INTRODUCTION In November commissioned 1990 the Power and by 1:he Australian Water Authority (PAWA) was National Parks and Wi1dlife Service (ANPWS) to undertake an assessment of the water supply at the East Alligator District Centre, Kakadu National Park, and to assess the ability of the current system to meet future proj ected demand (Attachment 1). Water is supplied to ranger housing, camping areas, a youth hostel, shop, and day use areas from four bores, of which only two are usually used. The first bores drilled in the area were constructed in 1976 (RN 8918 and 8919) and served a day use area on the banks of the East Al1igator River. These bores have since been decommissioned and not replaced. The first bore providing water to the East Alligator District Centre (RN 20480) was constructed in 1979. Since then other bores have been constructed and additional reticulation and storage put in place, as the District Centre has expanded and water demand increased. During the dry season of 1988 problems Were encountered with the water supply due to the bores not being able to produce water for periods of up to 12 -14 hours. Leaks in the system have been a problem too, depleting much of the storage on some occasions. In early December 1990 and again in early January 1991, inspections of thE' water supply system were undertaken by PAWA staff. This report documents the subsequent assessment of these site visits and predictions concerning the capacity of the current water sup:?ly system to meet present and future water demands. Recomme,ndations concerning changes to the present system are outlined and estimates are provided for the cost of implementating these recommendations. 005MJ
