In December 2018 we completed work to upgrade the Cambridge wastewater pipe and the pipe bridge which crosses the Waikato river. The project is essential to cater for growth and future-proof our infrastructure.
What was involved?
Wastewater from residential properties north of the Waikato River is piped across the river to our treatment plant on the Leamington side of town. The old pipe was running at full capacity and not big enough to cater for present and projected future growth in Cambridge. The pipe bridge, located by the Gaslight Theatre, was also due for replacement.
We replaced the old pipe and increased capacity by 40%. We also replaced the pipe bridge and brought the whole structure up to modern standards, including earthquake resistance.

Done! We've completed work to upgrade the Cambridge wastewater pipe and the pipe bridge which crosses the Waikato river. Check the video to watch the progress race by thanks to time-lapse photography:
Facts and figures about this project
- The new pipe is 40% bigger
- 17,500 hours of on-site labour
- Two night shifts
- 100% environmental monitoring compliance
- 336 metres of new pipes
- 200 metres of gas main
- Excavated 400m3 of material
- 18 concrete foundations
- 5 cranes needed to launch the new bridge structure
- Size of one crane = 400 tonnes!
Project update - October 2018
Foundations and groundwork for the bridge replacement are now complete. Next, some of New Zealand's biggest cranes will roll into Cambridge to install the new wastewater pipe bridge, and are likely to be on site until late November.
Five cranes, including one massive 400-tonne crane, will be on site to swing the new bridge into place. The new bridge was built off-site in Napier and once it is securely in place, the old bridge and pipe will be removed.
The building site remains off-limits to the public, however those interested will be able to get a good view of the cranes working from the carpark near Resthaven on Vogel St.
