This is Aquatech's first project in New Zealand and is part of a $200million transport hub. The project brings together buses, trains and ferries in downtown Auckland and is the first time in 73 years trains have arrived in the heart of the city.

AQUATECH SYPHONICS' were contracted to drain the Glasshouse, a glass and steel structure linking the refurbished CPO building and the new underground station. To maintain the light, airy transparency of the Glasshouse, it was important to ensure that more practical features, such as the roof drainage system, were as inconspicuous as possible.

The high level pipework was installed in stainless steel to match the finishes inside the building and to be as unobtrusive as possible. The whole roof is drained from eight roof gutters to just four 75mm downpipes. The systems are fixed directly to the structural steel and are sheathed in some areas to give the illusion of a continuous pipe. At the base of each downpipe uplighter fittings are installed around the pipe to maintain the lighting effect within the building.

Installation time including procurement, site welding and fabrication was only 3 weeks and was finished well within program to meet the first stage and official opening deadlines.
