The Tanker foundation in Chennai provides free dialysis to those who cannot afford it. They also provide free fistula surgeries and have a number of other facilities like supply of erythropoietin, lab tests and even transplants to the needy.
They started off by associating with other hospitals and funding dialysis sessions there. They gradually set up their own centers and are currently serving 140 patients.
They have a fund raiser every year and have the famous Tamil cinema actor Suriya as their brand ambassador. Suriya has also contributed generously for this cause.
They also have a branch in Madurai.
