Watercare’s Mangere Wastewater Treatment Plant
The Customer’s Requirement
Watercare is a council organisation, wholly owned by the Auckland Council. It provides water and wastewater services to around 1.3 million people in the Auckland region.
Recently Watercare relocated its head office from 2 Nuffield St, Newmarket to a new building at 73 Remuera Rd, Newmarket. Staff from two other Watercare sites have also been located in the new building. This has meant that space within the building is at a premium, hence a key objective for Watercare was ensuring they had a cabling solution that permited maximum flexibility in the future.
The Customer’s Solution
ITL proposed a Krone Category 6A Unshielded Solution for Watercare’s new premises at 73 Remuera Road Auckland.
The solution was configured so that the structured cabling feeding the environment goes via Consolidation Points located in the ceiling space.
The Customer’s Outcome
Cabling Support
- Installation of compliant cable support where not provided by others. We assume the Electrical contractor is to provide cable tray as per Specification 1.4.4.6. All IT Cables will be attached to the cable support using Velcro Wrap as per the Suppliers Certification requirements
Horizontal Cabling
- Installation of Horizontal cables from the FD’s to the TO’s. The cable we propose is TE Krone Cat 6A. This is compliant with the requirements of the Specification/RFP
Consolidation Points(CP)
- Installation of 25 Way IDC Consolidation Points with spare capacity as requested
MUTO
- Installation of 6 Way KRONE Muto’s. The method for securing these will be finalised in consultation with the client. Options are to secure them to the underside of the desk with fly leads being cabled from the MUTO to the Relevant Desk or mounting these MUTO’s on a Mounting Plate
Cable Droppers
- Installation of Dual Compartment Cable Droppers for Power and IT Cabling
Wireless Access Points

- All ICT cables installed by ITL, will be clearly labelled for easy identification with a permanent wrap around label. Patch Panels will be labelled in accordance with the Specification. These will be identified with a label showing the FD from which they originate.
Documentation CAD / Asbuilts
- Once the Shop Drawings are completed and signed off by the Consultant/Client, they will be used by the onsite Team as “Construction Issue” Drawings. ITL will produce OM / Asbuilt,Manuals “neatly bound in, durable hard backed, permanently labelled vinyl covers”
Testing Commissioning/ Witness Testing

- Check and test the performance of all ‘basic links’
- Test from all FD’s to all TO’s
- Provide written test result schedules of all commissioning tests and checks carried out.
- Individual test results for each ‘basic link’ will be provided
- For the ‘basic link tests only a ‘Pass’ will be acceptable. If the tester returns either a ‘pass*’, ‘fail*’ or ‘fail’ the fault shall be rectified until a ‘pass’ is recorded.
