to manage gross pollutant traps, are no longer required to manage stormwater. These are replaced by underground water tanks, restoring the balance between the environment and urban development.
The Infiltration Tank System is the ideal way to manage stormwater runoff in permeable or semi-permeable soil conditions. The system is designed to capture surface water through infiltration, and then clean and filter the water before it is allowed to recharge the water table providing moisture for surrounding vegetation.
How It Works
The system is designed to capture surface water through infiltration, and then clean and filter the water before it is allowed to recharge the water table providing moisture for surrounding vegetation. The Filtration Unit also captures and cleans roof water before entry into the storage area (Flo Tank Modules).
The Detention System is a cost effective solution that can also address water quality. The system offers flexible design options, saving installation time and delays to site access.
How It Works
Water captured from roof and paved areas are filtered through an Atlantis Filtration Unit before entering the storage area (Flo Tank Modules). Water is then slowly released through the discharge control unit (DCU).
Water Sensitive Urban Design
We provide many different solutions for housing developments to cater for low impact development and water recycling solutions for various environmental conditions. Green Cities' solutions enable the maximum use of land for developers whilst meeting low impact development criteria.
Three times more efficient than traditional leach drains. The Leach Drain System was designed to replace gravel and pipe leach systems. It is faster to install and more reliable than traditional gravel systems.
The Leach System is a modular system of polypropylene tanks connected in a series. The lightweight tanks are assembled on site and easily positioned in the trench and clipped together. The effluent pipe is connected prior to the drain being covered on top, sides and ends with Hydronet woven geotextile.
After backfilling with clean sand, the drain is ready for use.
The Channel System provides permanent underground waterways that restores water quality and recharges the natural environment. The underground channel system provides a unique way of working with nature to solve the enormous problems currently associated with open concrete channels.
With the channel system being an underground system, these problems with open concrete channels are rectified. The permeable channel system can be designed to follow inherent contours of the landform and emulate the flow of natural waterways. This channel design creates vertical flow turbulence and reduces the overall flow velocity while increasing the self-cleansing capacity of the channel bed to create healthy aerobic conditions.
Traditional Concrete Channels
Open concrete channels are currently one of the main methods of transporting large quantities of stormwater for discharge into creeks, rivers and oceans. Open channels are used widely in the urban landscape even though they are considered unsafe. Channels are also a breeding ground for vermin and vector that endanger human health. In addition to the health and safety problem, large concrete channels take up vast areas of land and have a negative impact on the amenity of the area.
