A unique, award-winning catchpit improves stormwater quality.
Improving the stormwater quality of Ōtāhuhu was one of the key goals of the Ōtāhuhu Town Centre streetscape upgrade project. Several bio-filtration garden catchpits have been installed along the newly-refurbished streets to promote a healthy environment.
The project made a unique shift in effective gross pollutant (litter and debris greater than 5 millimetres in size) pre-treatment and management using a garden catchpit design.
