Fountains? ripple effect keeping lillies at bay
TWO new fountains installed in the Knox Park "duck pond" in central Murwillumbah at a cost of $4000 are expected to keep the once weed-infested water in a much more pristine condition.
Tweed Shire Council environmental health officer Doreen Eaton said yesterday the rippling of the water surface caused by the fountains should discourage the spread of water lillies and duckweed.
In recent years the weeds have had to be harvested regularly at a cost of thousands of dollars.
The submersible electric pumps which power the fountains were turned on last week.
Ms Eaton said the council had already received a number of compliments about the fountains.
She said she was assessing how the two fountains operate before considering installing a third.
"The reason for the fountains is to break up the surface tension of the water so we don't have as much lilly growth and to circulate the water," she said.
The council may also consider installing lights to make the fountains shine at night.
Their installation follows the planting of a variety of reeds near the outlet of the pond which was originally intended as a stormwater collection area.
