Disinfecting Your Well After Flooding
This method is for the disinfection of a well water supply, water storage tank, water carrying pipe work and hot & cold-water cylinders. Approximately 1,100 litres of water will be used.
Caution: if you have a filter or any other type of water treatment on any part of your system, consult your supplier before following this procedure. Heavily chlorinated water may affect the filter or the chlorine may be absorbed by the filter, rendering the procedure ineffective.
Disinfection products sold for use on the farm will be acceptable for use in disinfecting wells. However, it is important to seek advice about their use and it is advisable to always use the products in about 25 litres of water.
N.B. This method is only suitable as a once off shock disinfecting procedure and cannot replace a proper treatment system if your water supply needs continuous disinfection.
