The long-awaited HSG282 The control of Legionella and other infectious agents in spa-pool systems was released at the beginning of the year.   Its predecessor, produced by the HSE/HPA, primarily concerned itself with a traditional spa pool in a complex as opposed the increasing trend of domestic hot tubs used in commercial applications such as holiday parks or outdoor cinemas (I’d still like to see how this works!).
HSG282 has a comprehensive design and commissioning section but, in my experience, more could be done at the planning phase to save costs further down the line.
Here are my top 5 tips for installing hot tubs in holiday parks:
  1. Trees and foliage – often hot tubs are correctly installed with privacy in mind however, infectious agents such as Pseudomonas Aeruginosa can be found in foliage. When these fall into the hot tub or surrounding decking they can introduce bacteria into the water which can be hard to manage. Always look up!
  2. Wastewater – hot tubs require chemical disinfection to keep them clean and so the disposal of wastewater must be considered. The ideal solution is to introduce a holding tank which stores water for 24hrs allowing any chlorine to ‘burn off’ prior to disposal.  Hot tubs draining straight to waste or ground could attract the attention of the EHO, kill off grass or foliage and can destroy the enzymes required in waste treatment plants.
  3. Decking – modern plastic decks are easier to clean and reduce the risk of bacteria transfer into the water. Common practice is to super chlorinate the water prior to draining which disinfects the hot tub water system; this water can also be used to clean the deck surrounding the hot tub area.  Wooden decks make this process more difficult and can harbour bacteria which is later transferred to the water.
  4. Access – maintenance teams will require access to hot tubs to test water or to make any adjustments. Allowing for safe, clean access for staff will make the process more efficient in the future; if maintenance teams have to walk across a muddy field and then onto the decking to test the hot tub then there is an increased risk of introducing bacteria into the water.
  5. Showers – it is common practice to request guests to shower prior to entering the hot tub. This means that they must be provided; installing a hot tub on a glamping tent with no running water is a recipe for disaster.
Hot tubs are a great asset for any holiday park and a real attraction for guests, however, the safety implications if poorly managed can include reputation damage, enforcement action, civil claims and even prosecution. Based in Somerset, here at PDT Safety we have years of experience in managing and training hot tub safety in holiday parks.
