RECOMMENDATIONS FOR FINISHING, OPERATING AND PROTECTING GROUNDWATER BORES Attention to the foilowing points will ensure a long and safe life for the bore supply and help prevent pollution of the groundwater resource. . 1. Construct a concrete spron around the bore head to prevent surface lIow, seepage and waste from entering the bore. 2. Seal the space between the casing and pump equipment to prevent entry of vermin, dirt and pollutants. 3. Maintain pumping eqUipment in good order to prevent pollution. Prevent spillage of fuel and oil on the ground around the bore. Store fertilizer and other chemicals at least 50 m away. 4. Keep stock away from the bore head. Discourage domestic activity at the bore. The first tap on the pipeline should not be less than 5 m from the bore head. 5. Pumping the bore at higher than recommended rates may fork the bore leading to instability or pump maintenance problems. Seek the professional advice of an hydrogeologis! or groundwater engineer. 6. If the bore is no longer required, the casing is to be removed or securely capped and the bore backfilled with clayey material. A cement plug may be required in some instances. In addition, please ensura that the BORE IDENTIFICATION TAG is retained securely at all times. The registered bore number is Water Resources Division's only reference to the scientific and engineering data on this bore, and hence important to WRD's further advice to bore owners.
