Cape Town's water crisis is worsening, sparking fears that taps in the tourist hotspot could run dry.

Dam levels in South Africa's Western Cape province fell from 25.3% last week to just 24.5% this week.

A year ago, they were at nearly 38%.

It had been expected that 12 April would be the date when taps would be turned off, leaving residents to pick up their water from one of around 200 collection points.

Commercial areas, hospitals and informal settlements would be exempt from the restrictions.

Cape Town's city council has announced plans to tighten water restrictions. From February, residents must use less than 50 litres per person, per day in a further effort to avoid a tap turn-off.

Currently, just 55% of residents are using fewer than 87 litres a day, officials have claimed.

Meanwhile, aquifer drilling is accelerating and authorities hope to reduce water pressure in the municipal system in the coming weeks.

On Saturday, hundreds of the city's Muslims gathered for a special service where they prayed for rain.

The city's leaders have also said they are getting tougher on people who are stockpiling water and unlicensed stores selling potable water.

On Tuesday, local media reported that several schools have turned off their taps and asked students to bring water from home.

Some schools, such as Pinelands High School, are switching to a bucket system to save the water used when flushing a toilet.

Others have asked children to come to school in their sports gear so parents do not need to wash two outfits.

Some nursery workers are being laid off, as water-saving efforts leave gardens dry and undeveloped.

Once the restrictions begin, the city's leaders expect them to last up to three months.

Climate change and massive growth in population have been blamed for the water crisis.
