What we are doing

  • Downer as part of SCIRT is repairing the earthquake damaged wastewater system in Spreydon.
  • Starting Monday 13 February 2017, we will be repairing three wastewater laterals on Somerfield Street. See Map 1 for location of works.
  • This work will be done in two stages and take about 10 days to complete, subject to favourable on-site and weather conditions.
  • A lateral is the pipe that connects a property to the wastewater pipe in middle of the street. We will be digging an access point in the middle of the road to remove a section of the damaged lateral and replacing it with a new piece.
  • Once the new pipe is laid the trench will be backfilled and compacted. The access point will then will be sealed by a separate roading crew the following week.
  • Stage 1 will involve repairing two laterals outside #107 and will take about one week to complete
  • Stage 2 will follow stage 1 and includes repairing a single lateral outside #103. This will take about three days to complete.



General impacts

  • We will be dewatering, which lowers the ground water within the access point. The ground water is pumped into a sediment tank which will be used to filter the ground water before it is released into the storm water system.
  • You may hear a light humming noise coming from the dewatering pumps running 24 hours a day.
  • We will try to keep disruption to a minimum and we apologise for any inconvenience.
  • This work will have no effect on your services.


Traffic impacts

  • Two-way traffic will be maintained on Somerfield Street.
  • There will be no on-street parking around the worksite.
  • Please be alert to changes in traffic management, follow signage and drive to the changed conditions.
