The water level of dams serving Cape Town have dropped slightly to 76 percent while average household consumption has risen, the city council said on Monday.

"The average water consumption for the past week increased from 546-million litres per day to 563-million litres per day," the council said.

The drop in dam levels marks a 0.2 percent decrease from the previous week.

The city warned consumers to try to restrict water usage to a collective 500-million litres a day, until the national water department reviewed restriction levels, probably in December.

"Although the metro has emerged successfully from a crisis situation, consumers are reminded that the permitted usage under Level 5 restrictions is 70 litres per person per day and that the Level 5 tariffs are still on the higher end of the tariff scale. This should be remembered when it comes to household budgeting."

Cape Town recently emerged from the worst drought in living memory.
