Take care with ef­flu­ent ponds af­ter rain

Hamilton Metro News - - News -

Fol­low­ing the heavy rain that’s struck the re­gion re­cently Waikato Re­gional Coun­cil is re­mind­ing farm­ers it can help with ad­vice on man­ag­ing ef­flu­ent pond lev­els.

Ef­flu­ent should not be ir­ri­gated on to sat­u­rated pas­tures as this risks con­tam­i­nants get­ting into wa­ter­ways and af­fect­ing their health.

How­ever, heavy rain help­ing to fill up ponds means farm­ers can be un­der more pres­sure to empty them to stop ef­flu­ent spilling out in large and dif­fi­cult to man­age amounts, which can end up in wa­ter­ways.

“We ac­knowl­edge some ponds will be close to over­top­ping due to the rain but farm­ers still need to do every­thing they can en­sure they don’t over­top and that ef­flu­ent is not ap­plied to sat­u­rated pas­ture,” says the coun­cil’s farm­ing ser­vices team leader Stuart Stone.

“They should ac­tively man­age their ponds and take all rea­son­able steps to pre­vent ef­flu­ent from en­ter­ing wa­ter­ways.”

Op­tions for low­er­ing pond lev­els other than ir­ri­gat­ing to pas­ture in­clude look­ing to trans­port ma­te­rial away by tanker for dis­posal or us­ing some­one else’s sur­plus stor­age. It’s also worth en­sur­ing stormwa­ter sys­tem flows are di­verted away from ponds.

“Also nor­mal pas­ture ir­ri­ga­tion can oc­cur if con­di­tions are suit­able,” says Mr Stone. If farm­ers feel their pond is at risk , or they want other ef­flu­ent-re­lated ad­vice, they can call the farm­ing ser­vices team on 0800 800 401.
