Commercial Aquatics Australia advises facilities on pool maintenance during COVID-19 shutdown

Commercial Aquatics Australia, aquatic solutions providers across Australia are closely monitoring the COVID-19 pandemic and following the government’s call to close all swimming pools by midnight on March 25, 2020, shared their advice on what to do with their swimming pool during this period. period.

“We understand that a number of private centers ‘just press the emergency stop button’ and go out, as well as a number of government facilities operated by third-party operators are being told their services are not being used. no longer needed and that these facilities were switched off.

“An immediate and complete shutdown of your pool (s) is the last resort and is not recommended as long-term and sometimes irreparable damage can result in both filtration systems and pool structures.

To quote from a recent statement from the Royal Life Saving Society – Australia;

“To the federal, state and territorial and local governments, we urge you to:

  • Take action now to ensure that every swimming pool open on March 1, 2020 is operational, has a skilled workforce, and is ready to reopen when given the green light to do so.
  • This means ensuring that these vital swimming pools and schools are maintained during this time of closure. Abandoned swimming pools are very difficult and expensive to restore. They are subject to damage and failure. Long-term closures will have significant impacts on health, safety and well-being.
  • Make sure that funds are available to retain key operational staff, whether they are directly employed by boards or facility operators. This staff will be necessary to ensure the maintenance of the swimming pool.

First of all, it should be emphasized that the pool filtration and structural designs are generally based on running 24/7, 365 days a year, with constant temperature and water load.

“What we mean by this is that all calculations, product technical data, water balance parameters and geotechnical conditions have been used to ensure that its life meets and exceeds the expected life. You should not empty or shut down a swimming pool and expect it to survive for an extended period of time.

Problems that may arise due to the shutdown of a swimming pool system (full of water);

  • Stagnant water and subsequent microbial growth in swimming pool systems.
  • Risk of infection from biofilm formation in swimming pool, system piping and equipment.
  • Any warranties held may be void due to improper servicing, maintenance and water balance.
  • Pumps, heaters, and other pool equipment can corrode, seize, and jam.
  • Increased risks to operators when restarting the system due to the requirements of handling water filled with algae.
  • Increase in water consumption thanks to the requirement to empty the entire volume of the pool when restarting.
  • The costs incurred to clean the pool before reopening are significant and typically higher than operating the system at reduced capacity.

Problems that may arise due to the shutdown and subsequent emptying of a swimming pool;

  • Structural integrity can be compromised by the displacement of loads in the pool. Whenever a swimming pool is filled or drained, structural movement can occur.
  • Tile, plaster and plaster finishes can become ‘starved’ due to reduced humidity, changes in water pressure and widely varying temperatures that are no longer held constant by the body of water and subjected to outside temperatures.
  • Pools under hydrostatic pressure may lift / float.
  • Many apartment and hotel swimming pools are installed on vibration isolating acoustic brackets or springs, tensioned slabs and the like which will increase if the water is drained (reduced weight load) causing problems with finishes and to the surrounding pipes.
  • The cost and time, as well as any remedial work needed to get the pool back to a safe and hygienic condition, will far outweigh the savings from emptying the pool.
  • Any warranty held may be void.

Our advice during this period is:

  • Contact your pool service provider who can walk you through the specific steps for your system or perform the work on your behalf. We are able to provide facility inspections to examine the condition of your equipment and on-site assistance to prepare your pools for this period of low usage.
  • Chlorination levels can be reduced to a minimum of 1.0 mg / L and pH to 7.6-7.8 (without bather load, disinfection required will reduce significantly).
  • Check chemical concentrations and pH daily and adjust if necessary (ensure logbooks are completed to meet all warranty obligations).
  • Monitor chemical levels to determine revised replenishment requirements (allow additional lead time due to possible supply issues).
  • The heater can be turned off, provided the water is naturally cooled to room temperature. The water should not be lowered more than 2 degrees in any 24 hour period. (Consult your pool maintenance provider regarding draining or bypassing the heating system if necessary).
  • UV and ozone systems can be deactivated.
  • Pool circulation must continue to allow water movement through pool piping, gutters, equipment and balance tanks. This can be reduced to as much as 50% of the design rate. Water flow may need to be adjusted to ensure movement through the full depth of the water.
  • Pool covers can be used, but should be removed every 7 days to allow gas build-up between the cover and the water surface to dissipate.
  • Make sure to continue with regular pool service and maintenance (all required weekly, monthly, semi-annual and annual tasks do not change with COVID-19).
  • Super chlorination in accordance with standard procedures can be performed during this time, but super chlorination at high levels and not reducing the level within the range will void all warranties, whiten pool liners, and affect many finishes, fixtures and fittings. of swimming pool.
  • Take this time to go through all the important / major work required, annual services, downtime, filter media changes, tile repairs and anything else that is not normally achievable without extensive planning around downtime. consumption.
