South Wairarapa District Council’s project team remains on schedule as construction begins at the Martinborough Wastewater Treatment Plant (MWWTP). Planned upgrades at the Martinborough, Featherston and Greytown wastewater treatment plants will address each site’s treatment performance, regulatory requirements and conditions.
The MWWTP project works begin on 9 November 2026 and are scheduled for completion by the end of August 2027. Featherston and Greytown WWTP project works are programmed to begin on site in March and August 2027 respectively.
Mayor Fran Wilde says all three wastewater treatment plants will be upgraded by April 2028 to improve their environmental performance and support South Wairarapa communities’ aspirations for sustainable growth.
“By getting these essential upgrades into design and construction means regulatory requirements are being addressed”.
These capital upgrade works will result in improved:
- environmental performance through increased removal of nitrogen and phosphorus, clearer treated wastewater and better disinfection
- treatment during wet weather events and seasonal population increases
- reliability and resilience
- capacity for growth
A separate project at the Martinborough Wastewater Treatment Plant is to irrigate treated wastewater to a new site located to the north of Pain Farm. Resource consent applications to authorise this work were lodged on 12 August 2026 and are still being processed.
Mayor Wilde says we look forward to the completion of these projects.
