This report provides details of construction and pumping recommendations for the bore drilled on Namurgadanu outstation. The outstation is situated some 350 km east of Darwin at AMG co-ordinates 943 533 (Tomkinson 1:100 000 sheet 5773). Population of the outstation fluctuates between 20 and 50 people. Bores 22898, 22899, 23190, 23191, 23192 and 23193 were drilled. Bore 22899 was successful. The work was carried out in September 1984 on behalf of the Department of community Development and involved preliminary investigation, construction and testing of the production bore.

BORE MAX. CONTINUOUS PUMPING RATE MAX. PUMP SETTING BELOW GROUND LEVEL MIN. INTERNAL BORE DIAVillTER 22899 0.3 Lis 25 m 127 rom These recorrnnendations are based on available hydraulic and hydrologic data considered safe, but not conservative. Exceeding the pumping rate will fork the bore which may lead to pump problems. Recommendations for finishing and protecting of bores Attention to the following points will ensure a long and safe life for the bore supply and help prevent pollution of the groundwater resource. (1) Construct a concrete apron around the bore-head approximately 2 m in diameter. (2) Prevent drainage of surface flow and waste water to the bore in the vicinity of the bore. (3) Prevent spillage of fuel and oil on the ground around the bore. (4) First tap on the pipeline should not be less than 5 m from the bore-head. (5) Seal the space between casing and pump equipment to prevent ingress of vermin, dirt and pollutants. (6) If the bore should be no longer required, the oasing is to be securely capped and the bore backfilled. (7) Maintain pumping equipment in good order to prevent pollution. In addition, please ensure that the BORE IDENTIFICATION TAG is retained securely when the bore is equipped. This is best done by setting the bore cap into the concrete surround when it-is cut off to allow equipping of the bore. 5 : KARP
