Aboriginal people living with kidney disease in remote communities in Central Australia will benefit from $15.3 million in funding for treatment.

The Purple House in Alice Springs provides dialysis for people with renal failure, and on Thursday, Assistant Health Minister Fiona Nash promised $9 million for it to keep operating for the next three years.

There was also $6.3 million promised for regional infrastructure to help people living remotely.

The money will fund about 16 new dialysis chairs, says Purple House manager Sarah Brown.

People with kidney failure need dialysis three times a week for the rest of their lives, which means many must travel to Alice Springs "and are stuck there until they die", she said.

"It's not only about having people home all the time, having a life and on dialysis, but contributing to the community, working in the community, looking after grandkids and being looked after by their families," Ms Brown said.

People in remote Central Australia are 18 to 20 times more likely to suffer from renal disease than the rest of the population and are 20 years younger when they contract it.

Ms Brown said having dialysis in communities could also help educate people about renal disease and the lifestyle decisions people could make to ensure they reduced their risk of kidney disease.

Purple House will use the new funding to help the communities of Ernabella in South Australia, Ampilatwatja in Utopia and Kalkarindji, and to provide extra support in Santa Teresa and Lajamanu.

Ms Nash also announced late on Wednesday that $10 million that had been promised in 2011 would finally be delivered to develop accommodation in Tennant Creek and Alice Springs for end-stage renal patients from Papunya, Mt Liebig and Docker River who need to move to town for treatment.

"It's not being overly dramatic to say this changes the face of renal disease in Central Australia," Ms Brown said.

"No longer will dialysis be a one-way ticket to town and home for your own funeral. People will have hope, they'll have a reason to stay well to get home ... This is enormous for all of Central Australia and for people whose kidneys are failing now and who are trying to decide what to do."

Ms Nash would not speculate on whether the funding would be extended by a second-term coalition government.
