This project involved an 8Ha redevelopment of established grounds for a residential complex. This resulted in a large increase in impervious area with strict consent conditions requiring stormwater runoff to be treated and detained onsite prior.

5ea UrbanGreen BioFilters were installed to treat approximately 1.4Ha of pavement runoff prior to discharge into detention chambers.

ChamberMaxx was chosen for detention due to its large storage capacity, full traffic rating, ease of installation and low cost. Approximately 677 chambers were used to detain 2200m3 of runoff. Making this the largest ChamberMaxx project in New Zealand to date.
