Stage 2 Paremata wastewater upgrades – Investigations
Wellington Water has issued a letter regarding planned investigations into wastewater pipe replacement along Paremata Crescent and Papakowhai Road and replacement of 4km of wastewater pipe along SH59 to the wastewater holding tank, currently being constructed. The letter can be accessed at the bottom of this article. An update can be obtained from the Wellington Water web link: https://www.wellingtonwater.co.nz/about-us/news-and-media/news-and-media-2/work-begins-on-paremata-wastewater-pipe-replacement .
The Paremata Residents Association welcomes the upgrading of wastewater pipe south of Paremata Bridge, which is expected to improve wastewater flows south of the bridge. That should help relieve congestion that is occurring north of the bridge, improving flow and reducing sewer smells currently affecting too many residents along Mana Esplanade.
However it is unlikely to prevent manhole discharges during very wet weather and the resulting pollution of our inlet. That will not improve until the sewer system along Mana Esplanade is upgraded. Disappointingly, that is not planned until after 2030. In the meantime these overflows could be reduced by stormwater and groundwater inflow and infiltration (I & I) investigations and prevention.
The Paremata Residents Association will continue to lobby the Council to upgrade the sewer main along Mana Esplanade sooner, and Wellington Water to carry out I & I investigations.
