Calculating The Amount Of BoreSafe™ Required
Calculate the depth of water in the bore
Total bore depth (metres)______ minus depth from the ground to the water level (metres)______equals ______.
Depth of water. i.e. bore hole is 100m deep, the water level is 40m from the surface – water depth is 60m.
Ascertain whether you require a standard or a shock dose
Standard Dose – A regular maintenance dose when cleaning a bore regularly within 12-month periods.
Shock Dose – Required when the bore hasn’t been cleaned for long periods and has solidified iron buildup.
Check the dosage guide (please note this is a guide only) for the dosage required for the diameter of the bore and multiply that by the depth of water in the bore.
- Calculate the amount of BoreSafe™ required (as above).
- Dissolve the required amount of BoreSafe™ in a bucket(s) of water. For every kg of BoreSafe add 10 litres of water.
- Divert the discharge of the bore pipework back down the bore so the system recirculates (ensure this is done within the specs of the pump).
- While the system is recirculating pour the dissolved BoreSafe™ down the bore. Leave the system recirculating for 6-8 hours (the water may change to a green colour).
- Flush the system by moving the discharge away from the bore and ensure the water drains away from the bore. (BoreSafe™ is biodegradable – however, avoid foliage that could be damaged and areas that could be stained).
- After flushing for 10-20 minutes, to ensure all the BoreSafe™ is flushed out use the provided test kit. Fill the sample bottle with 100 ml. of the flushing water and add 10 drops of the reagent. Agitate and leave for 3 minutes, then observe. If the solution turns purple, the BoreSafe™ has been flushed completely. If the solution is any other colour, more flushing is required and then repeat this step.
