CCTV prior to development handover

    Hello Mates,

    I would like to hear what requirements you have for utility linear asset cctv prior to handover ie water, sewer, stormwater pipelines. I have been told some ask for everything to be cctv'd others only a certain %. I'd like to hear from you as to your organisation's position.

    Possibly others are also contemplating options and I would be happy to share.

    Anne-Maree,

    City of Launceston requires CCTV camera survey of all our stormwater mains in subdivisional work (and we used to do the sewers back before TasWater took over the responsibility for water and sewerage).  I am aware that some other councils only require this for DN300 and above and I have been told in the past that some have chosen not to require it due to push back from developers in the remoter areas of Tasmania where the cost of getting the equipment to site is high compared to the risk (actual or perceived) in not camera-ing the line.

    I would not support our council moving away from this as I was recently able to identify several house connections that were not correctly installed in a residential development and a couple of areas where the pipe had been crushed.

    ​Tweed Shire requires cctv inspection of all sewer pipes at completion of construction of the subdivision works (not just the sewer works) and then a further cctv at the end of the defects liability period.

    Details can be found in our Development Construction Specification C402 available on Council's website Tweed Shire Council - Living and Loving the Tweed

    Here at QPRC (your neighbors) we  require the CCTV and WINCAM reporting on all Sewer and SW infrastructure and forms a hold point within our development specifications.

    There is also a requirement for all lines to have a proving ball to pass though them up to 525mm, all sewer lines are pressure tested however only a 25% of access chamber are vacuum tested and us as the PCA and water and sewer authority nominate the assets for % testing.

    Regards

    Anne-Maree,

    Shoalhaven Water requires all gravity sewers to be CCTV prior to hand over for developer works. If it is only a short section less than 20m we only require a push camera. Anything more needs to be in accordance with WSAA conduit inspection code.

    ​Hello Anne-Maree

    As Sydney Water cover potable water and sewer, we only have to worry about stormwater.

    We require all stormwater that we are to take over to be CCTVed to Aust Water Assoc guidelines and provide us with the recording.

    Need to specify the CCTV standards, so you can reject mobile phone recordings or push rod CCTV in a 450 dia pipe, both show someone has recorded something, but little of any value for checking the pipe.

    I generally look at the recording, rather than the report.

    The work varies between all clean and not damaged to requiring patches that were equivalent to 50% of the number of joints because of the installation and construction damage at joints and along the pipe.

    Other sites the pipes were good, just had a lot of silt in them, so the builders removed that before we accepted the pipes.

    Good luck

    ​Hi Anne Marie,

    Based on my experience at two different utilities Gold Coast Water and Charleston Water System I can offer the following input.  Have the developer or a 3rd party CCTV all Gravity Sewer Mains and Storm Drains. CCTV is cost effective enough method for verifying workmanship on these contributed assets.

    Water Mains and Sewer Rising Mains on the other hand would be better assessed through hydrostatic pressure testing. I would recommend conducting this for all contributed pressurised mains. It is not cost effective to attempt CCTV of these assets due to access restrictions and other risks.  If you would like to see a breakdown of our developer specs for these activities please send me an email ( dupriester@charlestoncpw.com ).   Hope this input is helpful!

    Hi Anne-Maree
    not in my current organisation but in the Victorian Water industry we usually ask for full CCTV of linear assets because sometimes property connections haven't been cut in, joints are not to standard and surprisingly, a pipe might have already failed. The other issue is invert levels and how gradual the fall is of the pipe (or how flat it is). ​
    It depends on the risk appetite and previous experience of Icon as to what will work for you.
    Good luck!
    Kind regards

    Hi Anne-Maree,

    Here at the City of Stirling, we require all newly installed pipes to be CCTV inspected in accordance with Water Services Association Australia's conduit inspection and reporting code; WSA-05.

    We are fortunate in that we have small subdivisions, which we inspect with our in-house Drainage Inspector.  This means we have extreme confidence in the CCTV reports of assets being handed over to us.  It also places us in a strong position to have the developers undertake remedial works prior to acceptance.

    We have had a number of subdivisions where the developer completed relining and patch lining where the pipes failed Appendix F of WSA-05.  Some even commissioned independent reports that verified our findings and found the pipes were also non-conforming to AS4058.

    I strongly recommend that you stipulate that all pipes be CCTV's before handover.

    Kind regards

    I have participated in military base closures in the past where we performed a FULL condition assessment of the infrastructure to be turned over to council.  You have to provide an estimate of the repair/rehabilitation and can only do that if you know all the problems.  If you estimate this cost based on partial information and estimate low, your council will have to cover the difference or worse yet, the system failures.  Much cheaper to perform condition assessment than the repair and social costs of failures.

    Hi Anne-Maree

    When signing off a subdivision we do not require any potable water assets to be CCTV'd.

    Stormwater requirements - vested reticulation (gravity) that is less than 1200mm in diameter requires CCTV
    Wastewater requirements - vested reticulation (gravity) that is greater than 150mm in diameter and longer than 50m in length requires CCTV.

    Laterals are not required to be CCTV'd.

    Cheers
    Clare

    ​HI,
    Some say CCTV is not good enough on its own. I'm pretty happy with it so long as it has the feature enabled to show changes of incline. This is key to finding many faults caused by poor workmanship.
    I believe all pipe assets should have records attached to their asset on GIS. It therefore makes it necessary for 100% of the new assets to be done, not just to be certain of no faults, but to have the full set of records to attach.
    Cheers
    Shaun

    ​Think about where the liability (Risk) lies.
    If you are handing over the asset to the client, having it proofed for integrity prior to HO will reduce comeback.
    If you're the client the same holds true. It is far easier to resolve known issues prior to HO than wrangle with them once they are in use.

    I am aware of requirements for cable ducts to be CCTV proofed prior to HO because this highlights defects before the client inserts their product(s), making remediation simplier. Liquid carrying services can of course be proof tested in other ways.
