NOTE: NCPA is considering installing CIMS on a large proportion of the 100 hectares of National Areas.
Due to the high cost of installing CIMS, many other irrigated areas were not linked to the system, as the gains would have been minimal. However, some of these facilities use manual systems which are programmed using the information supplied by the CIMS system, and therefore some water savings are achieved..
(3) All the CIMS sites have rain sensors These are programmed to cease watering after 1mm of rain has fallen, arid watering is delayed to prevent watering in the rain.
Most other sites do not have rain sensors installed a$ yet, however, recent improvements in rain sensor technology are currently being evaluated. Previously available units have proven to be unreliable, vandal prone, and expensive to maintain.
It should be pointed out that watering by these systems during rain would only represent less than 0.5% of. water usage.
(4) The cost of maintaining the ACT's open space watering system (which has an asset value in excess of $40 million) is $2,100,000 per annum. This figure covers all irrigated urban open space, as well as all of City Parks clients including the Federal Government. The cost of purchasing water is not included.
