Christian Aid is overseeing a project in Marsabit County in the north of the country, which was a hotspot for violence in 2013.
Before then in 2007, violence led to more than a thousand deaths across the country and the displacement of 600,000 people.
Mbaraka Fazal, Christian Aid's Senior Humanitarian Advisor based in Nairobi, said the need for pre-emptive peace building work is particularly important.
She said: "In this election the stakes are very high.
"If the opposition don't win this time they may well become irrelevant so they are especially keen to mobilise the electorate. At the same time, the current sitting government are not ready to give up their political position."
According to Christian Aid, the successful unification of minority tribes in 2013 to side-line the Borana majority led to animosity and deadly violence.
Fazal added: "We are doing a number of things to try and prevent the same thing from happening again.
"Faith leaders have a unique role to play because they are respected by people across tribal groups and are known to be impartial and able to mediate.
"Christian Aid is helping them to facilitate dialogue between different factions to encourage people to recognise other's opinion and see things from a different perspective from their own.
"After any election there will be winners and losers. We have helped to set up local peace committees whose members are selected by the community.
"Faith leaders are working with these groups to identify shared issues of concern. It is hoped that these formal avenues of communication will allow grievances to be addressed instead of physical violence."
Fazal said they were also preparing to send emergency help should conflict flare up.
She said: "We are pre-qualifying suppliers in advance so that if we need to deliver emergency food, water or essential household items we can do that as quickly as possible.
"We're also helping communities to develop their own plans and identify safe havens where they can escape to should violence erupt."
