Dixon Street pump station and rising main- a first for New Zealand
At a glance
Central Wellington is set for huge growth, with a population increase of 21 percent expected over the next 30 years.
GHD was engaged by Wellington Water to carry out the investigation, design, tender and contract supervision for a new wastewater pump station and associated pipework, under Victoria and Dixon Streets in Central Wellington.
The Dixon Street Pump Station project is the first to be constructed in Central Wellington in over 40 years. This allows Wellington Water to provide wastewater services to a growing population, and relieves pressure on other pump stations around the city, reducing the chance of overflows into the harbour.
Given the lack of space, the central location presented a significant challenge, requiring an innovative approach that would work within the space constraints, while still delivering all the services required.
Alongside Brian Perry Civil, we’ve designed and supervised construction on the new pump station using the innovative segmental caisson method.
