A remote Indigenous community in the Fitzroy Valley, in WA's far north, has gone into day two of having no water supply, locals say.

Resident Natalie Davey said on Monday that the situation had been reported to Department of Communities.

In November last year Ms Davey and others reported that their community continued to have water supply problems after they returned home, having been evacuated to temporary accommodation after the major floods in January.

This week the problems came to a head, with no running water for two days - and counting.

According to the Bureau of Meteorology, the maximum temperature in Darlngunaya is expected to reach 40 C on Monday.

Because of a historical loophole in the land tenure, Darlngunaya is classified as self-managing its water, which means the state government has avoided responsibility for water issues.

National Indigenous Times contacted the WA Department of Water, WA Water Corporation and WA Department of Communities for comment.

Communities advised National Indigenous Times that responsibility for water and power in remote communities was transferred to Water Corporation and Horizon Power as of June last year.

Update:

One Tuesday a Water Corporation spokesperson told National Indigenous Times the water supply in Darlngunaya was restored Monday (5 February) following a fuel supply issue with the temporary water system that is being investigated.

"The community has self-managed water services with responsibility for its own water supply infrastructure," they said.

"In partnership with Department of Communities and Department of Fire and Emergency Services, Water Corporation was brought in to repair flood-damaged supply infrastructure in Darlngunaya and three other communities (Bungardi, Loanbun and Burawa) following extensive flooding. Works included installing new power systems and ultraviolet treatment plants at a total cost of approximately $2 million."

The spokesperson said that in Darlngunaya, the largest of the four communities, additional work to install a water tank, pipework and power supply is now expected to be finished by March 2024.

"Once complete, the scheme will return to the management of the community, as it was prior to the floods," they said.

"Darlngunaya is one of around 133 Aboriginal communities across WA with responsibility for its own water services and infrastructure. These are typically smaller communities with an independent water supply – similar to any number of rural properties not connected to a wider water supply scheme."
