Project Summary

HIFraser was awarded the task of assisting BAE with the mid-life upgrade of the ANZAC Class Frigate fleet.

Each ship upgrade included the supply and installation of two EVAC OnlineMax vacuum collection units, 4 new dual flush vacuum/emergency flush toilets and 4 new standard vacuum toilets. HIFraser’s project scope also included the supply of a wet waste collection system and holding tank designed by our in-house Engineering team. In addition, two small macerators and one large macerator were installed to manage all food waste from the galley, ward room and scullery with waste collected by the new vacuum system and diverted to a holding tank.

As part of the upgrade, HIFraser also supplied Lorowerk pipework connecting the macerators to the food waste tank, and the toilets to the vacuum collection system.

The team at HIFraser were involved from the project inception including the specification, supply, installation, commissioning and set to work of the systems.

As well as the supply of all the new plant and equipment, HIFraser’s skilled service technicians also carried out an extensive survey and overhaul of all existing vacuum toilets and ancillaries, as well as a full chemical clean of the vacuum and grey water pipework. The ships two sewage treatment plants were also given a full overhaul and rebuild that included new discharge and macerator pumps, pipework and valves. This work ensured that the ship would be returned to the Commonwealth with a near new vacuum collection and sewage treatment system.

Project Overview

HIFraser was awarded the task of supplying a vacuum collection system for this iconic building with the primary use being to collect waste water from mid and high level base building services. The Evac system was subsequently found to be the perfect solution for providing drainage to individual tenancies for their hydraulic services without the need to impact of the buildings complex structure. Connected services included:

  • Level 29 cooling towers, boilers, chillers, and floor wastes
  • Level 16 chillers and floor wastes
  • Level 17 through 28 fit outs
  • Scalability for connecting new services as required.

Benefits

  • With easy access to the vacuum system through capped connections on each level, the building owner can offer access to 100% of the Net Lettable Area (NLA) on tenancy fit‐outs with no limitation on hydraulic services placement.
  • Since the vacuum drainage system lifts waste vertically, there is no requirement to penetrate the slab during ongoing refits after the building has been completed.
  • Using small bore piping, waste is quickly and efficiently transported overhead between existing services to the main vacuum riser and since there is no reliance on gravity, this can be done with very limited loss of grade.
  • The Evac vacuum technology and system design makes fitting out new tenancies simple offering 100% freedom in design and achieves 90 percent water recycling.
