Challenge
Queenstown Lakes District Council required the entire Kirimoko subdivision stormwater to be captured in an inspectable infiltration system, relieving pressure on an already stressed downstream network as 37 new lots added impervious area.
02
Solution
GRAF supplied EcoBloc Inspect Flex with four Vario access shafts beneath carpark and reserve areas. Benchmark Construction completed 300 m³ storage across a 42 m footprint in 1.5 days.

Outcomes
- Inspectable infiltration per council requirements
- 1.5-day install versus weeks for poured concrete
