Intensive roadworks to replace Annesbrook’s over-capacity wastewater systems will be paused over the Christmas holidays to minimise traffic disruption.
The work began in September to create a new wastewater diversion system along Whakatu Drive. It has seen the passage between Beatson Rd and Annesbrook Dr down to one lane for part of the past two months.
Council started the work after complaints over sewage overflows on several properties in the area following heavy rain.
“With an increased number of houses connected to the existing system and with future development in mind, there is a need to increase the resilience of the sewer pipe network, especially during heavy rainfall,” council says.
The current work is to install a section of pipeline from Stafford Avenue through the Annesbrook roundabout and up Whakatu Drive to a new manhole.
It hopes that upgrading the wastewater system in this area will minimise the impact of future sewer overflows in wet weather events. The new pipe will connect into the Quarantine Road network via Annesbrook Drive south.
Construction will take place in two stages to minimise traffic disruption over the Christmas and New Year period.
This has seen the southbound lane on Annesbrook Drive closed to traffic, with heavy motor vehicles not permitted to use sections of Nayland Road.
Stage 2, starting after Christmas, will see the upgrade extend from the section of Railway Reserve that intersects Quarantine Road and up along Annesbrook Drive to eventually connect with the pipe laid down during the Stage 1 work.
Council will take advantage of the wastewater construction works to simultaneously upgrade a section of footpath along Annesbrook Drive from Stafford Ave.
Council’s group manager infrastructure Alec Louverdis acknowledged there would be disruption to traffic while the work took place and thanked the community for their patience.
“The work we are doing here will provide the city with enhanced resilience to sewer overflows from heavy rainfall events. The impact of climate change means we will see major storms more frequently, and we must make sure Nelson’s wastewater system is designed to cope with this.”
The whole project is set to be completed by March next year.
