Care and maintenance of plastic water tanks

Good quality ‘plastic’ or polyethylene water tanks do not require much maintenance over their service lives but there are a few things that will ensure maximum service life is attained.

In the first place, always buy the best quality, rotational moulded poly tanks to ensure that the workmanship is up to standard and that good quality materials are used for the manufacture of the water tank.

Here are a few tips for the care and maintenance of poly water tanks:

  • Ensure that the water tanks are carefully loaded, transported and offloaded after you have purchased them – the majority of damage to plastic water tanks is during this time
  • Always install poly water tanks on flat, level surfaces that are able to withstand tonnes of downward pressure without bending, cracking or subsiding – uneven tank platforms and tank bases can cause damage to the bottom of the water tank when filled with water
  • Make certain that there are no loose structures or objects near to the water tank that could fall onto the water tank and damage the tank’s walls during a high winds or accidental knocking over
  • Most good quality polyethylene water tanks are manufactured with UV-resistant material and can withstand direct sunlight for many years.  Cheaper poly water tanks will quickly fade and crack, especially in the harsh African sun.  Service life may be prolonged if the water tanks are placed in shade or are shaded/protected in some way
  • Ensure that excessively hot water is not stored in plastic water tanks – as a rule of thumb, most polyethylene water tanks can withstand temperatures of up to 40 degrees Celsius; do not store water at higher temperatures for long periods
  • Inspect plastic water tanks for cracks and gouges – these can sometimes be successfully be repaired via plastic welding
  • Do not store fuels or chemicals in water tanks designed for storing water; only use medium duty or heavy duty chemical tanks for this purpose
  • Check that the water tank lid is firmly secured to prevent foreign matter and organisms from entering the water tank
  • If silt-laden or dirty water is stored in the water tank, periodically de-sludge the tank and ensure that any stones or abrasive material is removed
  • Keep plastic water tanks away from fire or other heat sources – polyethylene has a very low melting temperature and will deform is exposed to open flame or high heat

Polyethylene water tanks are generally much easier to care for and maintain than other types of tanks such as galvanised steel tanks.  Water tank stands that raise the water tanks off the ground can ensure the water tanks are protected from vandalism and damage from livestock as well as providing pressure for water reticulation.
