Tayler Street Wastewater Pipe Renewal (Eltham)

⁠⁠⁠Overview

The South Taranaki District Council (STDC) proposes to renew an existing section of wastewater pipeline located in Tayler Street, Eltham. The pipeline has been identified for renewal following CCTV inspection and condition assessment, which confirmed that the asset is in poor structural condition with multiple cracks and dips. Due to the extent of deterioration, the pipeline is not suitable for relining and requires full replacement.

Scope

The scope includes:

• Installation of the replacement pipeline at the same alignment and grade as the existing infrastructure to maintain hydraulic performance and continuity of service
• Construction using open trench excavation methodology, given the age and condition of the asset
• Management of ground conditions during construction, as ground conditions are currently unknown
• Renewal of approximately 113 m of Ø150 mm wastewater pipeline between ELWWMH00715 and ELWWMH00720, replacing the existing Ø150 mm earthen clay pipe with SN16 DN150 uPVC
• Construction of a new 1050 mm diameter manhole to replace the existing lamphole, installed approximately 80 m downstream of existing manhole ELWWMH00715 (the existing lamphole, approximately 112 m from ELWWMH00715, does not comply with current spacing standards)
