The Christchurch City Council has dropped a plan to install pressure wastewater systems in thousands of properties, rather than change its consultation process or appeal against a High Court ruling.
About 800 pumps have already been installed in a bid to upgrade the damaged pipe network and replace the traditional gravity system.
The installations were disputed by some residents who were awarded a judicial review by the High Court.
The council's acting general manager for city environment, Terry Howes, says the council has had to carefully consider the conclusions in the recent judgement and the relief awarded.
The court found the council's decision for the Richmond area was flawed because there was no consultation with property owners.
The total cost of the repair of the city's broken wastewater systems is estimated at $844 million.
