The burial site for the local Gurkha community is near the Peace Memorial Garden in Cherry Lane Cemetery, West Drayton. There is space for up to 100 graves in addition to 30 column burial units which will house ashes.
A special dedication plaque will be unveiled by the Mayor of Hillingdon, Cllr Catherine Dann. More than 150 members of the Nepalese community are expected to attend the event.
Leader of the Council, Ray Puddifoot, said: "We wanted to acknowledge the contribution and sacrifices that Gurkhas have made for this country, and as Hillingdon Council commemorates the World War 1 centenary it seemed like the right time for us to do this."
In 2009 all retired Gurkhas won the right to live in the UK, following a campaign led by actress Joanna Lumley, whose father served with the 6th Gurkha Rifles.
