Rainwater, according to a study from Monash University, is safe for drinking — with subjects displaying no measurable increase in illness after drinking untreated rainwater. This only means that it is a good idea to use water tanks for collecting rainwater, and use it not only for drinking but for other household purposes as well, such as gardening, bathing, and laundry.
While research suggests that rainwater is safe for consumption, other factors can compromise its overall safety. There is always the risk of a microbiological hazard since its quality is not always reliable, particularly if dry spells succeed the rain events. The chance of contacting illness remains low, but it is still advisable to know the threats that can affect the water’s quality.
Rapid Plas and other water tank manufacturers note that microorganisms can invade the source in the water tank, and this can come from multiple sources. Not all are harmful, but they can lower the water’s safety, while also affecting its taste and colour. The goal is to eliminate or reduce the presence or bacterial, protozoa, and other enteric pathogens. The latter may come from faecal material of mice, rats, birds, lizards (which may be in gutter or tank).
Maintain Water Quality
You can also do a few sensible things to preserve and maintain water quality. Proper design and installation can help as well as the use of roof catchments, guttering, and piping. It is also beneficial to do a systematic analysis for identifying and assessing the hazards that can compromise the rainwater safety and quality. It is also important to choose the right tank construction material that can help achieve your goal.
Avoid or Reduce Contamination
One way to reduce contamination is to make sure that the roof catchment is clean. This is because when the catchment is filled with branches, the birds use the area as a roosting point. All parts of the rainwater tank should also be cleaned and maintained. While the tanks do not require daily disinfection, it is ideal to chlorinate or boil the water if young, sick, and old people will drink it.
It is best to use quality water tanks and keep up with regular inspections. It is best to contact a reliable water tank manufacturer to choose the right one that will suit your needs.
