This project aimed to reduce flooding on Mair Street and neighbouring private properties. 

A new concrete stormwater line was installed from Mair Street, along Hatea Drive and down the north side of Rurumoki Street.

This is a larger pipeline (between 750mm and 875mm internal diameter), which increases the capacity of the network to convey stormwater. New catchpits at Mair Street were also installed. 

While work was carried out on Rurumoki Street, we took the opportunity to renew the watermain. The existing watermain on the north side was installed in 1939 and required replacement.  

This project will prevent surface flooding during regular rain events (any events smaller than a five-year reoccurring rain event), but surface flooding of the roads is still expected during large rain events, as the stormwater network is designed with capacity for one-in-five-year events.

Roads play a key role in stormwater systems, conveying stormwater runoff to catchpits.
