Pre­vent wa­ter con­tam­i­na­tion

North East & Goulburn Murray Farmer - - NEWS -

FOL­LOW­ING wide­spread flash floods and rain last month, farm­ers from across the North East are be­ing re­minded to re­move de­bris from wa­ter sup­plies as soon as pos­si­ble.

After a pro­longed dry pe­riod, wa­ter sup­plies are at risk of de­bris con­tam­i­na­tion fol­low­ing a down-pour.

Dams may be con­tam­i­nated with float­ing or­ganic mat­ter in­clud­ing straw, grass, leaves and ma­nure.

This can cause is­sues for the wa­ter sup­ply if it isn’t man­aged quickly.

Within a cou­ple of days, de­bris will sink and be­gin to break-down caus­ing the wa­ter to be­come pu­trid and po­ten­tially un­us­able for live­stock.

A chain mesh can be used to help clear de­bris, us­ing mesh sus- pended from a se­ries of floats to cre­ate a boom to clear the de­bris.

The boom is dragged across dams us­ing ropes at­tached to each end.

When time per­mits, sed­i­ment traps can be in­stalled to pre­vent de­bris from en­ter­ing dams.
