Resource consent has been issued for the Nelson Regional Sewerage Business Unit (NRSBU) to construct a duplicate wastewater pipeline across the Waimea Inlet between the Monaco Peninsula and Bells Island.
Tenders closed in October and it is expected that work will start in February 2011 with a project completion date in October 2011
The duplicate pipeline will safeguard against the potential failure of the existing estuary pipeline. The existing pipeline is in a poor state of repair and has been assessed as being at a high risk of failure. The environmental implications of such a failure and the resultant uncontrolled discharge of untreated sewage to the Waimea Inlet are considered to be unacceptable and there is an immediate need to address this existing situation.
The proposed duplicate pipeline will follow the route of the existing pipeline from the Monaco Peninsula via Saxton Island to the Bells Island wastewater treatment plant. It will carry the entire Richmond and Nelson South catchment flow across the estuary to the treatment plant, providing a critical link in the regional sewerage network.
