Managing a Salty Environment
Lengthy dredging of the adjacent enormous lakes and lagoon produced enough fill to raise the entire course area to a safe height above sea level. 4 million cubic meters of dune sand from the adjacent desert was brought in and evenly spread over the fill to a depth of 30cm as the growing medium.
The intention was to irrigate the course by “Treated Sewage Effluent” to be generated from the existing hotel and the new 1200 hotel rooms and 950 residential dwelling units. However until such times the new hotel rooms and residential units were occupied there would be no treated effluent water available. To satisfy this period Techno-Green Corp was requested by the course designer Peter Harradine, to submit a proposal for the irrigation requirement during establishment and maintenance of the grass and landscaping
with the use of their water conservation product "AQUA-FEED" in the soil profile.
The Challenge
With acceptance of this proposal by the course designer and resort developer, a desalination barge was chartered to supply the initial irrigation water requirement.
A further problem that was of concern to the designer was the closeness of the course to the sea, where airborne and high water table salt contamination could affect the vegetation. The Gulf water is very saline at 44000ppm. Techno-Green’s - Nature’sBio® Organic Soil Amendment was selected to control and minimise this concern.
Holes 1,2,3,4,5,6,7,17,and 18 the driving range and academy course were opened during April 2007 with the remainder of the Par 72 Championship Course scheduled for opening late 2007 –early 2008.
The total irrigation usage is 4000 cubic meters per day average, being approximately 35% less than a similar course without a water conservation product in the soil profile.
This saving is permanent as
AQUA-FEED does not deteriorate over time, nor is it affected by the presence of salt.
