Te Awahou Foxton Flood Mitigation Project

Te Awahou Foxton has historically been affected by flooding on a regular basis. To this day, the township regularly experiences flooding due to localised heavy rain events. This causes disruption and damage, negatively impacting the lives of people living in the town.
 
Foxton currently has flood protection estimated to be 1-in-2 to 1-in-5 year protection. There are a range of drainage and flood protection assets in and around the township. However, there are limits to the current level of services provided by private, Horizons, and Horowhenua District Council assets.

The Te Awahou Foxton Flood Mitigation Project aims to address the persistent flooding issues in Foxton township, caused by overtopping and seepage from the Foxton East Drainage Scheme. The exact works proposed have changed over time, with a range of factors – not least the Covid-19 pandemic – impacting the project negatively. 
 
A governance group was established in 2024, featuring representation from Horizons, Horowhenau District Council, iwi, hapū, and others in the community. The aim is to work collaboratively to ensure solutions work for the community and local environment. The group is taking a fresh approach, ensuring they deliver tangible solutions for residents and landowners. 

The project currently plans to deliver the following:
  • Sheet piling along the true right bank of King’s Canal between Avenue Rd and Cook St. This will mitigate seepage and reinforce the current bank. 
  • Temporary tractor pumps have been ordered. The intent for these is to provide for the removal of surface water from Purcell St during rain events when water cannot flow to Piriharakeke Manawatū River loop due to tidal influences.
 
Horowhenua District Council are also doing inspections of parts of their stormwater network, using closed-circuit television equipment to identify its condition and potential upgrades.
