Waipawa Trunk Sewer Main Renewal Project

Client: Central Hawke's Bay District Council

    TPG was engaged by Central Hawke’s Bay District Council (CHBDC) to assist with the Waipawa Trunk Sewer Main Renewal project. The project consisted of the rehabilitation of 2.2 km of an earthenware sewer line located east of the Waipawa town centre, that had multiple defective joints, allowing groundwater infiltration and root ingress.

    As the sewer main is largely located within private property, we assisted CHBDC with the property aspects of the project, including:

    • Undertaking due diligence to establish existing rights in relation to the pipeline, which included a mixture of registered easements and statutory rights and powers under the Local Government Act 2002

    • Establishing a methodology and timeline for engagement with properties both directly and indirectly affected by the project

    • Undertaking landowner engagement and communications ranging from properties indirectly affected by roadside establishment during construction at manhole locations, through to engaging with directly affected landowners with manholes located within private property.

    Where access to private property was required, we ensured that the landowners were contacted directly, the works discussed, and the correct notices under existing easements and statutory rights for entry were provided in advance of the works commencing.

    Both CHBDC and the contractor utilised the GIS project reporting tool developed for the project. This imported CHBDC’s existing asset data in addition to key property details, methodology for obtaining access and a risk assessment. It also tracked and reported on progress with landowner engagement in addition to capturing key details for construction in relation to each property.  

    Following completion of the relining works , the second phase of the project is upgrading the existing pump station and power supply to enable a second pump to be commissioned.
