Wellington Regional Council will consider the feasibility of an emergency water reservoir on the outskirts of Porirua to help resupply residents more quickly after a big earthquake.
At a council meeting last week, councillors approved a feasibility study for a possible 500 million-litre reservoir costing an estimated $19 million on a 100-hectare site near Takapu Rd.
From the hilltop site, gravity would push the water to Porirua, Wellington and, if necessary, the Hutt Valley without power.
The reservoir's capacity would be sufficient to supply Porirua and Wellington City for about 100 days while repairs to pipes and other infrastructure were carried out.
After the meeting, chairwoman Fran Wilde said pursuing the reservoir option was an integral part of the regional council's long- term commitment to earthquake- strengthening infrastructure.
