The City of Cape Town has urged residents and holiday-makers to remain water-wise over the festive period.

The City says the average water consumption increased by 46- million-litres per day to 587-million-litres per day in the past week.

Local authorities say this is still well within the current Level-3 usage range of 650-million litres of collective usage per day.

The levels of dams that supply Cape Town with water have declined by one-point-two per cent over the past week to 68.2%

This is compared to dam levels of 33.1% at the same time last year.
