The Northern Corridor Improvements (NCI) project aims to facilitate inter-regional travel between Auckland and Northland by building a new motorway connection between State Highway 1 and State Highway 18.
The designer on the project selected T-RECS to be applied to the large swale drain below the stormwater overflow ‘bubble up’ which was a steep slope (approximately 1V:4H).
The Riverside Grove, Tuakau, is a master planned residential development offering new sections ranging from 500m2 to 2000m2. The RainSmart System was chosen as the preferred method of stormwater detention.
