In November 2015 Watercare awarded a $21.7m contract to HEB Structures to construct a large underground waste water storage tank and pump station including several large pipelines in and out of the tank. The new storage tank and pipeline will provide for growth in the area and reduce wastewater overflows during rainfall events into the Devonport peninsula and East Takapuna areas.  

A key part of HEBs successful tender strategy to secure this contract was to offer the client the full capabilities of the HEB Group.  To that end HEB Construction’s Civils and Structures teams leveraged their experience and reputation in completing concrete structures and pipelines to provide Watercare with a complete offering.

HEB Construction constructed:

• A new 3,500m3 below ground wastewater storage tank and pump station
• A new 630mm diameter rising main pipeline, approximately 1,080m in length
  from the proposed pump station along Fred Thomas Drive and Taharoto Road,
  to Karaka Street;
• A 225mm/375mm/450mm diameter gravity main from the existing pump station
  (to be decommissioned as part of the contract) through private property to the proposed pump station approximately 470m in length;
• A new 525mm diameter pipe connecting a section of existing network approximately 85m in length along Esmonde road.

The rising main, gravity main, and the Esmonde Road link was constructed by HEB Construction’s Utilities Division.  The storage tank and pump station was constructed by HEB Structures.
