7 tips to pro­tect­ing your bore

NZ Lifestyle Block - - Our Water -

If you have a pri­vate groundwater well or bore, there are some im­por­tant steps you can take to look af­ter it and min­imise the risk of you or your fam­ily get­ting sick:

En­sure your bore is lo­cated as far as prac­ti­cal from po­ten­tial sources of con­tam­i­na­tion such as sep­tic tanks, of­fal holes, and ef­flu­ent dis­posal ar­eas.

If you are think­ing of in­stalling a bore, your coun­cil will be able to ad­vise on ap­pro­pri­ate set-back dis­tances from po­ten­tial sources of con­tam­i­na­tion.

To pre­vent stormwa­ter and con­tam­i­nants en­ter­ing the wa­ter sup­ply, the top of the bore should be se­curely sealed; the bore cas­ing should ex­tend above the ground and ide­ally be sur­rounded by a slop­ing con­crete pad.

Where nec­es­sary, fence around the bore to pre­vent stock ac­cess.

Be sure to in­clude a back­flow pre­ven­tion de­vice to stop con­tam­i­nated wa­ter flow­ing back into your wa­ter sup­ply.

Wa­ter qual­ity can be checked by col­lect­ing a sam­ple and send­ing it to an in­de­pen­dent and ac­cred­ited lab­o­ra­tory for test­ing. Most labs can send out simple test kits and in­struc­tions.

Un­used or aban­doned bores should be back­filled and se­curely sealed to pre­vent con­tam­i­nants en­ter­ing the aquifer.
