SYNOPSIS The sustainable yield of the main Alligator District Centre is between estimated current 'oeak water demand at .~ borefield at the East 120 and 130 kL/day. The the centre is 122 kL/day. Works are recommended to ensure the reliable supply of this amount of water to the Centre, and to improve the quality of information concerning water use and water resource potential at the District Centre. The estimated cost of these works is $173,500. The water resource and supply network has been analysed for its ability to cater for visitor growth over the next ten years of 10% per annum and .30% per annum. An additional bore is required to cater for 10% p'Br annum growth in water use, and reticulation and storage will need upgrading. The cost of this work is estimated to be $448,000. To cater for a 30% per annum growth in water use over ten years may well require the use of non-potable water from the East Alligator River, as the groundwater resource may not be sufficient to cater for this demand. However, the cost to supply this additional water from bores has been estimated and is $1,427,000. It is recommended no work to cater for future growth in .,ater use be undertaken until the estimates of water use and resource potential can be reviewed in one year's time. This will be after water use at the district centre has been monitored and water level measurements in existing bores have been collected on a regular basis. 005r-rJ
