3rd Annual Workshop and Field day 17 June 2025
Join us
Join us at the 3rd Annual Workshop and Field Day, focused on Catchment Solutions: Working together
Join us on Tuesday 17 June at 9:15 AM at the Centralines Depot in Waipukerau for a day filled with learning and networking, and the opportunity to visit pilot trials of a Detainment BundPS120© and a woodchip bioreactor.
This event is a great opportunity to connect with experts in the field and gain valuable insights into sustainable catchment management practices, while enjoying a complimentary morning tea and lunch at the Centralines Depot
Come discover and discuss
Edge–of–field water quality mitigations – what’s involved in developing these novel practices/technologies
Catchment activities – catchment workshops, farm water testing and potential mitigation strategies at farm- and catchment-scales
Pilot demonstrations – visit and learn about construction of pilot trials of a Detainment BundPS120© and a woodchip bioreactor in the Maharakeke and Pōrangahau sub-catchments
See you there!
date & time
tuesday 17 june 9.15am – 3.30pm
Morning: workshop presentations
speakers:
There will be workshop presentations with invited speakers from the Lake Whatumā Management Group, Rangitāne o Manawatū, Tukituki Land Care/Pōrangahau-Maharakeke Catchment Group, Hawkes Bay Regional Council, NZ Landcare Trust, and Massey University Farmed Landscapes Research Centre.
They will share and discuss their perspectives (Mātauranga Māori, Farming, Policy and Planning, and Science and Advisory) to collaboratively work together to find and implement targeted and effective catchment-scale water quality solutions.
location
17 coughlan road, waipukerau, hawkes bay 4200
lunch
Lunch will be provided & tea/coffee
afternoon:
field visits to pilot demonstrations:
Visit and learn about the construction of pilot trials of a Detainment BundPS120 and a Woodchip Bioreactor in the Maharakeke and Pōrangahau sub-catchments.
If you would like a taster of what the visit entails, watch the two virtual tours of these edge-of-field water quality mitigations below.
Take a virtual tour of the two pilot mitigations
The Maharakeke Pōrangahau Bioreactor tour
Take a tour of the Maharakeke Pōrangahau woodchip bioreactor – a novel edge-of-field practice being developed to reduce losses of nitrate from agricultural lands. They harness natural biodegradation processes to create an environment where soil microorganisms effectively break down nitrate in drainage waters. They are easy to build, require low maintenance, and last 10-15 years before the woodchips need to be replaced to maintain their effectiveness.
The Maharakeke Pōrangahau Detainment Bund P120 tour
Take a tour of the Maharakeke Pōrangahau Detainment Bund PS120© built in this catchment. It is a special type of sediment trap to temporarily detain stormwater runoff from pasture lands. It intercepts stormwater run-off by briefly ponding it on pasture to reduce significant amounts of sediment, phosphorus, and pathogens. Runoff ponding is achieved by constructing low earth bunds across valley floors where water flows during high-intensity rain storm events. Water ponding is controlled by a flow structure and a spill way in case of a very high runoff event. Pasture growth in the ponding area is not compromised due to temporary storage and then release of the ponded water.
