Case-study Catchments

The Catchment Solutions Project has been working in community catchment groups to help identify critical contaminant flow pathways. The catchment groups are across the North Island and have been monitoring streams, collecting water samples and getting them tested with the help of the Catchment Solutions project.

Explore the case study catchments below to find out what each catchment group has learned about innovative edge-of-field mitigation technologies. Read how they are trialing practical installations such as bioreactors, Detainment Bunds PS120© and wetlands in their catchments to mitigate the effects of contaminants going into their waterways .

Haynes Creek Catchment

The Haynes Creek catchment is situated 15 minutes north of Fielding and is part of the wider Manawatu river catchment. The area is about 6800 hectares, and stretches from Cheltenham to Kimbolton.

Learn how the group have been monitoring water quality in the catchment and how they collaboratively decided to build a bioreactor to mitigate the effects of nitrate going into their waterways.

Mangaone Catchment

The East Mangaone catchment is located in the Tararua area, also part of the wider Manawatu River catchment.

Learn how the community have worked with the Catchment Solutions project to identify freshwater contaminants in their area and how they are trialing the first Detainment Bund PS120 ever contructed in the Lower North Island.

 

Lake Whatumā Catchment

Lake Whatumā is located in Central Hawkes Bay or Tamatea. It used to be the major source of food for the area.

Read how the restoration of the lake is being  undertaken by the Whatumā Management Group (WMG) and what challenges they are facing to mitigate the effects of contaminants that have affected the lake. 

Maharakeke Pōrangahau sub-catchment

The Maharakeke Pōrangahau sub-catchment is located in Central Hawkes Bay.  

Read how the sub-catchments community and farmers are working together in reducing nutrient losses and improving water quality outcomes in the catchment streams.
