Typical household water consumption

The typical household in South African uses about 250 litres of water a day. That amounts to 7500 litres a month which is already more than the monthly free water allowance every household receives from the municipality.

The typical South African household consisting of 3 children and two parents would then use on average 37500 litres of water a month.

Some of the easiest ways to reduce your water bill with out changing you lifestyle at all is to save on water used by toilet flushing and showering and gardening.

The average toilet cistern flushes on average 9 litres with every use and 9 litres are definitely not require to clear the toilet bowl every time. This amounts to a large amount of clean fresh water wastage.

Laundry and bath/shower water can safely be used to water gardens. By collecting both 33% of household water can be reused to irrigate the garden. This brings in a tremendous saving.

With Water Rhapsody water conservation system we can save up to 90% of you water bill. When was the last time you really looked at how much you were spending each month on water?

  • I am looking for a help on more or less how much water can be consumed by a household.

  • This is a tough question to answer as this depends on how many people are living in the home and how much water is used for irrigation. The city of Cape Town uses an amount of 240 litres per person per day. If one is to exclude irrigation then one could look at an amount of 110 to 160 litres per person per day.

    I am confused, the first sentence says that the typical family uses 7500 litre per month, the next says the typical household uses 37500 litre per month?

    I take it that the first sentence is per person, but seems a bit much
    37500 x 29% toilet use = 10875 litre per month for toilet
    = 362 litre per day, divide by 9 = 40 flushes per day, five people = 8 flushes per person per day??
    We flush about 2-4 times per day each.

  • The amount of 7500 is the volume of water that one person would use should they use 250 litres of water a day. Every household receive 6000 litres of free water per month.
    Regarding toilet flushing; modern toilets are fitted with 9 litre cisterns or even 6 litre cisterns, however the bulk of older homes in South Africa still have 13 litre cisterns. This then works out to 5.5 flushes a day which is seen as typical.
