1.1 This Particular Specification covers the requirements for undertaking planned CCTV inspections of gravity wastewater pipelines in Ōpōtiki. This Specification also covers the removal and disposal of debris and the recording and delivery of CCTV inspection data. The CCTV inspections are to be undertaken in accordance with 3rd Edition of the New Zealand Pipe Inspection Manual – May 2016 (the Manual). This Particular Specification describes amendments to the Manual and provides supplementary information that is specific to this contract.

1.2. PURPOSE
The Ōpōtiki wastewater pipe network has a high level of inflow and infiltration which affects the performance of the network, including the pump stations and the wastewater treatment plant. Manhole overflows occur in wet weather.

It is known that infiltration due to high ground water tables is significant in the deeper sewers. High ground water tables are caused by rain and also high levels in the adjacent rivers.

Ōpōtiki District Council wish to understand the inflow and infiltration problems so that more informed decisions can be made on rehabilitation of the network. CCTV assessment of selected deep sewers is part of this process. The scheduled sewers are to be inspected in order to:

• determine the condition of the selected pipes
• identify joint displacements and leakiness
• assess root growth and fat build up
• identify sewers that have dips/adverse grades

1.3. SCOPE OF WORKS
The contract includes among other things:

1. Locate manholes and CCTV access points.
2. Initial CCTV inspection to determine cleaning treatment
3. Pipeline cleaning (both light & heavy)
4. Debris removal and disposal
5. CCTV Inspection
6. Laser profiling for pipe internal diameter (provisional item)
7. Manhole Inspections
8. Location of the position of any buried manholes, service connections or pipes (using a CCTV camera).
9. Reporting all defects and features identified during the CCTV inspection process.
10. Correcting/updating incorrect or missing asset information.
