“It looked quite spectacular and the plume was twice the height of the truck - about 5m I’d say.
“I took a few photos and shot some video footage.”

The council’s contractors have been working to replace the 100-year-old stormwater pipeline along part of Smithfield Rd, Konini and London streets with an upgraded system.
The project is part of the council’s wider programme of works within its 30-year infrastructure strategy to upgrade the level of service and meet the requirements of the growing development demands throughout the network.
The work began in March last year and is now at the construction stage.
The programme includes the installation of 474m of 900mm pipe from Moore Avenue to Konini St along Smithfield Rd and London St.
The work also includes the installation of 200m of 225mm wastewater main from Moore Ave to Brooking St and along Smithfield Rd.
It is estimated that the third and final stage of the work will be completed in July.
