Fulton Hogan Petone to Melling Cycleway Underpass

The Requirement

Condor was approached by Fulton Hogan to assist with the removal of suspended solids, which would affect the water quality discharged during the construction of two rail underpasses.

The Solution

The first underpass being on Parliament Street with had very limited space on site, so the compact Condor XL Water Treatment System (WTS) and associated pumps were recommended for this project.

The second underpass was constructed at Pito-one, which is situated just south of Petone Station.

To minimise disruption to train commuter’s works at Parliament Street were done over the Labour Day long weekend, and works at Pito-one over the Christmas holiday period, and Fulton Hogan worked 24-hour-a-day shifts to get the underpass completed.

With the Water Treatment System only being required for a short length of time, the systems and associated pumps were hired and were delivered to the site, set up, and commissioned by Condor staff.

The Result

The end result was that the total suspended solids (TSS) in the water discharge was kept well within the required parameters to meet compliance with the site discharge consents.
