Principal: Wellington Water Limited
Construction company: Juno Civil
Juno Civil were commissioned to build a new reservoir to service a subdivision in Churton Park. With the high potential for seismic activity in the Wellington Region, Wellington Water Limited have started specifying the use of seismic restraint joints.
PAM Saint - Gobain have designed a range of 'Geoflex' couplings 100mm - 1800mm specifically for this application. These couplings are designed to simultaneously compensate for expansion, contraction as well as rotational and angular deflection.
Asmuss Water Systems offered these fittings to Wellington Water Limited as a solution, as they are manufactured and tested in accordance with the ISO quake resistant design standard (16134:2006). These are the first Geoflex couplers to be installed anywhere within Australia and New Zealand.
