The Flagstaff Hill Golf Club is very aware of the importance of water - it is an essential element in maintaining a golf course, but is a resource that is under pressure. Over time, the club has undertaken a number of initiatives to minimise water use:

  • A Dam for capture and storage of stormwater was built in the early 1980's and later expanded.
  • A computer controlled watering system that delivers precisely controlled quantities of water to the right places, at optimum times, has been installed.
  • Fairways have been replanted with Couch grass, which uses less water.
  • Soil conditioning and fertiliser use is optimised to minimise watering.
  • A Bore is used to supplement stored stormwater in a way that minimises salinity effects.
  • A trial was conducted of an aquifer recharge scheme, however local geology prevented successful operation.
  • Mains water is used only as a last resort, when our own storage is nearly exhausted and salinity prevents further bore water use.

The club liaises regularly with SA Water and conforms to their requirements in relation to restrictions on mains water use.

In May 2007 the club completed a stormwater harvesting scheme, described below.  A summary and explanation of this project is available here.

In 2009 the Club embarked on the expansion of the dam facility, and increased the capacity by 30% by relocating the dam wall closer to Happy Valley Drive. The relocated dam wall is expected to eventually incorporate part of the Onkaparinga Council's walking trail connecting Manning Road to Black Road. The expansion process in documented below.


After many years of planning, design, specifications, approvals, failed grant submissions, more approvals, tenders and submissions, the long awaited expansion of the existing dam facility commenced in February 2009. Kangarilla Earthmovers were given the green light to clear the vegetation and work commenced on 7th February. The vegetation was soon cleared, making a considerable difference to the outlook and perceived size of the area. As we moved into March the earthworks began.

6th March: The Earthworks progressed. The new section of the dam was excavated and work then begun on the removal of the existing dam wall:


Tuesday 12 May: Breaching the old wall

With early rains raising the level of the existing dam,  excavation continued in the new section and the new wall was completed early May. Finally, at 4:39 PM, Tuesday 12th May, the old wall was breached to allow the new area to fill. Click on the image below to watch this fascinating event.

June 2009: The finished product

Late in May it looked like Mother Nature was not going to allow the project to be completed.  However a dry spell towards the end of the month provided a welcome window of opportunity for the contractors to set about removing much of the remaining dam wall and making good the rest of the site.  Although not all of the wall was removed the finished project is great to see and was even better to see full in August 2009.

March 2010

Some remnants of the old dam wall remain through the middle of the new dam and given the right dam levels and weather, the remaining sections will be removed.  This opportunity did not present itself in 2010 due to the timing of Mother Nature, however a window will be sought in 2011 and hopefully another 5 meg of capacity will be gained and the project completed.
