Leeston Road Culvert Upgrade
Division: Three Waters
Client: Contracted by Corde; Completed for Selwyn District Council
Location: Leeston, Selwyn
Status: Completed 2026
Taggart delivered the Leeston Road box culvert upgrade, a Three Waters project contracted by Corde and completed for Selwyn District Council. The work involved installing a new concrete box culvert, 2.5m wide, 1m deep and 12.4m long, complete with new headwalls and wingwalls, to reduce flood risk and increase stormwater capacity at the site.
The existing culvert stayed live and operational throughout construction, with ongoing dewatering and environmental requirements around the waterway to manage alongside it. A storm event partway through closed Coes Ford and Chamberlain Ford, causing delays, but the team completed the works within the four-week programme, and Leeston Road has since returned to normal use.
From start to finish
