    Hello,

    We are in the process of reviewing our water quality testing. Having re-read the Qld Government Guidelines (2013), I note they also suggest you sample the toilets. We are small one theatre day surgery, and only do elective surgery. We have 17 water outlets (14 x TMV / 3 x toilets). I was just wondering how many samples other similar size day surgeries are doing and their frequency. The Guidelines suggest quarterly, but the Chief Health Officer’s letter suggested annually if you were considered low risk. The Guidelines appear to be geared more towards larger public/private hospitals.

    Are other sites sampling the toilets? Obviously, this isn’t a TMV and I would have to check with the lab how we do this, as you can’t do the triplicate test the Guidelines suggest.

    Look forward to some feedback.

    Regards

    Hi Tina

    My interpretation of the guidelines where it says 2. Collect random samples from other locations such as wash basins, bath tubs, toilets, service taps, sinks, and other water spigots” is that it is looking a cold water inflow (where there is only cold water feed, such as a toilet), not water in the toilet bowl. So, if you want to sample these sites, try getting water from the inflow feeding these devices. And the main idea of looking at cold water would be looking at total plate counts rather than just Legionella, as well as residual chlorine levels, to ensure your water system is maintaining an appropriate disinfectant level when supplying outlets.

    In my mind it is about looking at the whole water circulation system, not just the outlet, and what the water quality is that is feeding each outlet.

    You could also specifically ask the Water Quality team in Queensland Health for any advice on this for your facility, as well. They are quite helpful.

    Cheers

    Thanks Michael. Will contact the water quality team for further advice. We were originally told to just sample the TMVs, specifically showers which are rarely used.
