There are a number of infrastructure constraints that impact on the current operations at the Port and on the potential for growth and development of existing and new activities. These include:
Water supply
| The water source serving the Port is currently located on land owned by PTL, with an agreement with TDC for limited water supply under a resource consent held by PTL. Water availability and security is limited for current use, is not currently secure, is vulnerable to weather events and is unable to provide for any potential growth. Future development in the area is dependent on having secure water supply or supplies for a range of demands. |
| The provision of a potable water supply is critical to the anticipated commercial developments associated with the aquaculture industry. It is assumed water for firefighting will be required around the Port area and the commercial area. |
| The current option being explored by Council is to extend the water supply line from Pohara to service the commercial Port area, but this would remain on a limited supply and would be insufficient for more than minimal growth. Options for additional water supply appear limited (few reliable surface water sources available) and may be costly. |
| The area overlays Takaka Limestone and granite which leads to risk of runoff and contamination getting out to CMA due to porosity and erodibility. |
| Options for on-site ground water are being pursued and investigated in relation to quality and quantity. |
Wastewater
| Wastewater at the Port currently discharges to Council’s reticulated network. There is a Council owned pump station at the Port which pumps the wastewater from the Port (as well as from the communities further east of the Port such as Ligar Bay and Tata Beach) to the Takaka Wastewater Treatment Plant. Currently the system is at capacity and TDC are unable to connect new Port facilities or consent new subdivision properties to the system until the system upgrades have been completed (programmed for 2022-2026). |
| The network has a history of wastewater overflows onto private property. Underlying services in that section of the road are due an upgrade. |
| The Pohara Valley Road pump station is sited in the middle of TDC’s legal road. |
| Expansion of wastewater services is critical for the operation and expansion of the commercial Port area and the ability to cater for more aquaculture activities as well as dealing with issues relating to biosecurity. |
| It is possible that some forms of industrial development may only create minimal wastewater from toilet blocks and offices and options could be explored to store it and discharge off peak into infrastructure (existing or future expansion) or transport it off site. Contaminated water from boat maintenance would likely need to be transported off site to an approved disposal location. |
Stormwater
| Stormwater management is not integrated into any network operating within the wider area. Stormwater within the PTL land is managed onsite through infiltration. |
| Stormwater needs to be managed to ensure that contaminants do not discharge into the coastal marine area. |
| Stormwater management is not integrated into any network operating within the wider area. Stormwater within the PTL land is managed onsite through infiltration. |
Future considerations
Other servicing issues may arise over time including the need to increase electrical capacity to the Port to provide for electrification of vessels.
Key issues in providing for infrastructure include:
Current and future spatial and activities issues
There is a need to identify where specific culturally sensitive sites are located within the new and expanded activities need to be located in a way that avoids impacts as much as possible on the environment and residents. Expand for detail:

Provision of sufficient services is necessary to support existing activities and provide for growth/expansion and new activities, however achieving the necessary servicing is limited by accessibility (e.g. a reliable water supply) and funding.
Response to Issues
There are a range of responses that would address many of the issues identified in the Report.
