Sport & Recreation
The Atlantis
Sports field Drainage System is a unique stormwater infiltration
and management system that allows play to continue even under
prolonged wet weather conditions, while providing a solution for
the treatment and purification of stormwater run-off from the
field and surrounding sub catchment areas.
The system greatly reduces stormwater pollution, stops gross
pollutants from being conveyed off-site and can provide a
stormwater re-use system for irrigation of the playing surface
and other field areas.
The system can be designed to provide instantaneous drainage
without drying out the playing surface. The Atlantis Sports
Field Drainage System ensures an optimum playing surface is
maintained by creating an artificial aquifer consisting of the
Atlantis Ecological Drainage Cell blanket style of drainage
beneath.
In combination with the efficient porosity of Atlantis EcoSoils,
excess water can efficiently flow vertically and then
horizontally, well under the playing surface. The result is the
elimination of water logging, erosion and soil deterioration.
The unique design of the Atlantis Drainage System creates a
constant sub-surface aerobic water table in suspension known as
a perched water table.
In dry weather a consistent water supply is maintained below the
surface. Even in a heavy storm the perch remains at a constant
level below the surface. The continual water supply and
beneficial sub soil ventilation of the Atlantis Sports Field
Drainage System results in excellent turf colour, a healthy root
system and stronger more resilient turf overall. The Atlantis
Sports field Drainage Systems facilitates quicker wear recovery
and maintains healthier turf all year by combining a high-growth
root zone environment with rapid drainage rates and increased
moisture retention.
The combination of ReFlex mesh elements developed by Tensar
International and the Atlantis Drainage Cell System in the soil
profile provides the load-bearing capacity of a secondary
bitumen road prevents compaction and sustains root zone
aeration. The profile can be installed on either a consolidated
clay or concrete base. This unique system has been extensively
researched and certified by several universities over the past
15 years.

Atlantis Ecological Golf Course System
Traditional
System:
Two typical methods of golf
course construction are the Texas USGA method and the
Cambridge sports field system. The Texas USGA method
employs a number of horizontal layers of graded
aggregate laid over a sub-grade. Drainage pipes are laid
in the sub-grade and back-filled with aggregate.
Topsoils are placed over the aggregate layers with a
specific root-zone mix placed prior to placement of
turf. Drainage is reasonably efficient, but total
topsoil depths of 400 -500 mm must be constructed to
provide adequate drainage layers.
The Cambridge method involves the use of permeable sand
trenches cut into the topsoil and sub-soil that drain to
equally spaced drainage pipes laid under a drainage bed
of aggregate.
These are supplemented with the use of highly permeable
topsoils often with limited growing capacity. Vertical
drainage is reasonably efficient. Horizontal drainage,
however, is poor as the system relies upon lateral
movement of water for capture.
Water does not flow laterally within a soil to any great
extent. It generally travels downward vertically and
therefore a horizontal drainage system that can capture
all infiltrated water and transport it laterally to
other areas will provide the most effective removal of
water from the playing surface. The USGA method is such
a system, however the large aggregate volume required to
provide sufficient drainage makes such a system very
costly to construct.
Atlantis
System:
If it was possible to replace the aggregate drainage
layers with another material providing the same drainage
capability (at a vastly reduced volume), it would be
possible to build a golf course on as little as 250 -300
mm of imported soil. The Atlantis Drainage Cell System
can provide just that. A cellular drainage product
designed specifically for sub-surface drainage
applications, it has a surface void space of more than
60%, and a void volume of more than 85%. Consider this
in comparison to aggregate, which provides about 40% of
its total volume as void space for drainage and water
retention.
The successful Atlantis Ecological Golf Course System
provides golf courses with a sustainable, efficient and
low maintenance drainage system that maintains playing
surface quality of the while managing potential
environmental impacts. Because traditional drainage
practices don’t provide an ecologically sustainable
method of water management golf courses are coming under
scrutiny by regulatory authorities due to environmental
impacts such as nutrient run-off. Traditional methods of
drainage only add to the exponential degradation of
water quality. To preserve water quality and replenish
groundwater resources infiltration principles must be
utilised.
The natural principles of drainage inherent in the
Atlantis Ecological Golf Course System allows water to
immediately infiltrate the ground, eliminating surface
run-off and erosion. Initially, a golf course inevitably
requires a large tract of land to be almost entirely
cleared of vegetation and topsoil, allowing course
construction, earth moving and landscaping. Golf course
construction process, subsequent turf and grounds
maintenance programs significantly increase the
potential impact upon waterway pollution.
Damage caused during construction is
somewhat alleviated with new landscaping, however damage
caused to subsoil layers ultimately limits the
infiltration capacity of the entire golf course. To
achieve a reversal of the environmental damage it is
necessary to account for lost infiltration and reduced
groundwater recharge. Infiltration is the process of
rainfall soaking into the ground under natural
conditions. Efficient infiltration depends greatly on
soils, ambient flora conditions and the land-use
associated with the area. The Atlantis Ecological Golf
Course System’s artificially recreates the natural
hydrological infiltration processes.

Technical Information

Technical Information :
The Atlantis
Ecological Golf Course System is
constructed of highly permeable drainage
systems that encourage instantaneous
infiltration of rainfall through the
playing surface, efficiently removes
excess sub-soil water to recharge
groundwater or transfers collected water
to other storage areas for reuse.
The Atlantis Drainage Cell System is a
sub-surface system of cellular,
horizontal drainage layers and permeable
under-drains. Separated from topsoils by
a hydrophilic Geotextile, the Atlantis
Drainage Cell system recreates natural
drainage processes in the form of
artificial aquifers (groundwater
bodies). The natural hydrology
principles inherent in the Atlantis
Drainage Cell System successfully
recreate natural conditions to achieve
successful drainage in golf-course
environment. The result is maintenance
of consistent playing conditions and the
preservation of water quality and the
environment. |
