This project involved an 8Ha redevelopment of established grounds for a residential complex. This resulted in a large increase in impervious areas with strict consent conditions requiring stormwater runoff to be treated and detained onsite prior.
5 Filterra® prototypes were installed to treat approximately 1.4 ha of pavement runoff prior to being discharged 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.
