Stormwater improvements for Auckland Council to mitigate flooding issues on Koru Street in Mangere.
Fraser Thomas delivered an effective solution to the flooding problems that regularly affected a number of properties through designing a stormwater management system with careful consideration of the whole system.
This comprised raising road crossing and footpath levels to direct stormwater flows into catchpits with significantly increased inlet capacities through specialised catchpit selection together with reconditioning and increasing the capacities of existing rock bore soakage on Mountain Road. A key component to ratify the project was proving the success of the stormwater management improvements through exhaustive soakage testing.
The project involved:
“The final outcome was great and Council have had no flooding complaints from the affected Property owners. The soak holes are performing better than expected. Hope to have the opportunity of doing another challenging project together in the near future.” – Vijay Mungro, Auckland Council
