The expo comes at a time when the regional council is looking to do more to protect water quality and water resources in the Waikato from the impacts of intensive agriculture, especially nutrients and bacteria from dairying and other livestock farming.
"Expos are a good way of providing information to farmers about having an effective effluent system which helps them maximise their profits and minimise their environmental footprint," says Ms Ody.
"Besides what the exhibitors have to offer, there will be a number of optional seminars and demonstrations to take in, which will be repeated throughout the day."
Regional council staff will be on hand to answer questions about complying with council rules on effluent management.
Outside the venue, visitors will be able to see demonstrations of a range of effluent irrigators.
The Waikato expo last year was the first of its kind in New Zealand. Its success has resulted in other regions, including Canterbury, hosting similar events this year.
