Landfill Asset categorisation

    ​Comrades, this is one for the waste management experts and other AM gurus!

    I was putting the data for our Landfill facility into NAMS.PLUS 3 based on a recent report we had done and need to categorize the works identified into Renew-Upgrade-New-Expansion-Maintenance, capex, operations and maintenance.
    There were some areas where I could categorise different ways, the ones below are the main ones

    Cell Construction - all NEW, For a cell, is the asset the hole or is it the airspace or both, as one increases the other decreases?
    Rehabilitation of filled cells - which includes cap construction, would you call this Renewal (bringing the ground back to its original state, or New with the construction of the cap or Operational - but Ops won't be in the capex. - or a combination?
    Gas extraction -  is this operations or maintenance? It is done every three years and requires the installation of gas wells,
    After Care - Operations rather than maintenance

    Is a capped cell still an asset or has it been disposed of as you can't use it anymore, but still has aftercare costs!

    Hope someone can help.

    Hi Ashley,
    I'm just doing a condition audit and AM Plan for Waste and Recycling Services so its a bit topical for me at the moment.
    I would suggest the following:
    Cell construction = New. Cost to excavate the cell
    The land asset is a separate non depreciated asset whereas the cell value is depreciated as it fills
    Capping of Cells I have identified as disposal but that's quite subjective isn't it.
    Gas extraction I would call operations as would be water table monitoring
    Capped cell is still a land asset as after some years it could be converted into another facility such as sportsfields.

    Hope that helps. Keep warm!!

    ​Thanks Ross, pretty much how I was thinking. Capping cells as disposal was one thought or is that renewal of the land? I think disposal indicates that the cell is no longer available which is the same as disposal.  It looks like the only renewal you would do at a landfill then is of the plant and machinery used and any structures.

    Maybe the  boffins at the IPWEA publishing department could produce a Practice Note on Waste Management! With the help of the EPA!!

    Hi Ross
    Can I suggest you talk to the Sydney Olympic Park Authority. There are sme significant waste management pits with drainage and capping on the site. EXactly how they are accounted for might be a useful conversation.
