Pumping 24,000 flushes uphill: North New Brighton to Aranui
How does it all work across the city?
Pages Road new pump station, Bexley Reserve
• Before the building began, the ground was significantly “improved” or made stronger in the event of future earthquakes by injecting columns of grout/ concrete under the station site and around the surrounding area. (See drawing of the columns.)
• The pump station has an on-site generator which can run for three days if there is a power cut.
• The generator building is fireproof. It has a special link installed that, if burnt out, will stop the flow of fuel to the generator, isolating the fire to within the fireproof walls.
• The generator sits on special bearings, which enables it to withstand possible future earthquakes.
• There are also two biofilters in the area around the pump station. These help to reduce any odours. Fans in the pump station suck the air to the biofilter. The air passes through the bark which absorbs odour.

• The concrete panels are textured to reflect and link with the Port Hills and Banks Peninsula area, visible to the south.
• All storm or rain water on site goes into a garden area for filtering before it discharges into the storm water system, thanks to thoughtful, sustainability-minded landscape design from Chris Greenshields.
• Planted areas are designed to screen and soften the site while adding to the environment in this area.
