Spicer Landfill will get up to $725,000 worth of upgrades in the next two years, Porirua City Council has announced.
The money will be spent on stormwater improvements, with the aim to minimise the discharge of silt into Porirua Stream and, eventually, the harbour.
A report to the council's wastewater treatment plant and landfill joint committee said Greater Wellington Regional Council issued two abatement notices to Porirua City Council, in March, 2011, and July, 2012, for breaching the landfill's consent.
The first was following a severe storm, where silty water discharged into a stream. The second abatement notice, which was precautionary, was successfully challenged by Porirua City Council.
Silt management, new piping and increasing the stormwater pond are among the work to occur.
The council's 2013/14 annual plan originally allocated $385,000 for this work. It is thought the upgrades will cost between $623,000 and $725,000.
Work could begin in summer and finish in 2016.
