On the banks of one of Brazil's largest rivers - the Madeira - riverside families live on less than 50 litres of water a day due to the historic drought that has hit Rondônia.
This is less than half of the 110 litres per day considered necessary by the United Nations (UN) to meet a person's basic needs.
Communities are rationing water or digging holes in the ground to get it.
The cacimbas (wells used to supply the houses) are almost dry.
Another problem is the low quality of the water from these wells for consumption.
To help with treatment, Porto Velho's Municipal Civil Defence is distributing kits of sodium hypochlorite, a substance that ‘cleans’ the water.
There are currently 52 riverside communities, which according to the Civil Defence are the most affected by the drought in Porto Velho.
On Saturday (31) August, the average level of the Madeira was 1.26 metres, when it should have been 4.28 metres.
The river is more than two metres lower than expected.
During the 60 years of monitoring, there has never been such a severe drought, especially in July and August.
Historically, the river level should only reach low levels in September and October.
