Approximately 120m of the wastewater interceptor pipeline near Awapuni, Gisborne, needs remediating as part of the Gisborne District Council’s (GDC) programme to renew and rehabilitate existing and aging underground wastewater assets. An additional 382m of pipeline is to be inspected as part of this Contract in order to better understand its existing condition and need for rehabilitating.

GDC is seeking experienced and skilled CIPP suppliers to design, supply and install liners in an existing 750mm diameter interceptor to extend the useful life of these assets with at least a further 50 years and successfully install the liners before 31 March 2022 or earlier. Undertake CCTV and condition assessment of 382m of existing interceptors.

Two new manholes have been installed to allow for possible change in liner design based on the level of deterioration evident.

All suppliers and subcontractors who conduct work for, or on behalf of GDC, should be prequalified via SHE Software Ltd. Suppliers who are not currently pre-qualified through this scheme should go to the SHE Website or via the GDC website so that they can apply online to start the process.
