Update - 21 June 2019

Council has completed a rigorous tender process and has awarded the contract for portion 2 and 3 to Fulton Hogan Ltd.

Works are expected to start on Separable Portion 3 - Savage Crescent, Carpenter Street and Churchill Street Improvements in early July 2019 to up size and extend the stormwater network as well as replace sumps and pits to improve network performance.

Following this piece of work, the team will move to Woburn and Wilder Street to extend the stormwater network to an open drain. Works are expected to take approx. 4 months, and be completed by December 2019.

Update - 05 April 2019

Council has released this tender to the market as we aim to engage a suitable contractor to undertake these works. 

Council has proposed 3 separable portions (SP) to this project as outlined below; 

  • SP 1 - Waipukurau Service Lane Overflow/ Ruataniwha Street
  • SP 2 - Woburn Street and Wilder Street Improvements
  • SP 3 - Savage Crescent, Carpenter Street and Churchill Street Improvements

Update - 6 November 2018

A project has begun to improve the stormwater network in Waipukurau and reduce flooding. Council is currently defining the scope and design with our consultant to evaluate where best to focus our attention.

Update - 05 April 2019

This portion of work proposes to construct a new secondary overland flow path to diver flood water entering shops in Ruataniwha Street, this would be achieved by lowering the walkway between No 34 and 36 Ruataniwha Street and attenuate the flow within the dish-like profile of the service lane.

A block-wall (450mm high and 35m long) would be constructed to prevent the ponded volume from tipping into timberyard.

The expected ponding volume is approximately 700m2 with a maximum depth of 400mm.

This option has the potential to provide more storage at a later date when the service lane is resurfaced in the next 5-10 years.

Council is currently engaging with landowners and those affected. No works will take place until agreement is obtained.

Update - 05 April 2019

An easement is planned to be established through 25 Woburn Street to provide a flow path to the open drain located parallel to Wilder Street and a route for piped infrastructure.

This improvement is very important considering the future development. It is expected that any rural surface flooding caused by the upstream upgrades would be comparatively minor in nature. 

To provide an outlet for the surrounding catchment a stormwater manhole will be constructed at the junction of Woburn and Wilder Street and a DN675 stormwater pipeline would be laid to the open drain.

All the 1 in 10 year overland flows arriving at the end of the Woburn Street would be collected through a combination of super-pits and back entry sumps  and conveyed through the pipe and discharged into the open drain. Large flows would pass across the easement in a depressed swale and discharged to the drain.

Update - 05 April 2019

This project focuses on improvement of the level of service to the properties on Savage Crescent. The existing network carrying stormwater flows through Savage Crescent would be diverted at the corner of Carpenter Street and Savage Cresent by constructing 525mm and 600mm pipes along Carpenter Street and Churchill Street and discharging excessive stormwater flow into the kerb and channel in Churchill Street.
