Effluent handling specialist Hi Tech Enviro Solutions showed several new products at Fieldays, among them a shore-based stirrer and a portable skid unit for powering high output effluent pumps.
But it will not be blanket watching of any and every farm, a practice stopped in 2014 when the milk payout turned downward.
Farmers said then that they found the monitoring stressful and intrusive and that they had nothing to hide.
Councillors voted 10 to 3 to resume surveillance. Some say non-compliance is increasing among farmers who believe they can get away with it in disregard of its impact on the environment.
The councillors heard that an ‘effluent review’ three years ago -- farm visits by council staff -- had been dropped in favour of working with farmers and landowners to tackle the issue.
But now the council estimates 808 (19%) of Waikato’s 4255 dairy farms do not comply with the rule that effluent storage must be effective 365 days of the year.
The council will mount an aerial watch on these farms rather than blanket survey all farms.
Councillor Stu Husband, a dairy farmer at Morrinsville, opposed the move, calling it “a huge step back for this council”. He said the correct approach is to visit farmers, identify the problem and make a plan to put things right.
The 19% non-compliance figure is misleading, Husband said. 95% of farmers comply with the rules but might have management issues at certain times of the year.
“We don’t like being spied on when the farms we operate are also our homes,” Husband said.
Helicopters are another way for council staff to ensure farmers’ compliance, said WDC resource use director, Chris McLay.
“We are not seeking a blanket aerial monitoring initiative; we just want to target high-risk properties,” he said.
Te Aroha dairy farmer Andrew McGiven, the Federated Farmers Waikato president, said Feds agreed in 2014 with the stopping of helicopter surveillance, but times have changed and farmers now need to be seen doing things properly.
“We understand the new regime will be one of risk management, i.e. identifying farms with poor or borderline storage and discussing remedial actions face to face.
“We also understand this work will be done using the latest technology such as real-time satellite systems -- less invasive than helicopters and better value for ratepayers.”
